ISO

ISO 19141:2008 defines a method to describe the geometry of a feature that moves as a rigid body. Such movement has the following characteristics.(a) The feature moves within any domain composed of spatial objects as specified in ISO 19107.(b) The feature may move along a planned route, but it may deviate from the planned route.(c) Motion may be influenced by physical forces, such as orbital, gravitational, or inertial forces.(d) Motion of a feature may influence or be influenced by other features, for example:- The moving feature might follow a predefined route (e.g. road), perhaps part of a network, and might change routes at known points (e.g. bus stops, waypoints).- Two or more moving features may be pulled together or pushed apart (e.g. an airplane will be refuelled during flight, a predator detects and tracks a prey, refugee groups join forces).- Two or more moving features may be constrained to maintain a given spatial relationship for some period (e.g. tractor and trailer, convoy).ISO 19141:2008 does not address other types of change to the feature. Examples of changes that are not addressed include the following:(a) The deformation of features.(b) The succession of either features or their associations.(c) The change of non-spatial attributes of features.The feature's geometric representation cannot be embedded in a geometric complex that contains the geometric representations of other features, since this would require the other features' representations to be updated as the feature moves. Because ISO 19141:2008 is concerned with the geometric description of feature movement, it does not specify a mechanism for describing feature motion in terms of geographic identifiers. This is done, in part, in ISO 19133.

This document is the first of a family of standards. This document defines XML based encoding rules for conceptual schemas specifying types that describe geographic resources. The encoding rules support the UML profile as used in the UML models commonly used in the standards developed by ISO/TC 211. The encoding rules use XML schema for the output data structure schema. The encoding rules described in this document are not applicable for encoding UML application schema for geographic features (see ISO 19136 for those rules).

ISO 19137:2007 defines a core profile of the spatial schema specified in ISO 19107 that specifies, in accordance with ISO 19106, a minimal set of geometric elements necessary for the efficient creation of application schemata. It supports many of the spatial data formats and description languages already developed and in broad use within several nations or liaison organizations.

This document is the first of a family of standards. The Geography Markup Language (GML) is an XML encoding in accordance with ISO 19118 for the transport and storage of geographic information modelled in accordance with the conceptual modelling framework used in the ISO 19100 series of International Standards and including both the spatial and non-spatial properties of geographic features. This document defines the XML Schema syntax, mechanisms and conventions that:(1) provide an open, vendor-neutral framework for the description of geospatial application schemas for the transport and storage of geographic information in XML;(2) allow profiles that support proper subsets of GML framework descriptive capabilities;(3) support the description of geospatial application schemas for specialized domains and information communities;(4) enable the creation and maintenance of linked geographic application schemas and datasets;(5) support the storage and transport of application schemas and datasets; and(6) increase the ability of organizations to share geographic application schemas and the information they describe.Implementers can decide to store geographic application schemas and information in GML, or they can decide to convert from some other storage format on demand and use GML only for schema and data transport.NOTE: If an ISO 19109 conformant application schema described in UML is used as the basis for the storage and transportation of geographic information, this document provides normative rules for the mapping of such an application schema to a GML application schema in XML Schema and, as such, to an XML encoding for data with a logical structure in accordance with the ISO 19109 conformant application schema.

This document is the first of a family of standards. ISO 19135-1:2015 specifies procedures to be followed in establishing, maintaining, and publishing registers of unique, unambiguous, and permanent identifiers and meanings that are assigned to items of geographic information. In order to accomplish this purpose, ISO 19135-1:2015 specifies elements that are necessary to manage the registration of these items.

ISO 19134:2006 specifies the data types and their associated operations for the implementation of multimodal location-based services for routing and navigation. It is designed to specify web services that may be made available to wireless devices through web-resident proxy applications, but is not limited to that environment.
