Colorado Land Surveyor Practice Exam

Which description best fits the Colorado coordinate system of 1983 north zone?

1. A Lambert conformal conic projection based on NAD 1983

2. A rectangular coordinate system for urban areas

3. A system based on the North American datum of 1983, with specific standard parallels

4. A geographic coordinate system using degrees and minutes

The correct answer is: A system based on the North American datum of 1983, with specific standard parallels

The Colorado coordinate system of 1983 north zone is best described as a system based on the North American datum of 1983, with specific standard parallels. This projection utilizes a Lambert conformal conic projection methodology, which is designed to minimize distortion of area and shape when mapping regions that have a larger east-west span compared to north-south. The standard parallels are critical in determining how the projection is applied across Colorado, as they help to minimize distortion at those specific latitudes while providing a reliable representation of the state's geography. The emphasis on specific standard parallels is essential in defining the parameters of the coordinate system, making it possible to maintain accuracy for surveying and mapping purposes. This system is widely used in applications involving land surveying, geology, and environmental studies, where precise measurements and geographical awareness are necessary. Understanding this concept is fundamental for professionals operating in Colorado, as it allows them to effectively utilize the state's surveying frameworks.
