Generic and Custom Scouting Maps

1. Description

There are 2 analytics for scouting map:

  • Scouting Maps - Generics: allows generating available scouting maps in Alteia such as RGB, VARI, NDVI, NDRE, MCARI2, CCCI, MSAVI2, CIR, and PRI.
  • Scouting Map - Custom: allows generating custom scouting maps with a specific formula you must join.

2. Scouting Maps - Generics

Note that these maps can also be automatically generated within the photogrammetry process.

2.1 Inputs

Orthomosaic (from RGB sensor for the VARI) or Reflectance map (from multispectral sensor) are required for this analytics.

See below the required bands in the orthomosaic or reflectance map for each scouting map:

  • Bird View (RGB): red, blue, and green bands or RGB band
  • Crop Vigor (NDVI): red and nir bands
  • Green Biomass (MCARI2): red, nir and green bands
  • Greenness (VARI): red, blue, and green bands or RGB band
  • Chlorophyll content (NDRE): red and red edge bands
  • PRI: R570 and R531
  • MSAVI2: nir, red
  • CIR: nir, red, green
  • CCCI: nir, red edge

List of band names by sensor models: Sensor Band Names‍

2.2 Workflow

Step 1 - From the survey page, click on “Analytics”, select your category (Field experiment, Plantation & Forestry, Production field), then search for “Scouting Maps - Generics”.

Step 2 - Click on "LAUNCH".

Step 3 - Select the map used as input: RGB map (RGB sensor) or Reflectance map (multispectral sensor) and click on "NEXT STEP".

Step 4 - Select the scouting maps wanted to generate and click on "LAUNCH SCOUTING MAPS - GENERICS".

Note: Please take care to select only vegetation indices using the spectral bands of your sensor (Beware of indices using multispectral bands if your sensor is RGB). 

After completion, the scouting maps section is appearing in the BASE LAYERS of the left panel.

2.3 Outputs

The scouting map in .tif format is available in the "Download" section and visualizable in the platform. 

3. Scouting Map - Custom

3.1 Inputs

  • Orthomosaic (from the RGB sensor) or Reflectance map (from the multispectral sensor) are required for this analytics.
  • Custom scouting map formula.

3.2 Workflow

Step 1 - From the survey page, click on “Analytics”, select your category (Field experiment, Plantation & Forestry, Production field), then search for “Scouting map - Custom”.

Step 2 - Click on "LAUNCH".

Step 3 - Select the map used as input: RGB map (RGB sensor) or Reflectance map (multispectral sensor), and click on "NEXT STEP".

Step 4 - Type the formula using band names and operators then enter an output name.

OPERATOR OR FUNCTION STRING FORMULA EXAMPLE
Sum + red+nir
Subtraction - red-nir
Division / red/nir
Multiplication * red*nir
Power x**n OR x^n nir**3 OR nir^3
Square Root sqrt(x) sqrt(nir)
Exponential exp(x) exp(nir)
Natural Logarithm log(x) log(nir)
Logarithm log(x,n) log(nir,4)
Cos cos(x) cos(nir)
Sin sin(x) sin(nir)
Tan tan(x) tan(nir)
Acos acos(x) acos(nir)
Asin asin(x) asin(nir)
Atan atan(x) atan(nir)
Pi x*pi red*pi
Parentheses 3*(x+y) 3*(nir+red)
Delete

Please use the band names associated with your sensor. 

Read the article Sensor Band Names‍. 

Step 5 - Click on "LAUNCH SCOUTING MAP - CUSTOM".

After completion, the scouting maps section is appearing in the BASE LAYERS of the left panel.

From there features such as Value at Point to read indices values at any map position or use a Point annotation to extract values are available (read Measurement Tool for more information)‍. The custom map can be exported from the Download section as well.

3.3 Outputs

The scouting map in .tif format is available in the "Download" section and visualizable in the platform.

4. Use the scouting maps

Please read the article Scouting Maps to see how to value the results
