mapblinker

Blink comparison of satellite imagery

Requirements:

1. rasterio
2. pyproj
3. numpy
4. matplotlib

Installation instructions

1. Install miniconda (https://docs.conda.io/en/latest/miniconda.html). Choose the 64-bit Python 3.8 or 3.9 and the appropriate operating system. Follow the instructions to create a base environment and activate it. Make sure you install conda in a location where you have permissions to read and update the packages.
2. Create a new conda environment. Lets call it geotiff. conda create -name geotiff
3. conda deactivate
4. conda activate geotiff
5. Install rasterio pyproj and other things:

conda config --add channels conda-forge

conda config --set channel_priority strict

conda install -c conda-forge gdal -n geotiff

conda install pyproj -n geotiff

conda install rasterio -n geotiff

conda install numpy ipython matplotlib -n geotiff

6. More detailed instructions here https://rasterio.readthedocs.io/en/latest/installation.html, https://pyproj4.github.io/pyproj/stable/installation.html,
7. Clone the mapblinker git repo: git clone git@github.com:shriharshtendulkar/mapblinker.git
8. Copy the data (Email me for the link)
9. Go to the mapblinker directory. Edit test_script.py so that the file paths are pointed to the correct location. Save the changes.
10. Run the code in the terminal: Execute python test_script.py in the same directory as mapblinker.py
11. The code will print some statistics and numbers on the screen and after a while a matplotlib window will show up. If you click at a location, the coordinates of the location will be printed in the terminal. A snapshot image of the surrounding 100m x 100m is also saved in the same directory.
12. If you type n or N, you'll go to the next image. If you type q or Q, the program will quit.
