Working with rasters in file geodatabase (.gdb) with GDAL

Question

I'm working on a tool that converts raster layers to arrays for processing with NumPy, and ideally I would like to be able to work with rasters that come packaged in a .gdb without exporting them all (especially if this requires engaging ArcGIS or ArcPy).

Is this possible with the OpenFileGDB driver? From what I can tell this driver seems to treat raster layers the same as vector layers, which gives you access to some data about the layer but doesn't give you the ReadAsArray functionality.

Answer 1

Currently both FileGDB and OpenFileGDB drivers handle only vector datasets. Raster support is not part of Esri's FGDB API.

You will need to use Esri tools to export the rasters to another format, such as GeoTIFF.

Answer 2

我刚刚发布了原型程序Arc Raster Rescue ，该程序可从ArcGIS File Geodatabase格式提取栅格数据。
