The purpose of this study is to present Web GIS-based infrastructure resources at the State University of Manado. This study uses the waterfall method or often called the classic life cycle, this approach is a systematic approach. Software development begins with the user requirements specifications and then went through the stages of planning, modeling, construction, and deployment, then topped with complete software support generated. The research methodology used is the waterfall method has several stages: requirements, system design, coding and testing, program implementation, and maintenance. The data source in this research is to conduct a field survey to collect the object of study is all the infrastructure is located on the campus of the State University of Manado. Mapping in the field using the Global Positioning System (GPS) in which all the buildings on campus Unima at coordinates, the latitude, and longitude. Furthermore, to make polygons from each building identified with aerial photographs available in the OpenStreetMap software then analyze using other software namely QGIS 3.02 Girona Version. The design of the infrastructure on campus WebGIS using data flow diagrams serve to demonstrate the scope and limitations of a system being modeled, as well as demonstrate their interaction with the system outside entities. In the data flow diagram shows that outside entities directly associated with Geographical Information Systems are the location of the building, then the design has been formed with the geodatabase already arranged later in the design Web GIS Manado State University. The results showed that there were two main locations from the campus of Manado State University. The main campus is located in the administrative area of Minahasa Regency precisely in the district of South Tondano, known as Tataaran Campus and other campuses located in the administrative area of Tomohon City which is better known as the Faculty of Education. The campus layout area covering an area of approximately 300 hectares resulted in the spread of lecture buildings spread randomly by following the contour pattern formed on the land of the University of Manado campus. From the results of the identification, there are 86 objects in the form of coordinates, forming separate clusters for faculties, head office, institutions, and dormitories. The exposure of this location shows that it needs to be supported by other infrastructure such as clean water, electricity, internet and roads that require high costs if not properly managed. Therefore, it can be concluded from this research that it will help provide information through the design of campus infrastructure so that it is easier to plan and make decisions towards Unima as a smart campus.
