Just click the SDK bat and run your commands from there. If you plan to load more data that will change the extent of the set, you’ll want to run the DropRasterConstraints function before load and then reapply constraints with AddRasterConstraints after load.

It’s a bit like if PostGIS would force you to store only full rectangular vector coverage without gaps or overlaps a perfect rectangular topological layer. You can also create rasters from geometries.


Table of Contents 1. Load rasters Massachusetts state plane meters aerial tiles into a schema called aerial and create a full view, 2 and 4 level overview tables, use copy mode for inserting no intermediary file just straight to dband -e don’t force everything in a transaction good if you want to see data in tables right away without waiting.

Use copy mode instead of table insert.

This section uses the command line utility raster2pgsql and optionally the graphical utility pgAdmin. Below are some using a where clause. Example, if you are on windows:. Note that indices including the primary key will still use the default tablespace unless the -X flag is also used.

A complex coverage can lead to hundreds of tables in the database. There are many functions to help with that goal.

Linux users can install PostGIS 2. Apply raster constraints — srid, pixelsize etc.

PostGISRaster — PostGIS Raster driver

Create a batch file, for example loadfiles. There are a plethora of functions to do that. Break up the rasters into x pixel tiles and apply raster constraints.

First you need GDAL 1. Previous versions were buggy and unstable. If you are running the Boundless Server virtual machine on Windows, connect to the virtual machine and follow the Bash instructions.
