摘要：Historical maps represent a valuable resource in reconstructing the natural and builtenvironment evolution. In order to integrate such maps with recent geospatial datasets, in GISenvironment, some preparatory actions need to be taken. This includes scanning, colorenhancement, metadata creation, georeferencing and reprojection. From our experience, whenit comes to collections with a large number of map sheets, these preparatory actions can takea very long time to accomplish.With this disadvantages in mind, geo spatial.org, a collaborative online project aiming tofacilitate the sharing of geospatial knowledge and the discovery and publishing of freegeographic datasets and maps for the Romanian community, started the eHarta initiative.Within eHarta, Web 2.0 geospatial enabled interfaces were carefully designed, using free andopen source software, to allow the community to get involved in old maps publishing.Through these friendly interfaces, the users were able to do basic map preprocessingoperations, fill standard metadata forms and enter georeference control points for thousandsof old maps. The results were published as georeferenced files (GeoTiff) and standard webservices (WMS, WMTS, KML) using a public domain license
