Overview
This is a helper module that interacts with the USGS Earth Explorer website for downloading L8 and S2 satellite imagery.
Extra Utilities
Also included are some extra utility scripts used for converting between WRS and MGRS tile systems. Use the shapefile_to_wrs.py script to create a shapefile with all the WRS tiles that overlap with a given shapefile. You can use this WRS shapefile to generate a .csv lookup table going from WRS pathrow to a list of MGRS tiles.
Generate a WRS intersection with arbirtary shapefile:
python shapefile_to_wrs.py -shapefile ./data/canada_extent.shp -wrs_intersects
Generate a csv lookup from WRS to MGRS:
python shapefile_to_wrs.py -shapefile ./data/intersecting_wrstiles.shp -wrs_to_mgrs
Install GDAL
Make sure GDAL 2.X is installed on the system, and then while in your pipenv environment, run:
pip install --global-option=build_ext --global-option="-I/usr/include/gdal" GDAL==`gdal-config --version`
Install Other Requirements
You can use the included Pipfile to install the rest of the requirements after GDAL, run it with pipenv install
Required Data Files
Shapefiles for the WRS and MGRS grids are required to lookup and convert between the two systems. Download the files from here:
grid_files and data directories goes under the main project directory, test_data directory goes under the test directory in the main project directory.
Env Vars for USGS EE Auth
Make sure to set USGS_EE_USERNAME and USGS_EE_PASSWORD to the usernamd and password that you use to access USGS EE.
