The four cardinal directions, or cardinal points, are the four main compass directions: north, south, east, and west, commonly denoted by their initials N, S, E, and W respectively. Relative to north, the directions east, south, and west are at 90 degree intervals in the clockwise direction.
Left-hand traffic ( LHT) and right-hand traffic ( RHT) are the practices, in bidirectional traffic, of keeping to the left side and to the right side of the road, respectively. They are fundamental to traffic flow, and are sometimes called the rule of the road. [1] The terms right- and left-hand drive refer to the position of the driver and the steering wheel in the vehicle and are, in ...
High-definition maps for self-driving cars usually include map elements such as road shape, road marking, traffic signs, and barriers. [4] [10] Maintaining high accuracy is one of the biggest challenges in building HD maps of real-world roads. With regard to accuracy, there are two main focus points that determine the quality of an HD map: Global accuracy (positioning of a feature on the ...
DeepMap was founded in Palo Alto, California in 2016 to create 3D mapping software to assist self-driving cars with navigation. [1] Founders James Wu and Mark Wheeler were co-workers on Google Maps, and before that at Apple and Baidu. [7] Wu became the company's CEO, and Wheeler became its Chief Technology Officer. [1] Also in 2016, the company raised $7 million in initial funding. [8]

South-up map orientation is the orientation of a map with south up, at the top of the map, amounting to a 180-degree rotation of the map from the standard convention of north-up. Maps in this orientation are sometimes called upside down maps or reversed maps. [citation needed] Other maps with non-standard orientation include T and O maps, polar ...
The history of cartography refers to the development and consequences of cartography, or mapmaking technology, throughout human history. Maps have been one of the most important human inventions for millennia, allowing humans to explain and navigate their way through the world.
The azimuthal equidistant projection is an azimuthal map projection. It has the useful properties that all points on the map are at proportionally correct distances from the center point, and that all points on the map are at the correct azimuth (direction) from the center point. A useful application for this type of projection is a polar ...
