🛰️ LambdaGEO — Computing and Geotechnology Research Group

Welcome to the official repository of LambdaGEO, a research group dedicated to developing innovative solutions in Geoinformation, Geotechnologies, Spatial Modeling, Applied Computing, and Linked Data. Our mission is to produce scientific knowledge and open-source technologies with significant social and academic impact.

Based at the Federal University of Maranhão (UFMA), the group is affiliated with the Graduate Program in Environmental Science & Technology (PPGC&TAmb).

👨‍🏫 Leadership

Professor Sergio Souza Costa is an Associate Professor of Computer Engineering at UFMA. With a PhD in Applied Computing from the National Institute for Space Research (INPE), his work focuses on Geoinformation, Environmental Data, Web Systems, and LUCC (Land Use and Cover Change) Modeling.

Note to students: I use Notion for detailed lecture materials and mentorship guidelines. You can access my workspace here: profsergiocosta.notion.site

🔬 Research Interests

Our team conducts theoretical and practical research across several domains:

• Geoprocessing & GIS (Geographic Information Systems)
• Geographic Data Science
• Environmental Modeling
• Software Engineering
• Linked Open Data (Semantic Web)

📦 Key Projects & Software

We actively develop tools to bridge the gap between environmental data and web technologies:

• DBAcademic: Connecting public open data from educational institutions.
• DBCells: An architecture for publishing modeling data as Linked Data.
• QGISSPARQL: Tools for integrating Triple stores with QGIS (Triple2Layer & Layer2Triple).
• SiMPoT: Simple Object-triple Mapping for easier data integration.

🌟 Acknowledgments

We are grateful to all the students, collaborators, and partners who contribute to LambdaGEO’s initiatives. Whether through Master’s dissertations or Undergraduate Research (IC), your work drives our progress.
