I am trying to import USGS 7.5 minute quads in .kmz format, but the files end up skewed. (in screenshot, features line up correctly along north edge, but not on east edge).
Features also seem to line up on west side but not south side.

The kmz files are from:

Specifically I'm using the Latham Spring Quad (and surround quads) in Idaho, near the ID/WY/MT boundary.
When multiple adjacent quads are displayed, they overlap (which they should not).

I know that this isn't a problem with the files because they project neatly in ArcGIS.

I have wondered if this is a problem with the datum I'm using, but I've tried changing that (NAD 27, NAD 83 CONUS, or WGS 84) and got the same result.

Any ideas?

Alternatively, does anyone have another way of getting many USGS quads imported efficiently?

It looks a little stretched, as if the northern coordinates are ok but the southern coordinates are shifted north. Did you try to open the file in Google Earth?

Yep, looks fine in G Earth.  The distortion isn't distributed equally throughout the image, so in retrospect, it doesn't look like a projection issue.

Can you share the file? You can either post it here or send me an email.

Hello,

Was there a resolution for this problem? I'm experiencing a similar issue.  Here's a screen shot of my custom map (kmz file).  No distortion when I open it in google earth.

Thanks!

Is this app still supported? I really like using it, but I haven't had luck resolving this distortion issue.

Thank you,
Michael

I'm following up on this question. This continues to be an issue for me.  I used GPS essentials for many years without encountering this problem.  Now I have a new phone and I'm seeing this type of distortion on most of my custom maps.  I haven't been able to figure out why.

Thanks for your help,
Michael
