Using the 6-digit postal code to look up the Central Public Lirbary in the OneMap application. Due to Singapore being a small city-state and most buildings having singular, dedicated delivery points, the postal code can be used as a succinct and precise identifier of buildings in Singapore, akin to a geocode.
Once a match is made, the location of the reference feature can be attached to the input row. These algorithms are of two types: Direct match The geocoder expects each input item to directly correspond to a single entire feature in the reference dataset. For example, a country or zip code, or matching street addresses to building point ...
There are also mixed systems, using a syntactical partition, where for example the first part (code prefix) is a name-code and the other part (code suffix) is a grid-code. Example: Mapcode entrance to the elevator of the Eiffel Tower in Paris is FR-4J.Q2, where FR is the name-code [9] and 4J.Q2 is the grid-code. Semantically France is the ...
The Unique Property Reference Number (UPRN) is a unique number (a geocode) for every addressable location—e.g., a building, a bus stop, a post box, a feature in the landscape, or a defibrillator—in Great Britain. [1] Over 42 million locations have UPRNs, which can be found in Ordnance Survey's AddressBase databases. [1]
The High Accuracy Reference Network (HARN), a high accuracy version of the NADCON transforms, have an accuracy of approximately 5 centimeters. The National Transformation version 2 is a Canadian version of NADCON for transforming between NAD 1927 and NAD 1983. HARNs are also known as NAD 83/91 and High Precision Grid Networks (HPGN). [27]
An MGRS grid reference is a point reference system. When the term 'grid square' is used, it can refer to a square with a side length of 10 km (6 mi), 1 km, 100 m (328 ft), 10 m or 1 m, depending on the precision of the coordinates provided.
Since, in the UK at least, a 6-figure grid reference identifies a square of 100-metre sides, an 8-figure reference would identify a 10-metre square, and a 10-digit reference a 1-metre square. In order to give a standard 6-figure grid reference from a 10-figure GPS readout, the 4th, 5th, 9th and 10th digits must be omitted, so it is important ...
Natural Area Code, also called Universal Address, is a geocode generated by the Natural Area Coding System - a public domain geocode system for identifying an area (also a location when the area is relatively small enough) anywhere on the Earth, or a volume of space anywhere around and inside the Earth.
