John Thorn USA state topos cause problems

Buzz Boykin shared this question 11 days ago

After selecting John Thorn topo for Virginia USA then reselecting LoMap for Virginia it no longer works properly.

The streets are scaled far too large and moving around map gives loading messages on map segments. Uninstalling/reinstalling Locus Maps Pro is the only way I have found to get Virginia LoMap to work properly again.

Dear Buzz,

would you please try to change back to the any default internal theme (eq. Hike & Bike) when you re-select LoMap Virginia map?

Please let me know about progress.

Best regards



That fixed my problems. Many thanks for the quick help.

Great app, wish you could add support for geopdf. Only source here in USA are higher priced subscription services.

Again, many thanks.

thank you for info, I'm glad that's "fixed"... We'll improve the app to select automatically the internal theme when user re-select LoMap map.

Regarding geopdf - I'm sorry but support for geopdf isn't planned at this moment. Could I ask you what data / map you'd like to import as geopdf or ahat is source for these geopdf files.

Thanks, Petr


The geopdf maps I am interested in are U. S. Forest Service Topos.  The regular USGS topos that I can get into Locus Maps are good, but most of my camping/hiking/biking is in National Forest and their topos have better trail, forest service road and shelter info than the USGS ones. Avenza maps works with them but is subscription based at 30 USD per year. It's nice, but not worth that compared to Locus with the USGS topos. I would get Neotreks from you before paying Avenza. I use your Neotreks for Shenandoah National Park and it is good. Thanks again.
