NodeGIS: simplificando o desenvolvimento de aplicações web de geoprocessamento.

Abstract

Associated with the ubiquity of spatial information nowadays, several tools which foster the development of web Geographical Information Systems (GIS) have emerged. Although there are a large number of solutions, many are complex, requiring specific skills from developers. Therefore, there is a need for a tool that simplifies the process of developing and publishing a web GIS application, with the advantage of being open source. In our study, we present NodeGIS, an open source tool that provides a graphical interface for the development of web GIS applications, without code writing or complex server configuration. NodeGIS uses a container-based architecture, using REST and facilitating the deployment of a web GIS application. The presented tool allows the user to plot vector maps, perform overlay and customization operations, zooming, panning, tooltip, conventional and spatial attribute queries. NodeGIS can also be used for teaching GIS, requiring no software installation from students.
