UTM Zone Weirdness
« on: July 13, 2009, 01:25:42 AM »
I'm trying to get a handle on this UTM zone thing since I'm a user with a boundary crossing right in my local area.
For a clear example go to the following point and "color" view.
37.27080° N, 108.00391° W

Kinda FUBAR.

Can that be fixed with a change of server?

The mismatched tiles don't have to do with the zone boundary, actually.  It's just the way the server has stitched together maps from different sources.  That was the best collection of free color aerials we could find for Colorado.  You might try some other ones.  I knew of one or two others that did not cover the whole state but might possibly have better images/consistency in your area.

BTW, have you tried the alternate topo server where the maps stitch cleanly across UTM zone boundaries?

Any recommendations? I had merely been relying on the collections that TF linked to and have never looked at locating or connecting to any alternates.

I haven't.
I assume you are referring to the feature described here:
http://www.topofusion.com/forum/index.php?topic=3584.0

In fact I only became aware that there was such a capability when I did a Google search of the forums while trying to identify why I was seeing such a peculiar display.

I use topos only occasionally, mostly  to locate old trails, RR grades or 4wd roads, especially when they are not visible in aerial views.

I'm not finding an alternate CO server in my notes right now.  There is one that I'm thinking of, but I can't remember the source.  I'll make a note to look again.

Yep, that's the 'span zones' topo mode.  Could be useful if the zone trickiness annoys you.

I DID try that and discovered that it is now a simple "check box" selection rather than the more tedious configuration routine described in the December post I referenced.
Alas, it doesn't seem to change anything when viewing topos spanning the location I referenced in this thread. I even shut down and restarted TF,  but no go.
Not a big deal as far as I am concerned, but it  doesn't seem to be working as promised. 

Another glitch that I seem to be encountering regularly is that when trackpoints are selected with the "bulk" selection tool, they are not showing as  highlighted, yet the selected group moves when the cursor is used again to try to reselect the apparently unmarked points.
