transbigdata.dataagg

transbigdata.dataagg(data, shape, col=['Lng', 'Lat', 'count'], accuracy=500)

Aggregate data to traffic zone

Parameters:

• data (DataFrame) – The origin DataFrame

• shape (GeoDataFrame) – The shape of the traffic zone

• col (List) – You can either choose to input two columns, i.e., [‘Lng’,’Lat’], or to input three columns, i.e., [‘Lng’,’Lat’,’count’]”, where count means the points count

• accuracy (number) – The idea is to first implement data gridding and then the aggregation. Here, the grid size will be determined. The less the size is, the higher the accuracy will have.

Returns:

• aggresult (GeoDataFrame) – Traffic zone. The count column is the output result

• data1 (DataFrame) – The zone-matched data
