Hi,
I also provided a related answer on a similar question on StackOverflow a
few weeks ago. See
http://stackoverflow.com/questions/6060460/it-is-need-to-calculate-the-coordinate-of-the-intersection-point-that-is-between/6214311#6214311
I believe, for example, the postgis function ST_line_locate_point is similar
to the Oracle function "SDO-LRS.LOCATE_PT" and that is the same as the JTS
method LengthIndexedLine.extractPoint so, since JTS is included in Geotools,
then as Jody says, yes these capabilities are there. As a test I added this
example to neo4j-spatial using the syntax SpatialTopologyUtils.locatePoint.
This just wraps the equivalent JTS function.
Regards, Craig

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
