Deck 14: How to Perform Spatial Interpolation With Arcgis

Question 1

Describe the steps involved with designing a 3D structure in SketchUp and then placing it into its correct location in Google Earth.

Answer 1

In SketchUp,you can first acquire a "snapshot" of aerial imagery to use as a base for modeling a real-world structure.This "snapshot" will contain information that can be used to reference the model into its real-world coordinates.After creating the structure with SketchUp,it is exported to a KMZ file and placed into its proper spatial location in Google Earth.

Question 2

Pre-made 3D objects in SketchUp refer to

A)components.
B)prisms.
C)georeferences.
D)faces.

Answer 2

A

Question 3

A 3D-style choropleth map is a(n)

A)prism map.
B)smartmap.
C)raised poly map.
D)omni-theme map.

Answer 3

A

Question 4

Viewing an image that is offset in both the color red and the color blue that enables a "3D" style effect is an example of

A)anaglyph.
B)GeoWall.
C)stereovision.
D)CityEngine.

Question 5

Which of the following operations would best allow you to place 3D buildings at their proper height on the terrain (e.g. ,the terrain is 900 ft above sea level,you want the building to sit on the terrain,not float above or below it)?

A)Extrusion
B)Offsetting
C)Applying base heights
D)Vertical exaggeration

Question 6

Which of the following operations would best allow you to model a feature such as creating a footprint of your house and showing the house at the proper height?

A)Extrusion
B)Offsetting
C)Applying base heights
D)Vertical exaggeration

Question 7

Describe the basics of how a GeoWall system enables the user to see images in stereoscopic 3D.

Question 8

In 3D design,elevation or height values are referred to with the letter

A)E.
B)H.
C)Y.
D)Z.

Question 9

Which of the following operations would best allow you to model a feature such as an elevated walkway joining two buildings over a busy city?

A)Extrusion
B)Offsetting
C)Applying base heights
D)Vertical exaggeration

Question 10

Graphics that can be applied to the faces of an object to provide a more realistic appearance are

A)smartshapes.
B)omni-objects.
C)textures.
D)links.

Question 11

Many 3D models are available to use in Google Earth and SketchUp via the

A)3D Hawaii.
B)3D Warehouse.
C)3D Buildings Layer.
D)3D Thematic Mapper.

Question 12

Extruding a polygon will turn it into a

A)block.
B)line.
C)multipatch.
D)wall.

Question 13

KML and KMZ files are the native file formats used to work with 3D objects in

A)SketchUp.
B)Google Earth.
C)ArcScene.
D)ArcGlobe.
