batch export jpeg with world files data driven pages

AntoninGosset — Thu, 16 Jun 2016 13:41:31 GMT

Hi there,

I'd like to know if it is possible to batch export jpg + world file (jpw or so) in batch using a Data Driven Pages python script.

I don't think it is possible because there is a limitation in Arcgis : the layout view doesn't permit the world file attachement and Data Driven Pages only exports layout views.

World file creation is only allowed in Data view.

I don't know if there is a trick / solution to do what I want to achieve using an advanced python script. A script that would run data driven pages in Layout View to export each view as JPG+ world file ?

Thanks

Example of python script to export Data driven pages as EMF in Data view

mxd = arcpy.mapping.MapDocument("CURRENT")

for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1):

mxd.dataDrivenPages.currentPageID = pageNum

arcpy.mapping.ExportToEMF(mxd, r"J:\81B\____Répertoires Trafic\60-Contributions_autres_agences\62-Production\Paris\16_RFF_SCH_SECTEUR\3_production\A_SIG_SchSect\PRODCARTO\11_Prospective\Carte_" + str(pageNum) + ".emf", convert_markers=True)

del mxd

ExportToJpeg does allow for world files So I am not sure what you are trying to export

Yes it does ... only for the data view as I said.

The data driven pages batch export only works with layout views, thus preventing to write world files ... so I'm stuck.

Thanks

I'm not adept at python, but I think what you'd need to do is somehow cycle through each index feature in data view, zoom to the index feature, export the data view, then repeat with the next index feature, and so on.

I think Dan is right, you can export the layout view to JPEG with a world file according to the documentation: ExportToJPEG—Help | ArcGIS for Desktop

ExportToJPEG (map_document, out_jpeg, {data_frame}, {df_export_width}, {df_export_height}, {resolution}, {world_file}, {color_mode}, {jpeg_quality}, {progressive})

And here is some code to iterate through your data driven pages:

mxd = arcpy.mapping.MapDocument("CURRENT")
# Iterate map series pages
for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1):
   mxd.dataDrivenPages.currentPageID = pageNum
   outFile = outputFolder + "\\" + mxd.dataDrivenPages.pageRow.getValue(mxd.dataDrivenPages.pageNameField.name) + ".jpg"
   arcpy.mapping.ExportToJPEG(mxd, outFile, resolution=150, world_file=True)

Thank you very much.

I'll test the code. I'm not the only one in my company who's interested to do it. It'll help us a lot.

Cheers

I ran a test but you know ... I'm don't know anything in python. I tried place my output files in C:\Export. Can you tell me what syntax should I use ?

>> mxd = arcpy.mapping.MapDocument("CURRENT")

... # Iterate map series pages

... for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1):

... mxd.dataDrivenPages.currentPageID = pageNum

... outFile = "C:\Export" + "\\" + mxd.dataDrivenPages.pageRow.getValue(mxd.dataDrivenPages.pageNameField.name) + ".jpg"

... arcpy.mapping.ExportToJPEG(mxd, outFile, resolution=150, world_file=True)

...

There's an error in your pathname. Luckily Dan Patterson wrote a real nice blog post on Python path names, which I would advise any novice Pythonian to take note of: Filenames and file paths in Python.

To mix strings and integers, use the str() function on the integers:

>>> "abc" + 123

When you are learning don't take short cuts

a = mxd.dataDrivenPages.pageNameField.name

print(a)

b = r "C:\Export" + "\\" + str(mxd.dataDrivenPages.pageRow.getValue(a)) + ".jpg"

print(b)

and see if it print out correctly

I tried but failed. Could you write the right code ? Thank you

what were the print statement results? and what were the errors?

DanPatterson_Retired — Fri, 17 Jun 2016 18:01:27 GMT

Did you scrunch all this together to save space?

mxd.dataDrivenPages.pageRow.getValue

and what did this print?

print(a)

I just tried to make it work but apparently it didn't. I don't know programming so I don't know what I'm doing.

Then start here: What is ArcPy?—Help | ArcGIS for Desktop

ArcPy/Python is an incredibly powerfull tool. If you need to do this in the future again, do yourself a favour and learn Python.

There's a space after the r before the pathname - not allowed.
