arcpy.mapping.ExportToTIFF full georeferenced export problem

JelmerOosthoek

Hello,

I have two raster layers in my TOC of which the top one is semitransparent. They have the same size and extent. I would like to export this combined 'map' in it's full resolution.

My first attempt uses File > Export Map. First I set the Dataframe width to be the rasters width. Next in Export Map I increase the DPI until the exported image width is around the width of the rasters. When I export ArcGIS 10 SP3 crashes. This has worked for me with ArcGIS 9.3.

The second attempt is using python:
import arcpy
mxd = arcpy.mapping.MapDocument("mymxd.mxd")
outTIFFpath = "out.tif"
df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]
arcpy.mapping.ExportToTIFF(mxd, outTIFFpath, df, df_export_width=46070, df_export_height=28126, resolution=2642, world_file=True, geoTIFF_tags=True)

(the width of the rasters is 46080 and 46070 here is the best approximation I can get)

The problem here is that the exported TIFF isn't correctly georeferenced. The resulting map is mostly white 'nodata' around the raster. How can I make sure the MapDocument goes to full extent before I export?

Kind regards,

Jelmer Oosthoek

I have a similar Problem,
I tried exporting a geoTIFF series via Data driven pages, but the TIFFs are noch georeferenced correctly.
If I Mosaic them together I get doubles.

I exported it vial Python using this script:

mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd)[0]
for pageNum in range(1, mxd.dataDrivenPages.pageCount + 1):
   mxd.dataDrivenPages.currentPageID = pageNum
   arcpy.mapping.ExportToTIFF(mxd, r"C:\Projects\Test\page" + str(pageNum) + ".tif", data_frame=df, geoTIFF_tags=True)
del mxd
del df


maybe someone has a good idea.
greetings

David
