Landsat Timelapse

Download Landsat imagery covering Pucallpa, Peru from 1984 to 2022.

2
url = "https://opengeos.org/data/landsat/peru.zip"
leafmap.download_file(url)

The downloaded zip file contains 38 Landsat images covering the area. They have been unzipped and saved to the peru folder. All GeoTIFF files under the peru folder will be used to create the timelapse animation.

1
images = "peru/*.tif"

Each imagery contains four bands, including SWIR1, NIR, Red, and Green. First, let's create a Landsat timelapse using the SWIR1/NIR/Red bands.

You can also create a timelapse using Cloud Optimized GeoTIFF (COG) files hosted on the web. The following example uses some COG files hosted on GitHub.

years = [str(year) for year in range(1985, 2021, 5)]
years

images = [f"https://opengeos.org/data/landsat/{year}.tif" for year in years]
images

If the original image size (shape) is too large, you can use the size parameter (rows, cols) to resize the image. The following example resizes the image to (300, 550).

2
url = "https://opengeos.org/data/naip/naip.zip"
leafmap.download_file(url)

The downloaded zip file contains 10 NAIP images covering the area. All GeoTIFF files under the naip folder will be used to create the timelapse animation.

1
images = "naip/*.tif"

The images cover the area from 2009 to 2020 annually except 2011 and 2013. Each image contains four bands, including Red, Green, Blue, and NIR.
