Data Stewardship in AI, Geospatial, and Security Operations

Posted on 2025-04-30 by Cercana

In today’s AI-driven and geospatially enabled world, data is an organization’s most valuable asset — yet it is often treated as an afterthought until issues arise. Poor data quality, incomplete metadata, and inconsistent governance can quickly derail even the most sophisticated projects. At Cercana, we believe that data stewardship must be intentional, continuous, strategic, and embedded into every phase of the project lifecycle.

Why Data Stewardship Matters More Than Ever

The rapid adoption of artificial intelligence and machine learning means that models are only as good as the data that train them. In geospatial systems, slight inaccuracies — such as misaligned coordinates or outdated basemaps — can cascade into serious operational errors. Furthermore, organizations are increasingly judged not only on the outcomes they produce but also the quality and governance of the data they maintain, particularly under frameworks such as GDPR and emerging AI regulations (Voigt & von dem Bussche, 2017). Effective data stewardship is now essential for both technical success and regulatory compliance.

Research indicates that up to 80% of AI project failures can be traced back to issues of poor data quality (Gartner, 2021). Organizations that invest early in stewardship practices stand a much greater chance of building reliable, resilient systems.

Common Pitfalls When Stewardship Is Ignored

When stewardship is neglected common problems emerge quickly. Disparate data sources lead to inconsistencies that degrade model performance and decision-making. Metadata is often incomplete, particularly for spatial attributes like projection information or temporal validity, limiting future usability. Without lineage tracking, teams cannot verify the origin or reliability of their data, making validation nearly impossible. Additionally, mismatches in coordinate systems, uncontrolled enrichment, and poorly managed access rights introduces risks that compound over time. Without a defined stewardship process even the most promising initiatives can stagnate or fail outright.

Security Risks Tied to Poor Stewardship

In addition to operational challenges, poor data stewardship also introduces serious security risks. Mismanaged datasets can unintentionally expose sensitive information, particularly when metadata or spatial attributes reveal more than intended. Without proper lineage tracking and access control, organizations are vulnerable to unauthorized data manipulation, leakage, or corruption. Furthermore, compliance with emerging security and privacy standards increasingly depends on maintaining disciplined data governance practices (NIST, 2020). Strong stewardship is not only essential for quality and reliability — it is also critical for protecting organizational and national security interests.

Retrieval-Augmented Generation (RAG) systems, which combine data retrieval with AI driven content generation, are particularly vulnerable to a form of attack known as RAG poisoning. In this scenario, malicious or inaccurate data is intentionally inserted into the knowledge base leading the AI to retrieve and generate harmful or misleading outputs. Without strong data stewardship practices, including strict validation, provenance tracking and controlled ingestion pipelines, organizations may unwittingly expose themselves to these sophisticated new threats.

What Effective Data Stewardship Looks Like

Effective stewardship begins with discovery; cataloging all datasets including third-party and open-source feeds. Standardization of schemas, metadata fields and coordinate systems follows, ensuring consistency across applications. Enrichment activities such as gap-filling, normalization, and validation against authoritative sources elevates the quality of data available for analysis. Governance frameworks define who can create, edit, validate and retire datasets, providing necessary accountability. Finally, continuous monitoring using audits and stewardship KPIs ensures that quality standards are sustained overtime (Redman, 2018).

Many modern data platforms implement these stewardship principles using structured frameworks like the Medallion Architecture, which organizes data into Bronze (raw), Silver (cleaned) and Gold (curated) layers. This structured progression enforces discovery, standardization, enrichment and governance practices in a scalable way (Armbrust, Das, Zhu, & Xin, 2021). By applying stewardship systematically across each stage, organizations can build more resilient and trustworthy AI and geospatial systems.

Organizations leveraging open datasets must pay particular attention to validation as not all external sources meet the same quality thresholds required for mission-critical work.

Applying Porter’s Five Forces to Open-Source Geospatial

Posted on 2025-02-06 by Cercana

Introduction

The geospatial industry has seen significant transformation with the rise of open-source solutions. Tools like QGIS, PostGIS, OpenLayers, and GDAL have provided alternatives to proprietary GIS software, providing cost-effective, customizable, and community-driven mapping and spatial analysis capabilities. While open-source GIS thrives on collaboration and accessibility, it still operates within a competitive landscape influenced by external pressures.

Applying Porter’s Five Forces, a framework for competitive analysis developed by Michael E. Porter in 1979, allows us to analyze the industry dynamics and understand the challenges and opportunities open-source GIS solutions face. The five forces include the threat of new entrants, bargaining power of suppliers, industry rivalry, bargaining power of buyers, and the threat of substitutes. We will explore how these forces shape the world of open-source geospatial technology.

