In this lesson, explore Landsat imagery with the Esri Landsat app. Analyze vegetation, NDVI, Change Detection, Agriculture, Geology, and more.

Esri Landsat App

First, you’ll open the Esri Landsat Viewer app and become familiar with the notion of spectral band combination.

BandNameWhat this band shows best
1CoastalShallow water, fine dust particles
2BlueDeep water, atmosphere
4RedManufactured objects, soil, vegetation
5Near Infrared (NIR)Shorelines, vegetation
6Shortwave Infrared 1 (SWIR 1)Cloud penetration, soil and vegetation moisture
7Shortwave Infrared 2 (SWIR 2)Improved cloud penetration, soil and vegetation moisture
8CirrusCirrus clouds

4. Click the Vegetation index tool and see the vegetation cover in your selected area.

5. Also you can try different tools, like moisture index, swir, panchromatic, geology, for your requirements.

6. You can use the Bookmark tool to save your project area.

  • Color Infrared: Healthy vegetation is bright red; Bands 5, 4, 3.
  • SWIR (Short Wave Infrared): Highlights rock formations; Bands 7, 6, 4.
  • Geology: Highlights geologic features; Bands 7, 6, 2.
  • Bathymetric: Highlights underwater features; Bands 4, 3, 1.
  • Panchromatic: Panchromatic images at 15m; Band 8.
  • Vegetation Index: Normalized Difference Vegetation Index (NDVI); (Band 5 – Band 4)/ (Band 5 + Band 4).
  • Moisture Index: Normalized Difference Moisture Index (NDMI); (Band 5 – Band 6)/ (Band 5 + Band 6).
  • SAVI (Soil Adjusted Veg. Index): Offset + Scale* (1.5* (Band 5 – Band 4)/ (Band 5 + Band 4 + 0.5)).
  • Water Index: Offset + Scale* (Band 3 – Band 6)/ (Band 3 + Band 6).
  • Burn Index: Offset + Scale* (Band 5 – Band 7)/ (Band 5 + Band 7).
  • Urban Index: Offset + Scale* (Band 5 – Band 6)/ (Band 5 + Band 6).
