wgs84

Searching for some sample code for converting a point in WGS84 coordinate system to a map position in Google Maps (pixel position), also supporting zoom levels. If the codes is well commented, then it can also be in some other language. You can also point me to a open source Java project :) Some resources found: OpenLayer implementation. JOSM project Excellent Java Map Projection Library from JH LABS. This is a pure java PROJ.4 port. Does projection from WGS84 to meters. From there it's quite straightforward to convert meters to tile pixels. andyuk Tile utility code in Java on mapki.com (great

I have a velocity vector in altitude, longitude, altitude, I would like to convert it to Cartesian coordinates, vx,vy,vz. The format is from WGS84 standard. here is the formula //------------------------------------------------------------------------------ template <class T> TVectorXYZ<T> WGS84::ToCartesian(T latitude, T longitude, T elevation) //------------------------------------------------------------------------------ { double sinlat, coslat; double sinlon, coslon; sincos_degree(latitude, sinlat, coslat); sincos_degree(longitude, sinlon, coslon); const double v = a / sqrt(1 - WGS84::ee

[Complete re-edit by Spektre] based on comments I have two start points and velocity vectors in 3D (WGS84) how would I check if they are colliding in 3D within some specified time? Sample input: // WGS84 objects positions const double deg=M_PI/180.0; double pos0[3]={17.76 *deg,48.780 *deg,6054.0}; // lon[rad],lat[rad],alt[m] double pos1[3]={17.956532816382374*deg,48.768667387202690*deg,3840.0}; // lon[rad],lat[rad],alt[m] // WGS84 speeds in [km/h] not in [deg/sec]!!! double vel0[3]={- 29.346910862289782, 44.526061886823861,0.0}; // [km/h] lon,lat,alt double vel1[3]={- 44.7 ,-188.0 ,0.0}; //
