Discovery of Geospatial Information Resources on the Web

Nowadays, the web provides different methods for discovery and retrieval of geospatial information (GI) resources. For an ordinary internet user, the most used information systems to retrieve GI resources are so called spatial browsing systems such as Google Maps. Spatial Data Infrastructure (SDI) provides more detailed information on specific spatial data themes with advanced levels of searching facilities based on a detailed documentation - metadata. Current research activities have reported that so called mainstream web provides many valuable GI resources of several types (e.g. OGC Services, KML data, etc.). They can be discovered using web search engines (SE) such as Google, Yahoo or Bing. The paper describes individual steps of a workflow for an automatic metadata extraction from the information provided by OGC web services and further extensions in order to fulfil the INSPIRE legislation requirements and related standardization for digital geographic information. Additionally a workflow for searching GI resources provided by OGC services on the mainstream web represented by Google SEs is elucidated.
