MAPIR new work-flow for calibrating captured NDVI survey images
Mapir has devised a new work-flow for calibrating your captured NDVI survey images to produce normalized gradient maps. This is a huge step in providing affordable, turn-key imaging that can be compared with surveys performed over time and in different parts of the world.
Images of original NDVI MAPIR stitched of a golf course follow as an example:
When you look at the above images, here are a few good things to keep in mind when using MAPIR luts:
- Healthy vegetation shows up as a shade of green, with the darker the shade the healthier it is
- As you go lower in NDVI value, and go from the yellow to orange, to red colors (or to purples if using the color-blind lut) the vegetation will be getting less healthy.
- Pure white is right around the border of no vegetation and bare soil, so just assume no plants are there.
- The gray-scale areas will be bodies of water, roads, buildings and other non-vegetation
- Any blue areas will typically be areas of shaded vegetation which is difficult to assess the health (a reason it’s ideal to capture images when the sun is highest in the sky if possible)

For a better understanding:
“What is a LUT and what are its typical uses?”
LUT means “Look Up Table.” It’s helpful to think of it like a math problem: R= S+L
“R” being your result or what you want to attain.
“S” being your source or what you start with.
“L” being your LUT or the difference needed to make up between your source and your desired outcome.
In all cases of LUT use, the LUT is the means to make up the difference between source and result.
All cases assume the colorist (or you) is grading through a correctly calibrated monitor for evaluation and finishing. LUTs in no way replace proper calibration or color correction. They only assist in the process.
