A New York township recently had several thousand old property record cards scanned to reduce paper clutter in their office.  In New York State each property has what is called a tax map number.  The tax map numbers were not written on the cards in the proper format and the company which scanned the cards tried to do the best they can to name the files appropriately.  We stepped in to write a program which determined the correct tax map number by cross-referencing the filename with the town's property database.  After the files were matched up, they were then renamed, copied to the main image store, and the town's database was updated with a pointer to the image.
