Project Goal

The primary objective of this project (2019–2025) was to modernize and harmonize Ethiopia’s geoscientific knowledge base through the creation of a comprehensive national map compendium at scales of 1:1,200,000 and 1:1,000,000. By integrating archival data with new field research, remote sensing, and geophysical modeling, the project aimed to establish a unified geological and hydrogeological map of Ethiopia. Beyond physical maps, the project sought to democratize access to critical data through an interactive ArcGIS-based web application. This digital infrastructure supports evidence-based decision-making in groundwater exploration and sustainable water usage, planning infrastructure and addressing geological hazards as well as fostering international scientific collaboration between Czech and Ethiopian institutions. This open-access initiative provides a scalable framework for environmental protection and sustainable development amidst rising population and climate pressures.

Business Problem Solved

This project eliminates information silos by centralizing fragmented data into a single, harmonized maps, reducing the "search cost" and technical friction for developers and state agencies. A lack of reliable geological data creates "blind spots" in infrastructure planning. By providing high-resolution modeling (1:1,000,000), the project mitigates financial risk for large-scale engineering, soil protection, and hazard management, preventing costly mid-project failures due to unforeseen ground conditions. With rising population and climate variability, the "business" of water management is critical. The project provides an evidence-based framework for groundwater exploration, allowing for precise site selection and sustainable extraction, which is vital for agricultural and industrial stability.

Technology Implemented

For the implementation and deployment of the Geological and Hydrogeological Map of Ethiopia, the project leverages a robust stack of Esri ArcGIS technology to transform static geological data into a dynamic, interoperable web service.
Core Technology Stack
• ArcGIS Server: Acts as the primary engine for hosting and managing the geodatabase. It enables the publication of complex geological and hydrogeological datasets as high-performance Web Map Services.
• ArcGIS Web APIs/Web AppBuilder: Used to develop the interactive "Geological and Hydrogeological Map of Ethiopia 1:1,000,000." This provides the intuitive UI for zooming, panning, and querying feature attributes.
• Spatial Data Management: Advanced cartographic visualization and harmonization were likely managed via ArcGIS Pro/Desktop, ensuring that standardized symbology for geological units remains consistent across both digital and printed outputs.
