Capturing screenshots and data from Garmin GPS devices

The market of navigational products is cluttered with a multitude of manufacturers, solutions, and products. Historically, Garmin came out as one of the most popular manufacturers of portable handheld GPS devices.

While industrial and military consumers tend to use high resolution frame grabbers in order to capture the screen from advanced GPS devices with VGA outputs, this is not an option for those users that have small personal GPS receivers.

There are several ways to capture the screen of a Garmin GPS device for free:

1. Using xImage software supplied by Garmin. (last update in 2005)
2. Using G7ToWin software developed by Ron Henderson. (last update in 2008)
3. Using the DNR Garmin application written by the Minnesota Department of Natural Resources. (last update in 2008)

Due to the fact that there are a lot of different Garmin GPS models, not all software programs will work with all Garmin devices. The G7ToWin application also has limited functionality with Magellan GPS receivers. All of the software packages listed above are available as free downloads.

xImage

Installation of the xImage software is easy. Download the last release from here, launch the file, and follow the on-screen instructions. You can the launch the xImage application from the Garmin submenu in the Windows Start Menu. The GPS must then be connected via USB or serial port for the software to be able to locate it.

Follow these instructions in order to capture a screenshot from your Garmin GPS device. Remember that the GPS must be connected to the capturing computer at the time of the screen capture.

1. Connect your device to your computer.  Verify that you have selected the ‘Garmin’ I/O format on your GPS unit.  See your GPS unit’s owner’s manual for more information.

2. Open xImage and click Next.

3. After a few moments, your device should be listed in the Device Settings window.  If not, click Find Device.  xImage finds the connected device.  If you have multiple devices connected to your PC, select the desired device from the drop down list.

4. Click Next.

5. Select Get images from the GPS, then click Next.

6. Select ‘Screen Shot’ in the Image Type field.

7. Verify that the desired screen is currently displayed on your GPS.

8. Click Next.

9. Select the desired location on your PC, enter a file name for the screen shot, and click Save.  The screen shot is saved as a .bmp file on your PC.  xImage displays a preview of the screen shot.

10. Click Finish to close xImage.

NOTE: You can also click Back to return to a previous screen and perform additional tasks.

G7ToWin

Download G7ToWin from here and install by following the prompts. Once the software is installed and your GPS device is connected, the G7ToWin software will bring you to a main screen that displays all of the waypoints saved in the GPS.

From here, the “Get and Show Display Bitmap” option must be selected from the GPS menu. This takes a screenshot of what is currently being shown on the GPS and saves it to the local hard drive. As well, the Ctrl+D keystroke combination may be pressed to grab the GPS’ screen at any time.

DNR Garmin

DNR Garmin may be downloaded from here. This application was created by the Minnesota Department of Natural Resources for their internal use, but the department also released the software to the public as a free download. This software is designed for power users and has many advanced functions.

Once the software is instalelled and the GPS receiver is synchronized with the DNR Garmin software, taking a screenshot is as easy as going to the GPS menu, and selecting “Garmin Screen Shot”. The program will then prompt you for a location of where to save the screenshot .bmp file.

Conclusion

xImage, G7ToWin, and DNR Garmin are all capable of saving the contents of the Garmin GPS’ screen to a BMP file on the computer the GPS is connected to, whether it be through a USB or serial port. Note that it is not possible to capture a screenshot of the GPS device when it is not connected to a computer on which one of these software packages is installed.

Using this software, there is also no way to automate the capture proccess or have the GPS screen’s output captured as a movie. This would be useful for archiving or creating instructional videos, for example. If real-time and automated screen capture is required, then a device with a VGA or DVI output coupled with one of these frame grabbers would allow the user to have that functionality.

Jing Project

Jing Project is a free screen capture software package that is distributed online by Techsmith, the creators of SnagIt and Camtasia Studio. It is available for Windows and Mac OS X.

Jing takes screenshots or video of your screen and then stores them or uploads them. Jing is also able to record voice from the computer’s microphone input while videos of the user’s screen are being recorded.

