Title

CALAR: COPING WITH CHANGING SRS

Abstract

In Spain we are currently undergoing a change in our official spatial reference system, from the old one based on the European Datum 1950 to the new one based on the European Terrestrial Reference System 1989.
 
In this situation, the Andalusian goverment (Junta de Andalucía) has detected a lack of open source solutions for the management and reprojection of spatial information between the various commonly used SRS' which meet the requeriments of CNIG (Centro Nacional de Información Geográfica). This led to the development of Calar.
 
Calar is a multiplatform tool that allow users with limited GIS knowledge to reproject GIS files in the most common formats between multiple SRS'. It support both vector formats (such as ESRI's shapefile, Bentley's DGN or Autodesk's DXF) and raster formats (GeoTIFF, ECW, JPEG2000), and it has been designed to require the minimum user intervention.
 
The next milestones in the project are:
* Publish an open Web Service for all the community, so they can use GIS files reprojections freely.
* Extend actual SRS reprojections via Web Service, according to the community needs.
 
Calar is currently in beta, and has been used successfully in several projects. It is available in the software repository of the Junta de Andalucia software repository (http://www.juntadeandalucia.es/repositorio).
