"When we started data collection in 1996," explains Kim Garbade of England-Thims &
Miller, "because of the state of the existing technology, we would go out with two teams: one that collected the attribute and image data and the other that collected the feature's coordinates. We would postprocess this data into shapefiles." As GIS technology has evolved, COJ has improved the process and can collect photographic, attribute, and
positional data simultaneously with a one-man crew.
