Survey file upload restrictions
Surveys must be uploaded as tables in comma-delimited CSV files. Any other kind of file will not be parsed correctly by the system.
Regarding uploaded data, we only impose requirements on point coordinate columns:
- The CSV must have one column with a label starting with "lon" to indicate longitude (case-insensitive, e.g. "Longitude-WGS84") - if multiple columns match this requirement only the first one will be used
- The CSV must have one column with a label starting with "lat" to indicate latitude (case-insensitive, e.g. "Longitude-WGS84") - if multiple columns match this requirement only the first one will be used
- The coordinates of the points are excpected to refer to the WGS84 ellipsoid. If the point coordinates are defined in another coordinate system, the points will not be placed correctly on the map.
Any other columns in the CSV will be treated as information to be displayed with the points in Survey view.
