Precision choice is of 5 decimal place is accurate to 1.11 meter (+/- 55.5 cm) at the equator. The accuracy of the latitude remains almost unchanged. The accuracy of the longitude increases the further from the equator you get. The Earth is not a sphere, but an irregular shape approximating an ellipsoid. ![]() Latitude and Longitude have the maximum error in the equator, because the earth' radius is maximum. Search on map Click on search to open the webpage Earth Coordinate, here you obtain the latitude and longitude simply by clicking on the map, and save the value by the button save. Coordinates Coordinates format is the pair of latitude and longitude, with sign minus (-) for the direction south latitude and west longitude separate by comma symbol (,), here some example: Seconds is a double value without sign, from 0 (or 0.0000) to 59.9999. Minute is an integer value without sign, from 0 to 59. Degree Degree format is composed of direction (N-S or W-E) and three sets of numbers separate by the symbols for degrees (°), minutes (’), and seconds (").ĭegree is an integer value without sign, from 0 to 90 for the latitude or from 0 to 180 for the longitude. ![]() Decimal You have to select a direction (N-S or W-E) and insert a number from 0 to 90 for the latitude or from 0 to 180 for the longitude (example 45.12345). # Sum the degrees to the decimal using the symbols for degrees (°) (-73.9874°)įormat Value range Valid value for the latitude are from -90.0° to 90.0° for the longitude are from -180.0° to 180.0°, the + sign should be omitted, while the minus sign is not necessary if there is a radio component to select the direction N-S or W-E (Degree and Decimal format). # The resulting is the decimal value of degrees (0.9874) # Sum the resulting to the minute and divide by 60 (59.244/60 = 0.9874) # The whole units of degrees will remain the same How to convert from a sexagesimal to decimal # Take your three sets of numbers and put them together, using the symbols for degrees (°), minutes (’), and seconds (") (-73° 59’ 14.64" longitude) # The resulting number becomes the seconds (14.64"). # Take the remaining decimal and multiply by 60. # The whole number becomes the minutes (59’) # The whole units of degrees will remain the same (-73.9874° longitude, start with 73°) How to convert from a decimal to sexagesimal If you wish to change the behavior if the functions, you can edit the code by going to Tools > Script Editor > utmconv.gs in the spreadsheet you copied from above.Content How to convert from a decimal to sexagesimal How to convert from a sexagesimal to decimal Format Accuracy Comment References Back to top Content Just open this spreadsheet , make a copy and see the formulae in action. With this script enabled in your Google Spreadsheet, you have access to 2 custom functions – DegreesToUTM(latitude, longitude) and UTMToDegrees(easting, norting, zone) that you can use in the formula like any other built-in function. I was able to adapt it to be used as a Apps Script in Google Spreadsheets. I found the excellent open-source YouTim: Javascript UTM Conversion library. As the data was being constantly updated, any offline solution that require exporting and importing the conversion would be cumbersome. They were collecting field data in UTM coordinates and needed a way to convert them to Latitude and Longitude to map them. Recently, someone presented me with an interesting challenge. ![]() cs2cs program, part of the PROJ.4 library is my favorite. There are a number of command line tools also available for performing bulk-conversions. Converting between different coordinate reference systems or projection is a fairly standard feature in a GIS.
