[hdf-forum] creating polygons from corner points

[John Huddleston]

Good morning Thomas

In general, with any code, read and write operations in a do loop are going
to be slower than one single write.

In code you could use a two pass operation. On the first pass find the total
number of records to write, set up the array and read in the data, and then
perform one write to the geodatabase.

Subject: [hdf-forum] creating polygons from corner points

Hi,

I am creating polygons from corner points of the OMI-AURA data using Python.
Since I am new to Python I am pretty sure there is much to improve at the
code and hopefully this will speed up the process.

The polygons are created into a File Geodatabase of ArcGIS, so it is highly
appreciated if someone of you is working with ArcGIS and can tell me how to
speed up the process of creating polygons within this code.

Please find the code at: http://pastebin.com/m37c7b7ea

Cheers Thomas
