GPS Toolkit Introduction

The Eye4Software GPS toolkit for Java is a GPS SDK (Software Developer Kit) which allows software developers to add coordinate conversion functionality to their own software, without the need to have any knowledge on geodesy and map projection formulas.

The GPS toolkit for Java offers the following features:

• Convert (GPS) coordinates from one map datum to another;
• Convert coordinates between NAD83 and NAD27 using NADCON correction files;
• Convert coordinates between NAD83 and NAD83(HARN) using HARN/HPGN correction files;
• Convert coordinates between different map datums using NTv2 correction files;
• Convert (GPS) coordinates from one coordinate system or map projection to another;
• Convert (GPS) coordinates to U.S. State Plane Coordinate System (SPCS27 or SPCS83);
• Convert (GPS) coordinates to UTM coordinates;
• Built-in support for more then 500 map datums and 5000 map grids;
• Simple distribution, you only have to ship a single JAR file with your application;

The GPS control can be used to develop GPS projects for one of the following operation systems:

• Linux x86;
• Linux x64;
• Windows x86;
• Windows x64;
• Mac OS X;
• Solaris x86;
• Solaris x64;
• Solaris SPARC (32 bit);
• Solaris SPARC (64 bit);
• Android;

Use the GPS toolkit for Java from the Eclipse IDE.	Use the GPS toolkit for Java from the Netbeans IDE.

GPS Toolkit Features

Perform GPS coordinate conversions

The latitude and longitude coordinates from either a GPS or set manually, can be converted to any map datum or map grid around (for instance to UTM or SPCS), by just using the built in "IGpsProjection" interface.

The GPS Toolkit contains a database with over 3500 map grid and 300 map datum definitions. The database is integrated in the JAR archive. You can use all these map grids and map datums directly from your software with only a few lines of code. In case a grid or datum is not in this database, you will be able to define it by yourself by setting its parameters.

The map projections supported by the software include:

• Transverse Mercator;
• Transverse Mercator South Orientated;
• Oblique Mercator;
• Hotine Oblique Mercator;
• Swiss Oblique Mercator;
• Mercator 1SP;
• Mercator 2SP;
• Oblique Stereographic;
• Polar Stereographic;
• Albers Equal Area Conic;
• Lambert Conformal Conic 1SP;
• Lambert Conformal Conic 2SP;
• Lambert Conformal Conic West Orientated;
• Lambert Azimuthal Equal Area;
• Krovak and more.

Requirements

In order to use the GPS toolkit for Java, you need to have the Java Runtime Environment installed on your computer. When installing on a development computer, you have to install the Java Developers Kit instead.
