Hello, This is a great first question. I wish we had a tutorial just to answer this question and I hope to build one eventually. For now you are going to have to work your way through some things on your own.
First, your question is actually incomplete. We could easily generate a data set with a point at each of those coordinates, as I will explain below. However, if you then expect to match these coordinates to other geographic data, you have to have slightly more information, namely the projection system you are using. Your data do not seem to be longitudes and latitudes but some other projected data; you will therefore need to find out what projection they are using. If all you want to do is create a file of geometric points at those coordinates, then you are essentially going to be using the JTS library since this is what Geotools uses. You could look on the JTS web site or you could read the current documentation prototype at: http://docs.codehaus.org/display/GEOTDOC/Programmers+Manual+Prototype and checkout the tutorial file http://docs.codehaus.org/download/attachments/50776/GnuGIS_Geotools_Tutorial000010_Geometry010_Creation.java?version=1 Note these are both prototypes, in early stages, and so are less elegant than they could be but they should get you started. However, because you are not using any projection information, THIS WILL NOT GIVE YOU POINTS THAT YOU CAN MATCH TO OTHER DATA. You have been warned. To do that you will need to build projection data and use both your geometry and the projection info to build a geotools feature. I'm hoping to write a tutorial about this shortly. Look around at the web site for more info. It would be nice to have a helper function in Geotools to do this simple operation and perhaps we can add that eventually. Good luck, sincerely, adrian custer On Sun, 2006-07-09 at 19:13 -0400, Natarajan, Senthil wrote: > Hi, > > I was wondering is it possible to generate a Map using GeoTools API > for a set of Lat/Long points. > > Basically I need to generate a Map for these Locations. > > X, Y > > 566469,4181502 > > 567309,4177908 > > 567306,4178221 > > 563567,4182488 > > 563601,4182221 > > 560531,4181786 > > > > If it is possible could you point out some example code how to > generate the Map.
