geomanager 0.4.9

GeoManager
Wagtail based Geospatial Data Manager and backend CMS for geomapviewer

Background
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.
Features
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

MapViewer Management

Management of layers visualized on the geomapviewer

Control on visibility (public or private) of layers on the MapViewer

Installation
Prerequisite
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 GDAL

Other required packages that you will need to install, if not installed already in your Wagtail Project

psycopg2 - for postgres/postgis database connection
