Geographic information - Land Administration Domain Model (LADM) - Part 1: Generic conceptual model (ISO 19152-1:2024)
SIST EN ISO 19152-1:2024

This document:
—     defines a reference Land Administration Domain Model (LADM) covering basic information-related components of land administration/georegulation;
—     provides an abstract, conceptual model with packages related to:
—     parties (people and organizations),
—     basic administrative units, rights, responsibilities and restrictions (RRRs),
—     spatial units,
—     a generic conceptual model (sources and versioned object);
—     provides terminology for land administration/georegulation, based on various national and international systems, that is as simple as possible in order to be useful in practice. The terminology allows a shared description of different formal or informal practices and procedures in various jurisdictions;
—     provides a content model independent of encoding, allowing for the support of various encodings;
—     provides a basis for national and regional profiles;
—     enables the combining of land administration/georegulation information from different sources in a coherent manner.
The following are outside the scope of this document:
—     interference with (national) land administration/georegulation laws with potentially legal implications due to the possibility of describing different types of systems but in the same notation;
—     construction of external databases with party data, address data, land cover data, physical utility network data, archive data and taxation data. However, the LADM provides stereotype classes for these data sets to indicate which data set elements the LADM expects from these external sources, if available.
This document provides the concepts and basic structure for standardization in the land administration/georegulation domain. It defines a general schema that permits regulatory information to be described. It also allows for the relationship to multiple parties and groups to be expressed together with a referencing structure so that sourcing of all information systems can be maintained. This document establishes the common elements and basic schema upon which more detailed schema can be established.

Adressierung - Teil 2: Zuweisen und Verwalten von Adressen für Objekte in der physischen Welt (ISO 19160-2:2023)
SIST EN ISO 19160-2:2024

This document focuses on assigning and maintaining addresses that allow the unambiguous determination of an object in the physical world for purposes of identification and location in the context of public administration and public service delivery. During assignment, an address is first associated with a particular object in the physical world. During maintenance, the address changes, for example, it is re-assigned to a different object, one or more of the address components are modified (e.g. a street name change), or the address is retired when it is no longer used. This document:
a)       specifies a good practice for assigning and maintaining addresses and address data; and
b)       specifies a governance framework for assigning and maintaining addresses and address data.
Very often local governments (e.g. municipalities) are assigned the mandate for the planning, implementation, evaluation and ongoing maintenance of addresses, and they are often supported by other organizations, such as the national government, a postal agency, private sector companies and national or regional organizations. This document is applicable to all organizations who have an interest, role or responsibility in address assignment and maintenance, for example in terms of:
—     developing legislation, policies or regulations for addressing;
—     facilitating and coordinating the naming of address components (the constituent parts of an address) and announcing and communicating these names;
—     installing address component signs in the physical world;
—     designing and implementing business processes related to address assignment and maintenance;
—     designing, implementing and maintaining access to address data;
—     developing software to facilitate the above; and
—     using addresses.

Geographic information - Metadata - Part 3: XML schema implementation for fundamental concepts (ISO 19115-3:2023)
SIST EN ISO 19115-3:2024

This document defines an integrated XML implementation of ISO 19115-1 and ISO 19115-2 by defining the following artefacts:
—     a set of XML schema required to validate metadata instance documents conforming to conceptual model elements defined in ISO 19115-1 and ISO 19115-2; and
—     a set of ISO/IEC 19757-3 (Schematron) rules that implement validation constraints in the ISO 19115-1 and ISO 19115-2 UML models that are not validated by the XML schema.
This document describes the procedure used to generate XML schemas from ISO geographic information conceptual models related to metadata. The XML schemas are generated directly from the conceptual UML model (8.5).

This document establishes a standard registration and maintenance mechanism for the registration of ISO 19150-4-conformant geographic information service ontologies.
This document makes use of ISO 19135-1 whenever appropriate.
This document does not define semantics operators or rules for ontologies, and does not develop any application ontology.
In relation to ISO 19101-1:2014, 6.2, this document defines and formalizes the following purposes of the ISO geographic information reference model:
—     geographic information service components and their behaviour for data processing purposes over the Web; and
—     OWL ontologies to cast ISO/TC 211 International Standards to benefit from and support the Semantic Web.
In relation to ISO 19101-1:2014, 8.3, this document addresses the Application:Procedural foundation of the ISO geographic information reference model.

Geographic information - Schema for coverage geometry and functions - Part 1: Fundamentals (ISO 19123-1:2023)
SIST EN ISO 19123-1:2023

This document defines a conceptual schema for coverages. A coverage is a mapping from a spatial, temporal or spatiotemporal domain to attribute values sharing the same attribute type. A coverage domain consists of a collection of direct positions in a coordinate space that can be defined in terms of spatial and/or temporal dimensions, as well as non-spatiotemporal (in ISO 19111:2019, “parametric”) dimensions. Examples of coverages include point clouds, grids, meshes, triangulated irregular networks, and polygon sets. Coverages are the prevailing data structures in a number of application areas, such as remote sensing, meteorology and mapping of depth, elevation, soil and vegetation. This document defines the coverage concept including the relationship between the domain of a coverage and its associated attribute range. This document defines the characteristics of the domain. The characteristics of the attribute range are not defined in this document, but are defined in implementation standards. Consequently, the standardization target of this document consists of implementation standards, not concrete implementations themselves.

Geographic information - Schema for coverage geometry and functions - Part 3: Processing fundamentals (ISO 19123-3:2023, Corrected version 2023-11)
SIST EN ISO 19123-3:2023

This document defines a coverage processing language for server-side extraction, filtering, processing, analytics, and fusion of multi-dimensional geospatial coverages representing, for example, spatio-temporal sensor, image, simulation, or statistics datacubes. Services implementing this language provide access to original or derived sets of coverage information, in forms that are useful for client-side consumption.
This document relies on the ISO 19123-1 abstract coverage model. In this edition, regular and irregular multi-dimensional grids are supported for axes that can carry spatial, temporal or any other semantics. Future editions will additionally support further axis types as well as further coverage types from ISO 19123-1, specifically, point clouds and meshes.

Geographic information - Observations, measurements and samples (ISO 19156:2023)
SIST EN ISO 19156:2023

This document defines a conceptual schema for observations, for features involved in the observation process, and for features involved in sampling when making observations. These provide models for the exchange of information describing observation acts and their results, both within and between different scientific and technical communities.
Observations commonly involve sampling of an ultimate feature-of-interest. This document defines a common set of sample types according to their spatial, material (for ex situ observations) or statistical nature. The schema includes relationships between sample features (sub-sampling, derived samples).
This document concerns only externally visible interfaces and places no restriction on the underlying implementations other than what is needed to satisfy the interface specifications in the actual situation.

SIST EN ISO 19157-1:2023

This document establishes the principles for describing the quality of geographic data. It:
—    defines a well-considered system of components for describing data quality;
—    defines the process for defining additional, domain-specific components for describing data quality;
—    specifies components and the content structure of data quality measures;
—    describes general procedures for evaluating the quality of geographic data;
—    establishes principles for reporting data quality.
This document is applicable to data producers providing quality information to describe and assess how well a dataset conforms to its product specification and to data users attempting to determine whether or not specific geographic data are of sufficient quality for their particular application.
This document does not attempt to define minimum acceptable levels of quality for geographic data. Such information is usually present as a requirement in a data product specification, defined in accordance with ISO 19131, for example.
