USA backcountry hike from Mount Madonna to Loma Prieta involving 2
topographic geoPDF quadrangles and iOS/Android plus GPX tracks & waypoints

a. We need a free ad free iOS/Android app to show our position on the map.
b. We need reliably accurate 1:24K or better geospatial geoPDF maps.
c. We need to stitch geoPDFs together & we need to add tracks & waypoints.

This is the first process I came up with to help a group of high school kids
navigate a backcountry hike from Mount Madonna to Loma Prieta without
following trails (where the kids are on both iOS and Android).

The goals are to provide them with a process that they can navigate on the
phone under the common conditions that the phone has to be self sufficient.

Here's the first process I came up with but I ask for improvements from all.

1. Install Avenza Maps <https://www.avenzamaps.com/mobile-maps>
   Android: <https://play.google.com/store/apps/details?id=com.Avenza>
   iOS App: <https://apps.apple.com/app/apple-store/id388424049>
2. Obtain a geospatial PDF (with or without your desired waypoints & tracks)
   (see one method below)
3. Load those GeoPDFs into Avenza (using the yellow "plus" button)
   That's it. When the kids hike, their position shows up on the geoPDF.

When the kids hike, their position shows up on the geoPDF on their phones.
When they move out of one quadrangle, they can switch quadrangles.
It's not pretty. It doesn't have tracks. Nor waypoints. But it works.

They can even add a GPX track of where they've been onto the existing maps.
Here's the process I used to obtain the specific geoPDFs from the USGS.

1. Go to the USGS Store "Map Locator" to find the quadrangle to download.
   <https://store.usgs.gov/map-locator>
   And search for the quadrangle of interest.
   For example, I searched for:
   a. Mount Madonna
   b. Loma Prieta

2. On each desire quadrangle perform this process to obtain the geoPDFs.
   a. Doubleclick on the middle of the desired quadrangle
   b. That will insert blue teardrop & show a blue "View Products" button
   c. Press the "View Products" button to obtain the desired geoPDF

3. "View Products" will provide a long list of current & historical maps.
   
   For Mount Madonna, I chose the following 2018 topographic map.
   MOUNT MADONNA, CA TNM GEOSPATIAL PDF 7.5
   <https://store.usgs.gov/product/496218>
   <https://prd-tnm.s3.amazonaws.com/StagedProducts/Maps/USTopo/PDF/CA/CA_Mount_Madonna_20180905_TM_geo.pdf>
   Name: CA_Mount_Madonna_20180905_TM_geo.pdf
   Size: 64360685 bytes (61 MiB)
   SHA256: 8AD221503568F28F534E28767681CC7326E88C0B26058DB86870F8B9063D8289

   For Loma Prieta I chose the following 2018 topographic map.
   LOMA PRIETA, CA TNM GEOSPATIAL PDF 7.5X7
   <https://store.usgs.gov/product/494076>
   <https://prd-tnm.s3.amazonaws.com/StagedProducts/Maps/USTopo/PDF/CA/CA_Loma_Prieta_20180905_TM_geo.pdf>
   Name: CA_Loma_Prieta_20180905_TM_geo.pdf
   Size: 67062849 bytes (63 MiB)
   SHA256: 4C822EB88CC2799288A0BF9BE41D884FA0CB05861BC1AF9EA93DE432E8ED075A

At this point each kid can load the maps above into his iOS/Adroid phone
and Avenza will show his current position on those geospatial PDF maps.

This works, but the process can be improved by a lot.

We need a few things that others who know more than I do can help with.
A. Is there any other Android/iOS free app that works as well or better?
B. How can we most easily stitch the maps together into a single map?
C. How can we most easily add desired waypoints & desired gpx tracks?
-- 
The goal is a completely free but simple method for kids to download and use
backcountry topographic maps on their phone for accurate crosscountry hikes.
