comment How to read Autodesk Spatial Data File (.SDF) in PHP
Provide the code used to actually write the SDF. Any code that reads the SDF after you have written the file can pose concurrency problems at some point.

comment Web mapping software for a huge raster time series?
No, the file should be on the filesystem. No point in using a database. Even just opening a connection will probably take more time than the code above.

comment Completely Brand New to GIS - Help picking technology from the pros
Mapguide is around as a commercial gis web server since 1996. So certainly older than GeoServer, and the age is certainly not a reason to avoid it.

comment Why is my DEM not caching correctly?
What often works in arcgis is using the raster calculator and calculating a new grid with exactly the same values as the old one. Often raster problems are gone when using the new grid. I suppose it recalculates some statistics and caches.
