Summary
Shapefile Repair Tool Beta4, 04 Jan 2006

Shapefile Repair Tool is a .NET Windows application that fixes damaged
shape files (SHP and DBF).

- SHP and DBF files are read and validated, (indexes are ignored).
- Null Shapes are retained (usually valid deleted records)
- Misnumbered and out of sequence SHP records are fixed.
- Invalid shape types are corrected (e.g. point type in a polygon SHP file).
- DBF record count mismatch is corrected by either padding the DBF file or
  truncating extrainious records.
- A new shape file is written. Geometry is NOT altered.
- Database contents are not altered other than checking for valid data.
- A log file is written to document the changes

Shapefile Repair Tool is a standalone Windows application now in beta testing.
Please send us your broken shape files so that I can improve this application
(and perhaps repair your data files).

The zip file contains the application in a windows installer (MSI). To install
download and unzip the files from the zip archive and run setup.exe.

Note: Microsoft DotNet 1.1 is required.
