Raster map viewers can be used by various entities, including public administration units. They are used in particular when there is no economic justification for creating extended and comprehensive mapping services, or when there is a need to quickly publish the given map. These viewers can be made using one of many available components. However, not all of them are optimal for such applications. Selected raster map viewers may be inefficient, which may make it difficult or even impossible to view the map. The aim of the present work was to conduct a comparative analysis of the performance of selected raster map viewers. The prototype applications were used to test the implementation of selected designing tools. The efficiency measurement was made using tools for test automation. The value of the ESSCORE (Estimated Speed Score) synthetic performance meta-index has been determined. It has been shown that the application created with the use of the ImageViewer component (jQuery JavaScript) was objectively the best of the tests tested for the presentation of raster graphics (according to the adopted testing scheme).
