GeoExpress cannot read world file

Issue

When you use GeoExpress to create a world file, you may find that the resulting MrSID world file (.sdw) can not be read by GeoExpress (even with world file support enabled). This happens because some languages use a comma as a decimal separator while others use a point. GeoExpress only recognizes the point. Your file may contain commas instead of decimal points.

Given the original .tfw file…

1.000000

0.000000

0.000000

-1.000000

3390118.500000

5723245.500000

…GeoExpress produces the following *.sdw file:

1,000000000000000

0,000000000000000

0,000000000000000

-1,000000000000000

0,000000000000000

5871,000000000000000

Solution:

Change the settings for “Regional and Language Options” in the Control Panel of your computer. The decimal symbol should be a “.” (point), and the digit grouping symbol should be blank or “123,456,789″.
