I wonder if they've purposely introduced some GPS-style innaccuracies in the trial version? [Peter Drayton's Radio Weblog] It appears the affect is due to rounding. When I go to http://www.serviceobjects.com/products/GeoNet_demo.asp they list my location as Omaha, NE. Longitude: -96, Latitude: 41. But Tiger shows Omaha, NE at Longitude: -96.01174, Latitude: 41.26390. (http://www.census.gov/cgi-bin/gazetteer-tbl?city=omaha&;state=ne&zip=) Compare these 2 maps and you’ll see the difference I see on your map: Precise: http://tiger.census.gov/cgi-bin/mapbrowse-tbl?lat=41.26390&;lon=-96.01174&wid=0.25&ht=0.25&mlat=41.26390&mlon=-96.01174&msym=redpin&off=CITIES&mlabel=Omaha,+NE Rounded: http://tiger.census.gov/cgi-bin/mapsurfer?infact=2&;outfact=2&act=move&off=CITIES&tlevel=-&tvar=-&tmeth=i&mlat=41&mlon=-96&msym=redpin&mlabel=Center&murl=&lat=41&lon=-96&wid=0.250&ht=0.250&conf=mapnew.con    ... Virtual reality lets parents "touch" fetus in womb. A new computer system combines 3D imaging and virtual reality devices to give parents the chance to "feel" their unborn baby [New Scientist] I hope my daughters let me come see their ultrasounds in 40 years. (I have 3 girls: 10, 9, 3. Plus we have another girl on the way. And yes I hope it is 40 years before any of them need an ultrasound ;-) )    ...
