Converts pre-tiled vector output from from the PDG viz-staging step into a series of GeoTIFFs and web-ready image tiles at a range of zoom levels. View the content under example to see the type of output produced. Most parts of the process are configurable, including the methods used to summarize vector data into rasters, the color palette, and the size of the tiles. See the documentation in ConfigManager.py for more details.

Install

Requires Python version 3.9 or 3.10 and libspatialindex or libspatialindex-dev

1. Follow the instructions to install libspatialindex or libspatialindex-dev
2. Make sure that Python version 3.9 or 3.10 is installed (try which python3.9).
3. Install pdgraster from GitHub repo using pip: pip install git+https://github.com/PermafrostDiscoveryGateway/viz-raster.git

Usage

1. Create a config JSON file for the raster job, see PDG-Staging docs for details, help(pdgstaging.ConfigManager) for all configuration options, and pdgstaging.ConfigManager.defaults for default config values.

From the command line:

• run: python -m pdgraster -c '/path/to/config.json'

In python: See example/main.py for a complete example.
