VECTOR CHARTS The National Oceanic & Atmospheric Administration provides both RNC (raster) and ENC (vector) charts. http://www.nauticalcharts.noaa.gov/mcd/learn_diffRNC_ENC.html The great advantage of the RNC charts used by iSailGPS is the high level of detail produced by professional cartographers that is unobtainable on any vector-based chart. NOAA produces a digital image of each paper chart. These RNC Charts differ from computer-drawn vector charts in that each chart covers a specific area, the same way a paper nautical chart does. A new chart is switched to when traveling out of the area covered by the previous chart. For most locations, there are multiple charts at different scales with different levels of detail & areas of coverage. Paper charts can contain multiple panels, each showing a different area or scale. Each digital panel is individually displayed by iSailGPS with a north-up orientation. Other, more expensive marine software, uses these same RNC charts. iSailGPS is priced to make it readily available to all sailors. DEVICE REQUIREMENTS No device requires a cellular data plan to use iSailGPS iPhone 4 or later & all WiFi+cellular iPads support full navigation iPod touch (Gen 3 or later) & WiFi-only iPads require an iOS-compatible external GPS receiver to show your location & record tracks. View charts using the iOS device alone File sharing via AirDrop & Messages requires iOS 7 or later Continued use of GPS running in the background can dramatically decrease battery life Winner of the Practical Sailor 2012 "Editors' Choice Award" Sailing becomes safer and more fun with iSailGPS!
