[postgis-users] Postgis rasters in OpenLayers?
Can anyone tell me if Postgis rasters can be displayed in OpenLayers? We are trying to develop a web-gis stack (so far Postggresql - Postgis - PhP -OpenLayers) on an external server. I'm wondering if we can have raster functionality as well as display with postgis alone as the map server...without using Geoserver of Mapserver. Thank you, Vishal Vishal K.

Re: [postgis-users] Postgis rasters in OpenLayers?
I don't think there is anything in OpenLayer able to speak directly with PostGIS... You need something in between able to deliver tiles. If your php code can do that... But why trying to reinvent a tile server other than MapServer or GeoServer?

Re: [postgis-users] Postgis rasters in OpenLayers?
Thanks Dave, Pierre, There were a couple of reasons for my qn: For an earlier application, we used postgis as a map repository and geoprocessor, php to interact dynamically with the map repository and perform gis operations, R to create graphs, and google earth as the visual frontend. http://108.195.205.37/kml/DataGrid.kmz So I wanted to check if with OpenLayers instead of Google Earth as the client, I could do the same and just have a sparse geospatial stack. Another reason is that we'll need to find a hosting provider and are wondering if we can find one with all the capabilities or flexibility to put up experimental versions of software and have all these individual software hosted. One other qn I had was : Can Geoserver 'speak' with Postgis 2.0 rasters? Thanks again!

Re: [postgis-users] Postgis rasters in OpenLayers?
So I wanted to check if with OpenLayers instead of Google Earth as the client, I could do the same and just have a sparse geospatial stack. The answer is in your php server. You decide... Everything depends on what is supported by the client. You had to develop a server for Google Earth. There are plenty of server for OpenLayer. If you develop your own then there should be no problem. What you need is to serve JPEG and PostGIS raster ST_AsJPEG() will help you to do that. One other qn I had was : Can Geoserver 'speak' with Postgis 2.0 rasters?
