Viewshed Help - OFFSETA/Height

[SusanSmith]

Hey all,

Where do I input height/OFFSETA in order to run a viewshed analysis on a few poly point towers?  I have searched and read all I could of the different options available under 'Environment Settings' with no luck.  Was so much easier in 9.3 I felt.

Any assistance or a point in the right directions would be SO greatly appreciated.

Thanks!!

Hi!

You will need to specify these values within your point feature class.  You will need to add the field into the attribute table and define the values.  Make sure you use the exact field name so that it can be recognized by the process.

You can see the field names for each parameter that can be used in the following document:
Using Viewshed and Observer Points for visibility analysis

The follow steps comes from the 9.3 help:
