Keyhole Markup Language ( KML) is an XML notation for expressing geographic annotation and visualization within two-dimensional maps and three-dimensional Earth browsers. KML was developed for use with Google Earth, which was originally named Keyhole Earth Viewer. It was created by Keyhole, Inc, which was acquired by Google in 2004.
Keyhole Markup Language (KML) is a file format used to display geographic data in an earth browser, such as Google Earth, Google Maps, and Google Maps for mobile browsers "Google KML definition" Geospatial Semantic Web
GML and KML. KML, made popular by Google, complements GML. Whereas GML is a language to encode geographic content for any application, by describing a spectrum of application objects and their properties (e.g. bridges, roads, buoys, vehicles etc.), KML is a language for the visualization of geographic information tailored for Google Earth. KML ...
GPX, or GPS Exchange Format, is an XML schema designed as a common GPS data format for software applications. It can be used to describe waypoints, tracks, and routes. It is an open format [2] and can be used without the need to pay license fees. Location data (and optionally elevation, time, and other information) is stored in tags and can be ...
The shapefile format is a geospatial vector data format for geographic information system (GIS) software. It is developed and regulated by Esri as a mostly open specification for data interoperability among Esri and other GIS software products. [1] The shapefile format can spatially describe vector features: points, lines, and polygons ...
Method 2. Example of KML code displayed within a browser window. If after clicking on the KML file link, a plain page full of code is displayed (see image for example): Select the entire contents of the page ( Ctrl + A on Windows, ⌘ Cmd + A on Macintosh), and then copy it ( Ctrl + C on Windows, ⌘ Cmd + C on Macintosh) Paste the contents ...
Well-known text representation of geometry. Well-known text ( WKT) is a text markup language for representing vector geometry objects. A binary equivalent, known as well-known binary ( WKB ), is used to transfer and store the same information in a more compact form convenient for computer processing but that is not human-readable.
Keystroke-level model. In human–computer interaction, the keystroke-level model ( KLM) predicts how long it will take an expert user to accomplish a routine task without errors using an interactive computer system. [1] It was proposed by Stuart K. Card, Thomas P. Moran and Allen Newell in 1980 in the Communications of the ACM and published in ...
