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]
In mathematics, particularly topology, an atlas is a concept used to describe a manifold. An atlas consists of individual charts that, roughly speaking, describe individual regions of the manifold. In general, the notion of atlas underlies the formal definition of a manifold and related structures such as vector bundles and other fiber bundles.
The purpose of this tutorial is to show how to create a vector graphics topological map of a single rapid transit, tram, railway, waterway, road or long footpath, etc, route. Topological maps are straight-line diagrams or schematics that display not only the routes, but also other information such as stations and travel zones (as in the case of ...
The various features shown on the map are represented by conventional signs or symbols. For example, colors can be used to indicate a classification of roads. These signs are usually explained in the margin of the map, or on a separately published characteristic sheet. [17] [18] [19] Topographic maps are also commonly called contour maps or ...
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 ...
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.
OpenRailwayMap (ORM) is an online collaborative mapping project developing a worldwide railway map using technology based on the OpenStreetMap project. The project is part of the OpenStreetMap database, and acts as a renderer for the existing OpenStreetMap database to include additional information for railroad lines worldwide. [2]
