Add Layer
The Add button opens the Upload Data window (Fig. 1). You may upload a table, raster or shapefile. 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.
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 the headers or names of each column. These must not contain any special characters or non-standard lettering (such as 'ü' or ð). Column names that are reserved and may not be used are: 'ID','long','date','time'.
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 (Raster)
Format: *.tif
Bands: At the moment only single-band rasters are allowed.
Size: max. 150 MB
Projection: currently the only valid projection is WGS84
Shapefile
Format: Only a compressed .zip file with all necessary files is valid (Figure 2)
Contents: The .zip file must contain a *.dbf, *.prj, *.shp, *.shx file each and can additionally contain a *.sbx and *.sbn file. The files have to be directly in the subfolder and must not be stored in a subfolder. Also no additional subfolder is allowed in the .zip file
Projection: currently the only valid projection is WGS84
