Centralized hub for open datasets
While open data has revolutionized the availability of data, some of the types are not compatible with other types due to time/map based standards. Furthermore, the open data may be scattered across different portals and difficult to locate. Plenar.io is a tool to help alleviate this problem and can be a resource to find data.
"Plenario makes it possible to rethink the way we use open data. Instead of being constrained by the data that is accessible and usable, let’s start by formulating our questions and then find the data to answer them. Plenario makes this easy by tying together all datasets on one map and one timeline—because in the real world, everything affects everything else."
