Geospatial Elucubrations: September 2012
http://geospatialelucubrations.blogspot.com/2012_09_01_archive.html
A blog on spatial analysis, raster management in PostGIS and other related things. September 5, 2012. Loading many rasters into separate tables with the PostGIS raster loader. There is no way yet, with the PostGIS raster loader, to load a series of rasters into separate tables. You can certainly load a series of rasters invoking the loader like this:. Raster2pgsql -s 4236 -t 100x100 -I -C -F dem*.* public.dem psql -d mydb. Subscribe to: Posts ( Atom ). Quebec City, Canada. View my complete profile.

A blog on spatial analysis, raster management in PostGIS and other related things. October 22, 2012. Read and write PostGIS rasters with FME Beta now! Reads and writes rasters from and to PostGIS! Safe Software posted a short tutorial in YouTube. FME Workbench provides plenty of other tools to manipulate rasters before writing them to PostGIS or after reading them. You can for example create a mosaic from many rasters, georeference a raster or create a new raster using a map algebra expression. View my c...

Geospatial Elucubrations: Launching the PostGIS Add-ons! A new PostGIS extension for pure PL/pgSQL contributions.
http://geospatialelucubrations.blogspot.com/2013/11/launching-postgis-add-ons-new-postgis.html
A blog on spatial analysis, raster management in PostGIS and other related things. November 18, 2013. Launching the PostGIS Add-ons! A new PostGIS extension for pure PL/pgSQL contributions. I'm glad today to launch the PostGIS Add-ons. You can download the PostGIS Add-ons from my GitHub account. You can contribute to the PostGIS Add-ons with your own PL/pgSQL functions by following the Fork and Pull GitHub model. Just make sure that:. Your function is written in pure PL/pgSQL (no C! You provide some test...

Geospatial Elucubrations: May 2014
http://geospatialelucubrations.blogspot.com/2014_05_01_archive.html
A blog on spatial analysis, raster management in PostGIS and other related things. May 13, 2014. A guide to the rasterization of vector coverages in PostGIS. A frequent question since the beginning of the PostGIS Raster adventure has been " How can I convert my geometry table to a raster coverage. People often describe the way to rasterize a single geometry using ST AsRaster(). Over the years I could identify only two good reasons to do so. The first is to get all your data layers into a single analy...

A blog on spatial analysis, raster management in PostGIS and other related things. December 13, 2012. Duncan Golicher's series of articles on PostGIS Raster. Is researcher in forest ecology at the Colegio de la Frontera sur. And I thought it was worth sharing them here (so I gain a bit of time to write my next long article :). Here are the posts in chronological order:. Installing PostGIS in Ubuntu Natty. Nearest neighbour in POSTGIS. Connecting to a Postgresql data base from R (Ubuntu Natty). Comparing ...

A blog on spatial analysis, raster management in PostGIS and other related things. July 23, 2012. A Slow, Yet 1000x Faster, Alternative to ST Union(raster) in PostGIS! As a first post in this new blog Id like to share an alternative method to merge a tiled raster coverage into a single row raster. For those who followed PostGIS Raster development, you have seen how we now use the very generic ST Union() aggregate function to merge rasters in a very identical way you would merge geometries:.

Geospatial Elucubrations: August 2012
http://geospatialelucubrations.blogspot.com/2012_08_01_archive.html
A blog on spatial analysis, raster management in PostGIS and other related things. August 27, 2012. FME 2013 will soon read and write rasters stored in PostGIS. Will write a reader, a writer and some others functionalities to interact with rasters stored in PostGIS! These tools should be released with FME 2013 and already available in future beta versions of FME this fall. A great news for the PostGIS community! On the GDAL side, thanks to Jorge Arevalo, lots of improvements. Subscribe to: Posts ( Atom ).
