The Standard Point Location Code® (SPLC™) is a 9 digit geographic code used by North American transportation industries, especially rail. SPLC is owned and maintained by the National Motor Freight Traffic Association. [1] SPLC exist for terminals within the United States, Canada, and Mexico. For the US and Canada, the first two digits refer ...
ISO 6709, Standard representation of geographic point location by coordinates, is the international standard for representation of latitude, longitude and altitude for geographic point locations. The first edition (ISO 6709:1983) was developed by ISO/IEC JTC 1/SC 32.
SPLC may also refer to: Software Product Line Conference, an annual international conference; Student Press Law Center, an American nonprofit journalism organization headquartered in Washington, D.C. Standard Point Location Code, a 9-digit geographic code used by North American transportation industries; St. Peter's Lutheran Church, Hobart ...
The number of digits in the numerical location must be even: 0, 2, 4, 6, 8 or 10, depending on the desired precision. When changing precision levels, it is important to truncate rather than round the easting and northing values to ensure the more precise polygon will remain within the boundaries of the less precise polygon.
Plus Codes logo. The Open Location Code (OLC) is a geocode based on a system of regular grids for identifying an area anywhere on the Earth. [1] It was developed at Google's Zürich engineering office, [2] and released late October 2014. [3] Location codes created by the OLC system are referred to as "plus codes".
Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).
Simple Features (officially Simple Feature Access) is a set of standards that specify a common storage and access model of geographic features made of mostly two-dimensional geometries (point, line, polygon, multi-point, multi-line, etc.) used by geographic databases and geographic information systems.
Therefore, we reduce our point location problem to two simpler problems: [2] Given a subdivision of the plane into vertical slabs, determine which slab contains a given point. Given a slab subdivided into regions by non-intersecting segments that completely cross the slab from left to right, determine which region contains a given point.
