KML (Keyhole Markup Language) is the data format used by Google Earth and Google Maps. Google maps has a published API, and supports a subset of the KML used by Google Earth. KML files can include both vector and raster data.
KML is an open standard of the Open Geospatial Consortium (OGC). KML can include both raster and vector data, and the file includes symbolization. KML files are like HTML, and only contains links to icons and raster layers.
A KMZ file combines the images with the KML into a single zipped file. KMZ files are better because the lossless compression decreases file sizes, although only slightly, and because they make it impossible to separate and lose required image files. Even if someone tells you they want a KML file, you should send a KMZ. This saves you from separating the images from the KML file, and saves you the blame when the recipient separates them.
Before you start exporting maps to Google Earth, you should clean out the "My Places" and "Temporary Places" folders in Google Earth. Right click on each folder and pick "Delete Contents". Delete any layers you export and do not want; otherwise you are likely to wind up with a very disorganized mess of layers. In Google Earth you can rename layers by right clicking on them; you can changes the symbols by right clicking, and picking properties, and then "style, color".

Display of KML exports will only work if you have installed Google Earth, or another program that can display KML/KMZ files, and associated that program with KML/KMZ file extensions. MICRODEM is designed for personal home use and educational use, for which Google Earth should be free. Commercial use of Google Earth will likely require paying for a license.
KML export options can be set on Web tab of options form, brought up from Options program menu selection.
