Bare Soil Model Estimation

1. Description

Note: "Bare Soil Model Estimation" analytic allows the generation of an estimate of the DTM (Digital Terrain Model) in the context of its application in agriculture (mainly related to the calculation of plant height).

For any use outside the agricultural sector, please consult the "DTM‍" analytic.

Similar to a Digital Surface Model (DSM), a Digital Terrain Model (DTM) is a topographic model of the bare Earth. A DTM excludes objects above ground level such as buildings, structures, cars, and trees. Simply highlight elevated objects that you wish to remove from the DSM, and the DTM analytic will automatically remove the associated elevation for these objects. A DTM can be used for a quarry or a mine site to remove unwanted ground objects from an area.

This analytics will generate an estimated DTM of the survey.

The inputs required are a Digital Surface Model (DSM) and the field boundaries or microplots for the objects above ground that will be removed to generate the DTM.

2. Workflow

2.1 Generation

Step 1 - Select the category depending on the project (Field Experiment, Plantation & Forestry, or Production Field) and click on “Bare soil model estimation" analytic or use the "Search" bar.

Step 2 - Click on "LAUNCH".

Step 3 - Select the DSM of the survey in which the estimation of the bare soil will be made.

Step 4 - Select an associated scouting map (RGB or Multispectral).

Step 5 - Depending on the type of project, select the “microplots” or, if running the production field analytic select a vector file for “field boundaries".


Step 7 - Click on "FINISH" to leave the analytics.

2.2 Progress  Completion Status

Step 1 - Click on the "LAUNCHED" tab of the Analytics tab to see that the analytics is in progress.

Step 2 - The platform notifies the user that the analytics is done and in the "LAUNCHED" Tab the process is turned in "Completed" status.
