Construct 3D Buildings from OSM Data

Our software uses OpenStreetMap (OSM) data to create realistic looking 3D buildings on the Map View. The user can view the 3D buildings as well as download the 3D buildings as polygon shapefile data.

Note: Please note that OSM 3D building data might not be available for all the locations.

Viewing 3D Buildings

To view the 3D buildings on the Map View, follow these steps:

  1. From the View ribbon menu, click on the Show 3D Buildings menu item and then the Show 3D Buildings command.
  2. From the Map View toolbar, switch to 3D view mode by clicking on the 3D command.
  3. From the Map View toolbar, select the Rotate View command.
  4. Click and drag to rotate the Map View into a 3D view. As you zoom into a region, 3D buildings will be displayed on the Map View.

Downloading 3D Buildings

The software provides an option to download the 3D building data as a GIS shapefile. In that way, the building data can be utilized for other purposes—such as determining flow blockages, etc.

To download 3D buildings as a shapefile, follow these steps:

  1. From the View ribbon menu, select Show 3D Buildings menu item and then 3D Buildings Download command.
  2. The 3D Buildings Download dialog box will be displayed.
  3. In the 3D Buildings Download dialog box, specify the following:
    • General Specifications
      Specify the layer name and the file directory path for the downloaded polygon shapefile containing the 3D building data.
    • 3D Buildings Data Boundary Limit
      Specify the boundary limits (map area) in which the 3D buildings should be downloaded. Choose an option:

      • Current screen limits
        The software will download the 3D building data for the area that is currently being displayed on the screen.
      • User-defined limits
        Click the [Pick] button. The software will prompt you to manually select a rectangular region on the Map View to download the 3D building data. The Map View will switch to 2D View Mode while selecting this region.
      • Model extents
        The software automatically selects the area enclosed by the model.
  4. Click the [OK] button.

The software will download the 3D building data as a shapefile. Depending upon the region extents selected, downloading of the data may take some time.
