Geographic Information Systems (GIS) are rapidly moving to web-based applications that offer specific geo-processing functionality and transparently exchanging data. Interoperability is at the core of this new web services model, which is enabled by compliance with Open Specifications (OS). Open Source Software (OSS) provide a no-cost software alternative to proprietary software operating systems, web servers, and Relational Database Management Systems. We tested the potential of the combined use of OS and OSS to create web-based spatial information solutions to support land use planning in Mexico with web-based geo-processing capabilities currently not present in commercial web-GIS products. We demonstrate how the process is straightforward and can be accessible to a broad audience of geographic information scientists and developers.
