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.

Can you explain a little more what you want to do? To move between different projections you can use ST_Transform(). Many web-mapping tools use web-mercator - for example the google SRID for web-mapping is 900913. – djq Dec 11 '12 at 23:34
I am trying to project a table data source using GML in OpenLayers. And I am purely using PostGIS functions rather than any other tools/servers. With the help of Topology Schema I am trying and now I have a problem how to make topogeometry – SriRamaChandra.G Dec 12 '12 at 5:39
from a table geometry which I have in query. I am not sure that whether going in a respected direction or not. Please guide me how to project a topological layer in OpenLayers via GML functions or any other way. I gone through functions like toGML()....etc. More idea requested. – SriRamaChandra.G Dec 12 '12 at 5:39
