Colorado Land Surveyor Practice Exam

Which of the following describes the coordinates for the origin in the Colorado coordinate system of 1983 north zone?

1. X - 914,401.8289 meters and Y - 304,800.6096 meters

2. X - 800,000 meters and Y - 300,000 meters

3. X - 1,000,000 meters and Y - 500,000 meters

4. X - 900,000 meters and Y - 400,000 meters

The correct answer is: X - 914,401.8289 meters and Y - 304,800.6096 meters

The coordinates for the origin in the Colorado coordinate system of 1983 north zone are defined specifically with both an X and Y value that accurately represent the reference point used within this coordinate framework. In this system, the origin is set for the north zone at X - 914,401.8289 meters and Y - 304,800.6096 meters. This precise definition is crucial for establishing a baseline from which all other coordinates in the north zone are derived. Understanding the importance of these coordinates is significant for land surveyors, as they provide a consistent reference for mapping and legal descriptions of land. Any inaccuracies outside of this defined origin can lead to errors in property delineation and geospatial analysis. While other choices present numerical values that might appear reasonable, they do not correspond to the established origin in the Colorado coordinate system of 1983 north zone. The correct coordinates ensure conformity with standardized mapping systems crucial for accurate land surveying and planning in Colorado.
