LiDAR data filtering with GRASS GIS for the determination of digital terrain models

In the last years, the use of every type of Digital Elevation Models has iimproved. The LiDAR (Light Detection and Ranging) technology, based on the scansion of the territory b airborne laser telemeters, allows the construction of digital Surface Models (DSM), in an easy way by a simple data interpolation

wxGRASS: una interfaz gráfica de usuario para la integración de diversos programas libres para SIG

This paper presents a Graphical User Interface, developed with python and the graphic library wxpython, to GRASS GIS. This GUI allows to access several modules with a graphic interface written in Spanish. Its main purpouse is to be a teaching tool, that is the reason way it only allows to access several basic put crucial moludes. It also allows user to organize the elements presented to stress the aspects to be resalted in a particular working sesion with the program

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.(...)

LOCALITZA: una herramienta SIG para resolver problemas de localización óptima

LOCALITZA software is a tool that increases GIS applications possibilities to analyze and solve optimal facility location problems. This system, that it is being migrated from Delphi to Python, allows to evaluate how existing facility supply covers the demand. ON the other hand, it includes the resolution of an elevated number of classic location-allocation models and, in some cases, includes new models

Arquitectura SOA para la integración entre software libre y software propietario en entornos mixtos

Tanto los sistemas basados en software propietario como en software libre tienen vengajas e inconvenientes que hacen que una empresa o institución no pueda elegir, al menos a corto plazo, en una solución global basada en un solo tipo de software. Consecuencia de esto, lo más habitual es encontrarnos con elementos mixtos en lo que la política de software se refiere. (...)
