Colorado Land Surveyor Practice Exam 2025 – Complete All-in-One Guide to Exam Success

The Colorado coordinate system of 1983 north zone is indeed best described as a system based on the North American Datum of 1983 (NAD 83), featuring specific standard parallels. This system employs a Lambert conformal conic projection, which is useful for mapping regions that are wider in the east-west direction than in the north-south direction, as is the case in Colorado. By establishing standard parallels, the system minimizes distortion in areas close to these lines, making it more accurate for land surveying tasks.

Standard parallels are critical in cartography because they help maintain scale and area accuracy throughout the projection. In the context of the Colorado north zone, this means that all areas and distances can be measured more reliably, which is particularly important in surveying practices where precision is paramount.

The other descriptions do not capture the essence of the Colorado coordinate system of 1983 north zone as effectively. The Lambert conformal conic projection aspect is important, but the emphasis lies on the relationship to NAD 83 and the use of specific standard parallels for accuracy in mapping. A rectangular coordinate system for urban areas would not encompass the broader applicability of the system across varied terrains. Lastly, while a geographic coordinate system uses degrees and minutes to specify locations, it lacks the
