It sounds that you have LiDAR data, but in a less adequate format xyz. To use large amounts of LiDAR data as point features is not the most efficient way to handle this type of data. In case you also received .las data, use that instead and create a LAS dataset from it. Info here: ArcGIS Help (10.2, 10.2.1, and 10.2.2) In case you don't have LAS file(s), you can convert your .xyz file to a .las file by using LAS Tools using txt2las.exe. Have a look at slide 6 from my presentation: Playing around with LiDAR, AHN2, Aerial Photography and LAStools in A… It is really easy... Once you have the LAS dataset in ArcGIS, you can convert it to raster without any problem: ArcGIS Help (10.2, 10.2.1, and 10.2.2) ... View more

When a parameter is not set, this is normally replaced by a "#" sign. I did a small test and reading the optional parameter when it is supposed to be an object ended in a "Object: Error in getting parameter as text" error. So I placed it in a try except and assigned it to None when there is an error (presumably the parameter was not set). I guess you could do something like this: # Import all necessary modules import os, sys, arcpy from arcpy import env import getpass # Define all objects to be used sde_conn = "S:/Projects/Oilsands/FortHills/OS0101_Fort_Hills_MPG/010_FH_GDA/002-GDA_LOG/My_ArcSDE_Conn.sde" gdaFC = "FORTHILLS.GDA_PERMIT_BOUNDARY_A" fld_gdanum = "GDA_NUMBER" # Prompt for user parameters table = arcpy.GetParameterAsText(0) field = arcpy.GetParameterAsText(1) gdanum = arcpy.GetParameterAsText(2) extstart = arcpy.GetParameter(3) extend = arcpy.GetParameter(4) extdue = arcpy.GetParameter(5) try:     asbsubmit = arcpy.GetParameter(6) # Optional Parameter except:     asbsubmit = None ##arcpy.SetParameter(3, gdanum) # Specify selection fc = os.path.join(sde_conn, gdaFC) whereClause = "{0} = '{1}'".format(arcpy.AddFieldDelimiters(fc, fld_gdanum), gdanum) # Updates information of gda feature class try:     cursor = arcpy.UpdateCursor(fc, whereClause)     for row in cursor:         row.setValue("EXTENSION_START_DATE", extstart)         row.setValue("EXTENSION_FINISH_DATE", extend)         row.setValue("EXTENSION_DUE_DATE", extdue)         if asbsubmit != None:             row.setValue("ASBUILT_SUBMIT_DATE", asbsubmit) # Script should skip this if no value entered         row.setValue("STATUS", "E")         row.setValue("INTERNAL_ROW_CHANGED_DATE", time.strftime("%x %X", time.localtime()))         row.setValue("INTERNAL_ROW_CHANGED_BY", getpass.getuser().upper())         cursor.updateRow(row)     del cursor, row except:     print arcpy.GetMessages(1) arcpy.AddMessage("GDA has been extended") I switched line 22 off. Not sure why you want to set the value of the parameter extstart (3) to contain the value contained in gdanum... ... View more

If you want to update all feature classes in a workspace, you could use some Python code to do so: import arcpy import os ws = r"C:\Forum\DistLinePol\test.gdb" fld_x = "POINT_X" fld_y = "POINT_Y" arcpy.env.workspace = ws fds = arcpy.ListDatasets() fds.append("") for fd in fds:     fcs = arcpy.ListFeatureClasses(feature_dataset=fd)     for fc in fcs:         fcl = os.path.join(ws, fd, fc)         shape_type = arcpy.Describe(fcl).shapeType         if len(arcpy.ListFields(fcl, fld_x)) == 0:             arcpy.AddField_management(fcl, fld_x, "DOUBLE")         if len(arcpy.ListFields(fcl, fld_y)) == 0:             arcpy.AddField_management(fcl, fld_y, "DOUBLE")         with arcpy.da.UpdateCursor(fcl, ("SHAPE@", fld_x, fld_y)) as curs:             for row in curs:                 if shape_type == "Point":                     row[1] = row[0].firstPoint.X                     row[2] = row[0].firstPoint.Y                 elif shape_type == "Polyline":                     pnt = row[0].positionAlongLine(0.5, True)                     row[1] = pnt.firstPoint.X                     row[2] = pnt.firstPoint.Y                 elif shape_type == "Polygon":                     row[1] = row[0].centroid.X                     row[2] = row[0].centroid.Y                 curs.updateRow(row) Change the values on line 4 to 6 to set the path to the workspace and the fields to update. If the fields don't exist they are added in the process. ... View more
