Silly Geographic Precision

I tread water in oceans of latitude longitude coordinates. Every vector data set I encounter is big fat sets of latitude (up-downiness) and longitude (left-rightiness) bits of info which combine (the "co" in coordinates) to pinpoint a spot on the surface of the Earth (and those combine to trace lines or...

The X90 OPUS receiver from CHC Navigation and iGage Mapping intersects affordability with simplicity while delivering excellent precision with the National Geodetic Survey’s Online Positioning User Service.
Product Review: X90-OPUS

The next big thing in precision GPS might not be new technological features, but rather the significant drop in the cost of investment.

GIS to the Rescue

A frantic cell phone call from a snowboarder came into Colorado's Winter Park Ski Resort in the Rocky Mountains northwest of Denver at 4:00 p.m. on Valentine's Day, 2012. The 20-year-old man left the boundary of the ski resort and went into an area known as the side country—ungroomed...

Nightmare on GIS Street: Accuracy, Datums, and Geospatial Data

This subject scares me. I’m not a trained geodesist. I’m not a mathematician. Yet, I’d be derelict in my duty if I didn’t write about this subject. I know enough to be dangerous, and enough to know this subject is going to be a nightmare for people managing geospatial databases...
