What Is Address Geocoding?
Geocoding is a coding set to identify the positions and attributes of points, lines, and areas. It selects the most appropriate quantization method for all entities according to a predetermined classification system, and records them in the data structure of entity attributes and collection coordinates. Computer storage device.
Geocoding
Right!
- Geocoding is a coding set to identify the positions and attributes of points, lines, and areas. It selects the most appropriate quantization method for all entities according to a predetermined classification system, and records them in the data structure of entity attributes and collection coordinates. Computer storage device.
- The forward geocoding service implements the function of converting an address or place name description into a corresponding location on the surface of the earth.
The professional and diversified engines and rich database data provided by forward geocoding make the service application very extensive, creating unlimited business value for users in terms of asset management, planning analysis, supply and logistics management, and mobile input.
- Reverse geocoding service
- The reverse geocoding service realizes the process of converting the address coordinates of the earth's surface into a standard address. The reverse geocoding provides a coordinate positioning engine to help users reverse query to find the location of a feature based on the coordinate value of a feature on the ground. Administrative divisions, streets, and best-matching standard address information. The data in the rich standard address library can help users create unlimited value in the fields of mobile terminal query, business analysis, and planning analysis.
- Vector geocoding
- Vector geocoding refers to the use of coordinate reference systems to define the locations of point, line, and area features. Vectorization (vectorization): Refers to the process of converting network format data into vector form.
- Grid geocoding
- Raster geocoding refers to the use of
- Also known as address matching.
- Geocoding in MapInfo
- Its concept is different from the general coding definition. It does not use numbers or letters to represent an object, but assigns point-like targets to a row of attribute data records. The field data in the records is used to correspond to the corresponding data in the graphic database. The fields match to determine where the record point should be on the map.
- In other words, according to the geographic coordinates or spatial addresses of each data point (such as provinces, cities, neighborhoods, floors, rooms, etc.), the data in the database is corresponding to the corresponding graphic elements on the map one by one. That is, the process of assigning X and Y values to each data to determine the position of the data on the graph. The table into which point objects are inserted is called the target table, and the geographic coordinates of the points are derived from a source table with a map.
- SuperMap address matching module
- The basic development platform SuperMap Objects in the latest SuperMap GIS series software, SuperMap Objects, contains AddressMatching Module, which can provide Chinese address fuzzy matching search function. This function is based on an address dictionary, which can perform address matching on multiple layers in the map.
- The geocoding services provided by Beijing Jietai Technology Co., Ltd. include forward geocoding and reverse geocoding services. Among them, forward geocoding provides three service engines: address positioning engine, administrative division engine, and street engine. Geocoding provides a coordinate engine. The service now covers 369 cities and is updated twice a year.
