Here, we will use the Text to Columns option to separate the degrees, minutes, and seconds. Here, we have the latitudes and longitudes in DMS format, and so we will convert them into decimal values to create an Excel latitude-longitude converter. You can use any other version.Įxample-1: Converter of Latitude Longitude Degree, Minute, and Second to Decimal Values In the following two examples, we will show the process of converting DMS to Decimal and Decimal to DMS.įor creating this article, we have used Microsoft Excel 365 version. In the following dataset, we have some latitude and longitude values of some random places. The values are negative in the South and West positions and positive in the North and East positions.Ģ Examples to Create Latitude Longitude Converter in Excel It is generally represented in two formats Degree-Minute-Second (DMS), and Decimal. # DDLat field contains latitudes in a string fieldĪrcpy.CalculateField_management(in_table,"DDLatDbl","convertToDouble(!DDLat!)","PYTHON_9.Latitude-longitude is basically two numbers to represent the position of a place in the geographical coordinate system. # call CalculateField again to convert the values, 'S' is negative # add another field to store the numeric longitude valueĪrcpy.AddField_management(in_table, "DDLatDbl", "DOUBLE") # DDLon field contains longitudes in a string fieldĪrcpy.CalculateField_management(in_table,"DDLonDbl","convertToDouble(!DDLon!)","PYTHON_9.3",expr) # now call CalculateField tool to convert the values, 'W' is negative # add a field of type DOUBLE to store the numeric longitude valueĪrcpy.AddField_management(in_table, "DDLonDbl", "DOUBLE") # for DD_2 (and also for DD_1) format, the output values are in string format # output from Convert Coordinate Notation tool The tool can convert numeric notations DD, DMS, and DDM to other output formats, as long as the input values of DD, DMS, and DDM formats do not contain a letter character. These fields contain the coordinates of a point in the unit of the coordinate system of the feature class. The Add XY Coordinates tool can be used to add two fields- POINT_X and POINT_Y-to the output point feature class. If there are records with invalid notations, the tool messages will include the path of the log file that contains IDs of all invalid records. The Check Geometry tool can be used to identify records with invalid notations. Uncheck the Exclude records with invalid notation parameter to retain information regarding all input records. If a field with the same name as the input field already exists in the output, the name of the copied field will be appended with a unique number. For example, if the output format is MGRS, the new output field name will be MGRS. Output field names will be matched to the name of the output coordinate notation. The OID field values can be used to differentiate valid notations that are converted when the Exclude records with invalid notation parameter is checked.
