Assume we have a well populated PostGIS database with lots of metadata about raster and feature based data. (we are using FME Server, to farm the cloud and other sources and build the PostGIS database).
Now we need a friendly user interface for search and download.
What open source technologies would one use to create a end-user friendly catalog search and download system (web based).Something similar to what is located at: https://catalog.data.gov/dataset
(I realize they just provide pointers to the original source, we would be caching the rasters and the feature in a datalake, and using PostGIS for the catalog/index)
yea, the data.gov uses ESRI, but let's take that off the table.)
If I had to do it by hand, I would use Leaflet or OpenLayers, but since this is such a common need, I wonder if someone has not already put that together).
