2. Add-on software products that run with ArcGIS to enhance its capabilities are called

Extensions

Layouts

Tables

Extensions are add-on software products that run with ArcGIS to enhance its capabilities. These extensions provide additional functionality and tools that are not available in the core ArcGIS software. They allow users to perform specialized tasks and analysis, such as spatial analysis, 3D visualization, or data management. Extensions can be developed by Esri or by third-party developers, and they can be purchased separately from the core ArcGIS software.

Population

Telephone number

Population is an example of a quantitative attribute because it represents a numerical value that can be measured and compared. It refers to the total number of individuals or objects in a particular group or area. Unlike address, name, or telephone number, which are qualitative attributes, population can be quantified and analyzed using statistical methods.

16. The process of reducing the amount of detail in a layer by removing boundaries of areas with the same attribute value is called

Clipping features

Dissolving features

Inputting features

Resulting features

Dissolving features is the process of reducing the amount of detail in a layer by removing boundaries of areas with the same attribute value. This means that areas with the same attribute value are merged together, resulting in a simplified representation of the layer. Clipping features, inputting features, and resulting features do not involve the same process of reducing detail by removing boundaries with the same attribute value.

Display X,Y Data

Geocoding

Geoprocessing

Georeferencing

To display data from a table of longitude/latitude coordinates in ArcMap, the option "Display X,Y Data" must be used. This option allows the user to input the coordinates from the table and plot them on a map. It helps to visualize the spatial distribution of the data points based on their longitude and latitude values. Geocoding is the process of converting addresses into geographic coordinates, while geoprocessing involves analyzing and manipulating spatial data. Georeferencing is used to align geographic data to a specific coordinate system.

26. In creating overlays, a union differs from an intersect because

A union can only be performed using polygon features

An intersect can be performed on all data layers and a union cannot

A union contains overlapping and non-overlapping areas from each data set.

An intersect contains overlapping and non-overlapping areas from each data set.

A union differs from an intersect because a union combines the overlapping and non-overlapping areas from each data set, while an intersect only includes the overlapping areas. This means that a union will result in a larger area, as it combines all the features from both data sets, while an intersect will only include the shared features between the two data sets.

A shapefile can contain a single feature class and a geodatabase can contain multiple feature classes.

A shapefile can contain only point, line or polygon feature types but a geodatabase can use other geometric types.

A shapefile cannot be created in ArcCatalog but a geodatabase can.

A shapefile is the only data format that can be viewed in ArcCatalog.

33. The various models that are used to approximate the shape of the Earth are called

Spheres

Coordinates

Datums

Ellipsoids

Datums are the various models used to approximate the shape of the Earth. They provide a reference system for mapping and surveying purposes. While a sphere is a mathematical representation of a perfect round shape, coordinates are used to locate points on the Earth's surface. Ellipsoids, on the other hand, are mathematical models that better approximate the Earth's shape, taking into account its slight flattening at the poles and bulging at the equator. Therefore, the correct answer is "Datums."
