Resonant GeoData Imagery

A submodule of Resonant GeoData for storing imagery supporting annotations and spatial reference.

Installation

Follow the instructions for the core django-rgd app first, then

pip install --find-links https://girder.github.io/large_image_wheels django-rgd-imagery

Add this app to your INSTALLED_APPS along with the core RGD app:

INSTALLED_APPS += [

Configurations

The RGD imagery submodule has an optional setting:
