Morten Borrebrek is Norwegian. He studied surveying and photogrammetry at the
Agricultural University of Norway in As near
Oslo. For the longest time of his career Mr.
Borrebrek was affiliated to the Norwegian
Mapping Authority. He is presently the head
of the section Geographie Information Technology.
Mr. Borrebrek started his career with research on digital geographie information at
the Norwegian Institute of Land Inventory.
3.2 Basic standards
85
Those works were focused on business applications in relation to the new technology.
Mr. Borrebrek was involved in GIS standardisation almost from the beginning. Already in 1985 he was coauthor ofthe Norwegian GIS standard SOSI.
Later he belonged to the team that developed the European GIS standards
(CEN/TC287) and subsequently he also has been a member ofISO/TC211 from
the beginning. Even more, the Working Group 4 (Geospatial services) has been
convened from its first day by Mr. Borrebrek.
3.2.6 Portrayal (ISO 19117)
Originally, the graphie presentation of geographie information was strictly the
domain of cartography but has now also become an important section of geomatics.
The ISO 19117 (Portrayal) defines a schema to create graphie output for datasets and
metadata of the ISO 19100 family of standards. The scope of ISO 19117 does not include the standardisation of cartographic symbols.
According to ISO 19117, the cartographic symbolisation is kept separate from the
feature types of the dataset. The definition of the cartographic representation for a
feature is stored in a portrayal catalogue. Essentially the catalogue is a reference list
that relates each feature code that is used to identify different feature types, to an individual cartographic portrayal.
A portrayal rule determines, which symbol shall be selected for a given feature.
The rule may be simple such as a "black solid line" to portray a local road. Or a rule
may be sophisticated such as a "double dashed red line" to portray a major road that
carries 10,000 or more vehicles daily and that is maintained by the provincial govemment.
The ISO 19117 defines a two-step, rule-based approach to select agraphie representation for a portrayed feature type. In the first step, the available "rules" are tested
according to a given feature type and its accompanying parameters. In the second
step, the portrayal specification is retrieved in order for the rule to be found valid. A
rule may be written as the SELECT-statement of SQL (Structured Query Language)
