I work for a city government that has LiDAR derived DEM rasters which we would like to make accessible to other departments in the city. The problem is that many departments don't have anyone with GIS skills and/or licenses. We are looking to develop a simple, easy to use application that will just return elevation values from the DEM based on cursor click/point location. We would like to do this without having to serve out the high resolution DEM dataset for speed and ease of use of the application.
We currently have GeoPDFs that can return elevation data as long as users have the TerraGo toolbar installed. This is expensive and extremely cost-prohibitive so we are looking for a cheap option that can be used by employees and the public alike. We are just looking to query based on XY location of a point which will return the elevation value based off of the DEM. Has anyone done this or have advice on the best way to proceed?
We do have access to Google Maps Engine (the Elevation API is SRTM so resolution isn't good enough for our purposes), as well as ArcGIS Online.
Also worth mention: We are currently running Oracle Spatial but are transferring to SQL Server 2012 with ESRI's LGIM for our spatial data(geodatabases and feature classes).
