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
