Dolgozat címe: Cartographic representation of landforms using digital data sources, a comparative
study for an area West of Karlstad
Dolgozat/kutatás ismertetése:
Overview of potential problems in handling the data, particularly data quality issues related to cartographic
accuracy and generalisation. The means of portraying landforms by interpolating surfaces
from irregular point value databases and the concept of visualization is tested on 5 different landforms.
A qualitative rating of suitability of the interpolation algorithms is given meanwhile a quantitative
comparison of the interpolated databases is carried out by grid mathematics. An evaluation
of the suitability of the Swedish National Elevation Databases, data extracted from aerial photos
and databases obtained by field survey for describing medium sized landforms is included.
Tárgyszavak: geodetic references, data quality, accuracy, data conversion, interpolation, landuse
classification, visualization
