How are geodatabase files loaded to Carto files?
The file geodatabase format is a collection of files inside a directory named with a .gdb extension. In order to transfer that structure around, FGDB files are first zipped up. So, any FGDB data you receive will be a zip file that unzips to a .gdb directory. FGDB data are loaded to CARTO just like any other format.
What happens when a file is imported into Carto?
When a file is imported, it is transformed into a dataset that can be processed by CARTO. The system automatically creates the following columns: This column is automatically created when overview representations of data are created (for datasets containing more than 500,000 points).
How does Carto support the shape file format?
CARTO has supported the shape file format since day 1, but we only recently added support for FGDB. We were able to support FGDB because the GDAL library we use in our import process has an open source read-only FGDB driver. Using the “open FGDB” driver allows us to use a stock build of GDAL without incorporating the proprietary Esri API libraries.
How are FGDB files loaded to Carto Directory?
In order to transfer that structure around, FGDB files are first zipped up. So, any FGDB data you receive will be a zip file that unzips to a .gdb directory. FGDB data are loaded to CARTO just like any other format.
How did file geodatabase get around MDB limitations?
The “file geodatabase” (FGDB) got around the MDB limitations by using a storage engine Esri wrote themselves. Unfortunately, the format was complex enough that they could never fully specify it and release a document on the format (and never seemed to want to). As a result, official support has only been through a proprietary binary API.
What kind of format does personal geodatabase use?
The “personal geodatabase” used the Microsoft Access MDB format as a storage layer, and stuffed geospatial information into that. Sadly, the format inherited all the limitations of MDB, which were substantial: file size, bloat, occasional corruption, and of course Windows-only platform dependencies.
How does ESRI geodatabase reader and writer work?
The Esri Geodatabase (File Geodb Open API) reader and writer modules allow FME to store data in and retrieve data from Esri’s File Geodatabase, based on the File Geodatabase API. No additional software is required to use this format, but less functionality is available than some other Esri Geodatabase formats.
