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

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.

Information géographique - Schéma de la géométrie et des fonctions de couverture - Partie 3: Principes de base du traitement (ISO 19123-3:2023, Version corrigée 2023-11)

Le présent document définit un langage de traitement de couverture pour l'extraction, le filtrage, le traitement, l'analyse et la fusion côté serveur de couvertures géospatiales multidimensionnelles représentant, par exemple, des cubes de données spatio-temporelles de capteurs, d'images, de simulations ou de statistiques. Les services mettant en œuvre ce langage permettent d'accéder à des ensembles originaux ou dérivés d'informations de couverture, sous des formes utiles pour la consommation côté client.
Le présent document s'appuie sur le modèle de couverture abstrait de l'ISO 19123-1. Dans le présent document, les grilles multidimensionnelles régulières et irrégulières sont prises en charge pour des axes qui peuvent avoir une sémantique spatiale, temporelle ou autre. Les éditions suivantes incluront aussi d’autres types d’axes et d’autres types de couvertures provenant de l’ISO 19123-1, spécifiquement, les nuages de points et les maillages.

Geografske informacije - Shema za geometrijo podatkovnega sloja in funkcije - 3. del: Osnove obdelave (ISO 19123-3:2023)

Ta dokument določa jezik obdelave podatkovnega sloja za strežniško pridobivanje, filtriranje, obdelavo,
analitiko in združevanje večdimenzionalnih geoprostorskih podatkovnih slojev, ki na primer predstavljajo prostorsko-
časovne senzorične, slikovne, simulacijske ali statistične podatkovne kocke. Storitve, ki uporabljajo ta jezik, zagotavljajo dostop do izvirnih ali izpeljanih nizov informacij o podatkovnih slojih v oblikah, ki so uporabne za odjemalca.
Ta dokument temelji na abstraktnem modelu podatkovnega sloja iz standarda ISO 19123-1. V tej izdaji so podprte pravilne in nepravilne večdimenzionalne mreže za osi, ki lahko vsebujejo prostorski, časovni ali katerikoli drug pomen.
Prihodnje izdaje bodo dodatno podpirale dodatne vrste osi in dodatne vrste podatkovnih slojev iz standarda ISO 19123-1, zlasti oblake točk in mreže.
