In the second semester of the academic year 2022-2023, we took a course, GmE 203 Principles of GIS, under Prof. Macapinlac and Prof. Ang from the Department of Geodetic Engineering at the University of the Philippines Diliman, and we found ourselves fascinated by the world of Geographic Information Systems. Through the end of the semester, we absorbed interesting things about GIS concepts and technologies. Yet, the pinnacle of our journey in this course was the capstone paper project, wherein we were tasked to bring together all that we had learned and apply it to a real-world scenario.

Fueled by determination and a passion for open-source technologies in the geospatial field, I, together with Honeylyn Carpio collectively decided to embark on a project of significant ecological relevance. Thus, the project “WEB VISUALIZATION AND SPATIAL ANALYSIS OF TREE SPECIES DISTRIBUTION AT UNIVERSITY OF THE PHILIPPINES DILIMAN ACADEMIC OVAL” was conceptualized.

Our approach was comprehensive, ensuring that each step of the project adhered to open-source principles. From data collection to visualization, open-source technologies were at the forefront of our methodology. The very essence of the project was rooted in open-source collaboration and innovation. To begin, we utilized Pl@ntNet for plant identification, a crucial step in understanding the variety of tree species. For gathering location data of trees, Kobotoolbox proved instrumental. The data collected underwent thorough validation using JOSM. Next, leveraging QGIS, we conducted spatial analysis to comprehend the distribution of species. The heart of the project lay in the creation of an online map visualization representing the distribution of tree species around our targeted area. To achieve this, we employed uMap, a potent tool for crafting interactive maps. Finally, to showcase our hard work to the world, we utilized Google Sites (not open-source) to host all our data and map online. The result of our concerted efforts is a compelling testament to the boundless potential of open source technologies. Our project’s final output, accessible through bit.ly/updtrees, stands as a testament to the power and efficacy of open source tools. In conclusion, the realm of open source technologies offers a multitude of possibilities; all it requires is the right tool and a dash of creativity to turn a vision into reality. Through this project, we have not only grown in our understanding of GIS but also developed a deep appreciation for the collaborative, innovative spirit that open source embodies.
