The Data Manager can be used to download high-quality 30m terrain data for your analysis region directly from our servers.

You will need to install the Data Manager before you can access any of the functions it provides, and you will also need to set the Analysis Region to the area of interest before the download can start.

Once you have set your analysis region, the quickest way to load and visualize terrain data from the Data Manager is by adding a terrain map. From the Start Page select Maps:

The Map page selector

Then press the Add button:

Add Map button

This will give a list of different map types to add. Select Distance Map from the list:

The Map page selector

We add a Distance Map because terrain data is a raster of distance values. Once the new distance map is added, its properties are shown. Expand the Data Source property and press Edit List:

Edit Data Source

This opens the Distance collection editor, and shows all the Distance GeoData providers defined in your project. Now you can add the Data Manager terrain provider by selecting "Terrain (Data Manager)" from the Add selector:

Add Vector Map

The new terrain provider has properties that control the location of the data cache and interpolation options, but none of these need changing from the defaults. Click OK to add the new terrain provider and close this dialog. This will return you to the properties for the distance map. Pressing the Show On Map button will start the download of the terrain data for the analysis region and will make the map visible when it completes.

Add Vector Map

The terrain data is cached on the disk so the download for any particular region will only be done once. You can track the progress of the download from the Status Bar and the Event Log.

Organization

Overture maintains a separation between the data (in this case the terrain data) and the visualization component (in this case a distance map) to allow the user to add multiple map views for a single data source.

Remarks

Terrain data can be used for a variety of RF planning tasks, including RF prediction modeling. Overture's Presto prediction models are ideally suited to using the terrain data from the Data Manager.
