Hi Jason, If your axes were orientated differently, you could get no numbers the same in that list. The are all different coordinates, it is not like you keep going backwards and forwards to the same points in the example you gave.
Maybe I'm confused.

That combined with simplify geometry operations should give you the control you need? Note we also make use of "decimation" to skip over points that would otherwise render into the same pixel; perhaps that code could be a useful example for you? While there is a page in the user guide (http://docs.geotools.org/latest/userguide/library/jts/simplify.html) I could really use a code example if you can produce one :-) -- Jody Garnett On Tuesday, 24 May 2011 at 10:47 AM, Jason Ferguson wrote: I am attempting to store data from the TIGER/Line shapefiles into a database table, but am having issues with reducing the precision from the 5 decimal places to 3 decimal places. What I find is that after I dig down and get the coordinates, then eliminate duplicates, I'm left with a list of coordinates something like this (which I call semi-duplicates for lack of a better term): 45.900, 178.353 45.900, 178.355 45.900, 178.361 45.900, 178.363 I end up with the same latitude, but several intermediate longitudes (or vice versa). I don't need all of these intermediate points, but I realize that this is an artifact of brute force rounding. Is there a "better" way to reduce the decimal precision?