Porter’s Five Forces was conceived to analyze traditional market-driven dynamics. While open-source software development is not necessarily driven by a profit motive, successful open-source projects require thriving, supportive communities. Such communities still require resources – either money or, even more importantly and scarce, time. As a result, a certain amount of market thinking can be useful when considering adoption of open-source into your operations or starting a new project.

Porter articulated the five forces in terms of “threats” and “power” and “rivalry.” We have chosen to retain that language here for alignment with the model but, in the open-source world, many of these threats can represent opportunities for greater collaboration.

1. Threat of New Entrants: Low to Moderate

The barriers to entry in open-source geospatial solutions are low for basic tool development compared to proprietary software development. Developers can utilize existing open-source libraries, open geospatial data, and community-driven documentation to build new tools with minimal investment.

However, gaining significant adoption or community traction presents higher barriers than described in traditional new entrant scenarios. Well-established open-source solutions like QGIS, PostGIS, and OpenLayers have strong community backing and extensive documentation, making it challenging for new entrants to attract users.

New players may find success by focusing on novel or emerging use case areas like AI-powered GIS, cloud-based mapping solutions, or real-time spatial analytics. Companies that provide specialized integrations or enhancements to existing open-source GIS tools may also gain traction. DuckDB and its edge-deployability is a good example of this.

While new tools are relatively easy to develop, achieving broad community engagement often requires differentiation, sustained innovation, and compatibility with established standards and ecosystems.

2. Bargaining Power of Suppliers: Low to Moderate

Unlike proprietary GIS, where vendors control software access, open-source GIS minimizes supplier dependence due to its open standards and community-driven development. The availability of open geospatial datasets (e.g., OpenStreetMap, NASA Earthdata, USGS) further reduces the influence of traditional suppliers.

Moderate supplier power can arise in scenarios where users depend heavily on specific service providers for enterprise-level support, long-term maintenance, or proprietary enhancements (e.g., enterprise hosting or AI-powered extensions). Companies offering such services, like Red Hat’s model for Linux, could gain localized influence over organizations that require continuous, tailored support.

However, competition among service providers ensures that no single vendor holds significant leverage. This can work to the benefit of users, who often require lifecycle support. Localized supplier influence can grow in enterprise settings where long-term support contracts are critical, making it a consideration in high-complexity deployments.

3. Industry Rivalry: Moderate to High

While open-source GIS tools are developed with a collaborative ethos, competition still exists, particularly in terms of user adoption, funding, and enterprise contracts. Users typically don’t choose multiple solutions in a single category, so a level of de facto competition is implied even though open-source projects don’t explicitly and directly compete with each other in the same manner as proprietary software.

Open-source projects compete for users: QGIS, GRASS GIS, and gvSIG compete in desktop GIS; OpenLayers, Leaflet, and MapLibre compete in web mapping.
Enterprise support: Companies providing commercial support for open-source GIS tools compete for government and business contracts.
Competition from proprietary GIS: Esri, Google Maps, and Hexagon offer integrated GIS solutions with robust support, putting pressure on open-source tools to keep innovating.

However, open-source collaboration reduces direct rivalry. Many projects integrate with one another (e.g., PostGIS works alongside QGIS), creating a cooperative rather than competitive environment. While open-source GIS projects indirectly compete for users and funding, collaboration mitigates this and creates shared value.

Emerging competition from cloud-native platforms and real-time analytics tools, such as SaaS GIS and geospatial AI services, increases rivalry. As geospatial technology evolves, integrating AI and cloud functionalities may determine long-term competitiveness.

When looking to adopt open-source, consider that loose coupling through the use of open standards can add greater value. When considering starting a new open-source project, have integration and standardization in mind to potentially increase adoption.

4. Bargaining Power of Buyers: Moderate

In the case of open-source, “bargaining” refers to the ability of the user to switch between projects, rather than a form of direct negotiation. The bargaining power of buyers in the open-source GIS space is significant, primarily due to the lack of upfront capital expenditure. This financial flexibility enables users to explore and switch between tools without major cost concerns. While both organizational and individual users have numerous alternatives across different categories, this flexibility does not necessarily translate to strong influence over the software’s development.

