Question
TRUE/FALSE (15 points) A distance is measured with a 50-ft steel tape and is found to be 896.24 ft. Later the tape is standardized and is found to have an actual length of 50.02 ft. Therefore, the correct distance is greater than 896.24 ft. The ellipsoid is the shape of the earth that is based on gravity measurements. The Mercator projection is a cylindrical map projection created in 1569. It is the best map projection in the world because of its long history transferring three-dimensional earth positions onto two-dimensional map positions angle Geographic Information System (GIS) The State Plane Coordinate System in the U.S. was created to minimize disto Angle by repetition is a field operation performed to obtain the best estimate of the value of an Vector and ras 4. 6. ter data models are two ways that real-world features are represented in a The purpose of taking and observing overlapping aerial photographs is to delineate contours.
