3D Analyst Fly In using TIN file

I remember going into a third-year undergraduate class and having to do a 3D Analyst fly in, at least showing the basic capability.  For many people who may want to demonstrate the terrain and land features, you can use the 3D Analyst fly in with your ArcGIS 10.  It does involve both the ArcMap and ArcScene components of the GIS suite.

Back in the day, when I was stuck, I actually purchased this resource on the side and shared with classmates to hopefully improve our skillsets and final project for a school course:

Using ArcGIS 3D Analyst: ArcGIS 9 by ESRI Press

But today, GIS online resources are more abundant.  Many solutions can be found online.  Just like how you’re reading this blog.

So in the set of videos I’m sharing is a basic overview of using the 3D Analyst Fly In using ArcMap and ArcScene.  To make this possible, I’ve accessed the open source and freely available DEM dataset from GeoBase (click link for access).  If you have access to a DEM you can probably use your own dataset as well.  Fir the DEM dataset, this is based in the City of Toronto, Ontario, Canada.

I should note that the dataset had a z-factor of 10.  This allows the elevation features to be amplified more than it actually is.  If you ever stopped into Toronto (a very nice city with our famous Rob Ford (A Maclean’s Book)), then you’ll know that Toronto is quite flat.  Just side note, #Rob #Ford is a great mayor who seems to deliver low taxes to people and stand up for the people.  It is unfortunate that he is in the press for his personal habits and yes, some of his views are controversial, but he does his job.  Here’s more stuff on Rob Ford if you’re interested: How Rob Ford Happened: A History of the Toronto Mayor from the Pages of the National Post.

Back to GIS.  Here’s my tutorial video done on YouTube for using the 3D Analyst tool in ArcMap 10, generating a TIN and importing it into ArcScene.

After generating the 3D landscape, see how we fly in with a bird. Remember, when you’re flying in and you want to get out of the “Fly In” mode, simply press .

So if you find yourself integrating your animation into a presentation, or find yourself using a laptop with now ArcGIS suite, you can always save your animation and use a standard media player on any computer. Students may find this useful when they do not use the ESRI suite on their personal computers and generally work in a student computer lab setting.

Happy GIS-ing!