Key factors influencing buyer power:

Minimal financial lock-in: In the early stages of adoption, users can easily migrate between open-source tools. However, as organizations invest more time in customization, workflow integration, and user training, switching costs increase, gradually reducing their flexibility.
Community-driven and self-support options: Buyers can access free support through online forums, GitHub repositories, and community-driven resources, lowering their dependence on paid services.
Customizability and adaptability: Open-source GIS software allows organizations to tailor the tools to their specific needs without vendor constraints. However, creating a custom version (or “fork”) requires caution, as it could result in a bespoke solution that the organization must maintain independently.

To maximize their influence, new users should familiarize themselves with the project’s community and actively participate by submitting bug reports, fixes, or documentation. Consistent contributions aligned with community practices can gradually enhance a user’s role and influence over time.

For large enterprises and government agencies, long-term support requirements – especially for mission-critical applications – can reduce their flexibility and bargaining power over time. This dependency highlights the importance of enterprise-level agreements in managing risk.

5. Threat of Substitutes: Moderate to High

Substitutes for open-source GIS tools refer to alternatives that provide similar functionality. These substitutes include:

Proprietary GIS software: Tools like ArcGIS, Google Maps, and Hexagon are preferred by many organizations due to their perceived stability, advanced features, and enterprise-level support.
Cloud-based and SaaS GIS platforms: Services such as Felt, MapIdea, Atlas, Mapbox, and CARTO offer user-friendly, web-based mapping solutions with minimal infrastructure requirements.
Business Intelligence (BI) and AI-driven analytics: Platforms like Tableau, Power BI, and AI-driven geospatial tools can partially or fully replace traditional GIS in certain applications.
Other open-source GIS tools: Users can switch between alternatives like QGIS, GRASS, OpenLayers, or MapServer with minimal switching costs.

However, open-source GIS tools often complement rather than fully replace proprietary systems. For instance, libraries like GDAL and GeoPandas are frequently used alongside proprietary solutions like ArcGIS. Additionally, many SaaS platforms incorporate open-source components, offering organizations a hybrid approach that minimizes infrastructure investment while leveraging open-source capabilities.

The emergence of AI-driven spatial analysis and real-time location intelligence platforms is increasingly positioning them as partial substitutes to traditional GIS, intensifying this threat. As these technologies mature, hybrid models integrating both open-source and proprietary elements will become more common.

Conclusion

Porter’s Five Forces analysis reveals that open-source geospatial solutions exist in a highly competitive and evolving landscape. While they benefit from free access, strong community support, and low supplier dependence, they also face competition from proprietary GIS, SaaS-based alternatives, and substitutes like AI-driven geospatial analytics.

To remain competitive, open-source GIS projects must not only innovate in cloud integration and AI-enhanced spatial analysis but also respond to the shifting landscape of real-time analytics and SaaS-based delivery models. Strengthening enterprise support, improving user-friendliness, and maintaining strong community engagement will be key to their long-term sustainability.

As geospatial technology advances, open-source GIS will continue to play a crucial role in democratizing access to spatial data and analytics, offering an alternative to fully proprietary systems while fostering collaboration and technological growth.

Do You Need a Data Pipeline?

Posted on 2023-05-17 by Cercana

Do you need a data pipeline? That depends on a few things. Does your organization see data as an input into its key decisions? Is data a product? Do you deal with large volumes of data or data from disparate sources? Depending on the answers to these and other questions, you may be looking at the need for a data pipeline. But what is a data pipeline and what are the considerations for implementing one, especially if your organization deals heavily with geospatial data? This post will examine those issues.

A data pipeline is a set of actions that extract, transform, and load data from one system to another. A data pipeline may be set up to run on a specific schedule (e.g., every night at midnight), or it might be event-driven, running in response to specific triggers or actions. Data pipelines are critical to data-driven organizations, as key information may need to be synthesized from various systems or sources. A data pipeline automates accepted processes, enabling data to be efficiently and reliably moved and transformed for analysis and decision-making.

A data pipeline can start small – maybe a set of shell or python scripts that run on a schedule – and it can be modified to grow along with your organization to the point where it may be driven my a full-fledged event-driven platform like AirFlow or FME (discussed later). It can be confusing, and there are a lot of commercial and open-source solutions available, so we’ll try to demystify data pipelines in this post.

Geospatial data presents unique challenges in data pipelines. Geospatial data are often large and complex, containing multiple dimensions of information (geometry, elevation, time, etc.). Processing and transforming this data can be computationally intensive and may require significant storage capacity. Managing this complexity efficiently is a major challenge. Data quality and accuracy is also a challenge. Geospatial data can come from a variety of sources (satellites, sensors, user inputs, etc.) and can be prone to errors, inconsistencies, or inaccuracies. Ensuring data quality – dealing with missing data, handling noise and outliers, verifying accuracy of coordinates – adds complexity to standard data management processes.

