Jody - I looked over the routing algorithms in org.geotools.graph. They look very good.
I am looking for routines that can create a route around islands and coastlines - I believe I need some routines to create visibility graphs around convex hulls. Are you aware of any methods for this or anyone doing this kind of work? -Peter -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jody Garnett Sent: Monday, June 05, 2006 4:29 AM To: sherif attia Cc: Geotools users list Subject: Re: [Geotools-gt2-users] geotools sherif attia wrote: > Message body follows: > > dear sir, > > i am willing to develop a map navigation system on a PDA > so there are somethings i would like to know about geotools > > first, is it supported by J2ME second, does it support routing on GIS maps ?? > J2ME? I think I have seen someone use it there, may need to grab a branch and remove dependence on things like JAI for raster support. Out of the box no, anything important that J2SE specific - advanced raster support. The hard part of routing is data, and data collection. GeoTools does contain an excellent graph package that supports some routing algorithms. But for a real system you need to know a lot of details about say the roads being navigated, what way you can turn at intersections what direction the roads are in etc... If you have that information you can easily feed it into the GraphBuilder and perform queries etc... > meaning: i have GIS map, shape file--> can i use geotools > to turn it to form of network ( nodes and edges ) so that > i can apply dijkstra and if that possible, what packages i need to use?? > > thanks for your help > ext/graph, the tutorial is okay, and the module has the highest test coverage (a measure of quality) in the library.
