Use of data retrieved from OGC web services in a GIS
The OGC standard is well supported by GIS software such as ESRI ArcMap and QGIS.
ESRI ArcMap
- Show me how to load a WMS layer into ArcMap
- ArcMap is not able to load a WFS layer without a "Data Interoperability" license.
QGIS
Query examples
Here you may find some example of the possible queries offered by OGC web services.
Please, refer to the corresponding manuals at OGC, either for the WFS or the WMS, for a complete overview of their standards.
