Switch Between GDAL Versions #

I’m a big fan of QGIS and use it all the time. It’s gotten so stable and fast. It is such a joy to use now! On one of the recent versions that I upgraded to it went from using GDAL 1.11.x to using 2.1.x. This is great, but sometimes I need to be able to write to File Geodatabases. The FileGDB driver and the ESRI FileGDB API SDK that I installed for GDAL 1.11.x no longer works under GDAL 2.1, and as far as I can tell, there is no ESRI FileGDB API SDK that is compatible with GDAL 2.1.x.

This covers the steps outlined below for those inclined to video.

Natural Earth Data #

The Natural Earth datasets are an incredible resource. If you’re a cartographer you probably already know about it, and if not, you should definitely check it out. It’s a project spearheaded by some fantastic folks affiliated with NACIS. NACIS is a great organization that does so much for the cartographic community–check them out! I use Natural Earth Data a lot so it made sense for me to get all of the data into a format where I could import/crop any dataset into my Illustrator/MAPublisher document without having to even touch a GIS.

ogr2ogr - working with file geodatabases (.gdb) #

import a .gdb into a new, blank .gdb #

ogr2ogr -progress -f "FileGDB" canvec_250K_Hydro.gdb canvec_250K_AB_Hydro.gdb

import a whole folder of .gdb’s to append to the one just created (minus the one used to create): #

for f in *.gdb; do ogr2ogr -update -append -progress canvec_250K_Hydro.gdb $f -f "FileGDB"; done;

import a single gdb into postgis #

ogr2ogr -overwrite -progress -skipfailures -f “PostgreSQL” PG:“dbname=dm106 user=jrobertson port=5432” /Users/jrobertson/data/_Generic/DM10.6/ACA_DataMaps106_base.gdb –config PG_USE_COPY YES
