Look into the ArcScan toolset. Part of its functionality includes converting raster to vector. You will still need to hand attribute, but perhaps you can avoid hand digitizing. Best Regards, Jim

Try using append in a loop over your files, so that it is only working with 2 files at a time, instead of 15000 all at once. Best Regards, Jim

Assuming by "conversion factor" you want to move, scale, and rotate the data to match another dataset, you can create a world file that has the same name as the CAD file, in the same directory, with 2 known coordinate pairs representing the CAD x,y and the dataset's corresponding x,y. format is CADx,CADy Targetx,Targety CADx,CADy Targetx,Targety Link to the help on this: World files for CAD datasets—Help | ArcGIS for Desktop Best Regards, Jim

I have restarted my machine and it runs successfully now. I have no idea why it was failing previously, as I can look at the Geoprocessing Results tab, and see the same arguments entered with an unsuccessful result as what I have used for a successful result today. The entry for the string does not need any quotes, as Joshua surmised. ESRI support ran my code as provided with no troubles, I tried it on a different machine with no troubles, and then tried it again on mine with success. No idea what was preventing it before. Thanks to all for your help and input. Best Regards, Jim

That is a good thought, Joshua. I had tried that as well as using single quotes, double quotes, escaped quotes (/', \', " ' ", ' " ') No joy yet. I have submitted a support ticket to ESRI, and will let you all know what shakes out. Regards, Jim

That was my original thought as well. I have just tried: SearchStr = arcpy.GetParameterAsText(1) SearchStr = '"{}"'.format(SearchStr) No luck Tried: SearchStr = '"'+str(SearchStr)+'"' No luck The parameter is set to a string type in the dialog. Actually at a bit of a loss for what else to try.

I don't quite follow. The code runs without issues if I hardcode the SearchStr variable. Lines 20 and 24 turn on the layer prior to export, and then turn it back off before the next event theme is turned on and exported. Line 30 is simply an add message statement so I can see what the code is working with, and line 34 is just an active view refresh. Perhaps the line numbers are skewed? Thanks for your input just the same!

I have a very simple program to toggle on and off layers and export PNGs. The issue is trying to pass a string to search for in the ListLayers result. If I pass the parameter with the tool dialog, I get no return, even though I AddMessage the string and it shows as expected (see the 4th line under Messages). If I hardcode the string on line 27: for lyr in arcpy.mapping.ListLayers(mxd, "*Events", df): , no troubles. I expect I am missing something basic in the interpolation of the passed string, but I have tried enclosing in additional quotes and using escapes before the quotes, to no avail. Best Regards, Jim import arcpy Folder = arcpy.GetParameterAsText(0) Folder = Folder.replace("\\","/") SearchStr = arcpy.GetParameterAsText(1) arcpy.AddMessage( SearchStr) mxd = arcpy.mapping.MapDocument("CURRENT") df = arcpy.mapping.ListDataFrames(mxd,"Layers") [0] def ExportPNG(sspaText): # Update the layout text #for el in arcpy.mapping.ListLayoutElements(mxd,"TEXT_ELEMENT","SSPA_Title"): # el.text = sspaText arcpy.AddMessage("Processing " + sspaText) arcpy.RefreshActiveView() # Export the Map arcpy.mapping.ExportToPNG(mxd, Folder + "/" + sspaText + ".png", resolution=600) def SetVisibility(visNam): for lyr in arcpy.mapping.ListLayers(mxd,visNam,df): lyr.visible = 'true' def SetInvisibility(visNam): for lyr in arcpy.mapping.ListLayers(mxd, visNam,df): lyr.visible = 'false' for lyr in arcpy.mapping.ListLayers(mxd, SearchStr, df): baseName = lyr.name arcpy.AddMessage(baseName) # Call the SetVisibility function to turn on the layer SetVisibility(baseName) arcpy.RefreshActiveView() sspaText = lyr.name[:-7] ExportPNG(sspaText) # Call the SetInvisibility function to turn off the layer SetInvisibility(baseName) ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Are your images the exact same extent? If not, you can not apply your control points from one to the others. If they are the same extents, and do not contain any georeferencing information already, you should be able to apply the same control point file to your images successfully. Best Regards, Jim

‎04-25-2016

I did not realize you were going to be moving it. Go under the data frame properties for the graticule data frame, and set the extent to "Other Data Frame". They will stay in sync then. Best Regards, Jim

‎04-25-2016

You could create a second data frame, with the same extents, and put it under the one with your features. Add your grid to this one, and it will appear underneath your features. Best Regards, Jim

Follow up: The python window shows: Succeeded at Fri Mar 04 10:..... (Elapsed Time 0.06 seconds) but this takes many minutes to pop up. Evidently the process itself is quite fast, but the sequential process is glacially slow.

I have over 200 ascii files, and a .lyr file for the classification I wish to set. I have used the following in the python window, but it is taking HOURS to cycle through. There must be a better way to do this, can anyone point me to a quicker / better solution? >>> import arcpy >>> mxd = arcpy.mapping.MapDocument("CURRENT") >>> df = arcpy.mapping.ListDataFrames(mxd, "*") [0] >>> lyrSource = r"Z:\1393_HANFORD_FY2016\062_FY2016_100_Areas_PT_Rpt\GIS\CrVI_ASC.lyr" >>> for lyr in arcpy.mapping.ListLayers(mxd, "*.asc",df): ... arcpy.ApplySymbologyFromLayer_management(lyr,lyrSource) Best Regards, Jim Cousins

I have encountered a similar issue, and the labels included leader lines, and annotation stored in the map. I found increased/acceptable performance by converting to annotation stored in a geodatabase. Regards, Jim

An additional source is the United States Department of Agriculture Farm Service Agency - Aerial Photography Field Office (APFO). They produce orders upon request, so you need to have some additional time built in, and they do charge a minimal fee, but still an often overlooked resource. Regards, Jim
