Wrapper around rasterio to query points on a Digital Elevation Model
Project description
demquery
Wrapper around rasterio to query points on a Digital Elevation Model.
Features
- Use multiple raster files without having to merge them into a new file
- Query many points at once
- Optional 2D interpolation (linear, cubic, or quintic)
- Reasonably performant by reading the minimal data required from raster
Install
I recommend first installing dependencies with Conda, then installing demquery itself with pip.
conda install gdal rasterio numpy scipy -c conda-forge
pip install demquery
Documentation
from demquery import Query
dem_paths = ['dem1.tif', 'dem2.tif']
query = Query(dem_paths)
# Points must be in longitude, latitude order!
# These points are in Manhattan, not Antarctica
points = [(-73.985564, 40.757965), (-73.968520, 40.778912)]
elevations = query.query_points(points, interp_kind='linear')
