Thank You OZ.
Taken directly from your tutorial, it appears I am supposed to edit two lines of the batch file:
I did eventually get this to work with only editing one line (the first).
Taken directly from your tutorial, it appears I am supposed to edit two lines of the batch file:
QuoteCombine All The Contours Together
1. First we will combine all the contours into one file. We have created a batch file that you can run and it will use FWTools to combine the contours. Download the bat file here and extract it.
2. Edit the bat file in Notepad (right click and click "Edit")
3. On the first line change the folder to be the folder where you have all the folders containing the contour lines folders.
4. On the second line set your location to the FWTools bin folder (the default for 2.4.7 on a 64-bit OS is already set)
5. Save the file
6. Now double click on the bat file to combine all the contours together. Note: Currently FWTools will crash if the file gets over 4gb; if this occurs you must split your contours into two separate folders and combine each half of the state separately. For reference: for Arizona the file was only 3gb.
7. A new file has been created called "mergedcontours.shp"
