For "Topo Nomad" and "Topo Reader" apps: nps-footprints.tnez Adds the Nation Park Service map footprint indexes to these two apps. Download the nps-footprints.tnez file on your iOS device using Safari and select "Open in..." or "More" option and select "Copy to Topo Nomad" or "Copy to Topo Reader" app. If sent as an email attachment, don't tap the icon, instead press and hold on the attachment icon until the table of apps appears and select "Copy to Topo Nomad" or "Copy to Topo Reader". Do NOT run on the "NP Maps" apps. These footprints already exist in the NP Maps apps and openning this may cause redundancy in with footprints (untested and although probably harmless, it would require deleting and reinstalling that app to repair any issues).
