comment Speeding up Python calculated timestamp field in ArcGIS Desktop?
Just a note, calling the pre-canned gp functions will be faster most of the time. I explained why in a previous post gis.stackexchange.com/questions/8186/…

comment A lot of pointers to load on map-A better solution
Since OL is client side technology, it will not reduce the amount of data transfered. However, if he were doing server-side clustering, it would help greatly :)

comment Why do valid polygons repeat the same start and end point?
@Kirk it would have been nice if you showed how the rings are laid out; is it a "banana-like" list of coordinates with one outer ring or is it an outer ring with an inner ring that touches the outer ring at only at one vertex?. Even at that, the answer for your particular question is implementation specific. Check out Paul's notes on Polygon validity 2010.foss4g.org/presentations/3369.pdf

comment Is there a standardized or “most used” dummy Z value?
Also, my recommendation was for the usage of NaN was as it relates to the Z value inside the geometry. So regardless of whether the value is in a database or not, IMHO it should be serialized with the geometry - so it should just work...

for integers you can have NaNs: numeric_limits<int>::quiet_NaN()

Did I mention these are descriptions of the internal representations of GDB rel classes? I fixed bugs and maintained the ESRI rel classes for 3 years :)
