Replace CSV with more efficient Parquet file format or add Parquet as second file format.

I'm playing with Jupyter Notebooks / Pandas and recently discovered the Parquet file format. It has many advantages over CSV. It would be nice to get the data from the site in bulk using that format.

Strategies to get complete area coverage ?

Hi,

do you have sample flyer that we could distribute to recruit more people for the project ?

If we could get a few taxi drivers on the project we could quickly get complete area coverage in cities.

Number of Wifi access point records

Hi,

it's 2 147 483 647 so it's maximum value of a signed 32 bits integer.

Would it be possible to use a storage system allowing 64bits IDs and more than 2 147 483 647 records ?
