Lapis Geofinder comes with a set of known predefined web service providers. For instance the freely available and for non commercial use of aerial ortho rectified images from PDOK in the Netherlands.

Each predefined web service is stored in the WMS ini file located under the My Documents\Lapis folder.

If you open the ini file you will see it is build up in sections of text separated by an empty line. Each section represent a web service provider and consists of a set of rules representing the parameters required for accessing the data from the corresponding web service provider. The order of the sections from top to bottom is the same order Lapis Geofinder uses to display the names of web service providers in the drop down menu.

Let’s take a closer look at one section.

WMS=NL:PDOK
URL=http://geodata1.nationaalgeoregister.nl/luchtfoto/wms?
Layer=luchtfoto
ImageFormat=image/jpeg;image/png
Version=1.1.1
code=SRS
maxres=0.50
maxwidth=2000.0
username=
password=
epsgcode=28992

WMS=NL:Cyclomedia
URL=…

  1. The first rule holds the parameter and value of the name of the web service provider.
  2. The second rule holds the basic or start URL for retrieving the data.
  3. The Layers rule or line holds the actual layer(s) the web service is servicing separated by a semi colon when more then 1 layer is available. The order of the layers from left to right will be the order Lapis Geofinder uses to pick from, but then from top to bottom. You can freely rearrange the order of the sections and/or layers to your own needs.
  4. The forth rule, ImageFormat, holds the supported image types by the server.
  5. The version of the web service.
  6. The used code. This can be CRS or SRS.
  7. Maxres holds the maximum ground resolution of the map images.
  8. Maxwidth holds the maximum allowed image size of the map images.
  9. Username holds the login account credential for accessing the web map service.
  10. Password holds the password account credential for accessing the web map service.
  11. Epsgcode holds the supported EPSG code which you want to use for the web map service.
