$Source: /cvs/distapps/openmap/README,v $ $RCSfile: README,v $ $Revision: 1.11 $ $Date: 2002/11/06 19:11:02 $ $Author: bmackiew $ OpenMap(tm) What is it? ----------- OpenMap is a Java Beans based toolkit for building applications and applets needing geographic information. Using OpenMap components, you can access data from legacy applications, in-place, in a distributed setting. At its core, OpenMap is a set of Swing components that understand geographic coordinates. These components help you show map data, and help you handle user input events to manipulate that data. What are the license terms for using OpenMap? --------------------------------------------- Take a look at the file called LICENSE in the distribution. We want you to be able to do pretty much anything with it as long as we get credit for our work and as long as you offer your changes to us so we can possibly add them to the standard version we distribute. OpenMap is a trademark ---------------------- OpenMap is a trademark of BBN Corporation. Just so you're not confused, BBN Corporation is the legal entity, but we're actually part of Verizon Communications. Technically, we do business as "BBN Technologies, a part of Verizon". Downloads and home page ----------------------- The homepage is at: Downloads of the current distribution are available from the homepage. Where to start? ------------------------ - OpenMap Viewer The com/bbn/openmap/app/OpenMap.java example is the default "face" of OpenMap. While it looks like a complex example to start with, it's really a simple framework that uses the MapHandler to add and connect the OpenMap components. See the viewer User's Guide (http://openmap.bbn.com/doc/user-guide.html) for more information. You can write your own components that can display your data in the OpenMap Viewer. Once you've written the layer or plugin, all you need to do is to add a reference to it in your openmap.properties file. The OpenMap Viewer reads this file to get configuration information. The properties file has instructions for adding layers and plugins to the application. Likewise, you can change the look of the application by modifying the openmap.components property in the openmap.properties file. There are instructions in the properties file for modifying this property, but the main point is that changing the application does not require a code change. The components are defined in the openmap.properties file and are connected at runtime. - SimpleMap This class is a very simple example that shows how you use the MapBean and a layer which shows a map of the world. This com/bbn/openmap/examples/simple/SimpleMap.java uses the MapBean to create a static political map in a window with these steps: 1. Create a JFrame window. 2. Create a MapBean. 3. Create the Political boundary Layer 4. Add the Layer to the MapBean. 5. Add the MapBean to the ContentPane of the JFrame. 6. Show the JFrame window. - SimpleMap2 This com/bbn/openmap/examples/simple/SimpleMap2.java example is a little more complicated than the previous one, but is more usable. It shows the same political layer along with a background graticule layer (com/bbn/openmap/layer/GraticuleLayer.java) and a simpleforeground layer (com/bbn/openmap/examples/simple/RouteLayer.java) which shows hypothetical transportation routes. This RouteLayer is a good example of how to extend the Layer class to create your own Layer (More about this can be found in the architecture documentation at http://openmap.bbn/doc/openmap-arch.html). This example program also includes OpenMap GUI widgets for navigating around on the Map. The steps involved in creating the program are: 1. Create a JFrame window. 2. Create a MapBean. 3. Set the center and scale of the MapBean. 4. Create the Political, Graticule, and Route layers. 5. Add the layers to the MapBean. 6. Create GUI widgets. 7. Add the GUI widgets to the ContentPane of the JFrame. 8. Add the MapBean to the ContentPane of the JFrame. 9. Show the JFrame window. Since the MapBean is a PanListener and ZoomListener, you can create an object that produces these events and hook it up to the MapBean in order to "drive" the map. The ToolPanel object generates PanEvents and ZoomEvents which are used to control the MapBean. - HelloWorld The com/bbn/openmap/examples/hello/HelloWorld.java example extends the ideas developed in the SimpleMap2 example. It again uses the MapBean to show a political map of the world, but this time with a blazing "Hello World!" painted over the map. It also incorporates Mouse events to allow point-and-click navigation. The openmap.properties file ------------------------ The OpenMap application is configured at runtime by the contents of the openmap.properties file. The openmap.properties file is located in the openmap directory, and has guidance inside it on how to modify various properties to change a) what components are part of the OpenMap application, including what layers are available, b) how those components are configured, and c) the initial map projection used by the application. When the OpenMap application starts up, the PropertyHandler object checks the CLASSPATH to find an openmap.properties file, and then checks the user's home directory for one. If an openmap.properties file was found in the home directory, all of its properties get added to any properties created previously from a CLASSPATH openmap.properties file. If there are duplicate properties, the last version read (from the home directory) will be the version used. By default, there is an openmap.properties file located at the top level of the openmap.jar file. When the jar file is created, the openmap.properties file located in the top level openmap directory gets copied to the classes/openmap directory, and then included into the openmap.jar file. If you make modifications to the openmap.properties file, those changes will not be reflected in the application unless: 1. The top level openmap directory is included in the CLASSPATH of the OpenMap application. This can be done by modifying the openmap startup scripts located in the bin directory. 2. The openmap.properties file is copied into your home directory. For unix users, this directory is usually /home/. For Mac OS X users, this directory is /Users/. For Windows users, this directory is D:\Documents and Settings\, where D: is the disk windows is installed on. If you are not sure where your home directory is, you can compile this code into a HomeDir.java file and run it: public class HomeDir { public static void main(String[] argv) { System.out.println("User home directory is " + System.getProperties().getProperty("user.home")); } } 3. You put the openmap.properties file in the top level of the openmap.jar file, either by a) recompiling the openmap code, or b) unpacking the jar file, replacing the openmap.properties file, and repacking the jar file. The second option is usually the easiest, but your needs may require one of the other options. Anonymous CVS repository ------------------------ There is currently no anonymous CVS access. Please let us know if this service would be valuable to you. Bug Tracking Software --------------------- BBN maintains a Bugzilla site for tracking bugs and suggestions for OpenMap. You can find it at: Mailing lists ------------- BBN runs an "openmap-users@bbn.com" mailing list that addresses common OpenMap questions, comments, criticisms, bug reports, patches, and notifications of new releases. To join this mailing list, send email to majordart@bbn.com with "subscribe openmap-users" in the body of the messages. You can find archives of this mailing list at: http://openmap.bbn.com/mailArchives/openmap-users/ (Use "openmap" for both the username and password.) You can also reach the OpenMap development team directly at openmap@bbn.com Please help out! ---------------- There's much room for improvement of the OpenMap sources. We are interested in any changes you make to the core source, or layers you develop, or other derivative works. Regression testing ------------------ DejaGNU? Related groups and projects --------------------------- The OpenGIS Consortium
