Shape file header description

Shape file header description

Post by mfh at wor » Sat, 06 Jan 2001 01:20:18

according to ESRI shapefile technical description document, the main
file header looks like the following:

Byte Position    Field             Value     Type         Order
Byte 0              File Code      9994     Integer       Big

What is the meaning of the Value 9994 field, is there any other
alternatives ?
I encountered a shape file with a 9997 value in this field what could
that be ?

thanks for your help
