GEOG215 FINAL EXAM PART 2
If you were attempting to query land use data and want your results to include land use that are either residential or commercial which SQL query would you select?
"Land-Use='Residential or "Land Use"='Commerical
Describe a real-world geocoding process:
-Targeting products sold by a state specific to zip codes.
3 Components necessary in order to geocode are:
1. Obtain Reference Data, Determine address locator style, and build address locator.
In order to create an inset map in ArcMap, what would you have to do first?
Add a new data frame
The address locator style called "US addresses-dual ranges" has which of the following characteristics?
Address range for both sides of the street segment
Dissolve Tool
Aggregates features based on specified attributes.
Location-based services
Applications and websites that provide services or information websites that provide services or information based on one's location.
Geocoding
Assigning geographic coordinates to map features, such as street addresses or zip codes.
Which US census enumeration unit is the smallest in both area and population?
Census Block
Merge Tool
Combines multiple input datasets of the same data type into a single, new output dataset. This tool can combine point, line, or polygon feature classes or tables.
Union (Analysis)
Computes a geometric union of the input features. All features and their attributes will be written to the output feature class.
Select the one element of a topological relationship that would allow you to determine the fastest route (which streets are to follow) in order to get from JMU to Washington DC?
Connectivity
Attribute Table
Contains Info, About a layer/feature
Buffer Tool
Creates buffer polygons around input features to a specified distance.
When adding XY data to arcmap, what format must the latitude and longitude values be in?
DBase Format
After selecting a feature on a map, what steps would you need to take in order to create a new, standalone shapefile of the selected feature?
Data->Export Data
Georeferencing
Defining an image's existance in physical space.
If you were to enter # values with decimal places into a shapefile's attribute table, which field type would you select?
Double
Raster Overlay
Each cell of each layer references the same location. That makes it well suited to combining characteristics for numerous layers into a single layer
Geoprocessing
Execution of a sequence of operations on geographic data to create new information
Stand Alone
Exists independently of a geodatabase set.
Clip Tool
Extracts input features that overlay the clip features.
An attribute table is not part of a shapefile.
False
GIS is unique because of its ability to create a map.
False
In a raster data model, cell size waries throughout the image.
False
State FIPS codes are not unique for each individual US state.
False
TIGER/Line data cannot be used to geocode addresses.
False
The American factfinder website allows you to download tabular data in a format which is immediately ready to be added to the map document and joined to a shapefile.
False
The append geoprocessing tool creates a new output file at the end of the process.
False
The many-to-one rule of carnality does not allow allow the join processes in ArcGis to function properly.
False
The shapefile vector file format supports topology.
False
What are the two overlay procedures?
Feature Overlay and Raster Overlay
When creating control points during the georeferencing process, you must create the control points in which order?
From the scanned image (JPG) to the reference layer (shapefile)
Digitizing
Geoprocessing tool in which a user 'traces' data from an image in a geographically different way.
List 3 out of the 5 components of GIS
Hardware, Software, and People
The vector data model is:
Ideal for representing features that're individually identified.
Which of the following statements is false about the joining process in ArcMap.
It's a permanent relationship.
GIS was first developed for use with what discipline?
Land Use Management
Which of the following tools should be used if you have 2 files that you would like to make into one file?
Merge
Which field would normally not be found in raster data model's attribute table, such as DEM?
Name
SQL
Programming language used for getting information from and updating a database.
Which one of the options listed below is not considered one of the three steps to digitizing?
Project the data
Which of the selection methods would you use in order to answer the following question:Which states start with the letter Mi?
Select by attribute
Topology
Spatial Relationships that include adjacency, connectivity, and containment.
Which of the following features would best be displayed using the vector model?
State Boundary
Once you've created an inset map, what would you have to do within arcmap in order to see both your main map and your inset map at the same time?
Switch to layout view
Feature Overlay
The key elements are in the input layer, not the overlay layer. The overlay function, not the overlay layer.
What's one drawback of a raster data model?
The shape of a discrete polygon features are disabled.
An area field within an attirbute table of a shapefile will not automatically update after having used a geoprocessing tool, such as clip of dissolve.
True
Georeferencing is considered part of the preparation in the digitizing process.
True
Once a field has been added to an attribute table, you cannot change the field definition from one type to another (e.g. from text to float).
True
The primary purpose of the US census is to enumerate the population in order to apportion representation of the House.
True
Toponymy databases (also called geographic names databases) can be used to find the official spelling as well as the geographic location (lat/long of a feature).
True
Using a DEM, which spatial analysts function allows one to visualize what can or cannot be seen from a point, such as a tower
Union
Web2.0
User generated content + web as platform +rich user experience
Which overlay geoprocessing tool can only be used when the 2 input layers are both polygon features.
Viewshed
Overlay Tool
