To some extents it makes it easier but I wish there was a way to implement “unclassified” option as well.All Things Spatialhttps://www.blogger.com/profile/10413714814303264541noreply@blogger.comtag:blogger.com,1999:blog-6221900824469142147.post-86777780161240274922012-07-11T19:55:34.184+10:002012-07-11T19:55:34.184+10:00The Data Packs became available this week.

A more convenient format than the plain profiles, but I'll still be waiting for TableBuilder for most of what I'll do.<br /><br />For the 2006 data, I had a Perl script that trawled through hundreds of spreadsheets getting the figures I wanted. No need for that now!<br /><br />What do you use to get the boundaries in a convenient format?<br /><br />In Mappage, I ended op with this rather messy algo to map from a scalar to 0-1.<br />2% and 98% percentiles map to the two ends of the colour range.<br />The figure that mapped to the middle colour value was the average of the 2%, the median (twice) and the 98%.<br />Then I do the same kind of thing again to get the vlaue that maps to the 1/4 and 3/4 colour values. It's a messy halfway between using a linear scale and using a percentile scale.Erichttp://mappage.net.aunoreply@blogger.com
