I have a layer(base layer) with MultiLineString Geometries and now I need to project the layers(overlays) in the base layer from PostGIS using OpenLayers. However, I got an idea how to project table data source into openlayers. I am trying it on topology schema and I am having my layer data in edge_data,node,faces,relations tables. Can anyone guide me how to project my topogeometry into openlayer. And moreover, I am not using any servers except PostgreSQL.
