I started making these maps for my own use when I was unable to find maps that suited my needs for hiking. The USGS 7.5 minute quadrangle maps (“quads”) I had used for years are dated and don’t show current conditions. New trails have been constructed, old trails have been re-routed, etc. The current “US Topo” maps often don’t even show hiking trails. And other custom map vendors seem to focus on the popular National Parks not the local and regional county, state and forest areas I do most of my hiking in.
Once I started making and using my own maps others I hike with and other trail maintenance volunteers asked for copies. This led me to think there might be some demand for these maps.

My maps are aligned to grid north. On these maps the difference between grid north and true north is less than the usual error in using an orienting style compass. The legend at the bottom of the map gives the difference between grid, true and magnetic north on each map.
And I’ve notice that many (most?) paper map users are using UTM grid lines without compensating for the difference between grid north and true north. So having the map aligned to true north does not seem to be required by most map users.
Data for Tod’s Topos comes several sources:
The OpenStreetMap project is basically the Wikipedia of map data: It is largely maintained by volunteers (though large companies like Amazon Logistics and Lyft use it and pay mappers to help improve road data in it).
There appears to be a sufficient number of hikers, mountain bikers and equestrians who are OpenStreetMap editors that the trail data in OpenStreetMap is usually the best available. Licensing makes it very attractive too: You simply need to acknowledge the OpenStreetMap contributors. It seems that other hiking apps like Gaia and AllTrails use OpenStreetMap as well.
Maps are usually for areas I have hiked in since I started using the Avenza Maps app. Or they are for areas I am considering hiking in.
More to the point, they are generally areas that I have done volunteer mapping for OpenStreetMap so I have some confidence that the trails are reasonably well mapped.
If you would like a map for some other area(s), the bounds (latitude, longitude), scale and name(s) for map(s) you would like to have created and I will add them to the build list and inventory.
Any such new maps would be in areas that I haven’t recently hiked, so I would be relying on the requestor to assist in keeping the OpenStreetMap data for the map areas up to date.
No. Not even close in some cases. Or it has been so long that things might have changed. But I have hiked a lot of them and in a number of cases have worked on trail maintenance projects.
I have had a request to render the trails I’ve mapped differently trails than mapped by others. The work flow for doing this is not feasible at this time.
As noted above, data is largely from OpenStreetMap. If you find an error on a map you can fix it by fixing the data in OpenStreetMap. Accounts are free and there are tutorials for how to get started on editing.
If you don’t wish to edit the OpenStreetMap data, then please upload your GPS tracks to the OpenStreetMap website. In addition, upload geo-referenced photos of items that are missing to projects like Mapillary. Mapillary allows photos it hosts to be used for mapping in OpenStreetMap. By uploading your tracks and photos the next map editor that tries to correct the trails has better data to work with
Finally, if the above is too difficult then information about the things that need fixing and I will try to work with you to correct the data.
For myself, I usually review the map before going to an area and then while hiking I make notes about how the map can be improved. Once back home I edit the OpenStreetMap data. The next time Tod’s Topos are generated the fix will be in them.
I have written a number of scripts and programs to create geo-referenced PDFs. The workflow has evolved and is more complicated than it seems it should be. You can read about some of the things I had to deal with:
They are available on the Avenza Map store.
Maybe. I have found a local printer capable of printing these large PDFs onto 20 pound paper stock however the cost may not make it attractive. If interested please
