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.
Contents
Table
Format: Only semicolon delimited file ('*.csv') is valid.
Headers: the first line of file considered as headers
Coordinate Columns: Latitude and longitude columns are required.

Longitude column name: Longitude, Long, X, East, Easting are valid names for longitude.
NOTE:If the second line in the file contains null value (empty string) corresponding column considered to be of type string.
Example (VAR1 and VAR2 are arbitrary names)
| INDEX | LATITUDE | LONGITUDE | VAR1 | VAR2 |
|---|---|---|---|---|
| 1 | 10.1 | 10.1 | 1 | 2 |
| 2 | 15.01 | 15.01 | 2 | 0 |
Coverage
Format: Only one band *.tif format is valid. If coverage has more than one band only the first band is taken into account.
