Wagtail based Geospatial Data Manager and backend CMS for geomapviewer
Most national/regional institutions working in weather/climate/DRM sectors regularly produce and disseminate data and information that is Geo-referenced. This can range from forecast model outputs, earth observation data, stations observation, periodic bulletins and advisories and so on. Usually these are shared on their websites and social media pages in static formats, mostly as PNGs or PDFS.
This is an effort to develop an interactive system for managing and publishing Geo-referenced (GIS) datasets. As the institutions produce and share their products in static formats, they can also use packages like this, to make their data interactive.
The package is developed primarily for use by NMHSs at national levels, but can be adapted in other institutions or places that need to visualize their geospatial data.
All the raster and vector datasets uploaded must have time associated with each file.
For netCDF files with time dimension, time is automatically extracted from the file. For Geotiff, each uploaded file must be manually assigned time.
Data management and visualization
- Uploading and visualization of gridded data
- netCDF
- Geotiff
- Uploading and visualization of vector data
- Shapefiles
- Geojson
- Raster Tile serving of raster data using django-large-image.
All
django-large-imagefeatures are available - Vector tile serving using PostGIS MVT Tiles
MapViewer Management
- Management of layers visualized on the geomapviewer
- Control on visibility (public or private) of layers on the MapViewer
Before installing this package, you should make sure you have GDAL installed in your system.
TIP: Installing GDAL can be notoriously difficult. You can use pre-built Python wheels with the GDAL binary bundled,
provided by KitWare, for easy installation in production linux environments.
To install GDAL using KitWare GDAL wheel, use:
pip install --find-links https://girder.github.io/large_image_wheels GDALOther required packages that you will need to install, if not installed already in your Wagtail Project
- psycopg2 - for postgres/postgis database connection
