CatAtom2Osm README.md file

Conversion Tool of the data sets of the INSPIRE Services of the Spanish Cadastre (http://www.catastro.minhap.gob.es/webinspire/index.html) to OSM files.

Build environment:

  • Ubuntu 16.04
  • Eclipse Platform 3.8.1
  • GeoTools 16.1
  • JDK 1.8

In order to build the application, the following GeoTools JAR files shall be included in the "Java Build Path > Add External Jars" window of the "Project Properties" in Eclipse:

  • gt-api-16.1.jar
  • gt-epsg-hsql-16.1.jar

The application shall be launched as "CatAtom2Osm ", where the argument path states the directory where the source files are located. The directory name shall start with 5 digits (GGMMM) matching the Cadastral Provincial Office and Municipality Code.

The directory shall contain three ZIP data files downloaded from the INSPIRE Services of the Spanish Cadastre:

  • A.ES.SDGC.CP.GGMMM.zip (Cadastral Parcels)
  • A.ES.SDGC.BU.GGMMM.zip (Buildings)
  • A.ES.SDGC.AD.GGMMM.zip (Addresses)
