Over the course of several years, web cartography which changed the way of presentation and exchange of information gained new sense. Techniques development and availability of geoinformation tools in connection with net data transfer new quality enabled to create maps accessible in real time according to user’s preference. The aim of the paper is to characterize and evaluate technique of parameterization for net resource URL address (Uniform Resource Locator). Examples of maps presented in a browser’s window according to set parameters defined in accordance with rules in force in the range of API programistic interfaces of chosen map services were presented in the paper. Maps developed by URL link parameterization technique were put to functional tests. Moreover, efficiency and utility tests were performed. Performed tests show that creating maps with help of discussed technique needs knowledge and expert abilities which may cause difficulties to less advanced users and its use allows to evoke maps in the browser’s window but in the limited range.
