DNC To Geodatabase

Summary

Imports Digital Nautical Chart (DNC) formats into a DNC geodatabase. The product footprint will be created from the Dqyarea and written to the Product_Footprints feature class if it is within the schema.

Usage

  • Imports DNC VPF data.

  • Multiple scales can exist in the same geodatabase. For instance Harbor, Coastal, Approach, or General scales are stored in a DNC NIS for enterprise production.

  • This tool, in conjunction with Convert DNC GDB To VPF, can be used to migrate data from one geodatabase to a second geodatabase.

  • Notes are imported.

Syntax

arcpy.nautical.DncVpfToGeodatabase(Input_VPF_Features, Input_Target_Geodatabase)
ParameterExplanationData Type
Input_VPF_Features

The VPF data to be imported into the geodatabase from specific layers or a folder that contains one library. Point, line, and polygon features can be imported.

Use this tool in batch mode to import multiple library scales.

Workspace
Input_Target_Geodatabase

The geodatabase into which the VPF data will be imported. This can be a new or existing geodatabase.

Code sample

DncVpfToGeodatabase example

The following code sample demonstrates how to import DNC data into an enterprise geodatabase.

#import arcpy module
import arcpy, traceback, sys

# Check for Production Mapping extension 
print "Checking out Production Mapping extension" 
arcpy.AddMessage("Checking out Production Mapping extension") 
if arcpy.CheckExtension("foundation") == "Available": 
    arcpy.CheckOutExtension("foundation") 
else: 
    arcpy.AddError("Production Mapping license is unavailable.")

#Define variables
#Input VPF
dnc = r'C:\Data\DNC\Products\__Coastal\DNC17'
#Input Target Workspace
inputGDB = r'C:\Data\DNC\DNC_NIS.gdb'

try:
    #Execute tool
    print "Importing DNC data..."
    arcpy.DncVpfToGeodatabase_nautical(dnc, inputGDB)

except arcpy.ExecuteError:
    # Get the geoprocessing error messages
    msgs = arcpy.GetMessage(0)
    msgs += arcpy.GetMessages(2)

    # Write gp error messages to log
    print msgs + "\n"
    arcpy.AddError(msgs + "\n")


except:
    # Get the traceback object
    tb = sys.exc_info()[2]
    tbinfo = traceback.format_tb(tb)[0]

    # Concatenate information together concerning the error into a message string
    pymsg = tbinfo + "\n" + str(sys.exc_type)+ ": " + str(sys.exc_value)

    # Write Python error messages to log
    print pymsg + "\n"
    arcpy.AddError(pymsg + "\n")

print "DNC To Geodatabase completed"
