What kind of private land details do you share?
Our private land ownership details including the exact land boundaries and address, assessor's parcel number (APN), and the owner's name.
Do you use USGS topo maps?
Yes. Each memory card comes with full-color USGS topographical maps in 15 zoom levels (1:250K to 1:24K) and 3 super-zoom levels. These topo maps are also scanned, enhanced, and updated by our sister company, MyTopo. In addition to base topo maps, each memory card includes extra map overlays where available. The extra overlays can include public land boundaries, forest roads, hunt units, and lake maps with underwater depth contours. Check out the specific state pages for more details on map coverage.
Can I record tracks and mark waypoints while using the SD cards?
Yes. Our navigation app (GPS Hunt) works seamlessly with the Topo Maps SD Cards to turn your smartphone into a full-fledged GPS unit that works in remote places without a cell or data connection. Launch the app to view statewide topo maps, see private land boundaries, record tracks, mark waypoints, and take photos and videos.
The memory cards also work with our fishing app for iPhone and Android called Trimble GPS Fish. They also work with our trip planning iPad app, Trimble GPS Maps.
How much of my device's internal memory will be used?
Android: Hardly any. All of the maps are stored on the SD card, so you don't have to give up precious internal device memory to store and view maps. We also leave extra space on each memory card, so you can store your own apps, photos, etc. on the SD/microSD card.
iPhone/iPad: As much or as little as you want. You can handpick what maps you want stored on your iPhone or iPad. For instance, if you are hunting in Adams County, only drop the Adams County maps onto your iPhone or iPad. Most iPhones or iPads don't have enough internal space to store an entire state's worth of topo maps and private lands. For example, the state of Utah is 10 gigs of maps. That's a lot. That's why we allow you to pick-and-choose the maps you need and drop them into your iTunes account.
