NEW GEOMETRIC SOLUTIONS FOR WEB MAP TOPONYM PLACEMENT

The paper gives an overview and proposed solutions regarding to the most common mistakes for toponym placement for the best known and most-used Web maps and GIS services where toponyms placement is not harmonized with the cartographic principles, cartographic visualization conditions or cartographic generalization rules. The problem is solved by use of geometry where toponym or toponym letters are approximated with rectangle and/or with rhombus for italic letters. In the end, we introduce the concept of predicting the path along which can toponym label be placed through simple geometry test for intersections of lines and rectangles. Approximations of words or single letters of a word with rectangles or rhombuses is offered as simple solution for web map label placement calculations in real time which makes it convenient for web maps.
