Outline Introduction Harmonisation Analysis methods
Vector methods Raster methods Combine methods
Test Area ‘ŐRSÉG’ Results Conclusions
Introduction Historical maps are become more valued They connect a lot of different field, such
as history, geography, ecology, managements, etc.
Their GIS analysis give much more knowledge, than traditional viewing
GIS AnalysisPossible, when comparable maps are
available
1. Geometrically
2. Thematically
Geometric harmonisation Control Points Control Lines Control Areas
Application of DEMs Point features – mountains Linear features – ridges and valleys Areal features – plateaus, lakes

Conclusions Harmonisation is very crucial DEMs can help in geometric harmonisation Inclusion of DEM can help to interpret the
changes
