A new feature added as of TerraPhoto 015.005 (CE and v8i/v8) provides the ability to export rendered views in a TIFF+GeoTag file format. These images can then be bundled in a package that can be displayed within Google Earth. In this article, we will walk through this process using Danger Points in a power line workflow as a use case example.
The first step in the process is to create rendered views of the objects, Danger Points for example, that will be included in the Google Earth package. Within TerraPhoto’s general settings tab, activate, or add and activate, the coordinate system that corresponds with the data being used, in this instance Swedish RT90. The coordinate system is necessary so that TerraPhoto can determine the geographic coordinates to assign to the image for display in Google Earth. Next, open TerraPhoto’s Manage Raster Reference and load the orthophoto into View 1 only.
Next we want to setup view 1 as our top view so that the danger points are easily visible. In this instance our danger points reside on a level called “Danger Points” and have a symbology such that they are both bold and visible within the view. We’ve also used the Danger Points dialog to add labels and set them so that they are all on in 3D. Set the Danger Points Level as the visible level and turn off anything else you do not wish to include in the display. At this point, load the LIDAR data into View 1. Turn on only the classes that correspond with what you are trying to visualize. In this example, we are going to load classes 5 (High Vegetation), 22 (Towers), and 30 (Danger Points).
