Nearmap WMS integration allows users of off-the-shelf GIS and CAD applications to load high-resolution imagery on demand.
To consume Nearmap imagery via WMS, you must authenticate using API Key Authentication.
Once authenticated, your software package will have a way for you to specify:
- The Nearmap layer you want to view
- The coordinate reference system you want to use to view the layer
To display Nearmap imagery, you'll need to tell your GIS or CAD package to load a Nearmap layer in a coordinate reference system that our WMS server supplies it in. This is specified in our layer capabilities file, readable by WMS-enabled software packages, and located at:
The Manage API Keys page of your Nearmap profile contains handy links to our WMS services containing your API Key. Click on the WMS links icon. The following screen will pop up:
Click on the Australia or United States button to copy the WMS link, including your API Key, to the clipboard. Paste it into your GIS application when prompted.
See API Key Authentication for details of creating and managing API Keys.
Image format: use JPEG
Most GIS applications have PNG as the default image format for WMS requests. We recommend that you instead set the image format to JPEG when you set up a WMS connection to Nearmap. Each GIS application will have a means of specifying the image format or image encoding.
JPEG imagery is compressed, whereas PNG imagery is not. Setting JPEG as the image format will result a substantial improvement in performance due to much less data being downloaded, with only a small reduction in quality compared to PNG.
