Abstract:
In March 2001 ISO TC 211 approved a project to develop an international standard: ISO 19130- Sensor and Data Models for
Imagery and Gridded Data. Since August 2002 when the project status was reported at the ISPRS Commission Il Symposium, the
project has made significant progress. The standard has been advanced from the working draft (WD) stage to the committee draft
(CD) stage. This paper discusses the current status of the ISO 19130 project, the content of ISO 19130 CD version 1, and the future
plan for both ISO 19130 and new remote sensing standards.
1. INTRODUCTION
ISO TC 211 is a technical committee under the International
Organization for Standardization (ISO). It is responsible for
setting international standards on geographic information [1]. In
March 2001, ISO TC 211 approved a new standard project for
setting an international standard on Sensor and Data Model for
Imagery and Gridded Data. The standard is designated as ISO
19130. The scope of the standard includes 1) specifying a
sensor model describing the physical and geometrical
properties of each kind of photogrammetric, remote sensing and
other sensors that produces imagery data; and 2) defining a
conceptual data model that specifies, for each kind of sensor,
the minimum content requirement and the relationship among
the components of the content for the raw data that was
measured by the sensor and provided in an instrument-based
coordinate system, to make it possible to geolocate and analyze
the data. Meanwhile, a project team, consisting of 37 experts
nominated by 16 ISO TC 211 national members and liaison
organizations, was formed to undertake the task of developing
the standard.
So far, the project team has produced five versions of the
working draft. The development status was reported at several
international conferences [2][3]. Since this standard is a
member of the ISO 19100 series of standards, during the
development of the standard the project team has worked
closely with other ISO TC 211 project teams, especially ISO
19115-2 Metadata - Part 2: Extensions for imagery and gridded
data [4] and Harmonized Model Maintenance Group
(HMMG)[5] to harmonize this standard with other standard.
The project team has also worked with Open GIS Consortium
(OGC)'s Sensor Model Language (SensorML) [6] team to
ensure the compatibility between ISO 19130 and SensorML
and to enable the use of SensorML as one of the
implementations of ISO 19130.
The project team submitted the latest version of working draft
to ISO TC 211 Secretariat on January 23, 2004 as the CD
version 1.0. This paper discusses the contents of ISO 19130

CD-1, and the future plan for both ISO 19130 and new remote
sensing standards.
2. THE COMMITTEE DRAFT VERSION 1 OF ISO 19130
Currently, the committee draft version 1 (CD-1) is the latest
draft of ISO 19130. It represents significant improvement over
Working Draft version 2 (WD-2) reported at [3]. The ISO
19130 CD-1 includes twelve normative clauses, one normative
annex, one informative annex, and an informative introduction.
For Clauses 1-5, there is no significant change from WD-2 to
CD-1. The most significant changes and reorganization of the
standard have been taken place in Clauses 6-12. The following
subsections discuss those clauses.
2.1 Georeferenceable dataset (Clause 6)
This intention of this clause is to provide the overall view of the
standard and a top level UML model (figure 1) to show how
each classes defined in the standard can be assembled together.

As. shown in ‘Figure 1, ISO- 19130 . deals | with
SD GeoreferenceableDataSet class. All classes defined in ISO
19130 have a prefix SD. A georeferenceable dataset is defined
as a geospatial data product that is not georectified but contains
sufficient geolocation information so that the georectification
process is possible. ISO 19124 review summary discussed the
concept of the georeferenceable dataset [7], and the ISO 19101-
