Dynamically rendering false-color indices¶
Planet's Surface Reflectance Basemap products are also available in false-color visualizations to support a wider range of analysis. Currently the following seven band combinations and indices available via Tile Service:
- Red-Green-Blue (RGB)
- Color-infrared (CIR)
- Normalized Difference Vegetation Index (NDVI)
- Normalized Difference Water Index (NDWI)
- Visual Atmosphere Resistance Index (VARI)
- Modified Soil-adjusted Vegetation Index (MSAVI2)
- Modified Triangular Vegetation Index (MTVI2)
- Triangular Greenness Index (TGI)
NOTE:
False-color indices and band math visualizations are available only on Surface Reflectance basemaps.
Remote Sensing Indices & Legends¶
| Index | Formula | Legend | URL Parameters |
|---|---|---|---|
| NDVI | \(\frac{ir - r}{ir + r}\) |  |
?proc=ndvi |
| NDWI | \(\frac{g - ir}{g + ir}\) |  |
?proc=ndwi |
| MSAVI2 | \(\frac{2 * ir + 1 - \sqrt{(2 * ir + 1)^2 - 8(ir - r)}}{2}\) |  |
?proc=msavi2 |
| MTVI2 | \(\frac{1.5 * ( 1.2 * (ir - g) - 2.5 * (r - g)}{\sqrt{(2 * ir + 1) ^ 2 - (6 * ir -5 * \sqrt{r})} - .5}\) |  |
?proc=mtvi2 |
| VARI | \(\frac{g - r}{g + r - b}\) |  |
?proc=vari |
| TGI | \(\frac{(120 * (r - b)) - (190 * (r - g))}{2}\) |  |
?proc=tgi |
