FileGDB Compression is Not Installed Error

MichaelChilds

A customer has provided a GDB with a single FeatureClass, but when we try and open the table we get a "FileGDB compression is not installed." error from the FileGDBAPI::Geodatabase::OpenTable call. Is there some way to open these files or install the FileGDB compression that Open Table is looking for? I can provide the GDB if needed.

Thanks,

Mike

Hi @LanceShipman , when will the SDC Smart Data Compression support be added to the File Geodatabase API?

LanceShipman

We added support for reading compressed file geodatabase data at version 1.4 of the File Geodatabase API. The current version of the API can be found at file-geodatabase-api/FileGDB_API_1.5.1 at master · Esri/file-geodatabase-api · GitHub.

Dear Lance Shipman,

have you got any news about the compressed data support for FileGDB?

There is a .gdbtable.sdc file in the folder, so it appears to be compressed. Is using compression something that is pretty common?

Thanks,

Do you have ArcGIS? If so, open ArcCatalog. The feature class should be flagged as "Compressed". If you don't have ArcGIS, look under the file geodatabase folder for files with a .gdbtable.sdc extension. If you find any tables with this extension, at least some of the data is compressed. If we can not determine if the data is compressed by either of these methods you can copy the zip file to the esri ftp site.

I believe the data is not created by the client but something published by some government agency so it would likely be problematic to get them to uncompress it. Are there plans to support compressed data sets or to at least instruct users not to compress their data if they want it usable in a large number of products?

I would attach the file but it seems there is just a 2MB limit for .zip file and this file is a bit over 9MB. Can that limit be increased?

Thanks,

Mike

The API does not support compressed file geodatabase data, so you will need to get your customer to uncompressed it before they send it. Please provide the GDB (lshipman@esri.com). I'd like to examine it to make sure that this is compressed data and that we are not returning the wrong error.
