Creating imagery & terrain corridors (for roadwork and railroad projects)

In this tutorial we will describe the process of importing imagery or terrain alongside a specified band into AutoCAD. This Plex.Earth feature can find many applications when designing roads, railroads, river routes, bridges etc and will result in a much faster procedure. 

Take the following roadwork project, for example.

By choosing to import imagery with the standard "By Area" method, 99 tiles are required. In comparison, when using the "By Path" option, only 35 tiles will be needed, thus greatly reducing the importing time.

Here is what you need to do in order to import imagery/terrain along a corridor:


Step 1: Choose Provider and Import Method

- Choose "Import Imagery" from the "Imagery" tab, on the Plex.Earth ribbon.

- Select your provider and click "Choose >" under the "By Path" option.

Step 2: Define your Axis & Swath Width

- Specify a polyline for your axis (center polyline), or choose an existing polyline in your drawing. Your imagery will follow the path of this polyline.

- Then, you will be asked to determine the width of the corridor on either side of this axis.

Step 3: Import your Imagery

- When prompted, proceed with the import.

- Your imagery will now cover a band along the centerline polyline, with the specified width on each side.


Keep in mind that you can follow the same procedure for importing terrains, by selecting again "By Path" in the "Import Terrain" window of Plex.Earth.
