    Rate this question:

  • 19. 

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

    • A.

      Clipping features

    • B.

      Dissolving features

    • C.

      Inputting features

    • D.

      Resulting features

    Correct Answer
    B. Dissolving features
    Explanation
    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.

    • C.

      ArcToolbox

    • D.

      Reprojection Extension

    Correct Answer
    C. ArcToolbox
    Explanation
    ArcToolbox must be used to permanently reproject a data layer in ArcGIS. ArcToolbox is a collection of tools and functions that provide a wide range of geoprocessing capabilities in ArcGIS. It allows users to perform various tasks, such as data management, analysis, and conversion. Reprojecting a data layer involves changing its coordinate system to match the desired projection. ArcToolbox provides the necessary tools, such as the Project tool, to perform this task accurately and permanently.

    In order to display data from a table of longitude/latitude coordinates in ArcMap, what option must be used? 

    • A.

      Display X,Y Data

    • B.

      Geocoding

    • C.

      Geoprocessing

    • D.

      Georeferencing

    Correct Answer
    A. Display X,Y Data
    Explanation
    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.

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

    • A.

      Spheres

    • B.

      Coordinates

    • C.

      Datums

    • D.

      Ellipsoids

    Correct Answer
    C. Datums
    Explanation
    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."

     Locations of interest that can be taken with a GPS unit are called 

    • A.

      Waypoints

    • B.

      Markers

    • C.

      Routes

    • D.

      Bearings

    Correct Answer
    A. Waypoints
    Explanation
    Waypoints are locations of interest that can be taken with a GPS unit. They are specific coordinates or points on a map that can be marked and saved for future reference. Waypoints are commonly used in navigation to create routes, track progress, and plan trips. They allow users to easily navigate to specific locations or landmarks, making them an essential feature of GPS devices.

     In creating overlays, a union differs from an intersect because

    • A.

      a union can only be performed using polygon features

    • B.

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

    • C.

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

    • D.

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

    Correct Answer
    C. a union contains overlapping and non-overlapping areas from each data set.
    Explanation
    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.
