The interactive map is a tool to present and enter the location of places.
With the magnifying glass icon in the upper left you can search for (current) places at GeoNames.
Adding new geometries¶
When in insert or update mode of a place you have following options available (can be combined):
- Set a marker/point at the position where the physical thing is located.
- Draw a line connected to a physical objects spatial characteristics, e.g. the course of a road.
- Draw the shape of a physical thing if the precise extend is known.
- Draw the area in which the physical thing is located. E.g. if its precise shape is not known but known to be within a certain area.
The GeoNames ID field can either be manually entered or imported from a map search result.
The checkbox exact match can be used if there is a high degree of confidence that the concepts can be used interchangeably. By default it is a close match, which means that the concepts are sufficiently similar that they can be used interchangeably in some information retrieval applications. Please refer to SKOS for further information.
If you have the module map overlay activated in your Profile, added overlays for places will be visible on the map by default and can be toggled at map layer button at the upper right corner.
To insert new overlays (only available for editors and admins) go to the view of a specific place. After adding an image file in the file tab you can click add in the overlay column to enter coordinates (Easting and Northing) for:
- top left corner
- top right corner
- bottom left corner
of the image to position it on the map. The coordinates need to be in WGS84 decimal degrees (EPSG 4326).
