Incorrect Shapefile AttributeType Length
----------------------------------------
Key: GEOT-1727
URL: http://jira.codehaus.org/browse/GEOT-1727
Project: GeoTools
Issue Type: Bug
Components: data shapefile
Affects Versions: 2.4.0
Environment: Windows XP, Java 6.0
Reporter: Hari Singh Khalsa
Assignee: Jesse Eichar
Priority: Critical
Error found which sets the length of all String AttributeTypes to 254, thereby
greatly increasing the size of dbf files associated with shapefiles. This
occured when writing a new shapefile or appending to an old. More than one
append creates an invalid Shapefile as a result of this bug.
Location of ShapefileDataStore
...\gt2-2.4.0\modules\plugin\shapefile\src\main\java\org\geotools\data\shapefile
Location of Bug: Class: ShapefileDataStore; Function: createDbaseHeader; Line:
1090
Description: AttributeTypes with filters that restrict length do not pass this
if test and therefore are set to the default lengths. This is mostly a
problem for String attributes, which get set to a default length of 254.
Work around: Copy ShapefileDataStore into local package. Modify lines
1090-1092 to allow attribute types with length filters to pass through. Change
package. Add org.geotools.data.shapefile.Lock to the import statements.
Utilized this modified ShapefileDataStore.
