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

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

changes
