Custom Composition & Scouting Maps

1. Custom Composition Map

Delair.ai is able to generate any kind of composition (RGB, CIR…) using hyperspectral data for example. The user is able to generate a custom composition map by typing which bands to use, using band name.

  • Band name for multispectral data: red, green, green_b531, blue, red_edge, nir
  • Band name for hyperspectral data: B1, B2…

1.1. Custom Composition Map Generation

Step 1 - Open a Site and the appropriate Survey. Go to Agriculture & Forestry section of Analytics Catalog :

Step 2 - Open the analytic and press LAUNCH :

Step 3 - Select the available Reflectance Map and press Next step button :Step 4 - Input each band and layer output name, then launch processing :


2. Custom Scouting Map

The user is able to generate a custom scouting map by typing their formula using band name.

  • Band name for multispectral data: red, green, green_b531, blue, red_edge, nir
  • Band name for hyperspectral data: B1, B2…

2.2. Custom Scouting Map Generation

Step 1 - Open a Site and the appropriate Survey. Go to Agriculture & Forestry section of Analytics Catalog :

Step 2 - Open the analytic and press LAUNCH :

Step 3 - Select the available Reflectance Map and press Next step button :Step 4 - Input the formula and give a name to your custom map :

Once you have finished, you can check the status :


A notification will inform about process completion, and move the map to COMPLETED section :

2.3. Map Browsing

Go back to Layers panel, in MAPS section, open Scouting maps folder, to browse your custom map :

From there you can use features such as Value at Point to read indice value at any position of the map, or use a Point annotation to extract values. The custom map can be exported from the Download section as well.
