10. is merely pointing to position on the scale that corresponds to the computed bearing from your location coordinates TO the target coordinates That is pure math and has nothing at all to do with which way you are facing or walking You can turn around in a circle in place and the red arrow won t move at all So please don t just try to chase it That won t work at least not just yet At this point you would just use your trusty magnetic compass to tell you which way was south and head off in that direction as best you can There is however more directional help While a GPS can t tell you which direction is which it can compute the direction you are moving by computing the bearing between successive position measurements As you recall from middle school geometry two points define a line So if you are moving iGeoCacher can compute the direction you are moving Now this gets a bit tricky because there is always some error in the GPS reading and if you ve ever used one for geocaching you know how the signal dithers about when you are at your target coordinates So to geta good sense of direction you have to require that the distance between the two points is at least on the same order as the current accuracy of the reading Fortunately this accuracy reading is available from the GPS and I display that in white on the lower right of the display with a plus minus symbol in front of it Now as shown here the accuracy position error

17. PS and you could have it all in one neat package The second generation of iGeoCacher was developed building upon what had been learned from the first and in just over a month after Apple launched the new iPhone the application appeared in the App Store on 8 24 2009 It was the first comprehensive paperless geocaching solution for the iPhone iPod Touch The early response was tremendous as geocachers with iPhones had been anxiously waiting for a solution for their platform Since then several other geocaching applications have come on the scene and a few have gone or never made it in the first place iGeoCacher continues to enjoy brisk sales and feature growth and I ve finally taken a breather to take a crack at producing a user manual Up to now the feature set has been growing at such a fast pace that a manual would be out of date in a few weeks That may still happen as the new ideas from the Yahoo group show little signs of abating Until now I ve tried to address the need for documentation with videos which can more easily be produced than print documentation However the feature and function has grown to the point that a systematic user guide is just simply required So here goes Instant gratification Quick Start Ok we ll save the gory details for later you just downloaded iGeoCacher and you want to get going The firs thing you need to do is obtain a GPX file I m going to assume that you have a file containing data in GPX format f
