2.1 History of geomatics standards
29
resulted in a large number of standards, most of whieh are weIl known, but are rarely
related to the work of ISO and IEC. The following table lists the SCs that are relevant for computer graphics and geographie Information Teehnology and some ofthe
standards they have developed.
ISO/IEC JTCl/SC24:
Computer graphies and
image proeessing
ISO/IEC JTCl/SC32:
Data management and interchange
ISO/IEC JTCl/SC34:
Doeument deseription and
proeessing languages
GKS, GKS-3D, PHIGS, CGM, CGI,
PNG (Portable Network Graphies),
VRML (Virtual Reality Modelling Language),
BIIF (Basic Image Interchange Format)
SQLIMM (Struetured QueryLanguage/
MultiMedia)
SGML (Standard Generalized Markup L.),
HTML (Hypertext Markup Language)

Beginning of the standardisation of geographic information / geomatics
The Europeans have long established traditions in the development of standards
for eadastre, eartography, and environmental proteetion. Following in these traditions, the first projeet to standardise geographie information started in Europe in
1991. Led by AFNOR, the national standards body of Franee, the European standardisation organization CEN (Comite Europeen de Normalisation) ereated its Teehnieal Committee 287 (Geographie information). The work ofCEN/TC287 resulted in
eight European prestandards. The sueeessful eoneeptual developments were integrated into the larger body of ISO a few years later. The work of CENITC287 originally eontained a full range of nearly 20 standards. Faeing the upeoming establishment of ISOITC211 in 1994, and to avoid duplieate work, the CEN/TC287 eeased its
aetivities.
The following list identifies the eight European prestandards and the two CEN reports for geographie information. Their titles read as an abstract of the standards later
developed by the ISOITC211 (Geographie information / Geomaties). Many CEN
documents were used as draft standards of ISO and many of the CEN experts eontinued their work in the ISO/TC211.
Some of the above-mentioned prestandards had evolved into CEN standards before they were downgraded to CEN prestandards in order to avoid eompetition with
the ISO/TC211 results.
The demise of CENITC287 is not typical of CEN Teehnieal Committees. Sinee
the unifieation of the eontinent, the importanee of European standards in other subjeet areas has grown and standardisation is now a priority.
