New to 3D Analyst/ArcScene Report this article as Inappropriate to us !!!Login to Reply

We just got 3D Analyst and I'm trying to learn how to use it.  My final objective is to create a fly through in arcscene that I can export into a format that can be viewed by non GIS users.  That aside I will start with some of my basic difficulties. 

1.  Why does my .img that looks good in arcmap look terribly grainy in ArcScene?
2.  Is there a measure tool in ArcScene?  I can't seem to find one.
3.  I want to bring in a .ecw into arcScene, that is about 900megs, but it won't load arcscene just dies. 

These are some of this issues I'm having.  Originally we used Google Earth Pro for fly throughs, but the aerial imagery was not current enough so that is one of the reasons why we opted for 3d analyst in this case.  Just curious, is this goal attainable?  Thoughts, comments and suggestions are all welcome.

1. Two things

First: The resolution of your image will automatically be changed to a lower quality resolution, in order to fix this, open the properties of your .img. Cllick on the base heights tab, under the statement "Obain heights for layer from surface" there is a button that says "Raster Reslution." Here you can increase the resolution of your .img.

Second: In the layer properties, go to the Rendering tab and select the checkbox "Shade areal features relative to the scene's light position. Also you can max out the bar from Low to high for "Quality enhancement for raster images."

I'm having the same problem with ArcScene. A satellite image that is at a good resolution when viewed in ArcMap becomes too blocky to discern any detail in ArcScene. The 'Raster Resolution' button under the base heights tab is greyed out though, so I can't use it. Adjusting the quality enhancement slider doesn't make any difference. Any idea what the problem might be?

In my case, I am interested in 3D visualisation of landscapes and digital terrain modeling.
I would put myself somewhere between a beginner and intermediate user, on the beginning of my career. I noticed that there is a "market gap" in my field when it comes to 3D GIS and interoperability with CAD, thats why I want to step towards it.

I found the Esri trainings on 3D Analyst and a book called "Introduction to 3D data: Modeling with ArcGIS 3D Analyst and Google Earth". Although I'm wondering if there are more material available on this topic?

Moreover, is ArcGIS sufficient at all, when it comes to:
creating 3D landscape visualisations on local and regional scale,
working with Sketchup or other 3D modelling software alongside ArcGIS (or others?),
rendering from ArcScene (is it even possible?)

Should I consider other sofwares as well?