Standardization and interoperability challenges, while not unique to geospatial data, present additional challenges due to the nature of the data. There are many different formats, standards, and coordinate systems used in geospatial data (for example, reconciling coordinate systems between WGS84, Mercator, state plane, and various national grids). Transforming between these can be complex, due to issues such as datum transformation. Furthermore, metadata (data about the data) is crucial in geospatial datasets to understand the context, source, and reliability of the data, which adds another layer of complexity to the processing pipeline.

While these challenges make the design, implementation, and management of data pipelines for geospatial data a complex task, they can provide significant benefits to organizations that process large amounts of geospatial data:

Efficiency and automation: Data pipelines can automate the entire process of data extraction, transformation, and loading (ETL). Automation is particularly powerful in the transformation stage. “Transformation” is a deceptively simple term for a process that can contain many enrichment and standardization tasks. For example, as the coordinate system transformations described above are validated, they can be automated and included in the transformation stage to remove human error. Additionally, tools like Segment Anything can be called during this stage to turn imagery into actionable, analyst-ready information.
Data quality and consistency: The transformation phase includes steps to clean and validate data, helping to ensure data quality. This can include resolving inconsistencies, filling in missing values, normalizing data, and validating the format and accuracy of geospatial coordinates. By standardizing and automating these operations in a pipeline, an organization can ensure that the same operations are applied consistently to all data, improving overall data quality and reliability.
Data Integration: So far, we’ve talked a lot about the transformation phase, but the extract phase provides integration benefits. A data pipeline allows for the integration of diverse data sources, such as your CRM, ERP, or support ticketing system. It also enables extraction from a wide variety of formats (shapefile, GeoParquet, GeoJSON, GeoPackage, etc). This is crucial for organizations dealing with geospatial data, as it often comes from a variety of sources in different formats. Integration with data from business systems can provide insights into performance as relates to the use of geospatial data.
Staging analyst-ready data: With good execution, a data pipeline produces clean, consistent, integrated data that enables people to conduct advanced analysis, such as predictive modeling, machine learning, or complex geospatial statistical analysis. This can provide valuable insights and support data-driven decision making.

A data pipeline is first and foremost about automating accepted data acquisition and management processes for your organization, but it is ultimately a technical architecture that will be added to your portfolio. The technology ecosystem for such tools is vast, but we will discuss a few with which we have experience.

Apache Airflow: Developed by Airbnb and later donated to the Apache Foundation, Airflow is a platform to programmatically author, schedule, and monitor workflows. It uses directed acyclic graphs (DAGs) to manage workflow orchestration. It supports a wide range of integrations and is highly customizable, making it a popular choice for complex data pipelines. AirFlow is capable of being your entire data pipeline.
GDAL/OGR: The Geospatial Data Abstraction Library (GDAL) is an open-source, translator library for raster and vector geospatial data formats. It provides a unified API for over 200 types of geospatial data formats, allowing developers to write applications that are format-agnostic. GDAL supports various operations like format conversion, data extraction, reprojection, and mosaicking. It is used in GIS software like QGIS, ArcGIS, and PostGIS. As a library it can also be used in large data processing tasks and in AirFlow workflows. Its flexibility makes it a powerful component of a data pipeline, especially where support for geospatial data is required.
FME: FME is a data integration platform developed by Safe Software. It allows users to connect and transform data between over 450 different formats, including geospatial, tabular, and more. With its visual interface, users can create complex data transformation workflows without coding. FME’s capabilities include data validation, transformation, integration, and distribution. FME in the geospatial information market and is the most geospatially literate commercial product in the data integration segment. In addition it supports a wide range of non-spatial sources, including proprietary platforms such as Salesforce. FME has a wide range of components, making it possible for it to scale up to support enterprise-scale data pipelines.

In addition to the tools listed above, there is a fairly crowded market segment for hosted solutions, known as “integration platform as a service” or IPaaS. These platforms all generally have ready-made connectors for various sources and destinations, but spatial awareness tends to be limited, as does customization options for adding spatial. A good data pipeline is tightly coupled to the data governance procedures of your organization, so you’ll see greater benefits from technologies that allow you customize to your needs.

Back to the original question: Do you need a data pipeline? If data-driven decisions are key to your organization, and consistent data governance is necessary to have confidence in your decisions, then you may need a data pipeline. At Cercana, we have experience implementing data pipelines and data governance procedures for organizations large and small. Contact us today to learn more about how we can help you.
