Conformality:When the scale of a map at any point on the map is the same in any direction,the projection is conformal.Meridians(lines of longitude)and parallels(lines of latitude)intersect at right angles.Shape is preserved locally on conformal maps.(协调:当规模的地图,在地图上的任何一点在任何...
1. Two sets of parallel lines intersecting at right angles and forming squares; the grid is superimposed on maps, charts, and other similar representations of the Earth's surface in an accurate and consistent manner in order to permit identification of ground locations with respect to other locat...
Parallels and meridians were represented by straight lines intersecting each other at right angles, the relative proportions between degrees of longitude and latitude being retained only along the parallel of Rhodes. The distortion of the countries represented would thus increase with the distance, north...
This kind of map projection has straight coordinate lines with horizontal parallels crossing meridians at right angles. All meridians are equally spaced and the scale is consistent along each parallel. Cylindrical map projections are rectangles, but are called cylindrical because they can be rolled up...
It became the standard map projection for nautical purposes because of its ability to represent lines of constant course, known as rhumb lines or loxodromes, as straight segments that conserve the angles with the meridians. Advantages: The two properties, conformality and straight rhumb lines, make...

In 1569 Gerhardt Mercator (1512-1594) constructed the chart now called Mercator's Map. On it the meridians and parallels are sets of parallel straight lines at right angles, a course on the Earth's surface always cutting the meridians at the same angle is a straight line cutting the meridia...
This paper presents a pioneering solution to the task of integrating mobile 3D LiDAR and inertial measurement unit (IMU) data with existing building information models or point clouds, which is crucial for achieving precise long-term localization and mapping in indoor, GPS-denied environments. Our ...
There are two main observations from Figure 5: the first one is that the alternative roads and OSM main car roads do not necessarily geometrically run in parallel but intersect with each other, forming acute angles. Therefore, the process of revising OSM main car roads should be rooted in top...
This selection carries with it the appropriate mathematical mapping formulae and distortions associated with the selected mapping (Lee, 1976). The observed angles ω, azimuths α, and distances S (that had been first reduced to the reference ellipsoid) are then reduced further (distorted) onto ...
