Uploading and Downloading Garmin Overlander Data

Download your Garmin Overlander waypoints, routes, and tracks to your computer

ExpertGPS can transfer Garmin Overlander waypoints, routes, and tracks through your computer's USB port. It only takes a second or two to download all of the data from your Garmin using ExpertGPS.

Upload new waypoints, routes, and tracks to your Garmin GPS

Transfer data back to your Garmin Overlander with a single click. Upload waypoints, routes, and tracks to your GPS and print a matching map out to take with you into the field. ExpertGPS even lets you upload Excel, Google Earth, CAD, and GIS data to your Garmin Overlander!

Maximize your GPS Memory

Your Garmin Overlander has limited storage space for waypoints, routes, and tracks. Once you reach that limit, your GPS can't hold any more data. Smart ExpertGPS users have figured out how to eke out every last bit of memory space on their Garmin GPS receivers. Before each outdoor adventure or visit to a project site, they use ExpertGPS to back up the contents of their GPS, and then clear the GPS data memory. They can then download as much data as possible onto their GPS (leaving some room for GPS data collection out in the field). When they get back, they use ExpertGPS to upload all of their Garmin waypoints, routes, and tracks onto their computer and save it. Once they've backed up the new data from their GPS, they can clear the memory again, keeping their GPS ready for their next trip.

Backup your Garmin Overlander waypoints, routes, and tracks

Backup your Overlander waypoints, routes, and tracks by using ExpertGPS to transfer them to your laptop or desktop computer. Now you've got a safe back-up of all of the important data on your Overlander, and use ExpertGPS to find and create new waypoints, routes, and tracks to download to your Garmin GPS. Before you update your Garmin Overlander firmware or install a custom basemap, Garmin recommends that you backup all of your GPS data. ExpertGPS gives you the peace-of-mind that your Garmin Overlander data is always safe.

Making Maps from your Garmin Overlander Data

Real 1:24000 USGS Topo Maps

View your Garmin Overlander waypoints, routes, and tracks over USGS topo maps and aerial photos. These are actual 1:24000 scale topographic maps from the US Geological Survey, giving you much more terrain detail than the maps that came with your Garmin.

Toggle between Topo, Aerial, and Color Orthophotos

Instantly switch between topo maps, aerial photos, and color urban imagery using the T, A, and U keys in ExpertGPS. This ability to toggle back-and-forth between several views of your GPS data is unique to ExpertGPS, and is one of its most popular features.

Give your maps a professional look

ExpertGPS comes preloaded with all the line patterns and cartographic styles you need to draw highways, railroad tracks, transmission lines, streams, and more. And the waypoint and track style editors let you create your own map symbols, change track colors, and customize exactly how your GPS and map data is drawn.

Boost your Garmin GPS data entry speed 500%!

Why waste time entering new waypoints on the tiny screen of your Garmin Overlander? ExpertGPS can do it 5x faster! Use the New Waypoint dialog in ExpertGPS to create new waypoints and POI listings for your Garmin GPS. As you type, ExpertGPS automatically suggests the best possible name for this waypoint on your GPS.

Calculating Area with your Garmin Overlander

Calculate Area (Acreage) using your Garmin Overlander

Calculate area with your Garmin Overlander. ExpertGPS automatically calculates the acreage of any parcel, field, or tract no matter how irregular, when you record the boundary with your Garmin Overlander or trace it over the maps in ExpertGPS. ExpertGPS allows you to calculate acreage in three different ways:
1. Calculate area by walking a perimeter with your GPS. ExpertGPS calculates the acreage enclosed by your Garmin Overlander tracklog.
2. Calculate area by marking GPS waypoints at the corners of a field or parcel. In ExpertGPS, connect those waypoints into a route, and the acreage is automatically calculated.
3. Calculate area by tracing over a map or aerial photo. Use the Track Tool in ExpertGPS to trace the property boundary or field, and let ExpertGPS calculate the number of square feet it encloses.

Garmin Overlander Waypoints and POIs

Maximize your Garmin waypoints

ExpertGPS lets you get the most out of the waypoints on your Garmin Overlander by making it easy to assign the best symbol and to give each waypoint a long, meaningful name (using a real keyboard, not the little controls on your GPS). Think about it:

Your Garmin Overlander can hold 1000 waypoints. Waypoints on the Garmin Overlander can contain up to 31 characters. Waypoint comments (notes) can contain up to 50 characters. How long would it take you to enter all of those waypoints by hand into your GPS? ExpertGPS will save you hours on this one task alone!

Add Photos and Notes to your waypoints

ExpertGPS lets you link a photo to any waypoint or POI and includes a built-in photo viewer. And you can add your own detailed description to any waypoint - store as much information as you need.

Prevent Data Entry Errors with ExpertGPS

GPS coordinates are easy to mis-type. Using the Waypoint Tool in ExpertGPS to create new waypoints reduces the chances of making a mistake when manually entering coordinates on your GPS. ExpertGPS takes care of all of the coordinate conversion and datum shifts when communicating with your Garmin Overlander, further reducing errors.

Create routes the easy way!

The Garmin Overlander can hold 50 routes, each containing up to 250 turns or stops.

You can spend hundreds of dollars on dedicated camera hardware and cables to geotag your photos. Or, you can do it for free, using ExpertGPS. ExpertGPS automatically matches up the timestamps on your digital photos with the times recorded in your Garmin Overlander track log. It just takes a few seconds when you get back to your desk to have ExpertGPS automatically geotag your photos.

Share your Photos on Flickr and Google Earth

Photos geotagged using ExpertGPS are 100% compatible with flickr.com, Google Earth, and any other geotagging software or Web site.

Batch-Edit your Photo Metadata

ExpertGPS lets you quickly view, change, or batch-edit your photo metadata. Select all the photos for the day, and quickly add the city, state, and location in which they were taken. Add and remove keywords and descriptions. View shutter speed, aperture, and other camera settings.

Revolutionize the way you collect data in the field

Still using paper forms, or typing data into your GPS piece-by-piece? With your digital camera around your neck, Garmin Overlander in your backpack or in your vehicle, and ExpertGPS back at your desk, you can gather data on the move. There's no need to mark waypoints as you collect data - just snap photos at each site. ExpertGPS can create geo-referenced waypoints for your report from each photo you took along the way, and attach your photos to each waypoint it creates.
