Maps have compressed aspect ratio
« on: June 26, 2012, 05:12:53 PM »
The platform is Windows 7 on a Core I7 laptop with sufficient RAM, graphics, etc.  I've used TopoFusion for a number of years now as my GPS interface, track library, track editor, etc.  Nice tool.  After upgrading to TopoFusion 4.50, I noticed that all the maps were compressed vertically, such that square objects (section lines, for example) are shown as rectangles.

Here's a screen shot of the problem:



Here's an image of the same area from an old map:



I don't see anywhere to adjust the vertical or horizontal aspect ratio of displayed maps.

Is this some new "feature", reflecting my relatively far-north latitude of 64 degrees? (I'm in Fairbanks, Alaska).

Just to be sure, I deleted the topofusion.ini file and restarted TF, with the same results.

Is this correctable, or is this the new normal?

EDIT: I've now upgraded to TF v4.60.  Same vertical compression for all maps except B/W Aerial, which has a natural 1:1 aspect ratio.  I thought that I'd try Topo (Old), but it doesn't even try to load.  Whatever map is currently loaded just stays in the viewport, and there is no sign of attempting to switch to Topo (Old).

Well, I haven't gotten any replies, so I searched around in my "Downloads" folder, and found version 4.31.  Uninstalled version 4.60, installed 4.31, and that sort of fixed the problem.  At least when I select "Switch to Topo" from the Map pull-down, I get a correctly displayed topo map.  Selecting the "Switch to MyTopo" still shows the really squished view.

Guess I'm stuck at version 4.31....  sigh.

Hey aksnowbiker,

It's a product of your high latitude.  Not intentional, just a byproduct of the way TF displays the map.  I don't think a previous version would change it, unless we had released a funky one time version in mercator mode?  I don't think so.

With as many google maps tile style mapsets as we have (and are likely to add) I plan to change to that native projection, so in a future version hopefully the 'extreme' latitudes won't suffer from such distortion.

Sorry about the issue... and late response.
