1. Data catalog: metadata visualization
Jari Korpi
Dept. of Real Estate, Planning and Geoinformatics

2. Goals Study the visualization possibilities of the metadata
Which kind of views on metadata are needed?
Which kind of visual solutions are possible for the selected elements?
Which are the roles of the metadata elements?
Which are the most essential metadata elements?
Give a suggestion for the visualization of datacatalog

2.1
predefined list (ISO 19115), see Table 2
The ISO categorization (also used in Inspire) may be too generic for MMEA that is targeted to environmental data only. One alternative is to use General Multilingual Environmental Thesaurus (GEMET).

from GEMET
The purpose of this element is to narrow down the topic. Could be also freely given (i.e. not limited to any ontology or thesaurus) but then a metadata element telling the origin of the keywords must be added.

Scale denominator
The denominator of the usable scale for the data. Gives information on the generalization level.

The field activates in case of vector data.
Geographic extent
The extent of the resource in the geographic space. There is option to choose "whole Finland", otherwise given as a bounding box expressed with westbound and eastbound longitudes, and southbound and northbound latitudes in decimal degrees, with a precision of at least two decimals.

All possible referent systems (or a subset of preselected ones) could be given in a drop down list. This would make the referent system information more precise.
Vertical reference system
Provides information about the vertical coordinate reference system to which the maximum and minimum elevation values are measured.

The national water forecasts - WSFS
No graphic

The national hydrological forecasting and real time monitoring system in Finland, called the watershed simulation and forecasting system (WSFS), has been developed in the SYKE. The WSFS is described in detail in The WSFS is used in Finland for simulation of hydrological cycle and for making real-time forecasts. The system simulates the hydrological cycle using standard meteorological data. The system is originally based on the HBV watershed model. The hydrological model simulates the whole land area of Finland, including cross-boundary watersheds, total of km2. The area is divided into about sub-basins, each of which is about km2.
