【實用交通運輸app】GPS WIZ|最夯免費app-綠色工廠好玩App

GPS WIZ is a 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. You can also enter specific coordinates in either format and go directly there. Save selected locations in permanent memory using a Site Table with your own specified name for each site. Display these sites anytime by selecting them. Create routes with your own waypoints in a Route table, either directly from the map or selected from your saved sites, also with custom names if desired. Display your route on the map with a pin located at each waypoint entry. The map is auto scaled to fit the full route 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 true and 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. 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. A wide variety of users from builders, architects, pilots and boaters to crane operators will find this feature very useful. There are a lot of tools available for the price of a good cup of coffee and a cookie. 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 World Magnetic Model is a joint product of the United States’ National Geospatial-Intelligence Agency (NGA) and the United Kingdom’s 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).
