The paper deals some problems with the scale and the possible concepts development of national topographical data infrastructure. There are two concepts in the procedure of structuring and updating of topographical data in digital (vector) form: model stars (discrete) and model steps (continuous). The discrete model consists of some basic data of framework. So, each of those data is updated separately. The continuous model concerning to the fundamental geospatial (topographical) data and all other data are generated from one level to another, in different scales and contents. There are some positive and negative characteristics in both concepts development of topographical data infrastructure. The first concept is good in this moment, but in the future the second concept will be better. However, it is very important that high level of modelling and automatization of procedures, both concepts support good possibilities for making and updating of topographical data infrastructure. Also, some experiences are presented in creating of the new topographic map by automated cartographic generalization.

U radu se iznose neki problemi s mjerilom i mogući koncepti razvoja nacionalne infrastrukture topografskih podataka. U konceptu strukturiranja i održavanja topografskih podataka u digitalnom (vektorskom) obliku postoje dva osnovna koncepta: model zvjezdica (diskretni) i model ljestvica (kontinuirani) podataka. Diskretni model podrazumijeva kreiranje više osnovnih skupova geoprostornih (topografskih) podataka i njihovo održavanje. Kontinuirani model odnosi se na jedan osnovni (bazični) skup topografskih podataka i na osnovu njega izvođenje i održavanje (ažuriranje) svih ostalih nivoa ili skupova topografskih podataka, odnosno kreiranje skupova podataka različitih mjerila i sadržaja. Oba koncepta razvoja infrastrukture topografskih podataka imaju svoje prednosti i mane. Smatra se da je prvi koncept trenutno prihvatljiviji, a da je drugi koncept složeniji i ima veću perspektivu. Međutim, ono što je vrlo važno, a to je da uz veliki stupanj automatizacije i modeliranja pojedinih procesa, i jedan i drugi koncept pružaju mogućnosti novih kreiranja i održavanja podataka, odnosno izgradnju infrastrukture topografskih podataka. Također, prikazana su neka iskustva prilikom izrade nove topografske karte automatiziranom kartografskom generalizacijom.
