Enjoyed setting the errorTileUrl flag in a leafletjs map today. A small homage: Continue reading They’ve gone to plaid. (LeafletJS and CartoDB)
2.5D TINs in PostGIS
(edited: changed TIN to TIN Z) (edited again — function already exists as a flag in ST_DelaunayTriangles… .) Uh, I wrote a function for nothin’… As Regina points out in the commments, this functionality was rolled into 2.1 with a flag. Her example: For the record, my code is about 2% slower on a dataset that takes ~50minutes to triangulate . —————————————— Original Post —————————————— … Continue reading 2.5D TINs in PostGIS
UAS (drone) Footprint Geometries Calculated in PostGIS with SFCGAL — for real this time
In my earlier post, I made a claim that SFCGAL was used in this figure: It dawned on my afterwards, while I was using 3D, I hadn’t actually employed any of the analysis goodies that come with SFCGAL. Well, here it is– a footprint as calculated using the view angles and a real terrain model: Here it is compared with the initial calculation: Continue reading UAS (drone) Footprint Geometries Calculated in PostGIS with SFCGAL — for real this time
UAS (drone) Footprint Geometries Calculated in PostGIS — Individual Footprint
UAS (drone) Footprint Geometries Calculated in PostGIS (viewed in QGIS nightly), taking into account relative elevation, bearing, pitch, and roll, this time just one: Continue reading UAS (drone) Footprint Geometries Calculated in PostGIS — Individual Footprint
