How easy is the library to use? The best way to show its ease of use is with an example. Here is a conversion from latitude/longitude to UTM:

hFrom = ProLatDefineLatLong ("WGS84")
hTo = ProLatDefineUTM ("WGS84", 17, 0, "m")
fX(0) = -81 ' Put a coordinate in an array
fY(0) = 35
ProLatTransform (hFrom, hTo, fX(0), fY(0), fZ(0), 1) ' Transform values in-place

A more complex conversion is just as easy. Here is a conversion from State Plane (Montana South) in NAD27 to UTM in WGS84 with a datum shift:

hFrom = ProLatDefineSPCS ("NAD27", 2503, "us-ft")
hTo = ProLatDefineUTM ("WGS84", 12, 0)
fX(0) = 2381348 ' Put a coordinate in an array
fY(0) = 732801
ProLatTransform (hFrom, hTo, fX(0), fY(0), fZ(0), 1)

To get a reverse transformation, simply swap the hFrom and hTo parameters.

Licensing and Support

ProLat DLL software requires one license for each developer work-station where it is used for development even if the software is installed on a server. ProLat DLL requires one license for each server where it is used by end-users. No additional licenses or royalties are required for distribution with your application that includes and uses the redistributable prolat.dll file. See complete licensing details.

Technical Support

Support is provided to developers to help with installation issues and understanding the capabilities of the software. Support for code development, debugging, projection parameters, and end-users is available with development support or by contract. Of course bug resolution is free.

Software Support

Visual Basic ProLat DLL was designed to widely support many languages with Visual Basic especially in mind. With a few simple functions, you can add powerful conversion features to your programs. An included Visual Basic example implements a complete graphical calculator with all of the supported parameters. (Shown at right.) This might be the solution you need with no programming after all. Or, copy and paste what you need to your application. Examples are in VB 6 and VB.NET.
Excel ProLat is perfect for coordinate conversion right in your spreadsheets. An included example gives graphical coordinate system selection with no programming. It allows you to copy and paste data for quick conversion. Or, you can include the conversion macro functions right in your own spreadsheet if you have a little knowledge of Excel VBA macros. No programming necessary, just copying and pasting.
C/C++ and C# ProLat DLL includes six C++ console examples that show various combinations of coordinate conversion parameters. Examples include NAD27 datum to NAD83 datum, State Plane, and UTM conversions. A C# class and example is provided to get coordinate conversion integrated into your C# application. MS Access Now integrating coordinate conversion into Access is easy. ProLat DLL includes an example with the necessary module definitions. You retrieve the coordinates from your tables into an array and ProLat does the rest to provide easy conversion. Other Languages ProLat DLL works well in any language that is able to call Win32 DLL functions. Use the complete function reference and the C examples for a complete description of the parameters. Possible languages include: Delphi/Pascal PowerBASIC and REALbasic NI LabVIEW Agilent VEE More...

Documentation

A PDF manual provides complete instructions for using the DLL and examples. It's function reference gives details for using the functions and clearly explains the parameters and how they affect the conversions. The manual gives an overview of each supported coordinate system with special information.
