PostGIS vs ArcSDE: raster load speed test (summary)

30.06.2009 10:14 ·  GIS  ·  postgis, wktraster, arcsde

Let’s summarise what was said in the posts about PostGIS and ArcSDE. The image loading speed tests showed that PostGIS was much slower than ArcSDE.

However, do not forget that WKTRatser is still in an early stage of development (version 0.1.6 at the time of testing) whereas ArcSDE has been around for years. Also, rasters are usually loaded into the database once, so the load speed test is of little practical value. It would be much more interesting to compare the performance of these products when processing rasters. Unfortunately, this is not possible for a number of reasons.
