Set up OGC Services

The Open Geospatial Consortium (OGC) provides simple protocols for:

  • Requesting map images from one or more distributed geospatial databases (WMS or the Web Map Service).
  • Requesting geographical features independent of platforms (WFS or Web Feature Sevice)

To use them on WebMap, data using these protocols should first be loaded using GeognoSIS Manager.

Note: You can add raw data files and SWDs; however we strongly recommend SWDs as they are configurable and can hold multiple overlays.

WMTS is ideal for for basemapping as this changes less frequently and a cache of tiles is built over time as the WMTS layer is used.

  1. Set up a new instance on GeognoSIS manager. Click here for more information
  2. Click Edit.
  3. Click Upload Map from the action button and select your SWD.
  4. Once the data file has been loaded, click Options and tick the OGC Web Map Tile Services checkbox.
  5. Click Submit.

WMS can be used for more dynamic map layer datasets

  1. Set up a new instance on GeognoSIS manager. Click here for more information
  2. Click Upload Map and select your SWD.
  3. Once the data file has been loaded, click Options and tick the OGC Web Map Services checkbox.
  4. Click Submit.

Note: You can use data files instead of SWDs to set up Web Map Services. However you may experience some loss of functionality e.g., scale thresholding.

To view the data files right click on OGC Web Map Service and choose Refresh. To view an individual data file, click Preview on the uploaded map. To view all WMS maps, go to Web Services > OGC > Web Map Service and click the View button.

WFS is particularly handy for small or light datasets.

Setting up data to be served out via WFS is similar to setting up a WMS; follow the steps detailed above.

Once you have loaded the data, remember to click Properties and tick the OGC Web Map Services checkbox.
