![]() (You can only define a normal and a highlight (i.e. There is no style option to control the fading in any way. At least one point of the track is within the specified time range: In your case, it is the starting point of the track at 8:48:29pm, located at the arrow icon. An arrow marks the position at at the end of the selected time-span. Placemark has multiple time-stamps, and is partly out of the defined time range: faded display of the parts outside the time-range, full display of the parts within the time range. ![]() Placemark has single time stamp, and is completely inside the defined time range: displayed normally Placemark is completely out of the defined time range: not displayed. If your data contains timestamps, the time-slider is displayed, and you are to define a time range. With this in mind, have a look how Google Earth displays these (internally created) KML files: How time-stamped information is displayed in Google Earth However, it is not possible to generate a KML "track" which is stringed together by a series of small, time-stamped LineStrings, each one representing the small connection between two adjacent coordinate pairs. If you check Create KML LineStrings, GE creates a KML file which basically consists of two parts:Ī "Points" folder, which contains a series of placemarks, each one being of type with its specific single time stamp.Ī single placemark, which contains the complete track line but not any time stamp information. (This enables some advanced functionality like the interpolation of time/position information between points.) Create KML LineStrings (compatible to GE element with all the information like all time stamps and coordinates. ![]() Unfortunately, during the import of a GPX file, Google Earth offers very few options: The KML reference / standard is device-independent though.) (My desriptions are based on GE version 7. The import options of GPX to KML are quite restricted, and so is the style control of information with time-stamps. Your observation is a result of two limitations within Google Earth: ![]()
