ArcGIS Exam II questions with correct
answers
What is spatial analysis? Answer\u2714\u2714 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\u2714\u2714
Proximity Analysis (police stations), Suitability Studies (retail), Risk Assessment
Studies (flood prone areas), Gravity Models (city pools and distance)
Describe a Suitability Study. Answer\u2714\u2714 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\u2714\u2714 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\u2714\u2714 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\u2714\u2714 Intersect doesn’t
include it. Merge incudes all of it.
What is geoprocessing? Answer\u2714\u2714 Managing and or analyzing data in order to
form decisions or solve problems.<\/p>\n\n\n\n
What are the major geoprcessing tools? Answer\u2714\u2714 Clip, Dissolve,

associated with the clipped area.
What is the difference between clip and select by location? Answer\u2714\u2714 Select by
location leaves dangled edges. Clip gives a clean cut.
What does dissolve do? Answer\u2714\u2714 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\u2714\u2714 Adds one layer to an existing layer. A new layer is
created from the two that were combined.
What is an intersect? Answer\u2714\u2714 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\u2714\u2714 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\u2714\u2714 An automatic editing operation where features
within a specified distance of other features are moved to match exactly with each
others coordinates.<\/p>\n\n\n\n

of maps<\/p>\n\n\n\n
-if you want to apply the same layout to the map series
When should you NOT use data driven pages (2)? Answer\u2714\u2714 -for a SERIES of
maps showing DIFFERENT elements in the SAME geographic area (eg different
species’ distribution in same park area)
-you are able to show the entire map area with sufficient detail (just use one big ‘ol

What is a page definition query (eg.)? Answer\u2714\u2714 a definition query that updates
as you navigate through the data driven pages series (eg. show only counties in
current detailed state (even though someof other states can be seen around detailed

ArcGIS Pro questions with correct answers
What is ArcGIS Pro? Answer\u2714\u2714 1) ArcGIS Pro allows you to view, edit, analyze
and share your GIS data quickly and efficiently
2) It uses ribbon-based interface and streamlined workflows.
3) ArcGIS Pro is also designed to be web-connected, so you can access
information stored online as easily as data that you have stored locally and then
share it online or locally with equal ease.
ArcGIS Pro: Template Answer\u2714\u2714 Starting without a template allows you to do
your work without having to create a project beforehand.
ArcGIS Pro: Project Answer\u2714\u2714 When you create a project, ArcGIS Pro will
generate a folder structure on disk, including a project file that stores projectrelated elements, such as maps, layouts, styles, toolboxes, and geodatabases.
ArcGIS Pro: Catalog pane Answer\u2714\u2714 expand the various folders to see the maps
and scenes, toolboxes, databases, layouts, styles, and folder connections.
ArcGIS Pro: Ribbon Answer\u2714\u2714 Ribbon across the top of the application and
several tabs. Here, you can add data to the map, make selections, manage a layer’s
appearance, or perform other tasks.
ArcGIS Pro is context-sensitive – what does this mean? Answer\u2714\u2714 Meaning that
when a data layer is selected in the Contents pane, different tabs become available
on the ribbon based on the specific characteristics of the selected layer.
In ArcGIS Pro, there are several options for viewing your data\u2026 Answer\u2714\u2714 1)
two different extents of the same map next to one another
2) view 2D and 3D representations of the data simultaneously<\/p>\n\n\n\n
What is native structure for ArcGIS Pro? Answer\u2714\u2714 Project:
A project consists of a main file with an APRX file name extension and an entire
folder structure designed to contain the project data. These folders contain maps,
layouts, tasks, toolboxes, styles, and connections to databases and folders.
Start ArcGIS promoted to open a project > name it > created in a folder with a
name you chose
An ArcGIS Pro project can contain multiple views of the geometry of the data.
True\/False Answer\u2714\u2714 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\u2714\u2714 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\u2014a powerful
capability.
True\/False Answer\u2714\u2714 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.<\/p>\n\n\n\n

What keyword does the Boolean connector use to intersect operation on sets?
Answer\u2714\u2714 “AND”
“AND” Boolean Operator: Answer\u2714\u2714 which specifies a combination of
conditions (A and B must be true)
