A diagram of a Texas U-turn, also known as a Texas turnaround (this one with the local road over the limited-access highway) A Texas U-turn, or Texas turnaround, boomerang, or loop around, [citation needed] is a lane allowing cars traveling on one side of a one-way frontage road to U-turn onto the opposite frontage road (typically crossing over or under a freeway or expressway).
English: National Trails System map produced in 2008 to commemorate the 50th anniversary of the National Trails System Act. In addition to the trails, this map shows the unique badges used to guide hikers on each one.
A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size. A video file normally consists of a container (e.g. in the Matroska format) containing visual (video without audio) data in a video coding format (e.g. VP9) alongside ...
The following junction types typically permit U-turns but are not designed specifically for that purpose. Normal at-grade intersections on divided highways often allow traffic traveling on the divided highway to perform a U-turn, often when there is a green light for traffic turning onto the side road, crossing the opposing lanes (left turns in countries where traffic drives on the right ...
An equirectangular projection simply maps the yaw and pitch (longitude and latitude) of a sphere linearly to a rectangular image. It produces a signature curved look. In addition, the distribution of pixel density (which can be visualized with Tissot's indicatrix ) is suboptimal, with the usually more important "equator" getting the lowest density.
The list of national coordinate reference systems (CRS) lists map projections officially recommended for existing countries. Given that every projection gives deformations, each country's needs are different in order to reduce these distortions.
Not all National Topographic System maps strictly follow the National Tiling System's linear grid. Some maps also, as an "overedge", cover land in an area which would otherwise be covered by an adjacent map sheet, simply because the latter area does not contain enough land in Canada to warrant a separate printing.

360-degree videos, also known as surround video, [1] or immersive videos [2] or spherical videos, [3] are video recordings where a view in every direction is recorded at the same time, shot using an omnidirectional camera or a collection of cameras.
