Dimensions

Raster dimensions are calculated from the number of vertices in the selected DTM mesh, with the help of the set rows-columns ratio.

Ratios:

• 1 : 1

• 1 : 2

• 2 : 1

• Custom: the exact number of rows and columns has to be manually specified

Process

1. DTM properties are collected

2. raster dimensions are calculated

3. DTM vertices are sorted into raster rows (left -> right, top -> down)

4. cell size is calculated

5. intermediate ASC data structure is populated with the collected data

6. data is written to the output file
