RailTopoModel is a systemic data model for describing the topology-based railway infrastructure as needed by various applications. The RailTopoModel has been initially developed under patronage of the International Union of Railways (UIC) and was released as International Railway Standard (IRS) 30100 in April 2016. [1]
An atlas for a topological space is an indexed family {(,):} of charts on which covers (that is, =). If for some fixed n , the image of each chart is an open subset of n -dimensional Euclidean space , then M {\displaystyle M} is said to be an n -dimensional manifold .
In cartography, geology, and robotics, [1] a topological map is a type of diagram that has been simplified so that only vital information remains and unnecessary detail has been removed. These maps lack scale, also distance and direction are subject to change and/or variation, but the topological relationship between points is maintained.
A 242A1 locomotive and standard gauge track at some model railway scales. This page lists the most relevant model railway scale standards in the world. Most standards are regional, but some have followers in other parts of the world outside their native region, most notably NEM and NMRA.
A transit map is a topological map in the form of a schematic diagram used to illustrate the routes and stations within a public transport system—whether this be bus, tram, rapid transit, commuter rail or ferry routes. Metro maps, subway maps, or tube maps of metropolitan railways are some common examples. The primary function of a transit ...
Topographic maps are also commonly called contour maps or topo maps. In the United States, where the primary national series is organized by a strict 7.5-minute grid, they are often called or quads or quadrangles. Topographic maps conventionally show topography, or land contours, by means of contour lines.
Microsoft unveiled Majorana 1, a quantum chip the company says is powered by a new state of matter. The new chip allows for more stable, scalable, and simplified quantum computing, the company says.
Topographic maps, displaying an area's relief, de facto explain many other things such as human occupation, cultivated areas, kingdoms borders, exchanges ways, etc. If you create a topographic map, note that these colorimetric values are indicatives.
