5- Register of the names of the new official maps sheets of the
Replublic of Croatia
For new Croatian map grids in the new Croatian projection terrestrial ref-
erent system (HTRS96/TM) the new nomenclature is assigned to each map
sheet. Nomenclature contains name of the sheet. The map sheet name is
used to make easier orientation of the map sheet in the space using the
name of the well known geographic objects (features), which is on the map
sheet. To choose the most appropriate name for the map sheet, criteria of
judging candidate toponyms are defined (Croatian Geodetic Institute
2008a, Hećimović and Štefan 2009). Compared are toponym and feature
elements as: importance of the geographical feature, usage of the similar
toponym, number of inhabitants for oikonyms, usage of toponym as the
name in old map sheets, etc.
The names are assigned to the new maps sheet in the scales 1:250 000,
1:100 000, 1:50 000, 1:25 000, 1:10 000 and 1:5 000 which covers the
Croatian territory (Croatian Geodetic Institute 2008b). Names are not as-
signed to map sheets of bigger, cadastral scales (e.g. 1:2000, 1:1 000 and
1:500) because in big scales are dominating micro toponyms, and it is hard
to find publicly well known toponym. Endonym of the dominant object
that is appearing on map sheet is assigned. Names have been independ-
ently determined in the scales: 1:250 000, 1:100 000, 1:50 000 and 1:25
000; e.g. independently are determined: toponym-250K, toponym-100K,
toponym-50K and toponym-25K. Because hierarchical structure of no-
menclatures map sheets names in the scales 1:10 000 and 1:5 000 are used
from the map sheets in the scales 1:50 000 or 1:25 000 in which the map
sheet is hierarchical layer.
The best-known geographic features are oikonyms (names of settlements).
They are therefore commonly used by naming map sheets. However, when
there is no any populated place (oikonym) on the map sheet or other
toponyms are dominant on the map sheet (e.g. mareonyms (names of fea-
tures connected to seas), oronyms (names of higher features, as muntains),
regionyms (names of regional features) etc.) this rule was not followed.

(object) and scales. Oikonym is the most dominant class. Croatia has rela-
