Presentation about the Geolocation Enrichment tools developed by Avinet as part of the LoCloud project. The tool can be used to add geographic locations to existing datasets provided by cultural institutions. It can be used as part of existing workflows by curators, or in crowd-sourcing projects with users finding places and adding coordinates. http://www.locloud.eu

Acomma-separated values(CSV) file storestabulardata in plain-text form.CSV is a common, relatively simple file format, that is widely supported by consumer, business, and scientific applications. Among its most common uses is moving tabular databetween programs that natively operate on incompatible formats. This works because so many programs support some variation of CSV at least as an alternative import/export format.AWeb Map Service(WMS) is a standard protocol for servinggeoreferencedmap images over the Internet that are generated by a map server using data from aGISdatabase.(source: Wikipedia) 9. you may download geocoded data in different formats as:KML (used in Google Maps, Google Earth..)GeoJSON(used in various GIS applications as Open Layers, Google Maps)RDF(for linked data / semantic web / triple stores)CSVWhen you have finished your geocoding process and are happyAnd you are now ready to show your content on a map 10.
