We are jointly implementing geoportal of one of rural communities in Poland, together with :
GEOSYSTEMS Polska and Institute of Spatial and Cadastral Systems.
Geoportal will be in full compliance with INSPIRE, GMES and PLAN4ALL. It will use ISO, OGC, INSPIRE, GMES and PLAN4ALL Spatial Planning Metadata Profile, so that, geoportal will allow to publish spatial data and services in the really interoperable way.
To prove it, we will link several servers, incuding (but not limited to) :
- geoportal of municipality,
- county (powiat) geoportal (when it will start to exist - either in 2012 or 2013)
- regional geoportal (when it will start to exist - either in 2012-or 2013)
- geoportal.gov.pl, http://www.geoportal.gov.pl
- geoportal of spatial planning in Poland, a prototype : http://geohub.pl
- european geoportal of http://www.plan4all.eu
