What is Transverse Mercator used for?
The transverse Mercator projection is appropriate for mapping large-scale or smaller areas with predominantly north-south trending extents. It is a very commonly used projection. Various countries use it for their topographic maps and large-scale coordinate systems.
Where is the scale correct on a Transverse Mercator chart?
The scale is true on the central meridian. The projection is reasonably accurate near the equator. Scale at an angular distance of 5° (in latitude) away from the equator is less than 0.4% greater than scale at the equator, and is about 1.54% greater at an angular distance of 10°.
Is UTM a firewall?
Originally called unified threat management (UTM), these capabilities better known as a Next-Generation Firewall (NGFW) today, provide multiple security features and services in a single device or service on the network, protecting users from security threats in a simplified way.
What are the uses of Mercator projection?
Criticisms of the Mercator Projection. To keep longitude lines straight and maintain the 90° angle between the latitude and longitude lines, the Mercator projection uses varying distances between latitude lines away from the equator . As a result, the Earth’s poles and landmasses closest to them are distorted.
What does the Mercator projection look like?
Mercator projection. n. A cylindrical map projection in which the meridians and parallels appear as lines crossing at right angles and in which areas appear greater farther from the equator.
What does Universal Transverse Mercator grid mean?
Dictionary of Military and Associated Terms (0.00 / 0 votes)Rate this definition: universal transverse mercator grid. A grid coordinate system based on the transverse mercator projection, applied to maps of the Earth.
How does Universal Transverse Mercator (UTM) work?
The transverse Mercator map projection is an adaptation of the standard Mercator projection which flips the cylinder 90 degrees (transverse). The UTM projection flattens the sphere 60 times by shifting the cylinder central meridian 6° for each zone. This gives cartographers a map to work with always in meters. The Universal Transverse Mercator is horrible for small-scale (less-detailed) maps like world atlases and perfect for mapping narrow regions.
