  2. UNVT is a FOSS4G components The United Nations Vector Tile

    Toolkit (UNVT) is a collection of Open Source Software (OSS) to produce, host, style and optimize vector tiles for web mapping.
  3. UNVT Portable is a package for RaspberryPi that functions as

    a map hosting server and can be freely accessed from a web browser
  4. Build datasets based on OpenStreetMap, pre-installed with other tiled datasets,

    drone aerial data, shelter and hazard map data Web maps can be viewed in an offline environment during a disaster.
  5. Hosting using open software such as Nginx. Wi-Fi access point

    controlled by NetworkManager. Web Map Library based on MapLibre GL JS. Everything is composed of open source.
  6. By scanning the QR code with your phone's camera, you

    can view a web map even in an offline environment. No special skills or tools are required
  7. Uses RaspberryPi, so it can be mass-produced in preparation for

    natural disasters. Low cost and high performance

  15. • Clustering should be used since it is convenient for

    users to navigate through the map. Images should be visible on the map; on smaller zooms, they should be gathered in clusters;
 • The upload form should be easier to fi ll. We need to give some clari fi cations for fi elds that are not so obvious while fi lling them, decrease the number of fi elds to fi ll in, add pre fi lling function, and add drag & drop space for images;
 • Provide an opportunity to get the link of the present map extent (several imagery datasets as TMS/ WMTS link);
 • Users should be able to focus to AOI in three ways: via geocoder, drawn or loaded polygon. This enables data search inside selected boundaries.
 • Users fi nd using the timeline comfortable, especially with applied time fi lters. It can be added to make the search for images by date more interactive. v2
