# 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. Military Grid Reference System (MGRS and MGRS 16)įor the Input Coordinate Format parameter options DD 1, DDM 1, and DMS 1, the latitude and longitude values must represent a location that is concatenated together and stored in a single field.įor the DD 2, DDM 2, and DMS 2 options, the latitude and longitude values are represented by two separate fields.įor the DD numeric option, the latitude and longitude values are stored in two separate fields of type double.įor the Gars, Georef, Georef 16, UTM zones, UTM bands, USNG, USNG 16, MGRS and MGRS 16 options, the values are single-string coordinate formats, meaning only one field contains the coordinate.įor the Input Coordinate Format and Output Coordinate Format parameters, the MGRS 16 (example: 11SLT7858811533670379), USNG 16, and Georef 16 options have higher precision (16 digits) than the equivalent MGRS (example: 11SLT78588115), USNG, and Georef options (8 digits).Īll fields from the input table, including the OID field and the input format fields, will be transferred to the output point feature class.United States National Grid (USNG and USNG 16).World Geographic Reference System (GEOREF and GEOREF 16).The default is GCS_WGS_1984 unless the input table is a feature class, in which case the default is the coordinate system of the input features. (Latitude) values is specified with the Input Coordinate System parameter. Click OK in the Data Export Options dialog, and the new file with lat/long coordinates is created.The coordinate system of the values stored in the X Field.In the Export dialog, set the Save as type to DAT Golden Software Data (*.dat).Click OK and the data will appear in lat/long.Click Map | Change Projection and expand the coordinate system tree to Predefined | Geographic (lat/lon).Your data will display in the plot window. WGS84 or North America), and then choose the coordinate system for the appropriate zone. Expand the datum or region your coordinates were collected in (i.e.In the Assign Coordinate System dialog, set the Coordinate Space Type to Projected and expand the coordinate system tree to UTM ( Predefined | Projected Systems | UTM).
