Abstract: The disadvantages of existing topographic map up-dating used within the Czech Army Forces. The proposed method provides for objective ageing determination of single 1689 sheets of topographic maps in scale 1:25 000 by assessment of topographic map graphical tilling by means of reference graphical etalons and by means of calculated correlative relation between the graphical tilling and number of changes (maps ageing), From the last 3 up-datings of 96 representative topographic maps in scale 1:25 000, the number of changed map contents elements was assessed and correlative relation was calculated. Similarly, on the basis of topographic map in scale 1:25 000 also in scales 1:50 000, 1:100 000. 1:200 000 ageing was specified.
