I have a large amount of data stored on a postgreSQL database (RDS) with the PostGIS extension enabled. We are currently doing quality assessment of the data and therefore I would like to inspect/share results with my colleagues overseas. I find querying the database and parsing the result to pandas and geopandas in a Jupyter Notebook (Google Colab) extremely helpful. Connecting to the database using ArcMap or QGIS is less ideal since we need a lot of charting functionality (time series).
A caveat is that this method does not scale very well and fails on my dataset due to the number of geometries. Data and visualization happens client-side and the method fails with complex geometries are large geodataframes. I am looking into alternatives with the following requirements:
- interactive (zoom,pan)
- popup (tooltip) with attribute (property) values
- color / style
- handle 16000 geometries, large number of vertices (200MB)
- ideally server-side or serverless design.
- ideally open source.
So far I've looked into
- cartoframes: does exactly what I want except that tooltips are not supported yet.
Other packages that I will look into: 1. Arcgis API for python. 2. Mapbox API for python. 3. mapboxgl-jupyter
