  5. 5. Background & Purposes • The policy of Open Government and Open Data in cooperation with citizens must be met. To do so, administrators have an increasing need for GIS methods and local geographic information. • In this study, we used a low cost measurable tool kit and free-use online mapping visualization for official vehicles (mainly snow plow and checking road condition). • Our experimental plan provided equipment for the purpose of monitoring real-time situations and relaying geographical data to governments. 5 ➔ Verification of Open-source Cloud Mapping and Smartphone Application for Supporting Local Government

  20. 20. Issues • Utilization of the smartphone and Android application can be achieved and online mapping at low cost and on different types of vehicles. Also, we try to create time- space mapping on the cartodb. • However to challenges of data integrity and continuity, it was not at this time possible to make real-time data publicly available. • On the local government side feedback, it is possible to publish these data as open data, it was seeking to streamline inquiry correspondence to public services. • However, because it could not be measured continuously (battery and machine operation), it was not open data.
  21. 21. Conclusions & Feature Works • Originally, this information was intended to provide accountability (transparency) and reciprocity with regard to the policy of Open Government and Open Data for residents. • Future goals also include adjusting the smartphone application so that reports from government and/or residents (cf. Minneapolis, Chicago and Boston…). • In this way, we may achieve the desired cooperation between government and residents for collection and management of real-time geographical information. -> MORE EASY to USE and REALTIME VISUALIZATION
