Naively structured data is my bane– the desire (and need) to get stuff done so often overtakes the time needed to do things the better way. So, we bootstrap. A long time ago, we managed to load in a few tens of gigs of contour data into PostGIS, partitioned it into 2ft, 10ft, 20ft, 50ft, 100ft and 250ft tables using select queries with a modulus … Continue reading Contours– Structuring PostGIS data for viewing with GeoServer
As we move away from a simple stack of PostGIS/GeoServer/GeoWebCache/Openlayers to wrapping a MapFish print service into the stack, it’s time to think more seriously about optimizing and stabilizing GeoServer. In preparation for this step, I’ve been setting up a series of VMWare ESX-hosted Debian Linux VMs to function as the cluster of geospatial services. Fortunately for me, there’s plenty of great advice in Andre … Continue reading GeoServer Optimization
This is a “wouldn’t it be nice” post– i.e. a I-don’t-have-time-to-write-it-and-everything-else-on-my-list post. Wouldn’t it be nice if in addition to returning GeoRSS, WFS, OGC, KML, etc. GeoServer returned a POV-Ray file? It could be returned as part of a simple GET post like this: http://localhost:8080/geoserver/wms?bbox=2100506,575982,2290532,739026&styles=&Format=application/povray&request=GetMap&version=1.1.1&layers=base:contours&width=800&height=644&srs=EPSG:102722&camera=2195519,657504,1000&look_at=2195029,657004,500 Vector symbolization could be a POV-Ray approximation of the WFS render styles using coordinates and POV primitives. Also, a PHP … Continue reading POV-ray for GIS Visualization
