The source data is in
netCDF format, which we have been processing to
geojson for each parameter attribute and and time-step. This data is then accessed via an api depending on what the user has selected.
It is difficult to stylize a color gradient for the heatmap to accurately reflect levels of the data, and WebGL presents problems for various browsers (and of various versions).
Inspired by the
geojson-vt plugin, our idea now is to render each cell as a
geojson polygon, and update the style (i.e. color and opacity) of those cells according to their values for the current data selection—possibly processing this as vector tiles to improve perfomance.
- netcdf → PostGIS
- grid cell geometries → vector tiles
- user data selection & time-step → query PostGIS for values → style grid cells
What workflow and tools would be best suited to achieve this?
