The most important thing to do in Topo Maps+ to get ready to “leave the grid” is downloading maps. When you download maps you can access those maps on your iPhone without needing an internet connection. Version 2.1 added a much easier way to download USGS and Thunderforest topo maps.
When you want to download maps first zoom and pan the map to the area you are interested in downloading. Then select “Download Maps” -> “Download Map Regions” in the app.
This will show you the map with a grid overlay on top of it. Tap on the regions you want to download and then tap on the download button in the upper right corner.
Before heading out the door be sure and check that you have the maps you need downloaded. There are two ways you can check which maps have downloaded. You can go back to the download map regions. This will show you which maps have been downloaded.
You can also go to the “Downloaded Maps” section. This will list out each of the regions you have downloaded. You can tap on any of them to go to that location in the map.
There is one other way to download maps that works for all map types and not just for USGS and Thunderforest topo maps. You can turn on turn on download tiles. Turning on this setting will make Topo Maps+ save all map tiles that it downloads. As you scroll and zoom around on the map all map images that you see are downloaded and saved. This only saves the images you are looking at and not the region at different zoom levels.
