What is geocoding?

Geocoding is a method of distinguishing one type of geographical information from other geographical information. Using known locations, such as street addresses or properties information, it is possible to extrapolate coordinates. These coordinates can then be added to the global positioning or navigation system. Geocoding is essential for certain types of modern response systems to emergency situations and decentralized navigation platforms. However, geocoding has created a controversy surrounding certain methods of its use.

Geocoding generally works by two methods, interpolation and triangulation. The interpolated location is common in negotiations with cities and addresses. If the address is required and the system already knows the address on both sides on the same street, this information can be used to find the desired location. Because the addresses are set by the distance from each other and alternate on the street, the program simply calculates how many numbers are the desired address from the Thummy address. That's why many global positionsSpecifically, the intersections focus on the systems (GPS). Interpolation

is common in reaction systems to emergency situations. These systems know the address of the caller from the computer system. The address is then entered in the geocoding system, where other known addresses are used to find its coordinates. This information is then entered in the navigation system, which is broadcast by an emergency team where it must go. Mobile phones use reverse geocoding - provides coordinates and software finds its location.

The second common method is triangulation. This method is usually used in places where there are no linear connection points. In this case, the exact location is determined through other close places. The software takes nearby known coordinates and triangulates the location of a new location. The more nearby places that the system knows, the more accurate the results.

geocoding based on triangulation is a common featureIn most hand GPS receivers. These systems use the chip inside the unit to find basic coordinates. These coordinates are then verified by the triangulation of other known coordinates in the area. This form of geocode also works well in planning wilderness trips, as coordinates can be identified before entering an area that allows easier navigation to the desired destination.

Geocoding, especially interpolation, allows users to obtain a surprising amount of personal data. Using these systems combined with other open databases, the person can be monitored quite easily. This is especially for individuals who have committed crimes that require local registration. As a result, several groups of guard dogs feel that geocoding and many other geographical systems attack people's privacy and need stricter regulations.
