Eric Fischer	ea292def47	Make duplicate trimming less bad: only trim features indexed >1 time	2014-11-06 11:27:10 -08:00
Eric Fischer	c24cfada61	Move feature type to index so point skipping can avoid looking up geometry ... Which should avoid having to page the geometry in if there is more data than will fit in memory	2014-11-05 12:18:03 -08:00

Eric Fischer	ac00c84fb2	Save a little more space by sub-ordering within the same index ... to put the lowest-numbered endpoint last within lines that start at the same point, since that is the one that might come next.	2014-10-21 17:59:42 -07:00
