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 points 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 curvature 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 2015-05-02 16:12 UTC+02:00, nacer med <ikbalna...@gmail.com>: > 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.
