Large Scale Topographic Maps Generalisation and Visualization Based on New Methodology

Integrating spatial data from different sources results in visualization which is the last step in the process of digital basic topographic maps creation. Sources used for visualization are existing real estate cadastre database orthophoto plans and digital terrain models. Analogue cadastre plans were scanned and georeferenced according to existing regulations and used for toponyms. Visualization of topologically inspected geometric primitives was performed based on the ‘’Collection of cartographic symbols for scales 1:500 and 1:2500’’ – regulations applied in Republic of Croatia, since Federation of Bosnia and Herzegovina does not have prescribed regulations. In addition to integrating different spatial data, it is necessary, prior to the visualization step, to perform the generalization step (depending on basic topographic map scale, partial or complete generalization is applied). This paper describes the process of generalization and visualization of data collected and processed in accordance with the topographic data model from the Federal Administration for Geodetic and Property Affairs.
