The study aimed to develop a web-based geographic information system of PSAU which provides a user-friendly system that allows user to search and locate a particular building inside the university. The system is designed to provide information regarding the buildings within the area of the study. Pampanga State Agricultural Ubiversity, having a total land area of 5,088,534 square meters is divided into four (4) major classifications namely: Academic Area, Science and Technology Area, Commercial Area and Agroforestry and Pasture Area. The university is developing rapidly which makes it that every now snd then there is a new building being built. A number of new buildings were built and there are still on-going projects; therefore, the need to update its map is highly recommended in order to keep the people updated too.The web-based geographic information system of PSAU and mapping of the university was made using different GIS application (Google Earth, Qgis and Qgis2web) and other related software to create a simple yet understandable map that can provide information acquired from the different sources. After the study was conducted, the findings show that the system can easily record and update the data files. Locating a particular building is easier by searching the registered name of the building.
