Table

Make sure that your table meets the following standards:

Format: Only a semicolon delimited file ('*.csv') is valid.

Headers: the first line of the table is considered as headers, which have to be denoted correctly as described below. The names must not contain any special characters or non-stadard lettering (such as 'ü' or ð).

Required Columns: 3 columns (Index, Latitude and Longitude) are required.

- acceptable index column name: Index

- acceptable latitude column name: Latitude, Lat, Y, North, Northing

- acceptable longitude column name: Longitude, Lon, X, East, Easting

Make sure that the first data line (i.e. the second line of your table) is filled with numerical values and not left empty even if no measurement exists. Otherwise the whole column will be treated as a string and can not be used as numerical data.
