The central meridian is the centerline of longitude for projection systems. Projected coordinate systems often use it as a reference point for an x-origin . For example, the state plane and UTM projection systems use a central meridian.

Jun 27, 2024 · On the other hand, the central meridian is the line of longitude that is chosen as the starting point for mapping a specific area. It is often selected based on its proximity to the center of the region being mapped.

Central meridian may mean: Central meridian (astronomy), the meridian that goes through the centre of the body's disc as seen from the point of view of the observer; Central meridian (map projections), a line used to define the origin of some map projections

This BLM map depicts the principal meridians and baselines used for surveying states (colored) in the PLSS. The following are the principal and guide meridians and base lines of the United States, with the year established and a brief summary of what areas' land surveys are based on each.

Instead of using latitude and longitude coordinates, each 6° wide UTM zone has a central meridian of 500,000 meters. This central meridian is an arbitrary value convenient for avoiding any negative easting coordinates. All easting values east …

May 13, 2020 · The central meridian is the inside line of longitude for projection systems. projected coordinate systems often use it as a kind of perspective point for an x-region. Here are a few instances of the central meridian in coordinate systems.

Most zones in UTM span 6 degrees of longitude, and each has a designated central meridian. The scale factor at the central meridian is specified to be 0.9996 of true scale for most UTM systems in use.

The central meridian is the longitude at the center of the zone and is equal to 3 degrees multiplied by the zone number minus 183 degrees. Calculate the easting and northing values relative to the central meridian of the UTM zone.
