CRD Natural Areas Atlas
Congratulations to the Capital Regional District on the Award of Excellence they recently received at ESRI Canada's Regional User Conference in Victoria. This recognition is well deserved and is a long time coming. 
Although we’ve helped build lots of applications, CRD's popular Natural Areas Atlas is special to me. Unofficially launched in April 2001, the Natural Areas Atlas was the first public facing custom-built ArcIMS application developed by Latitude Geographics. At the time Latitude Geographics was about four people, and we volunteered to build the first version at virtually no cost so we’d have something to show HRH Prince of Wales (a.k.a. Prince Charles) during his official visit to Canada. We’d been selected to present our newfangled Internet mapping technology to him in Regina and needed a public facing app to actually demonstrate! If memory serves, the first version of the Natural Areas Atlas was completed about two days before the big demo. It may well be that the first member of the “public” who viewed the Natural Areas Atlas was the Prince of Wales.
The application has evolved considerably since then, and it got redeveloped from the original ASP code (modified and adapted by CRD over time) and migrated to Geocortex IMF two or three years ago.
