| #125020 | Can I use this software to convert UTM coordinates? |
| The GPS Toolkit offers functionality to convert coordinates to UTM and other map projections. The code samples section contains sample code for converting coordinates to UTM coordinates for almost any programming language. ... | |

| #125021 | I want to add UTM coordinate conversions to a webpage, is this possible ? |
| Sure, this is possible. You can implement the code on the clientside using JavaScript, or run it on the server side using ASP, PHP or ASP.NET. A client side (Internet Explorer only) demo can be found here: Convert GPS coordinates to UTM using JavaScrip Server Side (Windows Web ... | |

| #125025 | I want to transform the coordinates from my GPS receiver to UTM. Which source datum should i use ? |
| These days, almost any GPS receiver uses WGS84 as map datum. To be sure you can have a look at the NMEA data, some receivers output the map datum used. If you see something like $GPDTM,W84 the receiver uses WGS84. ... | |

| #125030 | Is it possible with you software to convert GPS coordinates to U.S. State Plane coordinates ? |
| Yes this is possible. You can convert from any source coordinate to State Plane coordinates by just supplying the State Plane number. For a list of supported state planes, have a look at this page. ... | |

| #125040 | The U.S. stateplane I am using is defined in meters, but I want the output coordinates to be in feet. How can this be done ? |
| This is possible. You only have to add a couple lines to your existing code. When converting to State Plane coordinates, you normally use the following code to convert from latitude / longitude to northing / easting coordinates: Set objProjection = CreateObject ( "Eye4Software.GpsProjecti ... | |

| #125050 | What source datum is used when converting to UTM using the ToUTM function ? |
| When using the ToUTM function, only the destination datum has to be passed as parameter. The source datum used is always WGS84, this datum is choosen because GPS coordinates are allways in WGS84 (unless the GPS receiver is configured otherwise). In case you want to convert directly to UTM from ... | |

| #125051 | What destination datum is used when converting from UTM using the FromUTM function ? |
| When using the FromUTM function, only the source datum has to be passed as parameter. The destination datum used is always WGS84, this datum is choosen because GPS coordinates are allways in WGS84 (unless the GPS receiver is configured otherwise). In case you want to convert directly from UTM t ... | |

| #125060 | Can I use your GPS SDK to calculate the distance between two coordinates ? |
| Yes, it is possible to do high precision distance calculations using the GPS Toolkit. Instead of the Great Circle formula, it uses Vincenty's formula which far more accurate. The function to calculate the distance takes the source and destination coordinates in latitude / longitude format. ... | |
