Ground water level catalog

Ground Water Level Catalog – General Description

The catalogue is a variable in the Matlab format file and it is kept in a file MAT. The structure is array with named fields that can contain data of various types and sizes. In the file there is only one variable, the file name and variable name are optional. The format of ground water level catalog is made in the same manner as catalog of seismic events

The variable describing the catalogue is a vector of structures, consisting of fields:

• field – name of field in the catalogue (text value);
• type – type of field in the catalogue and way of showing the field (numeric value);
• val – column array of values. For the text the column is an array type cell with text fields. For the remaining value the column is a numeric column.
• unit – description of unit for individual data (text value).
• description – short description of the parameter (text value).
• fieldType – semantic meaning of the field. When some field values are similar/related then fieldType name is entered and for another case [] is entered.

The fundamental is a full catalogue i.e. the variable contains the definitions of all specified fields. When some field values are missing then for the numeric data NaN (not specified) is entered and for the text null [] is entered. In the fields "ID", "Time" and "MAC" values in all rows must be present.
