Yea, it's actually keyed to population, but the latest GNIS files
are missing that column as I recall.  That actual population
switching points are hard-coded in Xastir.

[Xastir] Display levels with GNIS files

2007-08-22 Thread Alex Carver
Hmm, the vast multitude of interweb tubes ate my last
message.  Let's try again. :)

Playing around with the GNIS files, I've filtered them
down a bit so that I'm not swamped with 30,000 records
but I wanted to know what exactly is controlling
whether a GNIS feature displays or doesn't at a
particular zoom level.  Is it inside Xastir or is the
threshold in the GNIS file (keyed to population)?

Danke

It's hard coded.

I have considered converting my GNIS files to shapelib just so I  
could create a dbfawk to control them.
