This is a very powerful map tool which lets you accurately measure distances, remember locations, get magnetic headings between selected points and much more. GPS WIZ is a powerful navigation and measurement tool that uses GPS maps in a variety of ways. Pan and zoom on the map to locate and display your coordinates in both decimal degrees and degree minute second formats. Save selected locations in permanent memory using a Site List with your own specified name for each site. Display these sites anytime by selecting them. Add control zones for your airport entries and they will automatically display on the map for the area you choose to view. Airport zones are color coded for UniCom, Mandatory Frequency (MF) and Class-C zones. Create and save trips which specify unique routes with your own waypoints in a Route List, either directly from the map or selected from your saved sites. Display your route on the map with a pin located at each waypoint entry. The map is auto scaled to fit the full trip onto your screen. Touch the pin to identify that point. The total route distance will be calculated and shown automatically but you also have the ability to measure each leg distance and leg heading (in degrees magnetic) by simply pressing the Leg button. This is useful for pilots to estimate fuel requirements or for hikers to estimate walking times between waypoints. True bearing is calculated from spherical geometry using latitudes and longitudes. The World Magnetic Model (WMM) is used to calculate magnetic declination and magnetic bearing and any point. A pin drop feature lets you measure distances from your current location to where you drop pin 1 and the distance between pin 1 and pin 2 so you can measure interesting map features quite accurately. This is a powerful feature for pilots to determine takeoff and landing distances on remote airports, grass strips and lakes for floatplanes. Moving the map automatically draws a line from your current position to the centre of the target. Both distance and magnetic bearing are displayed. By placing the target on any point of interest, you automatically get a distance and bearing to that point from your current location. Placing pin 1 on a point of interest (e.g. airport) then moving the map to another point of interest (e.g. another airport) gives you the distance and bearing between these points. This feature is very helpful when estimating destinations or finding your way out of a forest, or even a large crowded mall. A wide variety of users from builders, architects, pilots and boaters to crane operators will find this feature very useful. There is no annoying advertizing. The APP is full featured so no costly upgrades are required. Have fun with it. There is also a built-in Guide available to provide instructions on how to use the various features. The 2015 World Magnetic Model is a joint product of the United States National Geospatial-Intelligence Agency (NGA) and the United Kingdomβs Defence Geographic Centre (DGC). The WMM was developed jointly by the National Geophysical Data Center (NGDC, Boulder CO, USA) and the British Geological Survey (BGS, Edinburgh, Scotland).
