| - | |Converter|my_db.mdb|Vector Layer| Vector|It will be stored into the datasource defined by the user| | + | | |DataSource |Data Source is a location where to find data (Postgis Database, Microsoft Access Database, Directory of vector files, Directory of raster files and URL)| |
| - | | | | Tabular Layer|Tabular|It will be stored into the datasource defined by the user| | + | | |Connector|It is used to registry an existing datasource (or to create an empty one) into a file called ''datasource.xml'' | |
| - | | | | Raster Layer|Raster|It will be saved in a Directory defined by the user| | + | | |Project File (*.tview) |For each Layer, the ''Project'' file keep a reference to a dataset, SRID and style of visualization (point/line/polygon) of visualization| |
| - | | | |External Tables|Tabular|It will be stored as a tabular layer into the datasource defined by the user| | + | | |Layer Explorer |It lists all Layers referenced in a Project| |
| - | | | |View|Map Display|A ''View'' can be compared to the ''Map Display'' (the view projection is the Map Display SRID)| | + | |Projection|SRID| It is a code given by EPSG to each known projection | |
