Clicking on Add will open the window below (Figure 1). Depending on your data format, you can upload a Table, a Raster or a Shapefile. You then need to select a Category (choose that is closest to your type of data, this is only required to store the layer). You can optionally provide a Description of your dataset. Finally select your file and click Upload.

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.

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.

Example Table (VAR1 and VAR2 are arbitrary variable)

Index Lat Lon VAR1 VAR2
1 28.4 87.6 1 2
2 27.9 87.5 2 0

Coverage

  Format: Only one band *.tif format is valid.
