Drawing custom layers in Mapstore

[Ashwin Sankaran]

I'm new to Mapstore and looking for some examples/documentation on adding some custom layers on top of a Base map.

The custom layers are not GIS based and hence im looking for some integration with webGL/Threejs or SVG type renderers. 

Can someone share any info on this ?

An example from Mapbox GL

Hi,

at the moment MapStore doesn't support 3D models.

Hello Lorenzo,

This question still remains on my end. 

I'm not particularly asking about 3d models, but rather the ability to render a custom layer (which can be hardware accelerated ) on top of a Mapstore map.

Hello Ashwin,

MapStore is using Cesium.js render engine for the 3D visualization (Cesium uses WebGL) and OpenLayers for the 2D visualization on desktop (OpenLayer uses canvas 2d),
here on the stable branch 2023.01.xx you can see how MapStore implements different layers for the Cesium renderer.
Inside a MapStore downstream project you could use the Layers.registerType API to register a new layer type.
There is not a specific documentation about this but you could take a look to these projects that implements experimental layer types:

- Experimentation of an alternative GeoJSON layer (import in the main entry file of the app and implementations)

- GeoNode MapStore client integration (import of custom layer and implementation)

We introduced also a way to visualize 3D Model exported as .glb (GLTF binary format) by applying a style point geometries of a layer (available for GeoJSON or Shapefile or WFS layer included in the map)

Hope this helps you,
Stefano
