Gridding Right to Left, Bottom to Top

Roger Edrinn

First time around, I gridded my export from top-left to bottom-right. Because my maps are in North America, the opposite: bottom-right to top-left would actually be more natural. That way the row-column suffix would increase numerically as does the lat and long.

I'm exporting 1 x 1 deg extents into a 4 x 4 array or 16 - 15' quads. I'd like the bottom-right segment to be A1 and the top-left to be D4.

The mp vector export dialog has a reverse switch, can that help me? What settings would work in the dialog? Do I start at D4 and use a -1 increment?

Thanks

If you just check the 'Reverse' check box you don't need to change the start or step values, they will automatically start with what you want at the right and bottom as you want.

Let me know if I can be of further assistance.

Oh so elegant.

Because you actually grid top-left to bottom-right, but in reverse naming order, D4 to A1 in my example. The ID number is no longer in minor to major order implied by the reverse gridding.

When you compile the MP files to img, all those files are now out of order, because they assume the 8-digit ID for their file name. Gridding in true reverse order, bottom-right to top-left, would solve this.

Is their a solution?

I suppose if you have checked both reverse options I could reverse the actual list of grid cells that are exported. Would this work?

I did check both reverse boxes, best I can tell, the A1 - D4 are in the correct geographic order. So my only problem is that the ID starts at D4 and then increments along D. Such that D4=ID, D3=ID+1, D2=ID+2, D1=ID+3.

So given the above, if A1=ID and D4=ID+15, when I'm gridding bottom-right to top-left, I'd be "fat, dumb and happy".

I tried using the ID in the template file but it didn't increment. So I went back to your April 13th email where you show me how to change the last ID in regedit, worked fine.

Thanks

Roger,

I've gone ahead and made the export order be reversed if both reverse options are checked. I have placed a new build at http://www.globalmapper.com/global_mapper9.zip with the change for you to try. Simply download that file and extract the contents into your existing v9.xx installation folder to give it a try.

Let me know if I can be of further assistance.

Thanks Mike!!!

I'm "fat, dumb and happy".

I really didn't want to lose the logical order, I'll be doing all my maps in this B-R to T-L logical order from now on.
