Poland's cities equiped with ortophotos and drones

Poland's municipal offices have been using orthophoto maps as a tool for tax arrears collection, Gazeta Prawna daily reported. Orthophotos are aerial photographs geometrically corrected so that their scale is uniform. Thanks to orthophoto maps, the local authorities can investigate the actual state in order to find unregistered properties and collect the property taxes. In years 2009-2014 Katowice city managed to collect additional tax worth PLN 2.3 million using the maps. As daily reported, almost all cities  in Poland has such tools at their disposal nowadays. What is interesting, the cities are interested in buying drones to measure pollution and some of them have already been in talks with manufacturing companies.
