ArcGIS Exam II questions with correct
answers
What is spatial analysis? Answer✔✔ The process of examining locations,
attributes, and relationships of features in spatial data through overlay and other
analytical techniques in order to address a question or gain useful knowledge.
What types of studies can be performed using spatial analysis? Answer✔✔
Proximity Analysis (police stations), Suitability Studies (retail), Risk Assessment
Studies (flood prone areas), Gravity Models (city pools and distance)
Describe a Suitability Study. Answer✔✔ Create centroids of police beats; buffer
the police beat centroids; buffer retail businesses; select major streets and buffer
them then dissolve the common overlap to combine the areas.
How can spatial joins be used in conjunction with geoprocessing tools to solve
problems? Answer✔✔ Spatial joins can use polluting companies (points) next to
geographic data and proximity buffers to water sources.
What is the difference between union and intersect? Answer✔✔ Union combines
all the polygons from the input whether they overlap or not. Intersect only contains
features that fall within the spatial extent of overlayed polygons.
What does union/intersect do to the non-spatial data? Answer✔✔ Intersect doesn’t
include it. Merge incudes all of it.
What is geoprocessing? Answer✔✔ Managing and or analyzing data in order to
form decisions or solve problems.
What are the major geoprcessing tools? Answer✔✔ Clip, Dissolve,
Append/Merge, Union, Intersect, Buffering
What is a clip? Answer✔✔ Cookie cutter; only keeps the features/attributes
associated with the clipped area.
What is the difference between clip and select by location? Answer✔✔ Select by
location leaves dangled edges. Clip gives a clean cut.
What does dissolve do? Answer✔✔ Aggregates: Puts like attributes together.
Features based on specified values like all counties in one state have the same state
name. State populations can be aggregated by the sum of all of the counties
dissolved.
What is a merge? Answer✔✔ Adds one layer to an existing layer. A new layer is
created from the two that were combined.
What is an intersect? Answer✔✔ Use when you want to overlay a layer with the
polygons in another layer so that the resulting output layer has the combined
attribute data of the features in the two inputs and only contains features that fall
within the spatial extent of overlay polygons.
What is a union? Answer✔✔ An overlap of feature classes including attributes.
Use when overlapping two polygon layers so that the resulting output layer has the
combined attribute data in the two inputs and contains all the polygons from the
inputs whether or not they overlap.
What is snapping? Answer✔✔ An automatic editing operation where features
within a specified distance of other features are moved to match exactly with each
others coordinates.

name you chose
An ArcGIS Pro project can contain multiple views of the geometry of the data.
True/False Answer✔✔ TRUE:
When you use multiple views of your map, the underlying data and symbology are
the same but the angle or zoom might be different. Therefore, different aspects of
the map become more apparent.
Your project can also contain several different maps.
True/False Answer✔✔ TRUE:
If multiple maps that use the same data are required to perform a specific task, you
might want to keep all the maps in the same project. This capability is useful if you
want to symbolize layers differently or turn certain layers on and off.
ArcGIS Pro enables you to view your data side by side in 2D and 3D—a powerful
capability.
True/False Answer✔✔ TRUE:
2D map can be converted into a 3D scene. You can also construct a 3D scene from
scratch using the data associated with your project. Scenes in 3D can be shown in a
local, isolated context or on the surface of a globe.
ArcGIS Pro allows you to add new data or update features quickly and efficiently.

Raster Data Storage: Cell Size Answer✔✔ Cell Size (spatial resolution)
Cell size=length of one side of a cell in the real world
Higher (finer) vs. lower (coarser) spatial resolution
Spatial Resolution Answer✔✔ Resolution=Size of each cell
-Ex. 10m res. Means each cell represents a 10x10m square of the earth
Raster Data Model: Bands Answer✔✔ Think of a stack
RGB- digital cameras
Multi-band
Mixed Pixel Problem Answer✔✔ In remote sensing, a pixel whose digital number
represents the average of several spectral classes within the area that it covers on
the ground, each emitted or reflected by a different type of material. Mixed pixels
are common along the edges of features.
Raster Data Model: Spatial Reference Answer✔✔ Bottom-left Cell is start point
Referenced by center of cell
Inherent location
Raster Data Model: Types of datasets Answer✔✔ -Satellite Imagery: Landsat,
MODIS
-Aerial Imagery: Aircraft, USVs
-DEMs: USGS, LiDAR
-Land Cover: MRLC:NLCD(prod w satellite imagery)
-scanned files (old maps)
Raster Data Model: File types Answer✔✔ IMG, JPEG2000, ArcGIS grid, SID,
TIFF, many more
Raster Data Model: Structure Answer✔✔ Cell-by-Cell encoding
-encodes as full matrix
-best for unique values
Multi-band
