The "External" memory, in this case the SD card. any change is backed up/copied internally and the two are compared on a regular basis for file/data integrity. This data's protected with Garmin's CDP system. Internal memory that isn't computer-accessible, this is where waypoints/active log/routes/system settings live. I know there are limits to the number of routes that can be saved and the number of "Via Points" used in each saved route. Routes work best as a dynamic navigation tool, ever evolving/changing. This option will use some of the Active Log capacity which can impact your ability to record a new high resolution track. While nice, high res tracks are usually not necessary for navigation.ģ) Rename the 2351 point file "Active Log" before sending to the GPS where it will install into the GPS's Active Log area (10k points max). Surprising how useful and good a track filtered from 5k-10k points down to 500 can be. The solution is to (using MapSource or other):ġ) Divide the 2351 point track into 5 tracks of 500 points or less.Ģ) Filter the 2351 point track to a single track of 500 pints or fewer (save with a new name to keep both). When loading a 2351 point track for example it is loaded as a saved track and is either filtered (full length, less resolution) or truncated (shortened) to 500 or fewer points. The "Archived Log" is a file a day as big as the card will hold which is a lot. Once you've loaded your GPS data into Google Earth, you can edit the waypoint placemarks and track paths, and add more information about the waypoints and tracks in the balloons.Click to expand.If my memory is right on 60/76 units the "Active Log" can be up tp 10,000 points, saved tracks (20) can be up to 500 points each. The file is imported and can be viewed and saved as KML in Google Earth as described below. Also, choose to Create KML LineStrings, and to Adjust altitudes to ground height.Ĭlick OK.

Read the instructions that came with your GPS device for exporting data from your device to a file on your computer. Also, if you have a GPS device for which Google Earth does not support direct connections, but which can export data to a file, you can still view your GPS data in Google Earth. If you have GPS data stored in a GPX or other type of file, you can open it in Google Earth. Before you disconnect your laptop from the internet and go out in the field, be sure to use Google Earth to fly to and view the places you'll be visiting so that the relevant imagery is saved in the cache on your hard drive.You'll need to make sure that your GPS device is connected and streaming data using one of the supported protocols (NMEA is the most common). From the GPS Import dialog box, select the _ Real Time_ tab to see options for viewing live data. For example, if you go out in the field with your laptop, you can view your current location live on Google Earth. You can also get data from your GPS device in real time.or select the GPS device data in the Places panel, go to the File menu, and select Save Place As. Save your GPS data to a KML file by right-clicking on your GPS data folder in the Places panel, and selecting Save Place As. Simply select the GPS data in the Places panel, and click Play on the Time Controls. Help with importing GPS data from a file can be found below.ĭata imported from a GPS handheld device can be animated because it has time stamps (date and time) of when it was collected by the GPS device. Your data will be downloaded from your device directly into Google Earth, where you can view and save it as described below.įor this tutorial you can import and use the GPS_track_Save-the-Elephants.gpx file you downloaded earlier.
