This app returns either a space-time KML file or a space (location only) KML file, depending on the number of columns of data provided in the source CSV file.
To create a space-time KML file suitable for display using Google Earth the input *.csv file should consist of four named columns: oid (object identifier, numeric), edate (date of event, DD/MM/YYYY), lon (longitude in decimal degrees, numeric), and lat (latitude in decimal degrees, numeric). Typical input data would be as follows:
oid edate lon lat
1, 8/11/1967, -3.0332, 52.9052
2, 8/11/1967, -3.0198, 52.9035
3, 1/11/1967, -3.0985, 52.8983
4, 11/11/1967, -3.0628, 52.8986
To create a space (location only) KML file suitable for display using Google Earth the input *.csv file should consist of three named columns: oid (object identifier, numeric), lon (longitude in decimal degrees, numeric), and lat (latitude in decimal degrees, numeric).
