How to create timelapse animations of spectral indices (e.g., NDWI, NDVI)

Subscribe to my newsletter and never miss my upcoming articles

You can now use one line of code to create a Landsat timelapse of a normalized difference index (e.g., NDVI, NDWI) using Earth Engine and geemap. This option will be added to the Landsat timelapse web app soon.

The original Landsat timelapse (band combination: SWIR1/NIR/Red)

Surface water area extracted using the Normalized Difference Water Index (NDWI)

Vegetation area extracted using the Normalized Difference Vegetation Index (NDVI)

Source code:

import ee
import geemap

Install the development version from GitHub

# geemap.update_package()
Map = geemap.Map()
Map

Use the Drawing Tools to draw a rectangle.

Map.setCenter(-74.520409, -8.373150, 12)
Map.add_landsat_ts_gif(label= 'Pucallpa, Peru', bands=['SWIR1', 'NIR', 'Red'], nd_bands=['NIR', 'Red'], nd_palette=['black', 'green'], nd_threshold=0.3, start_year=2000, start_date='01-01', end_date='12-31', frames_per_second=5)
