Hi,

I've a python code which was working in ArcGIS 10, but now since I've migrated to 10.2.2 didn't work.Basically it's a toolset which runs a python script. The tool allow the user to input coordinates in DMS or DDM, create the points and after track the path.Here is my error message:

      Traceback (most recent call last):
          File "C:\GP_TOOLS\VesselTrack.py", line 54, in <module>
            arcpy.ConvertCoordinateNotation_management(TableTemp, output_Vessel, "LATLONG","", coordinateformat, "DD")
          File "c:\program files (x86)\arcgis\desktop10.2\arcpy\arcpy\management.py", line 7652, in ConvertCoordinateNotation
            raise e
        ExecuteError: Failed to execute. Parameters are not valid.
        ERROR 000735: Y Field (Latitude): Value is required
        Failed to execute (ConvertCoordinateNotation).
    Failed to execute (VesselTrack).

The following is the code:

 #import arcgisscripting
    import arcpy, os
    from math import radians, sin, cos
    from arcpy import env
  
    # get the input & output parameters
    latitude = str(arcpy.GetParameterAsText(0))
    longitude = str(arcpy.GetParameterAsText(1))
    coordinateformat = arcpy.GetParameterAsText(2)
    description = str(arcpy.GetParameterAsText(3))
    link1 = str(arcpy.GetParameterAsText(4))
    link2 = str(arcpy.GetParameterAsText(5))
    delhistory = str(arcpy.GetParameterAsText(6))
    output_Vessel = arcpy.GetParameterAsText(7)
    output_Track = arcpy.GetParameterAsText(8)
  
    # Create table
    TablePath, outFC = os.path.split(output_Vessel)
    TableName = "TableTemp"
    TableTemp = os.path.join(TablePath, TableName)
    arcpy.CreateTable_management(TablePath, TableName)
  
    if str(coordinateformat) == "DDM" :
        arcpy.AddField_management(TableTemp, "LAT", "TEXT", "", "", 50)
        arcpy.AddField_management(TableTemp, "LON", "TEXT", "", "", 50)
  
        rows = arcpy.InsertCursor(TableTemp)
        row = rows.newRow()
        row.setValue("LAT", latitude)
        row.setValue("LON", longitude)
        rows.insertRow(row)
  
        del row
        del rows
  
        # Convert coordinates and create FC
        arcpy.ConvertCoordinateNotation_management(Table, output_Vessel, "LON", "LAT", coordinateformat, "DD")
  
    if str(coordinateformat) == "DMS" :
        arcpy.AddField_management(TableTemp, "LATLONG", "TEXT", "", "", 50)
  
        rows = arcpy.InsertCursor(TableTemp)
        row = rows.newRow()
        row.setValue("LATLONG", latitude + " " + longitude)
        rows.insertRow(row)
  
        del row
        del rows
  
        # Convert Coordinate Notation
        arcpy.ConvertCoordinateNotation_management(TableTemp, output_Vessel, "LATLONG","", coordinateformat, "DD")
  
    # Add the attributes to the Point FC
    arcpy.AddField_management(output_Vessel, "DESCR", "TEXT", "", "", 5000)
    arcpy.AddField_management(output_Vessel, "LINK1", "TEXT", "", "", 255)
    arcpy.AddField_management(output_Vessel, "LINK2", "TEXT", "", "", 255)
  
    arcpy.CalculateField_management(output_Vessel, "DESCR", '"' + description + '"', "PYTHON_9.3")
    arcpy.CalculateField_management(output_Vessel, "LINK1", '"' + link1 + '"', "PYTHON_9.3")
    arcpy.CalculateField_management(output_Vessel, "LINK2", '"' + link2 + '"', "PYTHON_9.3")
  
    # Keep the history (or remove if indicated)
    vessel_history = "//servername/data/Geoprocessing/TEST/GP_TOOLS_Vessel_Tracking/GP_Output.gdb/Output"
  
    if delhistory == 'true':
        arcpy.DeleteFeatures_management(vessel_history)
      
    arcpy.Append_management(output_Vessel, vessel_history, "NO_TEST")
    arcpy.Delete_management(output_Vessel)
    arcpy.Copy_management(vessel_history, output_Vessel)
  
    # Create line track
    Empty_Track = "//servername/data/Geoprocessing/TEST/GP_TOOLS_Vessel_Tracking/GP_Output.gdb/Empty_Track"
    if delhistory == 'true':
        arcpy.Copy_management(Empty_Track, output_Track)
      
    arcpy.PointsToLine_management(output_Vessel, output_Track)
  
    # Delete temp files
    arcpy.Delete_management(Table)

 

This line 54 is blocking the process:

arcpy.ConvertCoordinateNotation_management(TableTemp, output_Vessel, "LATLONG","", coordinateformat, "DD")

 

Can anyone highlight me if I missing something... Seems like he is no getting one of the parameters to create the feature class with the points. I want it to works on ArcGIS Desktop, so I can publish it and create a geoprocessing widget in flex viewer later. I can share my toolbox if needed.

 

Thanks in advance
