Should I use File Geodatabase (*.gdb), Personal Geodatabase (*.mdb) or shapefiles? One con I'd add to shapefiles is the field name length limit. Since they use dbfs as the table storage, they're only 13 character names, which often results in names like "CALUAFID" - not very useful to someone unfamiliar with the data, and engrains bad habits in new users who aren't used to anything else. All the benefits you mention are true. I'd also like to add that the database/feature class precision can be set, so if incredibly high accuracy is important, you still can work with them, but you must be mindful |

Should I use File Geodatabase (*.gdb), Personal Geodatabase (*.mdb) or shapefiles? "Never use personal geodatabases" does a disservice, I think. It's not just reaching the data through Access, it's reaching the data through anything else that has ODBC access or drivers for using Access as a database backend. That opens up huge possibilities for serverless, spatial relational databases in ArcGIS. ESRI can do away with the mdb ones, but I think they now have personal geodatabases built into SQL Server Express, so you can do something similar. Generally, I think FGDBs are the way to go, but in the environments I work in, personal GDBs often have more utility than shapefiles. |

Hashing functions for GIS data I'll admit I'm not an expert on hashes, but in practice, people commonly rely on hashes for identification - in part because the probability of obtaining a collision is so low. A more expensive method of identification would give better results, but I think you could also use a hashing algorithm with a larger results space (SHA1, SHA256) to aid that as well. Whether or not the more complex comparison becomes fast enough vs. hashing at that point, I don't know. |

Help with Python script for exporting mxds into pdfs! Also, can you give an example of how you are calling the script? Are you using fully qualified paths? |

Tools to compare unversioned copies of geospatial data Thanks @MattWilike and Brad. This was the information I'm looking for. Of course the answer I'm looking for would end up involving the builtins. Thanks for the info on differ being discontinued. Brad, I'm mostly looking for data and feature differences, but occasionally, I'm also going to want schema differences, so that's useful |

Tools to compare unversioned copies of geospatial data Thanks for the pointer to Differ - I'll take a look at it - we're mostly using 10.0, so I hope it work! |

Tools to compare unversioned copies of geospatial data Thanks for the pointers - I'm looking for tools that help me detect changes in data that has been unversioned for about 10 years. I'll be versioning data in the future, but for now, I need to decide what data to keep from the past. |

How to make a GIS inventory? @Fetzer unless it knows how to read GIS datasets out of File and Personal Geodatabases, I'd be surprised if it would work here since there isn't a true correlation between each file and each dataset |

Two machines running the same arcpy based software - only one is leaking memory @R.K., I didn't and wasn't able to devote more time to the problem since my work projects moved away from this software for a bit - Are you experiencing the same issue? I can provide more information if it helps you diagnose a similar problem. |

How to increase the display performance of Bing basemaps in ArcMap? Very good question. This has been an annoyance of mine for a long time and makes basemaps nearly unusable, even on university and business class connections. I doubt it's anything specifically about your configuration, but I have no pointers to fix it - just hope somebody knows. |
