This glossary gives explanations on words and abbreviations used in this document in the context of our web services.

For a more generalised GIS glossary please refer to the following links:

basemap

An image service with one layer of imagery, having one year of imagery in one location.

built-in named user account

The ArcGIS Enterprise portal can be configured to allow members to easily create accounts and groups in a portal. A named built-in account allows external to the LANDS network users to be added to an external organisation’s security group in order to get access to restricted web services in Spatial Portal.

Refer to https://enterprise.arcgis.com/en/portal/10.7/administer/windows/about-configuring-portal-authentication.htm

built-in proxy user account

The ArcGIS Enterprise portal can be configured to allow members to easily create accounts and groups in a portal. A proxy built-in account allows internal and external to the LANDS system administrators to automatically authenticate web service requests to and from their systems.

Refer to ESRI resource proxy

built-in system user account

The ArcGIS Enterprise portal can be configured to allow members to easily create accounts and groups in a portal. A system built-in account allows internal and external to the LANDS system administrators and non_ESRI users to be added to external organisations' security groups in order to get access to restricted web services in Spatial Portal.

Refer to https://enterprise.arcgis.com/en/portal/10.7/administer/windows/about-configuring-portal-authentication.htm

dynamic

Non tile-cached (https://qld-resources-spatial-data.atlassian.net/wiki/spaces/img/pages/62587288/Glossary#Tile-cached )

elevation service

ESRI proprietary ArcGIS Server web service that serves elevation imagery via a 32-bit mosaic dataset to allow for height values and rendering rules to be applied on the service.

Refer to Sharing lidar datasets

enterprise user account

The ArcGIS Enterprise portal is designed so you can use enterprise accounts and groups to control access to your ArcGIS organization. For the internal Queensland LANDS network control access to the portal is used to identity providers that support Security Assertion Markup Language (SAML) 2.0 Web Single Sign On.

Refer to https://enterprise.arcgis.com/en/portal/10.7/administer/windows/about-configuring-portal-authentication.htm

image service

ESRI proprietary ArcGIS Server web services that serves imagery via a 8 or 16-bit mosaic dataset.

Refer to Key concepts for image services

ND

Natural Disaster

OGC®

Open Geospatial Consortium is an international voluntary consensus standards organisation. WMS, WMTS and WCS are included in their suite of OGC compliant web services.

Refer to OGC

Open Source

Open Source Geospatial Foundation (OSGeo) is a non-profit non-governmental organisation whose mission is to support and promote the collaborative development of open geospatial technologies and data. OSGeo projects include QGIS software.

Refer to OSGeo

Project

In the context of the image and elevation services, a project means the individual child mosaic dataset that is included in the parent mosaic dataset that is published as a web service.

QG

Queensland Government

QGov

Queensland Government

QGov user account

This is different to a built-in named user account in Spatial Portal. This is a self registered QGov account via the https://identity.qld.gov.au/login/login.html webpage that is being used to Sign In to the Spatial Portal after being added to your Organisation’s security group.

REST

Representational state transfer (REST) is an architectural style that allows ArcGIS Server to reveal a hierarchy of information about itself through endpoints, or URLs. When you use the Services Directory, you navigate through a series of links to discover information about the server. Each time you click a link, you see a new page that reveals additional information about what's available on the server. The information that you see on the page is retrieved through REST using the page's URL.

RESTful is typically used to refer to web services implementing such an architecture.

Refer to https://en.wikipedia.org/wiki/Representational_state_transfer and https://developers.arcgis.com/rest/services-reference/enterprise/using-the-services-directory.htm

REST Endpoint

The web address or URL for the REST web service. The REST endpoints are found in the image server’s ArcGIS REST Services Directory.

Refer to https://developers.arcgis.com/rest/services-reference/enterprise/using-the-services-directory.htm

SISP

Spatial Imagery Services Program

SSO

Single sign-on (SSO) is an authentication process that allows a user to access multiple applications with one set of login credentials. SSO is a common procedure in enterprises, where a client accesses multiple resources connected to a local area network (LAN).
SSO allows internal network users to be automatically signed in ArcGIS Or Entreprise QPortal or Spatial Portal.

Refer to https://www.techopedia.com/definition/4106/single-sign-on-sso

Static

See https://qld-resources-spatial-data.atlassian.net/wiki/spaces/img/pages/62587288/Glossary#Tile-cached

Tile-cached

A tile_cache stores a collection of images/tiles at various scales. A client can request the tiles needed to display a particular map extent faster than a dynamic service can. A service tile_cache can be disabled in ESRI clients so that the service becomes dynamic

Refer to https://developers.arcgis.com/net/uwp/api-reference/html/T_Esri_ArcGISRuntime_Mapping_TileCache.htm

time-series

Multiple years of imagery in one location

WCS

An OGC compliant Web Coverage Service (WCS)

The WCS capability is used in our Time Series elevation services to provide height information.

Refer to https://docs.qgis.org/3.16/en/docs/user_manual/working_with_ogc/ogc_client_support.html#wcs-client and https://www.winwaed.com/blog/2009/02/09/overview-wms-wfs-wcs/

WMS

An OGC compliant Web Map Service (WMS).

Refer to WMS and https://docs.qgis.org/3.16/en/docs/user_manual/working_with_ogc/ogc_client_support.html#wms-wmts-client and https://www.winwaed.com/blog/2009/02/09/overview-wms-wfs-wcs/

WMTS

A tile-cached a OGC compliant Web Map Tiled Service (WMTS). This is a faster and more efficient way of distributing data than WMS because with WMTS, the tile_cached tile sets are pre-generated, and the client only requests the transmission of the tiles, not their production.

Refer to https://docs.qgis.org/3.16/en/docs/user_manual/working_with_ogc/ogc_client_support.html#wms-wmts-client

WOS

Whole of State
