Accessing a Map Documents Bookmarks through Python and ArcPy

JayDouillard

Is there a way to access the bookmarks within a map document with arcpy? I have a mxd that has several bookmarks, and I'd like to write a script that zooms to the extent of each bookmark, and exports a pdf.

Good enhancement. This functionality is not available at 10. However, it is being investigated for a future release - perhaps 10.1. For your records, I will post the NIM tracking number when I have it.

Meanwhile, someone could help us here. The ESRI help has example scripts in C# and Vb.NET that could be converted to Python using the comtypes module as demonstrated by Mark Cederholm.

http://help.arcgis.com/en/sdk/10.0/arcobjects_net/conceptualhelp/index.html#//0001000002w1000000
This could be made into a simple script or module that would do the zooming for us until 10.1 arrives.
An excellent little example of extending ArcPy using ArcObjects.

The tracking number for this enhancement is NIM060058. The plan is to have it in 10.1; however, it is too early to guarantee inclusion at this point.

Has anyone converted Kimos link
http://help.arcgis.com/en/sdk/10.0/a...000002w1000000
To a Python script?

I'm sure many of us can use this conversion.

Thank you, Aaron

Jeff,

We are on Arc10 SP2 now and I am not seeing enhancement NIM060058 in the "issues addressed" page:

http://downloads2.esri.com/support/downloads/other_/ArcGIS-10sp2-issues.htm#desktop-sp2

Do you know if this got passed over, or am I just not seeing it, etc....

Thanks,

At 10.1 there is a arcpy.mapping.ListBookmarks() function that provides a list of names and extents.

Here is a help topic sample. If you join the beta community you'll be able to try out so much more of the arcpy.mapping functionality that was added at 10.1.

ListBookmarks example 2
Similar to example 1, the following script will loop through each bookmark in the Transportation data frame, set the data frame extent, and export the data frame to a JPEG file.

import arcpy
mxd = arcpy.mapping.MapDocument(r"C:\Project\Project.mxd")
df = arcpy.mapping.ListDataFrames(mxd, "Transportation")[0]
for bkmk in arcpy.mapping.ListBookmarks(mxd, data_frame=df):
    df.extent = bkmk.extent
    outFile = r"C:\Project\Output\\" + bkmk.name + ".jpg"
    arcpy.mapping.ExportToJPEG(mxd, outFile, df)
del mxd

This functionality is great!
Is it also possible to create a polygon shapefile from all the bookmarks in the mxd?
Because I also want a map with the overview, indicating al the "squares" of the different bookmarks.
Does someone know how to do it?

Thanks a lot!!

Can anyone please help?
Maybe someone from esri? Or should I email the helpdesk?

Thank you!

You can build the polygons from the bookmark extents using the Polygon class. Check out the following help topic/sample:
http://resources.arcgis.com/en/help/main/10.1/#/Polygon/018z00000061000000/

Also, check out the 4th example in the arcpy.mapping DataFrame class help. This also creates a polygon feature.

Annelies,

Great idea for a sample, and good timing...I just wrote a script that will do this:

import arcpy, os

# The map with the bookmarks
mxd = arcpy.mapping.MapDocument(r"C:\Project\BookmarksToFeatures.mxd")

# The output feature class to be created -
# This feature class will store the bookmarks as features
outFC = r'C:\Project\BookmarkFeatures.gdb\Bookmarks'

# A template feature class that contains the attribute schema
# E.g. a "name" field to store the bookmark name
template = r'C:\Project\BookmarkFeatures.gdb\Template'

if arcpy.Exists(outFC):
    arcpy.Delete_management(outFC)
arcpy.CreateFeatureclass_management(os.path.dirname(outFC),
                                    os.path.basename(outFC), 
                                    "POLYGON", template, 
                                    spatial_reference=template)

cur = arcpy.da.InsertCursor(outFC, ["SHAPE@", "Name"])
array = arcpy.Array()
for bkmk in arcpy.mapping.ListBookmarks(mxd):
    array.add(arcpy.Point(bkmk.extent.XMin, bkmk.extent.YMin))
    array.add(arcpy.Point(bkmk.extent.XMin, bkmk.extent.YMax))
    array.add(arcpy.Point(bkmk.extent.XMax, bkmk.extent.YMax))
    array.add(arcpy.Point(bkmk.extent.XMax, bkmk.extent.YMin))
    # To close the polygon, add the first point again
    array.add(arcpy.Point(bkmk.extent.XMin, bkmk.extent.YMin))
    cur.insertRow([arcpy.Polygon(array), bkmk.name])
    array.removeAll()

Hi Jeff,

Would it be possible to modify your bookmarks script to reference individual FC tiles to make up a reference type index using a similar process?

Regards,

Craig
