Ditch Assist Support Zone

Ditch Assist is capable of importing land forming designs in a tab-delimited text format. Our app loads the file into memory and then during operation performs on-the-fly interpolation based on the user's current position to compute an accurate target elevation based on the surrounding points.

If you would like to add a Ditch Assist compatible export format to your application, it should be relatively simple as we've deliberately opted to use a generic text-based format. All we require is a tab delimited text file with 3 columns:

A sample text file with the correct formatting is provided.

For testing, you may download the Ditch Assist App from the Play Store, and load in your generated text files using the Manage Layers button. The app also has a simulator function that will allow you to enter some coordinates and simulate driving across the area - press Start on the Grading Screen and you should see the target elevation value updating as the app calculates the target height based on your design.

IMPORTANT INFORMATION ON FILE SIZE AND POINT SPACING

Currently, we are limited to a maximum of around 20,000 points in the imported file. At 5m point spacing this would be approx. 100ac (40ha) per file. For larger areas, it would be necessary to either split the fields into several sections, or increase the point spacing. Because Ditch Assist performs interpolation of the points, and therefore generates a seamless smoothed surface, there should be no real issues using 10m point spacings, which would allow approximately 450ac (180ha) in one file.
