Good news ! While I have been figuring it out and looking at the help on this problem..Sigh It is been battle back and forth for me . The problem is in the Creating Mosaic Dataset.. This works ! I have made a lot of change from the original code I post yesterday... I had to copy the code from this reateMosaicDataset example 2 (stand-alone script)  ArcGIS Help 10.1 it was giving several problems.... the prjfile does not work... so I add the the SpatialReference with WKID in it and make sure the code in one line..example see 26 ################################################################################ #            CREATE FILE GEODATABASE AND THEN CREATE MOSAIC DATASET            # ################################################################################ # Name: CreateFileGDB_Example2.py # Description: Create a file GDB # Import system modules import arcpy,os,sys arcpy.env.workspace = "C:/workspace" # Set local variables out_folder_path = "C:/workspace" out_name = "Think.gdb" # Execute CreateFileGDB arcpy.CreateFileGDB_management(out_folder_path, out_name) # Creating new Mosaic Dataset within Existing File Geodatbase try:     gdbname = "Think.gdb"     mdname = "SeeIfThisWorks"     prjfile = arcpy.SpatialReference(26913)     noband = "3"     pixtype = "8_BIT_UNSIGNED"     pdef = "NONE"     wavelength = ""     arcpy.CreateMosaicDataset_management(gdbname, mdname, prjfile, noband,pixtype, pdef, wavelength) except:     print "Create Mosaic Dataset failed" ...

I would export your polygons to geodatabase first and have the polygon as a backup..  Once you export it to geodatabase then add the topology and that should help you find the overlaps.... To learn about it go here...ArcGIS Help 10.1 ... View more

Thank you all. First of all, The file for the FTP server I have checked is no longer there or may have been moved; however, I tweaked and change to a different file to test it. The script is working now . If you compare the scripts I post earlier and the change I made.... I would like to Thank to Owen Earley for pointing me to the missing "else".  That worked ! # Import modules import ftplib import os import socket from ftplib import FTP HOST = "ftp.nifc.gov" DIRN = "Incident_Specific_Data/ALASKA/DataRequests/" FILE = "AK_UIA_polygon_data.gdb.zip" # Create a block to connection or not try:     f = ftplib.FTP(HOST) except (socket.error, socket.gaierror), e:         print "ERROR: cannot reach" % HOST else:         print '"***Connected to host "%s"' % HOST # to log in anonymously try:     f.login() except ftplib.error_perm:     print "ERROR: cannot login anonymously"     f.quit() else:     print '***Logged in as anonymous' # To change to the directory in DIRN try:     f.cwd(DIRN) except ftplib.error_perm:     print 'ERROR: cannot CD to" "%s'  % DIRN     f.quit() else:     print '***Changed to "%s" folder' % DIRN # Use the FTP Directory to retrieve KMZ try:     f.retrbinary('RETR %s' % FILE, open(FILE, 'wb').write) except ftplib.error_perm:     print "ERROR: cannot read file" % FILE     os.unlink(FILE) else:     print "***Downloaded %s to CWD" % FILE # Disconnect from FTP f.quit() ...

While this is a good tempting to use it on your personal computer it is a good to have; however my computer is under the Government so we are not allowed to download these programs on them. We were able to recovery it by requesting our IT department to restore it. ... View more

I am not sure if you are aware that there is another good site for you to read... it is called GIS Stackexchange where everyone share their GIS problems. I looked it up for your similiar situation and found a lot of good information... The website is Geographic Information Systems Stack Exchange Type Mosaic Dataset  Good luck. ... View more

@Dan Patterson Sorry, this code came from the book I am working on from Eric Pimpler's ebook "Programming ArcGIS 10.1 with Python cookbook. That book was in 2013 Yes I find a lot of errors in that book however I tried to tweak some of the codes but was not able to figure it out and I thought there must be a way around to correct it.. ...

You should be able to use this method... might want to look at here Image Management Workflows | ArcGIS Resource Center Honestly, it is an awkward workflow but I had to work on it for many hours until I understand how it works... Like I said I did work on NAIP for New Mexico and i was able to get it right..it took me to figure it out about three days...  I have asked others here on the GeoNet and only few people repsond me back... Do you have background in Erdas or Envi  ? ... View more
