Posted by hclinch Wednesday, 15 August 2007- 8:43 pm
Hi Cip,

Susan (professor of planning at the University of Alaska) has just
uploaded a pdf and text file showing the form & fields for her
database for Fairbanks Greenmap
( - it's in the Mapmaking
section of the Tool Center (text file, tab-delimited) (pdf)

Hope this is useful...

Thanks for putting these up Susan!
