Geofence
A geofence is a virtual perimeter for a real-world geographic area. A geofence could be dynamically generated (as in a radius around a point location) or match a predefined set of boundaries (such as school zones or neighborhood boundaries). The use of a geofence is called geofencing, and one example of use involves a location-aware device of a location-based service (LBS) user entering or exiting a geofence. Geofencing approach is based on the observation that users move from one place to another and then stay at that place for a while. This method combines awareness of the user's current location with awareness of the user's proximity to locations that may be of interest. This activity could trigger an alert to the device's user as well as messaging to the geofence operator. This info, which could contain the location of the device, could be sent to a mobile telephone or an email account. History Geofencing was invented in the early 1990’s and patented in 1995 by American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geo-fence Warrant
A geo-fence warrant (also known as a geofence warrant or a reverse location warrant) is a search warrant issued by a court to allow law enforcement to search a database to find all active mobile devices within a particular geo-fence area. Courts have granted law enforcement geo-fence warrants to obtain information from databases such as Google's Sensorvault, which collects users' historical geolocation data. Geo-fence warrants are a part of a category of warrants known as reverse search warrants. History Geo-fence warrants were first used in 2016. Google reported that it had received 982 such warrants in 2018, 8,396 in 2019, and 11,554 in 2020. A 2021 transparency report showed that 25% of data requests from law enforcement to Google were geo-fence data requests. Google is the most common recipient of geo-fence warrants and the main provider of such data, although companies including Apple, Snapchat, Lyft, and Uber have also received such warrants.

Geomessaging
Geomessaging is a technology that allows a person or system to send a message based on any media to a device that enters or exits one or more regions. Those regions can be created by using geofences, based on Latitude and Longitude, or adding beacons to the system associating those beacons with named locations. The device will receive the message according to the rules defined by the campaign administrator (the person or system in charge of defining those locations and messages). Rules can be: The minimum time to wait before resending a message, weekday, time range, etc. The content of the message associated to those rules can be any images, text, html, metadata key-value pair, etc. Increasingly geomessaging is finding its use in various applications including crisis communication and geo-location sensitive communication management. Geomessage media Geomessage Media defines a media genre where information or messages can be sent to recipients based on their location. Platforms t ...

Global Positioning System
The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephonic or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls and maintains the GPS system, it is freely accessible to anyone with a GPS receiver. The GPS project was started by the U.S. Department of Defense in 1973. The first prototype spacecraft was lau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locationized Firearms
A location-based firearm is a gun that uses electronic technologies such as geofencing to restrict its firing to authorized locations, thereby allowing its use for protecting life and property in those locations while preventing its use in other locations for crimes such as robberies, drive-by shootings, assassinations, and massacres. History The first locationized gun was invented by John Martin in 1984. Although locationized guns could prevent much crime and accompanying deaths and injuries, they have not been commercially developed. An important reason for that is because legislated restrictions would be required for conventional guns, and those restrictions would be difficult to pass in some markets. Operating principles, advantages, and technologies The main advantage of locationized guns is that they can satisfy the right to possess arms for defense of homes and businesses while being useless for many crimes that can be committed away from those homes and businesses. ...

''Ingress'' uses the mobile device GPS to locate and interact with "portals" which are in proximity to the player's real-world location. The portals are physical points of interest where "human creativity and ingenuity is expressed" often manifesting as public art such as statues and monuments, unique architecture, outdoor murals, historic buildings, local community hubs and other displays of human achievement. The game uses the portals as elements of a science fiction backstory along with a continuous open narrative provided t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GPS Tracking
A GPS tracking unit, geotracking unit, satellite tracking unit, or simply tracker is a navigation device normally on a vehicle, asset, person or animal that uses satellite navigation to determine its movement and determine its WGS84 UTM geographic position ( geotracking) to determine its location. Satellite tracking devices send special satellite signals that are processed by a receiver. Locations are stored in the tracking unit or transmitted to an Internet-connected device using the cellular network ( GSM/GPRS/ CDMA/ LTE or SMS), radio, or satellite modem embedded in the unit or WiFi work worldwide. GPS antenna size limits tracker size, often smaller than a half-dollar (diameter 30.61 mm). In 2020 tracking is a $2 billion business plus military-in the gulf war 10% or more targets used trackers. Virtually every cellphone tracks its movements. Tracks can be map displayed in real time, using GPS tracking software and devices with GPS capability. Architecture A GPS "trac ...

GPS Drawing
GPS Drawing, also known as GPS Art, is a method of drawing where an artist uses a Global Positioning System (GPS) device and follows a pre-planned route to create a large-scale picture or pattern. The .GPX data file recorded during the drawing process is then visualised, usually overlaying it as a line on a map of the area. Artists usually run or cycle the route—while cars, vans, boats and aeroplanes are utilized to create larger pieces. The first known GPS drawing was made by Reid Stowe in 1999. "Voyage of the Turtle" is an ocean sized drawing with a 5,500 mile circumference in the Atlantic made using a sailboat. The GPS data was recorded in logbooks and was therefore very low resolution. In 2000, after the US Military GPS satellite signals were opened up to the public, artists Jeremy Wood and Hugh Pryor were able to use a newly available GPS tracker to record their movements. To display their drawings Hugh Pryor wrote a computer program which convented the GPX data into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geotagging
Geotagging, or GeoTagging, is the process of adding geographical identification metadata to various media such as a geotagged photograph or video, websites, SMS messages, QR Codes or RSS feeds and is a form of geospatial metadata. This data usually consists of latitude and longitude coordinates, though they can also include altitude, bearing, distance, accuracy data, and place names, and perhaps a time stamp. Geotagging can help users find a wide variety of location-specific information from a device. For instance, someone can find images taken near a given location by entering latitude and longitude coordinates into a suitable image search engine. Geotagging-enabled information services can also potentially be used to find location-based news, websites, or other resources. Geotagging can tell users the location of the content of a given picture or other media or the point of view, and conversely on some media platforms show media relevant to a given location.

Cell Broadcast
Cell Broadcast (CB) is a method of sending messages to multiple mobile telephone users in a defined area at the same time. It is defined by the ETSI’s GSM committee and 3GPP and is part of the 2G, 3G, 4G LTE (telecommunication) and 5G standards. It is also known as Short Message Service-Cell Broadcast (SMS-CB) or CB SMS. Unlike Short Message Service-Point to Point (SMS-PP), Cell Broadcast is a one-to-many geo-targeted and geo-fenced messaging service. History Cell Broadcast messaging was first demonstrated in Paris in 1997. Some mobile operators used Cell Broadcast for communicating the area code of the antenna cell to the mobile user (via channel 050), for nationwide or citywide alerting, weather reports, mass messaging, location-based news, etc. Cell broadcast has been widely deployed since 2008 by major Asian, US, Canadian, South American and European network operators. Not all operators have the Cell Broadcast messaging function activated in their network yet, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
