First and foremost, all datasets must abide by the terms and conditions listed in the Public Data Explorer. In particular, please don't upload data that violates the original provider's copyright.
In addition, there are a few quantitive limits associated with dataset imports:
- All datasets must be under 150MB in size (unzipped).
- Each user can have no more than 20 published datasets at any given time.
These limits may be relaxed on a case-by-case basis. If you have an interesting dataset or group of datasets that exceed the constraints above, please let us know.
