$95-100 USD

Paid on delivery
I am a .net developer, and I would like someone to help me build my gps application. Bonus payment of $100 will given if the code works well and is done in a quick time. FORM A: 1)? It currently counts down like a Drag Car Race Lights... 2)? It will detect the GPS co-ordinates moving forward, and calculate, 1/4 mile, 60ft time, Speed,? etc. 3)? 90% coding already done, just needs someone to check that the ideas and code is implemented sensibly. FORM? B:? 1)? translate the GPS longitude and Latitude co-ordinates into a ScreenpixelX and? ScreenpixelY for the cursor display. (already done, but it needs to resize the race track loop? on the screen automatically) 480x272 resolution. i.e if its wider than it is tall, or if the track is taller than it is wide the scale must calculate correctly to fit the correct scale. 2)? Create a LapTimer class that records a collection of lap times when the? GPS position passes through a known GPS segment line (start/finish line)? this will be done with a function I already found that can tell if two lines intersect, i.e pointA-B (start finish line)? has intersected with? point C to point D (gps travel line) ## Deliverables The drag one is easy because its straight line, it is practically already programmed and done. The lap timer is more interesting, imagine this scenario... 1) the driver drives his car slowly around the racetrack loop, the gps raises events every 1 second. 2) the driver when crossing the start finish line presses the "set start/finish line" form button (programming code must calculate the position the car is currently (based off the previous gps point, and the next gps point) and in the program memory, it must store a perpendicular segment line 14 meters wide. 3) the driver then can set up to 4 more segment lines (sector points) as he drives around the course. 4) Then the driver starts racing, when his car goes past a segment line that was stored by the program (i.e start/finish line) then the code must know the time between the last segment line (sector) To determine if the car just past a segment line, every time a gps point event is raised every 1 second, you can compare the gps point now, and the previous gps point to create a segment, and then compare this segment with all of the stored sector segment lines (including the start/finish segment line) if any of the stored segments intersect with the current driving segment line, then we know that the car just drove over a stored segment line. i have the code that compares two segments and returns boolean true if the segements intersect each other. (this function uses integers, not gps points, so you must convert the gps latitude and longitude to pixels(i.e. decimals or integers). The geoframeworks dll that I'm using, already has a position object that has a method to scale the worlds longitude and latitude system down to the pixels for the 480x272 pixel screen.) so you can represent the segments in terms of pixels on the screen if you like. although 480x272 resolution may be too scaled down to be accurate. perhaps it is better to use an intermediate scale for determining seconds/milliseconds between sectors. yes inaccuracy will be inherent with 1 sec gps events. for now I just wish to stick with non acceleration based calulations, just Time linear calculations between two points to determine setting a sector point and/or where the vehicle may have cross over the segment line. examples of the gps dll position events raised every 1 second.
