Looking for someone to provide the distance calculation formula and implementation between 2 GPS coordinates. The code ideally should be able to provide distance calculations not only between 2 points with coordinates but between a polygon shape and a gps coordinate. A bonus would be to set a flag to check for specific distance apart, and if that flag is triggered, the state of a variable is changed.

I am very proficient in c and c++. I have 16 years c++ developing experience now, and have worked for more than 6 years. My work is online game developing, and mainly focus on server side, using c++ under linux environment. I used c++ to make many great projects, for example, I made the tools which can convert java files into c++ scripts, of course garbage collection included, this job is very similar to a compiler, and is very complex. I also made our own mobile game using c++, I can show you the demo of client, if you like. I am very proficient in java also. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you.

Hello, Could you please let me know if you need a C++ code? Would it provide a distance between 2 points on the map by road or simply the 'direct' distance? Thank you, Sergey.

Hi there! I'm a perfect candidate for your project! I've been working in UK as a software developer for drone ground control stations for 2 years now. The main feature of the programs I'm working on is placing waypoints on the map, calculating distances between them, moving them around etc. When calculating the distance between a polygon and a waypoint would you like to calculate the distance between the geometric centre of the polygon and the other coordinate? To keep your implementation clean I would propose that I deliver you couple of functions (calculating distance between coordinates, distance between polygon and gps coordinate, distance between two polygons?). Given my experience with handling gps data you can be sure that you will receive your solution on time and that it will be done correctly. Best regards, Mateusz Sadowski

it's a simple project. the formula is simple : a = sin²(Δφ/2) + cos φ1 ⋅ cos φ2 ⋅ sin²(Δλ/2) c = 2 ⋅ atan2( √a, √(1−a) ) d = R ⋅ c where φ is latitude, λ is longitude, R is earth’s radius it will be a simple program and I can output the distance in meters, kilometer, miles .. etc. the part about the polygon shape is also simple, I can easily calculate the center of the sample and get the distance from there and there are many other ideas. The flag part is simple and can be added using one statement. I can provide sample for this project before we start working. I have experience of years in C++ programming and I can do the job in minimum time and give you a well documented project.

Dear Sirs, I believe that I am a good match for this project as I have many years of experience writing software around GPS based applications, and am very familiar with developing code such as you have described. I have previously written functions in C to calculate the distance between two latitude/longitude pairs. I have also previously written code similar to your polygon problem. Your bonus problem seems like a fairly easy add it, after the first two parts of your project are completed. I am confident that I can develop and test the simple distance calculator in 4 hours. The polygon distance calculator is more involved, but I am confident that I can develop and test that in less than 8 hours (and I am willing to cap my effort at that level as well). The bonus should require less than one hour to develop and test. I trust that this meets your needs. If you have any questions, please don't hesitate to contact me, Sincerely, Brian Lelacheur
