Getting Data Driven Pages to scale raster symbology from each page's current extent

JeffOlsenholler

I'm generating a country-wide atlas at the (U.S. equivalent) county level.  I'm auto-clipping the raster coverages to each county-equivalent.  All is fine and good, except that the rasters do not scale to the current display extent unless I go to layer propertieson each individual layer.  That's not a practical solution.

So, is there a python script that will both recalculate the stretch for every data page and then export each page as an appropriately named PDF file?  Or is there an ESRI patch that will address this refresh issue?

Thanks,
Jeff

Unfortunately arcpy.mapping can't work with the stretched renderer.  Rather than the raster being a permanent layer in the MXD, what if you tried adding and deleting it with each page? 

Below is a sample snippet of code from the arcpy.mapping DDP Class help topic that I modified to add/remove your raster between DDP pages.  It just requires that you save your raster out as a layer file.

import arcpy mxd = arcpy.mapping.MapDocument(r"C:\Project\ParcelAtlas.mxd") df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] rasLyrFile = arcpy.mapping.Layer(r"C:\Project\Data\Basemap.lyr") for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1):     mxd.dataDrivenPages.currentPageID = pageNum     arcpy.mapping.AddLayer(df, rasLyrFile, "BOTTOM")   #You can use InsertLayer for more precise placement        mxd.dataDrivenPages.exportToPDF(r"C:\Project\Output\Page" + str(pageNum) + ".pdf", "CURRENT")     arcpy.mapping.RemoveLayer(df, rasLyrFile) del mxd
