hi :) i'm ikbal new with geotools i'm working with closest path :) in modul of graph , i used the snap point to line to localise the points at first exactly on lines
but i had some problems in snap point ? 1- as the tutrial said it compart the point of line with point that i choosed . but the problem there is lines more closest but it's ignore them 2- there is even line where there a ******** so ofcourse there is point ? 3- the shape file i work with is a MULTILINESTRING is there something i miss ? and if every one had the same problem or someone guess pleassee contact me 2015-05-01 7:38 UTC+02:00, geotools-gt2-users-requ...@lists.sourceforge.net <geotools-gt2-users-requ...@lists.sourceforge.net>: > Send GeoTools-GT2-Users mailing list submissions to > geotools-gt2-users@lists.sourceforge.net > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.sourceforge.net/lists/listinfo/geotools-gt2-users > or, via email, send a message with subject or body 'help' to > geotools-gt2-users-requ...@lists.sourceforge.net > > You can reach the person managing the list at > geotools-gt2-users-ow...@lists.sourceforge.net > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of GeoTools-GT2-Users digest..." > > > Today's Topics: > > 1.
