"This article presents GISCoordinate.java: a class that allows you to represent a GIS coordinate in your JAVA code in decimal degrees (38.4443, e.g. 122.33433), minute degrees (33 44 22E, 122 33 44N), or radian degrees. Also, you can use this class to manipulate the coordinate, moving it around the globe by giving it distances in feet and direction of travel. You then can extract the new coordinate that is calculated after the travel."
"In part one of this Java and GIS series, we acquired the vocabulary that surrounds the GIS space. Understanding the terminology is critical when talking about GIS applications. In part two of this three-part series, we are going to take a look at the mobile Java client. We're going to build a simple Location Based Services (LBS) MIDLet to show what needs to happen on a mobile device and how to get that information to a server. Part three of this series will take the location information and show how a map can be created using the location coordinates. We're assuming that you've got some J2ME background (since we aren't going to be going into detail on the MIDLet life-cycle), as well as background on how to create and deploy a servlet. For our sample, we are working with MIDP 2.0, the Motorola iDEN i730 SDK, and the Motorola i730 device."
