Map should show which buildings are flooded #123

Closed timlinux closed 4 years ago

timlinux commented 4 years ago

When clicking a flood I dont get so see which buildings are flooded in a different colour any more.

timlinux commented 4 years ago

I would like to follow this scheme for visualisation of flooded buildings:

Use a color gradient for flooded buildings based on their vulnerability. Green low vulnerability, red high vulnerability. Have two flooded building layers for any flood event: 1) drawn with a red border are buildings that are in flood class 2 or higher 2) drawn with no border but using graduated colours for vulnerability are buildings that are in the flood footprint but in flood class 1 (low hazard)

The layer selector should let you toggle on or off buildings from the 2 groups as shown below.

@gubuntu comment please

See also #34 - we can close that when we close this

Building's intersected materialized view needs to be populated first so we can have the layer by each flood event. Ping me back/reassign when the layer is done 👍

I made the corresponding PR here: https://github.com/kartoza/fbf-project/pull/148

Layer spec:

Layer name: kartoza:exposed_buildings

Necessary fields for CQL filters:
 - depth_class: id of it's depth class of the building
 - dc_code: district code key from district table
 - sub_district_id: sub district code key from sub district table (sub_dc_code)
 - village_id: village code key from village table (village_code)

Fields for styling (in GeoServer styles)
 - vulnerability_score
 - depth_class
