The existing literature broadly discussing the advantages of the dasymetric mapping method over other existing methods of cartographic visualization of population density, such as a choropleth map. Despite the wide popularity of the dasymetric mapping method, all currently known tools for dasymetric maps production are implemented as extensions for commercial desktop GIS or as standalone desktop applications, which limits their usability for novice users. In this paper, the practical aspects of developing a web application for creating and publishing dasymetric maps in a web environment will be discussed. The web application implements two-dimensional and three-dimensional methods of dasymetric mapping(K. Lwin, Y. Myrayama 2009). The server part of the application is developed in Python and Pandas, and the client part using HTML / Javascript using the Leaflet web-mapping API.
