I've few questions regarding CSV and OGR field types: Doc. http://www.gdal.org/ogr2ogr.html mentions following field types for "-mapFieldType": Integer, Integer64, Real, String, Date, Time, DateTime, Binary, IntegerList, Integer64List, RealList, StringList.
Doc http://www.gdal.org/drv_csv.html says: << Limited type recognition can be done for Integer, Real, String, Date (YYYY-MM-DD), Time (HH:MM:SS+nn), DateTime (YYYY-MM-DD HH:MM:SS+nn) columns through a descriptive file with the same name as the CSV file, but a .csvt extension (...) Starting with GDAL 2.0, subtypes can be passed between parenthesis, such as "Integer(Boolean)", "Integer(Int16)" and "Real(Float32)" << Questions: 1. How is 'binary' encoded? E.g. when defining binary in a CSV file, how is it encoded? Hex? 2. Can a field in a CSV input files have a IntegerList or a Binary? 3. What is the value delimiter in a field of type IntegerList, Integer64List, RealList, StringList? 4. "Boolean, Int16, Float32" are mentioned as subtypes. Are there more subtypes? -S. _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
