forest_data_analysis

For Forest Navigator project

To start

• Download and clone this repository
• Setup conda forge by running as below

conda config --add channels conda-forge

• Create project environment using the file geo_environment.yml

conda env create -f geo_environment.yml -n <give_new_name_if_needed>

conda activate <give_new_name_if_needed>

• Initialise the folder organisation by running _init.ipynb

Clipping forest data layer to country/subregion boundaries

Requirements:

• Forest data layers in .netCDF format, covering a larger spatial extent than the area we want to crop.
• A shapefile containing multipolygon boundaries to use for cropping the forest data layers.

You need to import the module utils to your notebook, then use the function clip_array. Check notebook/forest_cover.ipynb for the example.

The function will return:

• xarray.dataarray for the forest data layer that is cropped into the specified boundaries/spatial extent
• geopandas.GeoDataFrame for the multipolygon boundaries that are used to crop the forest data layer

You can use these layers for plotting, analysis, and to be exported as a GeoTiff.
