Innovative Solutions at the Interoperability Day in Toluca Mexico
I attended on the 30th of May the first OGC interoperability day in Toluca, Mexico. The event was organized by the Autonomous University of the State of Mexico (Universidad Autónoma del Estado de México - UAEM). About 180 people attended. I gave a tutorial about Web Feature Services. I was impressed to see various interesting interoperability solutions.
Faculty as a Spatial Data Infrastructure (SDI)
It was noteworthy to see that an SDI can also be applied at an organization level inside a University. The Faculty of Geography at the UAEM presented itself as an SDI. It is a center that has policies regarding the use, publication and processing of geospatial data. This sure is something to think about – SDIs should be thought about not only at the government level, but also inside universities and other publishers of data.
Interoperability with Simple Features SQL in Geospatial Collaboration Centers
Geospatial Collaboration Centers (Centros de Colaboración Geospaciales) is a concept envisioned in 2007 by the Standing Committee for the Geospatial Data Infrastructure of the Americas (Comité Permanente para la Infraestructura de Datos Geoespaciales de las América), at a time when Mexico was president of that committee. Based on this vision, the National Institute of Statistics and Geography (INEGI) developed the collaboration center model for the State of Mexico. The members of the collaboration center agreed on one common model. The data following the common model is stored centrally so providers don’t need to each maintain a separate database. The data is stored in a PostgreSQL server with controlled access to different types of users. The database can be queried and updated using the OGC standard Simple Features SQL. The real advantage of this approach is that the data can be viewed and edited with different editors: ArcGIS, QGIS, and others. This database approach provides transactional capabilities to “power” users, capabilities which would not otherwise be available to them because many of those software products do not support the transactional capabilities provided by the OGC Web Feature Service Interface Standard. The center also made available the data via web services to the public in general.

Open Government and WMS
As part of the Open Government Partnership. Mexico developed “Your government in Maps” (Tu Gobierno en Mapas ) which exposes different types of data to the general public. They made 848 layers using WMS http://mapas.gob.mx.
WMS Complaint Parcel Management System by INFOCAM
Jose Paredes from INFOCAM presented an implementation that allows users and government to easily manage parcel information. It is a client that interacts on the back-end with OCG services and also provides data via OGC services. INFOCAM's Web Map Service interface has been certified as compliant by OGC.

Next OGC Interoperability Day in Campeche 2014
Following the success of this interoperability day a new venue for the next one was announced. INFOCAM signed in to host the next interoperability day in 2014 in Campeche, southeast of Mexico and a world heritage site. I hope to see some of you there, and I hope to see more innovative collaboration Centers using OGC standards!
