GPS-enabled smartphones make it easy to get directions, weather, and many more location based services since they automatically know where you are.  With Geosense, you can bring this functionality to any Windows 7 computer even if it doesn’t have a GPS chip.

Windows 7 introduced the new Sensors and Location platform that would let Windows automatically respond to environmental changes sensed by light, orientation sensors, or GPS chips.  This makes your computer more aware of its surroundings and enable it to change itself accordingly.  The location platform is especially interesting, as it brings the potential of automatic location based search and maps to your PC.  Unfortunately, most laptops today are not equipped with GPS chips.  Thanks to Geosense, however, you can still use the location platform.

Geosense uses IP lookup, Wi-Fi and Cell tower triangulation, and more to find your location as accurately as possible.  Geosense lists itself as a sensor in the Windows Sensors and Locations, so once you’ve installed it, all location-aware applications and services will be able to pick up your location from it.  Please note that Geosense only works on Windows 7 Home Premium and higher, as Windows 7 Starter doesn’t include the Sensors and Locations platform.

Getting Started

Geosense is a free download for Windows 7, with both 32 and 64 bit editions.  Choose the correct one for your computer, and install.

While installing, it will ask to install a device driver.  Simply press Install.  You may also see a UAC prompt, which you should accept as well.

When it is finished installing, you are ready to use Geosense.  First, lets make sure Geosense is enabled.  Enter “Location” in your Start Menu search, and select “Location and Other Sensors”.

Here you should see Geosense listed as a sensor.  If it is not enabled, click the check box beside it and click Apply.

You can see more information about Geosense if you click its name.  This page lets you change the description, choose which users can use this sensor, and uninstall it if you choose.

Using Geosense

There are few applications today that make use of the Location platform in Windows 7, but hopefully we will see more in the near future.  The weather desktop gadget, however, is location aware, so you can easily test out your Geosense location with it.  Once Geosense is installed, you will notice a grey logo beside your city’s name on the gadget that shows that a sensor is available.

Click on the gear to open the options pane.  Here you can now select “Find location automatically” and it will display the weather for the location detected by Geosense.

Now your gadget should show a blue icon beside the city name, showing that the location is coming from your location sensor.

Unfortunately, sometimes Geosense cannot detect your location. If so, you will either see an entirely incorrect city (Seattle, WA is the default city, and usually is “detected” if Geosense fails to detect your location), or will show a red icon showing that it cannot detect your correct location.

Location-Aware Google Maps

Another location aware application is a Google Maps app available from the Geosense site (link below).  This will automatically open a Google map at your current location, so you can easily search for directions and nearby businesses.  This could be very useful at a hotspot in a new city, for instance.  Once again, though, if it cannot detect your location, it may simply show a default location or a generic Google maps.

Windows only: Free utility Disk Space Fan analyzes your hard drive usage to help you determine what’s taking up space on your hard drive, representing it all with fancy visualization eye candy.

Disk Space Fan joins a long line of disk visualization tools, from the classic WinDirStat to DriveSpacio, Disktective, and others. WinDirStat has always had a special place in our hearts when it came time to visualize our hard drive usage and knock off space-wasting files, but it’s not the most attractive tool in the toolbox. Disk Space Fan does the same sort of disk analysis, but it’s also very attractive in addition to being very functional.

Eye candy aside, its scans are fast, and the Explorer integration makes it open up any file or folder for a closer look. You can click any slice to drill down further (and yes, it has fancy animated transitions when you do the clicking), and you can open or delete any file or folder directly from the app.

Disk Space Fan is a free download, Windows only. (Mac users, check out previously mentioned GrandPerspective.) A Pro version is available with a few more features, but the core features that make it great are available for free.
