A. You must have lat/long WGS84 coords in the dataset file and make sure they are selected in the Special Column area of the Data>Column Properties dialog. Make an Attribute Map and while this window is the current (active) window click the Export to Google Earth icon on right-hand toolbar. This will save the map as .KMZ file that can then be opened into Google Earth.
A: Make sure the dataset contains columns for Lat/Long WGS84 and these are set as the columns for Google Earth export in the Data>Column Properties dialog. Google earth requires spatial data to have this projection. If the wrong projection is used, Google Earth will either produce an error when trying to load the data or will display it in the wrong place.
A: Google Earth reduces point visibility for overlays with many points. Try zooming in further and see if the data points become visible. It may also help to make the sizes of the data points larger than 1 or 2 pt, which appear as very small dots in Google Earth.
A: The sample number is stored under the Placemark for each sample otherwise the number would be displayed at all times. To view the variable value, sample number etc, within Google Earth hold the cursor over the point of interest and left click on it. The values should display in a tooltip.
A: KMZ is the file format used by Google Earth. If you have Google Earth installed and double click on the *.KMZ file, the data will be automatically loaded into the Google Earth program and zoomed to the imported data location. Alternatively, open Google Earth and then open the KMZ file from within this program.
