4  What is the ISO Geodetic Registry?

The ISO Geodetic Registry is a structured database of coordinate reference systems and transformations that is accessible through an on-line registry system.

This Registry is provided under the auspices of ISO Technical Committee 211 on geographic information/geomatics and conforms to ISO standards:

Users of the Registry may query and view data and generate reports via anonymous guest access. Registered users may also submit proposals for new additions or clarifications to the Registry.

5  Getting started

5.1 The Registry website

The ISO Geodetic Registry defines the following roles:

Table 4 — Roles in the registry


Submitting organization

Organization authorized by a register owner to propose changes to the content of a register (ISO 19135:2005)

Control Body

Group of technical experts that makes decisions regarding the content of a register (ISO 19135:2005)

Register Manager

User/organization to which management of a register has been delegated by the register owner (ISO 19135:2005)

Register Owner

User/organization that establishes a register (ISO 19135:2005)

Point of Contact

The Point of Contact is an organization-related role and gives a user the right to delegate the roles held by his organization to other users of his organization.


Administrators have the right to manage registers, organizations and registry users. An administrator assigns register roles to organizations. The administrator role is global and not connected to a specific register or organization.

Roles are assigned to organizations only but may be delegated to affiliated users by the organization’s Point of Contact user. Users who were delegated a role may subsequently act on the organization’s behalf.

7  Submitting proposals

The content of the registry is complemented and updated by the submission of proposals by submitting organizations. There are four types of proposals that may be submitted to a register (ISO 19135:2005):

Table 5 — Proposal types

Type Description


Addition is the insertion into a register of an item that describes a concept not described by an item already in the register.


Clarifications correct errors in spelling, punctuation, or grammar. A clarification shall not cause any substantive semantic or technical change to a registered item.


Submitting organizations may submit requests for retirement of registered items that are no longer useful for producing data. Retirement is accomplished by leaving the item in the register, marking it retired, and including the date on which it was retired.


Modification of a registered item that results in substantive semantic or technical change. A supersession is accomplished by including a new item in the register with a new identifier and the date on which it superseded the original item. The original item remains in the register but includes the date at which it was superseded and a reference to the item that superseded it.

7.1 Prerequisites

To submit new content to or to update existing in the ISO Geodetic Registry, the following preconditions must be fulfilled:

  1. You have created a user account (in the process you have either joined an existing organization or created a new one) and are logged in,

  2. your organization was assigned the Submitter role by the registry administrator, and

  3. the right to act as a I was delegated to you by the Point of Contact of your organization (if you created the organization, you automatically become your organization’s Point of Contact).

If these preconditions are fulfilled, you will see additional action buttons when browsing the registry content.

7.2 Submitting new content

To create an addition proposal, browse to the register content by clicking on the register name or on one of the contained item classes in the application menu and subsequently press on the button displayed above the register content.

If the list of register item contains only items of a single item class, clicking will lead you directly to a proposal form for this item class. Otherwise you must select the item class of your proposal in the following screen.

Mandatory fields of the proposal are marked with the icon. If you omit to fill out a mandatory field, an error message will be displayed and the omitted fields are highlighted in red once you try to save or submit the proposal. Please note that the omitted field need not necessarily be in the current tab or accordion pane. If you are unsure why an error message is displayed, make sure to check all tabs and accordion panes for omitted mandatory fields.
