Search TipsOpen Street Map (OSM)
OpenStreetMap (OSM) is a collaborative project aimed at creating and providing free geographic data. This data can be included in WebMap for use in base mapping.
You can choose from five compatible products; all five use the open source toolkit ‘Mapnik’ to render data as a Slippy Map 
Note: You can also create your own cache of OSM mapping tiles from regular dumps of the whole OSM database at http://planet.openstreetmap.org/
Adding the data
| Field | Is it Optional or Required? |
Description |
|
Name |
Required |
Enter a name that is descriptive of the layer. |
|
Add URL |
Required |
The URL to the OSM tile server; this will be different depending on the type of OSM base mapping you add. Multiple URLs can be added to allow concurrent requests to be made to the server. For more details, see table below. |
|
Spherical Mercator |
Required |
Choose if the map should act as a Mercator-projected map. This allows support for vector drawing, overlaying other maps etc. |
|

Ignore |
This option is unavailable currently in Cadcorp SIS WebMap but has been added in preparation for future development. |
|
Copyright |
Optional |
Copyright text entered here will appear across the bottom left of your WebMap site. |
|
Number of Zoom levels |
Required |
This value is dependent on the added OSM product. (See table below for appropriate zoom level values). |
Required URLs
To add the tiles as a Slippy Map the appropriate URL needs to be passed to WebMap (see table below). To increase the map’s render speed, use multiple URLs to make concurrent requests.
