Convert latitude and longitude to utm12/27/2023 ![]() Similarly, any point on the earth can be defined with a pair of numbers which are called geographic coordinates (latitude, Longitude) assuming that Earth is Sphere. West: The direction opposite to the Earth's rotation is West.Ĭartesian coordinate is a point defined by x and y (a pair of numbers) in a plane. Describing positions on the surface of the Earth in Latitude and Longitude are the most common representation of spatial data and is called Geographic Coordinate Systems.Įast: The direction parallel to the Equator and toward which the Earth's rotation is Geographical coordinate System (Global Coordinate Systems) (i.e., Latitude and Longitude values, in degrees,įor sufficient accuracy to allow global exploration, navigation, and mapping earth is considered as spherical for Mathematical Modeling. But when maps represent the bigger area, Curvature of Earth has to be considered and hence there is a need for the geographical coordinate system. ![]() When the survey is done for less than 10 Km, variation due to the curvature of the earth will be insignificant and flat earth models can be used. So the Cartesian coordinate system cannot be used to represent Earth Surface as Earth has a Spherical Surface. Each reference line is called a coordinate axis or just axis of the system, and the point where they meet is its origin, usually, at ordered pair (0,0),Įarth is not a Flat Surface. Universal Transverse Mercator coordinate systemĪ Cartesian coordinate system specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances from the point to two fixed perpendicular directed lines, measured in the same unit of length.This white paper explains which are the factors to be understood for Latitude and Longitude Conversion. Out Excel will have converted Data as shown below formatĬonverting Latitude Longitude into Map Coordinate is not a single step conversion as in most of the conversion from one unit to another unit by applying a simple formula. Then converted Data will be downloaded in Download folder as LatLong.xlsx fileħ. ![]() Click on Browse button to select LatLong CSV fileĦ.

I did not include a WRITEEXCEL formula to post the results back to the spreadsheet, because I just discovered this omission and want to get this uploaded before I go home for the evening. zip file is used in the worksheet to read in data. For users of other versions of Mathcad, the. This worksheet is in Mathcad Prime 3.0 format. This worksheet provides two data entry methods: internal tables and external Excel spreadsheets. The ellipsoid data in this worksheet is for World Geodetic System 1984 (WGS 84), which is very close to North American Datum 1983 (NAD 83). Results are accurate to about one millimeter within 3,000 km of a UTM Zone's central meridian. These two programs and the preliminary calculations for them use a truncated version of the Transverse Mercator flattening series derived by Johann Heinrich Louis Krüger in 1912. This worksheet provides separate program functions to convert Lat/Lon coordinates to UTM and UTM coordinates to Lat/Lon. The purpose of this worksheet is to convert geographic coordinates between latitude/longitude (Lat/Lon) and Universal Transverse Mercator (UTM).
