How can I read a blob field from a feature class using python

[HarishSangireddy]

Hi,

I am trying to read the intensity values stored as blobs in the multipoint feature class that I created from a LAS file. I could not find a possible way to read it directly.  Please help..

Thanks

Was this ever resolved??  I am trying to do a similar thing with a HANSEN table

The only way I know of to directly read a BLOB field with Python is through ArcObjects and comtypes. There are some functions in ArcObjects that can read some types of BLOB data like intensity values. In your case I think you would need to be familiar with the binary data structure used by Hansen, so whatever the solution is it would likely not be easy.

For creating intensity rasters from LiDAR derived multipoints (the original poster's question) take a look at: http://blogs.esri.com/Dev/blogs/geoprocessing/archive/2009/05/12/Lidar-Solutions-in-ArcGIS_5F00_part...
