Problem: Projecting Wessex Data Locks up Computer

Solution or Workaround

Description

Attempting to project data extracted from the WESSEX First Street CDs, from geographic decimal degrees to UTM (or something else), locks up the computer.

Cause

Tics with extremely large or small values. For example: tics
x,y values of -.9999000E+36 or .9999000E+36

Solution

Delete all tics with values radically outside the range of the BND file. For example:

Code:
Tables
SELECT cover.tic
RESELECT xtic > 1000 or xtic < -1000
PURGE
QUIT
BUILD cover line

Project the data again.
