- List of province symbols (*3):

- Regulations on station symbols, measurement parameter symbols (*4)

Note: (*) are information that shall not be changed over time. All values in the JSON sent back are of type String (string) except for GiaTriDo which is of type Double (floating point number). Water resource exploitation and utilization facilities shall not transmit duplicate data to the monitoring system.

5. Automatic data transmission through the FTP protocol:

a) FTP Option 01: One monitoring station transmits one measurement parameter:

Each time a monitoring station transmits data to the system (FTP Server) via one text data file according to the following standard:

- Data file name: MaTinh_KyHieuCongTrinh_KyHieuTram_ThongSoDo_ThoiGianGui.txt

- Content of the data file: Consists of multiple lines, each line separated by a TAB character (\t) or a comma (,);

- Example:

+ Data file name

HCM_nhamayheinekenVN_Gieng01_LUULUONG_20210214093230.txt

(Data file on water flow from well 1 of Heineken Vietnam Brewery in Ho Chi Minh City, transmitted at 9:32:30 AM on February 14, 2021);

+ Content of the data file:

b) FTP Option 02: One monitoring station transmits multiple measurement parameters:
