Location: A New Type of Data

The Mashup App allows you to save location data into your personal database. Location data can include the latitude and longitude of a place, Google Maps URL, the street/postal address, and neighborhood of a place, document, or media content such as images, audio, and video. 

Due to the desktop metaphor of files and folders, computer users have had limited exposure to location data and usually only through specialized photo management applications and photo sharing web sites. Enterprise databases have recently added support for location data. Database researchers describe databases with location support as geo-spatial databases. 

Your device can determine the latitude and longitude of its location. Unfortunately, this may not be very accurate so The Mashup App allows you to edit the location data to ensure the best possible accuracy. Using the latitude and longitude information generated by your device, The Mashup App can then determine the street address of the location by querying Location Servers found on the internet. This feature is called geolocation. 

The Mashup App does not transmit any personal data nor does it transmit your unique device identifier and only transmits to the Location Servers the latitude and longitude.
 
In addition to the street address, The Mashup App also uses Location Servers on the internet to determine the neighborhood for an address. This is helpful so that you can search your personal database for locations in a neighborhood, a city, or a state. Likewise, The Mashup App allows you to search your personal database for nearby places. For example, you can find places within a few miles from your current location.

 
The Mashup App can display location data on a map and you can share your location via email or SMS text messages.

There are 4 major benefits for saving location data: 

  1. Saving your current location. The Mashup App can determine the street/postal address, neighborhood, and the latitude and longitude of your device. This is helpful if you want to remember an address  or information about an unfamiliar place. You can provide a detailed description about the location, describe nearby places, and share with friends.

    If your data has location information associated with it or if it is a real-world place, you can browse and search by neighborhood, city, or state.
    Of course, you can visualize your location data on a map.

  2. Saving your location during a trip. The Mashup App can create a location log which you can visualize on a map. This helps you remember the streets you travelled on a trip, perhaps while sightseeing. The Mashup App is intelligent and will do its best to limit the drain on your device's battery.

    From the location log you can visualize your trip on an interactive map.

    The Mashup App provides detailed information about each place you visited.

  3. You can add location data to web and PDF documents as well as images, audio, and video content. Users such as rescue workers, archaeologists, and historians can use The Mashup App to quickly associate location and time data with their artifacts while in the field. The Mashup App also supports comprehensive reporting allowing the user to generate GeoRSS feeds.


    In addition to generating an RSS feed, GeoRSS feed, and custom web site from your data, you can also generate a formal report with a table of contents.

  4. Alerting you of important nearby places. For the mobile professional or just a person getting their clothes from the cleaners, The Mashup App can automatically display the data related to a location just before you arrive. So if you save your presentations and receipts in your personal database, you can always be prepared. This feature is called Vicinity Alerts and is based on a technology called geofencing.

    The Mashup App also allows you to set a Vicinity Alert around a location. When you travel near that location, The Mashup App will notify you that you are in the general area of that location and display any data related to the location. Vicinity Alerts decrease the time it takes to search your personal database by preloading and displaying data before you need it. This is helpful for mobile users who travel for business meetings or when you go to a place such as the cleaners where you must display a receipt. If you save your presentation and receipt in your personal database, The Mashup App will automatically search and display your data just before you arrive at your destination.
