A lightweight and straightforward tool to clip Digital Elevation Models (DEMs) using a shapefile or GeoJSON polygon.

Features

• Clip elevation GeoTIFFs using an AOI polygon
• Outputs clipped raster with retained metadata

Installation

1. Clone the repo or download the files:

git clone https://github.com/yourusername/dem-clip.git
cd dem-clip

2. Create a virtual environment (optional but recommended):

python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install the dependencies:

pip install -r requirements.txt

Usage

Make sure you have:

• A .tif DEM file (e.g., input.tif)
• A .geojson or .shp file for the area of interest (AOI)

Then run:

python clip_dem.py --input examples/input.tif --aoi examples/aoi.geojson --output clipped.tif
