I would like to use the table to show my students which sensors / imagery product types can natively support the full range of mensuration operations with the given toolset.
Having the table icon's blank is impeding this.
I would like to confirm the order of the tools going across the top of the Capabilities of Imagery section of the " Making measurements from imagery" portion of the ArcGIS for Desktop help file
Making measurements from imagery—Help | ArcGIS for Desktop CBenkelman-esristaff
Solved! Go to Solution.
The installed help shows the following.
There must have been a glitch in the published Web Help.
As Cody already mentioned, we will make sure that it gets fixed for the next Web Help update.
Hi Dan - this is the table i'm talking about. In the line with Raster Type or raster product - shouldn't there be the tool icons going across ?
Kevin
Thanks for bringing this up - we'll get it fixed.
I'll plan to confirm with a follow up post, but I'm 95% certain the order of tools in the 7 columns should be the same as the order in the upper table; that is, first column should be
The Distance tool
...to last 2 columns being
Top To Shadow Height tool
Base To Shadow Height tool
In most satellite datasets, there is information about the time and also the angle to the sun - those values are necessary to make any measurements based on shadows. The last 5 raster types (Applanix through Raster Dataset) will not have sun angle information, so it makes sense that the columns for shadow based tools do not have a check mark
(Note I may be wrong about NITF, but I believe this would be a "maybe" not a "yes" checkmark --> that is, some NITF files will have the sun angle information and enable the shadow tools, but I'm pretty sure this is not a required component of NITF files). RADARSat won't support shadow measurements because radar is an active sensor, and you won't see (solar) shadows.
The fifth column should be Base To Top Height tool and it makes sense that this cell is blank for "Raster Dataset" - for that tool to work, you need a camera model, which will be present in the other raster types but not the Raster Dataset raster type. (I am once again suspicious that this is incorrect for some, but not all, NITF files)
I hope this is helpful.

Thanks Cody Benkelman, Dan_Patterson
