3. The Structure of the State Land Service of Latvia

4. Characteristic on present situation
unarranged legislation;
lack of qualified personnel – Latvian education system does not prepare students of essential profile;
lack of financial resources – shortage of necessary finances for qualitative maintenance of graphical databases;
sharp rise in development of GIS technologies – facilating the complexity of job versus need for more qualified personnel;

5. Characteristic on present situation (continued)
standardization for geographical data, data exchange, data processing etc is not yet performed;
establishing of common data management principles is weak. Also there is imperfection of coordination between SLS regional structures;
data integrity losses – data duplication, failure in merging analogous datasets;
lack of experience in the advanced stage of data maintenance;
responsibility for data maintenance is divided between SLS regional offices.

6. the need for an unitary GI system within our organization
GIS project
As the result of the present situation analysis is the fact that we acknowledge
the need for an unitary GI system within our organization
On the 2 of April we have started the development of the GIS infrastructure within SLS

7. The purposes of GIS project
to produce base conception for unitary GIS (2001)
to develop a basic Metadata structure
to develop a centralized publishing system
to develop a Cadastral IS based on mentioned conception (2002)
to develop a Geodetic IS (2003)
to produce detailed conception for unitary GIS (2002 – 2010)