This critical review will look at this piece of software to try to determine its usefulness and functionality.

Installation

If installing on a Windows machine, Jing will prompt you to install .NET Framework 3.0, if you do not already have this installed. At the end of the installation, Jing will ask you to create a username and password. The software will not work without the creation of this account.

The software will start as soon as it is installed. You will notice a small yellow semi-circle at the top of your screen. Dragging your mouse over it will reveal Jing sharing options.

Recording

Start by dragging your mouse over the yellow bubble and then clicking on the capture crosshairs.

You will now be able to select what area of the screen is to be captured/shared.

Notice how a rectangular option window pops up in the lower left corner. This allows you to choose the capture format (image or video).

After the video or image is recored, Jing will show a preview (if it is a video) and will prompt the user as to what to do with the recording.

Unfortunately, Jing Project is only able to save the video as a flash .swf file, which means that there are no easy ways to share the recorded content. SWF flash files are great for webmasters who would like to post the recording to their site, but video sharing sites such as YouTube, Veoh, and others do not accept this as an upload format. For many, this makes the saving feature quite useless. The recording that was made via the Jing save feature is shown below:

Note that scrolling was very slow, meaning that the capture rate of Jing project is only a few frames per second. The image resolution, on the other hand, was exactly the same as the capture. Jing does not provide the user with an option to resize the output, which makes embedding high resolution flash videos into websites a pain. The video above had to be cropped on both sides due to the fact that the width of the recording made by Jing Project was unable to accommodate the width of the actual webpage.

Screencast.com Functionality and Review

The other thing about Jing Project is that it gives you access to Screencast.com, TechSmith’s content sharing portal. Think of it as a YouTube-like site for people sharing their captures. Clicking on “Send to ScreenCast: URL” will automatically upload the recording to the ScreenCast account that you signed up for earlier. Once the upload is finished, Jing Project will automatically paste the URL of your uploaded video into the Windows clipboard. You must paste it into a browser (press Ctrl + V) to reveal the link.

This is the capture that was made by ScreenCaptureNews.com: http://screencast.com/t/lCZwmjS5. Notice how there are no options to embed or share the video (like on popular video sharing websites such as YouTube or Veoh). Another disappointment is the fact that there is no option anywhere that will allow you to resize the video being viewed from its original size. This means that your audience must have monitors of your size or bigger in order to be able to view the recording in all its size and glory.

In fact, even a video of the same laptop screen did not fit into a full browser window when later being viewed on the laptop that was used to make the recording.

There is one thing to be happy about, however. Even though it looks like ScreenCast.com is an oversimplified and not fully worked out website, the absence of advertising (except for ScreenCast themselves) is always a welcome thing for a free product like Jing Project.

The Verdict?

Jing Project is an easy to use software with a very clean and intuitive interface. It does a pretty good job at capturing the area of the screen that it is told. The user is also given the option to record voice over the recorded video using a microphone. This, however, is where the good ends and the bad begins.

Videos can only be saved locally as an SWF file, which severely limits the user in options as to where to upload the video. Of course, the user can always use a 3rd party software to convert the SWF video to a format like AVI, but that complicates the proccess.

What’s more, the ScreenCast.com player is just that – a simple player. There are no options for the viewers to resize the resolution of the recording to fit the screen, and our tests showed that a bigger screen (or a higher resolution) is required to properly view a screen capture uploaded to ScreenCast.com. There are also no visible options for sharing or embedding, although this has become a standard amongst today’s content sharing websites.

The Jing Project seems like a piece of software created by TechSmith in order to get users that require more functionality to look into their other products. Specifically, Camtasia Studio, a $300 software program that pretty much extends Jing Project’s functionality and is also made by TechSmith.

Overall however, Jing Project is a decent software for those wanting an easy way to share their screen contents and store them without paying a cent. At the same time, those users that are serious about webcasting the content of their computer monitors are advised look elsewhere.
