Checking Terrain and Roughness

Before micrositing, ensure the accurate contour and roughness information is embedded into the map, which is vital for the CFD forecast accuracy.

1. Click the check box before the map object in the project pane. The scope of the map is displayed in GIS.

   The Layer Edit label appears at the left top of GIS.

2. Expand the Layer Edit panel and click the Map tab.
3. Select the content to be displayed in the Content drop-down menu: Roughness or topography.

   The default option is topography.

   Note: If no roughness data is embedded in the map file, no Roughness option is displayed in the menu. Import a roughness file according to Importing a Map.
4. Select Roughness in the Content drop-down menu.
5. Click the Display button to show the roughness of map in GIS.
