When uploading CSV files, keep the following in mind:

CSV files must be in UTF-8 encoding.

CSV files must contain coordinates (latitude and longitude) for points only or WKT (well known text) for points, lines or polygons.

CSV files must be comma (,) separated.

If a row of data is invalid, that row will not be included in the resulting tileset.

The first line of your CSV file must contain column headers.

• Latitude
• latitude
• lat
• y
• Longitude
• longitude
• lon
• long
• x
• WKT
• wkt

On import we will try to auto discover the types in each column (String, text, date etc.) 

To define column types a .csvt file can be used. The .csvt file has to have the same name as the .csv file it describes. It enables definition of the following data types: Integer, Real, String, Date (YYYY-MM-DD), Time (HH:MM:SS+nn) and DateTime (YYYY-MM-DD HH:MM:SS+nn) and geometry column types (WKT, lat, X, lon, Y). A .csvt file contains only one line and the types for each column have to be quoted and comma separated, e.g.

"Integer","WKT","String"

Precision can also be applied

"Integer","Real","String(500)"
