SPATIAL ANALYSIS EXAM 2 INCLUDING FULLY
ANSWERED QUESTIONS FOR EXAM PREP
model - ANSWER An abstraction of reality. A simplified representation of
some real-world phenomenon.
automate and document your spatial analysis and data management processes.
automates workflows - ANSWER what is modelbuilder?
to see a visual representation of analysis and geoprocessing operations, to
automate and manage geoprocessing workflows, to run a complex succession of
processes an one tool, to plug in extra tools and parameters as needed, to share
geoprocessing workflows with other users - ANSWER why create a model in
modelbuilder?
variables, tools, groups, connectors - ANSWER what are the model elements?
variables - ANSWER either data or value
iterator, logical tool, tool - ANSWER what are the different types of tools?
data variable - ANSWER is input or output (derived)
groups - ANSWER are visual categories that include other elements in the
model
connectors - ANSWER can be a simple data connector, an environment setting,
a precondition, or feedback
a tool, its input data, and its derived data - ANSWER a single model process
represents what?
not ready to run, running, and has been run - ANSWER what are the different
states that model processes have?
,not ready to run - ANSWER when model elements are gray
ready to run - ANSWER model elements that are displayed in color
already run - ANSWER the shadow, or shading, behind a model element
application level - ANSWER set in environments; applied to all tools
tool level - ANSWER set in each individual tool dialog box; pertains to that
tool only
model level - ANSWER set in model properties; pertains to tools within that
model
model process level - ANSWER set in each model process
What is the goal of the model you want to build, what data do you need to use
in the model, what is the most effective workflow to follow to achieve your
goals - ANSWER When you are performing a type of GIS analysis or
completing a data management project and you want to use ModelBuilder, you
should consider the following questions before you begin building your model:
-determine the scenario and criteria for analysis or data management, and set
goals for your model
-explore and gather necessary data, which may involve creating and editing data
-choose tools that will enable you to achieve your goals. choosing tools requires
that you thoroughly understand both your goals and the available tools
-build and run a model. by this time, you should have already determined
everything that you need to complete your model
-explore and refine the results of your model. - ANSWER modelbuilder
planning guidelines
intermediate data - ANSWER Any data in a process that did not exist before
the process existed and that will not be maintained after the process executes.
can identify problems before you run your tool - ANSWER what does
validating you model do?
, parameters - ANSWER the fields that have been used setting the model
elements, a tool property that you must determine before running the tool.
examples: input and output datasets, distances, and units of measure
they are a type of parameter exposed in a geoprocessing model that appears in a
model's dialog box and allows for input.
-setting model parameters is important if you are sharing your model with other
users. model parameters allow others to run the model from a tool dialog box
and add their own data or values as input - ANSWER what are model
parameters, and why is it important to set them?
first, validate the model because the validation will verify the data inputs and
other parameters. if any are invalid, you can fix them so that the model works. -
ANSWER if a colleague or another user sends you a model, what should you do
first with the model and why?
Set the input data element as a model parameter. With the buffer distance, you
would first need to create a variable from the distance parameter and then set it
as a model parameter. - ANSWER Suppose that you want to send your parcel
owner notification model to a GIS analyst in another city. The analyst will run
the model as is, but they want to add the city's own parcel data and buffer
distances. How might you set up this capability in the model before you send it?
The model-level setting would override the application-level setting in the
hierarchy. - ANSWER If you set an application-level environment setting, and
then you set a model-level setting for the same environment, which environment
setting would override the other?
becomes the default setting after being set; is applied to any tool executed -
ANSWER what are the override characteristics of application level?
applied to a single run of a tool; overrides application-level settings -
ANSWER what are the override characterisitics of tool level?
overrides tool-level and application-level settings - ANSWER what are the
override characteristics of model level?
