You can create custom Coordinate implementations, and coordinate sequence implementations that allow the use of metadata for each location in your track.
Out of the box JTS Coordiante does x,y,z - you can see we have a few implementations that focus on representing only xy as a coordinate sequence backed by an array. You can actually go the other direction and create a Coordinate that maintains additional "measures" (although this is not very common). JTS will politely leave that information alone, but can cary it around it the data structure for you. You can see a few functions for linear referencing, you would want to create a similar approach for accessing your metadata. Perhaps try asking on the JTS list for additional tips and tricks? -- Jody Garnett On October 17, 2014 at 6:01:37 AM, Anthony F (afc...@gmail.com) wrote: Hi all, I have been digging around in geotools looking to see if it supports tracks and have so far come up empty handed. I'm looking for advice and best practices on how to work with tracks. Basically, I want to store a LineString so that I can do proper geospatial queries on the geometry. Each point in the LineString has meta-data associated with it. I've thought about storing parallel arrays of the attributes associated with each way point. I have found the kml extension namespace which supports Tracks and MultiTracks but I don't know how to work with it within geotools. I have also found dynamicFeatures within the GML namespace but I'm not sure how that gets parsed by geotools. If anyone has any code samples they can point me to, I'd appreciate it.
