Planning to travel within the USA on your next wilderness adventure? Dont leave home without the proper map application for your iOS device!

Introducing TopoPointUSA, a wilderness navigation tool for viewing FREE United States Geological Survey (USGS) topographic map images and your GPS position whether you are online or not!

◆"Pinch and Zoom" now supported!

USGS topographic maps contain the highest detail of any map suitable for wilderness travel within the United States. TopopointUSA downloads these maps from a USGS server and stores them on your iPhone.

◆TopoPointUSA v2.9 delivers essential features in a lightweight (3.2MB) package:

◆Multiple map scale support: 1:250k, 1:100k, 1:24k USGS map support for the entire continental United States and all parts of Hawaii! 1:250k, 1:100k, and 1:63k for Alaska!

◆Compass displays true or magnetic north!

◆Online "browse to location" feature displays arial and street map data when downloading maps or browsing to a location.

◆Robust scrolling main map view that moves seamlessly across quad boundaries.
As your GPS position changes the map will automatically track in the direction you are traveling. "Swipe" scrolling away from your current location invokes browse mode. Pressing the locate button resumes tracking of your current GPS position. Coordinates are displayed in decimal degrees format.

◆No Service? No Problem!
Simply download maps of your choice directly to TopoPointUSAs Map Case before departing the cellular data service area or WiFi connection. Your maps will be available anywhere! The map name is chosen by the user and displayed on the main screen when in use. To browse a saved map in the main screen, just select it in the map list and return to the main TopoPointUSA screen.

◆TopoPointUSA gives the user control over downloaded map sizes and boundaries.
By specifying downloaded map location and size, the user has control over how much data will be stored. After downloading, maps can be browsed in the main screen to ensure the correct data is onboard.

◆Automatic offline or online operation
When located within a cellular data service area or connected to WiFi, TopoPointUSA will automatically download and display map images for your current or browse location. When offline, TopoPointUSA will automatically display stored maps in the main screen. When in locate mode, the GPS position indicator will automatically display your position on saved maps in the main screen.

◆Main screen display of GPS Position with accuracy and map scale information.
TopoPointUSA features an innovative GPS position indicator with integrated radial map scale and GPS accuracy information. Scale and GPS altitude can be displayed in English or Metric units.

◆Powerful Browsing capabilities with position display.
TopoPointUSA also includes advanced browsing capabilities. Detailed Latitude and Longitude coordinates are displayed when browsing map images away from your current location. A precise browse position indicator with map scale is also displayed when browsing.

◆Fully featured Waypoint capabilities, including "Tracks" (T button).
TopoPointUSA creates Waypoints with a single main screen button press. Current GPS location or browse location is recorded by simply tapping the coordinate display text button in the bottom toolbar. Waypoints can also be entered manually. UTM coordinate and creation time are also recorded for each Waypoint. GPS altitude is recorded for Waypoints created with GPS position. Waypoints are stored in user definable Waypoint Sets and can be emailed via the iPhones mail application.

◆GPS course and speeds displayed on an optional overlay popup by pressing the M / Motion button.

◆Online USGS geographic feature search.
