Known two projective coordinates of points and a projection coordinates of latitude and longitude coordinates of points, according to the relative relations of projective coordinates calculation such as distance, Angle, calculated another projection point of the latitude and longitude, for help

First top don't sink

CodePudding user response:

Don't calculate, direct IGeomety. Project () shall be able to find

Known (x, y)=f (l, w, x, y? Math is not reasonable,
And this algorithm also need not oneself study, study,,
Baidu the projection coordinate geographic coordinates, what mathematicians study for hundreds of years already very mature,
If as long as the results have a lot of coordinate transformation of small tools, the precision is also guaranteed

CodePudding user response:

What you said is the coordinates of latitude and longitude, the Internet a lot of
You first determine what are the coordinates of then you want to what kind of latitude and longitude

You'll have to give the coordinate system, you have to know a very simple fact, is the ground floor plan is not to find the latitude and longitude, the plan because the ground is flat surface, so the latitude and longitude conversion is needed a second calculation, using Angle distance of points and plan can't overlap,
