landsat-cogeo-mosaic

Tools to create MosaicJSONs for Landsat imagery.

Overview

A MosaicJSON is a file that defines how to combine multiple (satellite) imagery assets across time and space into a web mercator tile. This repository is designed to be used to create such files, so that they can be used for on-the-fly satellite tile generation, such as with landsat-mosaic-tiler.

Install

pip install landsat-cogeo-mosaic

For CLI commands and some modules, you need additional dependencies:

pip install 'landsat-cogeo-mosaic[cli]'

Create Mosaics

In order to create the mosaic, you need the metadata on where and when Landsat took images, and also the cloud cover of each image. There are a couple ways to get this data. One is to ping the Sat API hosted by Development Seed. This allows you to find the metadata from specific regions and times, and is easier when you're creating a mosaic for a specific region.

Alternatively, for large mosaics it's easier to do bulk processing. In order to not overload the Sat API, I download a file from AWS with metadata from all images.
