The availability, functionality and usability of interactive maps and digital representations of environment in Internet are on the rise. Their popularity results mainly form the technological progress and development of programming tools available as open source, and from the growing demands of users who are looking for specialist geoinformation services in Internet. The goal of this study is to analyse the possibilities of using chosen programming techniques and tools such as jQuery JavaScript components to creating interactive maps. JQuery was chosen because it is one of the most popular technology of making web applications. The analysis was possible thanks to tests of three web applications created on the basis of chosen scripts, available under open source licence. The research showed that jQuery library can be used to creating web map applications but in a limited scope.
