SIGFRUT: aplicación web para el diseño de plantaciones e instalaciones agrícolas

The SIGFRUT project is set within what we could call GIS applications in a web environment. (The acronym GIS is SIG in Spanish). We are all familiar with Internet map servers or IMS, with which we can visualize different thematic layers, check their attributes and, in the best cases, consult a data base, selecting and visualizing the elements that meet the required conditions. Nevertheless, these types of applications are basically simple map viewers and do not have any more functional features than the classic tools of visualization and consultation.(...)
