There are concerns about the ability of ArcGIS 10 to fulfill a requisite of mine.
ET Geowizards has been tried, although it doesn't have the same capability of ArcGIS e.g. I cannot aggregate all of the points I have with ET, to the scale I have them plotted.
There is a memory leak, which means looping through 700 objects, performing:
- Agg Points.
- Add Field.
- Update cursor.
Starts off taking 5-9 secs per object, and continues on to 2 mins per (similarly sized) object.
In SP2, it appears AggPoints no longer works to create an FC on the fly. There is more, but it's too long a list to compile!
Code, simplied with no buffer, add field or cursor. geom is a collection or arcpy points
def createGeom(geom, scratchDB): filetime = (str(time.time())).split(".") outfile = "fc" + filetime+filetime outpath = scratchDB + "tmpV.gdb/Polygon/" outFeatureAggClass = outpath+outfile +"_Agg" arcpy.AggregatePoints_cartography(geom, outFeatureAggClass,"124000 meters")
Seems to be that the size of the file geodatabase we're writing to is one of the main issues; I think the problem is that performance degrades as the local file geodatabase fills up - significantly.
Any ideas how to tune local file geodatabase?
