The Add button opens the Upload data screen (Fig. 1). You may upload a Table (point), Coverage (raster) or Shapefile (polygon/point) file. Click Choose File to browse to your file. You must then select a Category (used for classification in the layer list) and may add a Description of your dataset. Click Upload when you are finished.

Data Upload


Table icon 70.png Table (point)

Make sure that your table meets the following standards:

Format: Only Excel files (*.xlsx) and semicolon-delimited files (*.csv) are valid. The file name may not contain any blank spaces.

Headers: The first line of the table contains the names of each data column. These names must not contain any punctuation or special characters, such as '?', '/' or 'ü' or any blank spaces and may not begin with a number. Column names that are reserved and may not be used are: 'ID', 'long', 'time', 'as'.

Required columns: Latitude and longitude columns are required.

  • Acceptable latitude column names: Latitude, Lat, Y, North, Northing
  • Acceptable longitude column names: Longitude, Lon, X, East, Easting

Make sure that the first line of data, i.e. the second line of your table, contains numerical values in every column and has no empty cells. Otherwise, the entire column with the blank cell will be treated as a string and cannot be used as numerical data. Likewise, if your numerical data contain a combination of float (decimal) and integer (whole number) data, make sure that a decimal value occupies the first line of data.

Example Table (VAR1 and VAR2 are arbitrary variables)

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

Coverage icon 70.png Coverage (raster)

Format: *.tif

Bands: Only single-band rasters are supported.

Size: max. 150 MB

Projection: The only supported projection is WGS84

Shapfile icon 70.png Shapefile (polygon/point)

Format: Only a compressed .zip file with all necessary files is valid (Fig. 2).

Contents: The .zip file must contain a *.dbf, *.prj, *.shp, *.shx file each and can additionally contain a *.sbx and *.sbn file. There may not be any sub-folders within the .zip file.

Projection: The only supported projection is WGS84.
