2.2 ISO/TC211

Data exchange
ISO does not standardise any exchange format but data exchange is addressed in
the ISO 19118 (Encoding). It recommends that an exchange format be built upon the
currently wide1y used Extensible Markup Language (XML). Also, ISO does not deal
with the technical details of transferring data between different hardware platforms.
The ISO 19118 only states that the application schema of the two systems between
which the data exchange takes place, must be alike. This simply means that a system
to which the tourism-GIS data may be transferred, has to provide the same feature
types: lake, wood, and beach, etc., and the same structural information. If the feature
types do not match, information is lost during the transfer. If, for example, in the
second system only one feature for traffic is available, then roads and hiking trails
would become the same feature and could not be distinguished from one another.
2.2.3 Reference model (ISO 19101)
Among geomatics specialists a consensus has emerged that the field of geographie
information is a specialisation within the Information Technology field. At the same
time, there is a growing recognition among users of Information Technology that indexing by location is a fundamental way of organising and using digital data. To
David McKeIlar is Canadian. He was born in
Glasgow, Scotland, and immigrated to Canada in

is with 12 Geomatics, Imagery & Counter Intelligence.
Mr. McKelIar is said to be the father of the
ISO/TC211 as he conceived and planned the establishment of this committee, thus serving the requirements of the international geomatics community, and the interests of Canada as weIl as of the
geomatics group ofNATO (DGIWG).
