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 Analysis Possible, 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

Application of DEM 1st Military and peaks Control Points – Mountain peaks Control Lines - Valleys

Application of DEM 2nd Military and peaks Control Points – Mountain peaks Control Lines - Valleys

Application of DEM 3rd Military and peaks Control Points – Mountain peaks Control Lines - Valleys

Application of DEM SRTM DEM and peaks Control Points – Mountain peaks Control Lines - Valleys

Application of DEM SRTM DEM and peaks Control Points – Mountain peaks Control Lines – Valleys valleys from 1st Military

Thematic harmonisation Reclassifying tables Universal Unambiguous Hierarchic … to 9 categories

Classic analysis methods Vector analysis Polygon overlay Forward Backward Raster analysis

Complex methods Inclusion of DEMs Profile based Area based Inclusion of other data

Focus Area ŐRSÉG

Results – overlay of vectors

Results – raster analysis 3rd 1st

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