![]() That is very important and there are many utilities which can convert projection coordinates to lat/lon. The only reason I can think of where you would need to adopt a projection is if you were capturing coordinates from a paper map (and not a GPS/Phone), and/or legacy data stored as map projection coordinates. GPS provides location data in lat/lon, although units can be programmed to convert that to a particular map projection. The Coordinate Transformation Tool transforms GNSS based ETRS89 latitude and longitude or cartesian XYZ coordinates to the equivalent OSGB36 National Grid eastings and northings, and vice-versa, using Ordnance Surveys National Grid Transformation OSTN15. The natural coordinates for specifying locations on Earth are of course latitude and longitude linked to a ‘datum’ which specifies the size, and eccentricity of the slightly squashed sphere that is the earth. Digital applications (like Google Earth for example) don’t need to do that, they can visualise the curvature on the fly, in any way you want. It was very important when all we had were paper maps for locating and navigating. a way of projecting the curved surface of the earth onto a flat plane whilst preserving one, but not all, important parameters like distance, area or navigation angles. How to convert to UTM: Select the Input SRS (the default format is WGS84). ![]() And for the south hemisfere the latitud must be negative, as example Brasilia is on Lat: -15.78, Lon: -47.87 in decimal degrees.A co-ordinate system like UTM is a ‘map projection’, i.e. Please remind for the American Continent the longitud is negative. Note: a mismatch of 0.001 seconds is equivalent to 3 cm. Geographical coordinates: Longitude and Latitude can be entered in three different notations: decimal degrees: dd.ddddd degrees, decimal minutes: dd mm.mmm' degrees, minutes, seconds: dd mm' ss.s'' All formats or notations are converted into each other. User may click conversion button and compare the geographics coodinates reslt with the original input values. UTM zone (zone number), easting (x direction) and northing (y direction). Latitude and Longitude Converter Convert between Degrees, Minutes and Seconds and Decimal Units (or vice versa). Distance between 3D Points Distance between two points in a three dimension x, y and z coordinate system - online calculator. These values will be show in the exit box, but also they will be shown in the input box to convert from UTM to geographic coordinates. Convert builder's measurements to surveyor's measurements. It just so happens that the UTM projection system also uses WGS84 as the datum. Decimal degrees 156.742 converts to 156 degrees, 44 minutes and 31 seconds, or 156° 44 31'. 0.5260 31.2, so the whole number 31 equals seconds. If you want to have decimal minutes - here they are Ignore the third point. Projected is flat, geographic is 'round'. 0.74260 44.52, so the whole number 44 equals minutes. To convert latitude and longitude coordinates in decimal degrees to degrees with minutes and seconds, or degrees with decimal minutes follow these three steps: Take the integer - these are the degrees. WGS84 is properly a datum, but also refers to a geographic coordinate system whose units are degrees. When the data is enterd in a mode, the results are shown in the other mode. Follows the UTM coordinates and divides the world into 6-degree longitude and 20 latitude bands, but MGRS then further subdivides the grid zones into smaller. UTM is a projected coordinate system (aka CRS, what I think you mean in your comment) whose units are meters. Convert Geographic Coordinates to UTM & Viceversa EspañolĮxplanation & Verification You may input the data in Decimal Degrees or in Degrees Minutes & Seconds. On this page you can convert between geographic coordinates (in decimal degrees, degrees-minutes-seconds), Standard UTM, and NATO UTM.
