Joining tables is a very important feature in ArcView because data needed for analysis may be contained in two tables.
Surfaces are better types of data layers to be used for continuous data than features because because every point on the Earth has a specific temperature elevation rainfall etc. associated with it.
A layer data file differs from a shapefile because a layer file retains its symbology properties and a shapefile does not.
Data frame properties differ from layer properties because data frame properties affect all of the data layers in a data frame and layer properties only affect a particular layer.
In creating overlays a union differs from an intersect because a union contains overlapping and non-overlapping areas from each data set.

Orthorectification differs from rectification because orthorectification uses elevation data to account for the natural variation in the Earth’s surface.
When performing orthorectification geocorrection properties must be entered with regard to the camera used for data collection because cameras or sensors have a certain amount of error or discrepancy related to them.
When orthorectifying an image it is best to select control points that are not clustered together because the portion of the image where the control points are located would be closely aligned and the rest of the image would be highly distorted.
When orthorectifying an image with a geographic extent that extends beyond one quarter quadrangle of area you may need to mosaic the digital elevation models (DEMs) to use for the analysis because the geographic extent of the elevation data must be at least that of the study area.
Specifying a larger seed radius in Seed Tool Properties typically causes a larger polygon to be drawn because the seed radius specifies the number of pixels that can be used to establish the range of pixel values that will be used to draw the polygon.
Clicking a single pixel rather than dragging a box when using the Seed Tool typically causes a smaller polygon to be drawn because the number of pixels used to build the pixel value range would be smaller.
A resolution merge can greatly enhance an image because it can use the real color of a low-resolution image to enhance a monochromatic high-resolution image.

When dealing with multimodal network datasets evaluators may need to be assigned for certain cost attributes because
Best Route analysis in the same geographic area may result in more than one route identified because the route may differ based on the cost attribute used for the analysis.
Layer Properties for analysis layers in network analysis differs from Layer Properties of data layers not involved in network analysis because analysis Layer Properties deal with properties related strictly to the network analysis being performed.
The Best Route in a network using miles as the cost attribute will always be the same as the Best Route in the same network using kilometers as the cost attribute because regardless of the unit of measure the best route using distance as the cost attribute is the same.
The Best Route in a network using time as the cost attribute will not always be the same as the Best Route in the same network using miles as the cost attribute because depending on the speed limit on streets in the network the shortest distance may not be the quickest route.
Route layers generated from network analysis must be exported as a new data layer in order to be used in other project applications because the route analysis data layer is stored only in the map document that is created in unless it is exported.
In order to model restricted access streets in a network values may need to be changed in the appropriate restriction field because Network Analyst only recognizes traffic flow direction of restricted streets in relation to the direction the data layer was digitized.

Which of the following scenarios best illustrates a barrier that could be used in network analysis? Closed street
Which of the following scenarios best illustrates a restriction that could be used in network analysis? One-way street
Which of the following is not a good example of a scenario that could benefit from the Reorder Stops to Find Optimal Route option in network analysis? Determining the routes of ambulances to multiple incident locations
In order to properly model real-world traffic flow barriers must be used in analysis because barriers represent real world situations such as closed streets or other scenarios that affect traffic flow.
Multimodal network datasets must be created using a geodatabase because multiple network data layers are needed to create a multimodal network dataset.
Best Route analysis in the same geographic area may result in more than one route identified because the route may differ based on the cost attribute used for the analysis.
Layer Properties for analysis layers in network analysis differs from Layer Properties of data layers not involved in network analysis because analysis Layer Properties deal with properties related strictly to the network analysis being performed.
The Best Route in a network using miles as the cost attribute will always be the same as the Best Route in the same network using kilometers as the cost attribute because regardless of the unit of measure the best route using distance as the cost attribute is the same.
The Best Route in a network using time as the cost attribute will not always be the same as the Best Route in the same network using miles as the cost attribute because depending on the speed limit on streets in the network the shortest distance may not be the quickest route.
Route layers generated from network analysis must be exported as a new data layer in order to be used in other project applications because the route analysis data layer is stored only in the map document that is created in unless it is exported.
In order to model restricted access streets in a network values may need to be changed in the appropriate restriction field because Network Analyst only recognizes traffic flow direction of restricted streets in relation to the direction the data layer was digitized.
A route from a facility to an incident location may differ from the route returning to a facility location from an incident location because restrictions concerning travel direction of streets and barriers may result in a different route.

Joining tables is a very important feature in ArcView because data needed for analysis may be contained in two tables.
Surfaces are better types of data layers to be used for continuous data than features because because every point on the Earth has a specific temperature elevation rainfall etc. associated with it.
A layer data file differs from a shapefile because a layer file retains its symbology properties and a shapefile does not.
Data frame properties differ from layer properties because data frame properties affect all of the data layers in a data frame and layer properties only affect a particular layer.
In creating overlays a union differs from an intersect because a union contains overlapping and non-overlapping areas from each data set.
A query performed using the Definition Query in Layer Properties differs from a Select by Attribute query because only the features meeting the query criteria will display in the map.
Different map projections are used for different GIS projects because spherical coordinate systems are the best systems to use for GIS analysis.
Using degrees for distance measurement in GIS analysis is not recommended because degrees of longitude differ because they do not have constant distance between them as you move from equator to pole.
Measurements taken in GIS analysis may differ based on the coordinate system and map projection used because different map projections have different degrees of distortion.
Measurements taken in GIS analysis may differ based on the coordinate system and map projection used because different map projections have different degrees of distortion.
A shapefile differs from a geodatabase because a shapefile can contain a single feature class and a geodatabase can contain multiple feature classes.
Map elements such as a legend scale bar north arrow etc. are needed for a map layout because otherwise the data contained in the map cannot be fully understood.
