STEP 6

STEP 6: ADD LAYERS AND SHARE YOUR PROJECTS TO THE POLICROWD COMMUNITY!

PoliCrowd provides some additional features which make it a powerful 3D participatory platform. First of all, users are able to add to the World Wind virtual globe whatever map layer which is publicly made available on the Web by companies and organizations (e.g. satellite imageries, orthophotos and historical maps). This provides users with the possibility to create customized map mashups. Registered users have also the right to save their map projects, which keep trace not just of active layers, but also the position (i.e. latitude, longitude and altitude) and the orientation of the point of view over the globe. Once a project is saved, it contributes at populating a project catalogue which remains available for the entire PoliCrowd community. Registered users can fully edit their own projects (overwriting them after saving), but they can also open and edit projects created by other users, provided of course that they save their own versions.
Finally, each geographic layer added by a user is stored into a layer catalogue, which remains available for the community. In accordance with what happens for projects, each layer is also owned by the user who added it to PoliCrowd. This allows registered users to maintain the full control on their layers, but provides at the same time the whole community with the ability to exploit new sources of geographic information.
