<p>Points = Represent buildings, sample plots, a tree, etc Lines = Used to represent roads, rivers, drainages, etc Polygons = Used to represent areas, ponds, stands, lakes, boundaries, etc Nodes = Intermediate points of a line</p> Signup and view all the answers

<p>Feature = A single entity of vector data with geometry and attribute data Feature Class = A group of features with the same geometry type Attribute = Data associated with a feature Field = A column in an attribute table</p> Signup and view all the answers

<p>Resolution = The dimension of the pixel size in a raster data Shapefile = A vector data format used to store geometric shapes Attribute table = A table containing associated data for a feature Record = A row in an attribute table</p> Signup and view all the answers

<p>Geometry = The physical representation of a feature Attribute data = Information associated with a feature Feature = A single entity of vector data with geometry and attribute data Vertex = An intermediate point of a polygon</p> Signup and view all the answers

<p>Spatial data = Data that is referenced to particular positions on the earth's surface Geodatabase = A collection of geographic datasets that are stored in a file system folder or a relational database management system Symbology = The use of symbols to represent the attributes and features of a map layer Metadata = Data about the data or information that describes items in GIS</p> Signup and view all the answers

<p>Contents pane = Lists all the layers and tables in the map or scene and shows how the features are represented Catalog pane = Allows access to all items associated with a specific project in one place .aprx = Project file that contains items you create in the project, such as maps and scenes .jpg = Image file extension</p> Signup and view all the answers

<p>Calculate geometry tool = Calculates the area, perimeter, or length of features Summarize data toolset = Contains tools that calculate total counts, lengths, areas, and basic descriptive statistics of features and their attributes Define projection tool = Overwrites the coordinate system information (map projection and datum) stored with a dataset Heads-up digitizing (HUD) = Process involves the user manually tracing geographic features from a digital image or map on a computer screen</p> Signup and view all the answers

<p>Layer = Stores the path to a dataset and other layer properties, but doesn't contain the actual data Point-of-event table = A tabular data structure where each row represents a specific point or event location Geospatial database = A set of digital base maps that describes the “geography” of the Earth’s surface Shapefile = A file type that must have a minimum of three file types: .shp, .shx, and .dbf</p> Signup and view all the answers

<p>Row selection = The row is highlighted in blue in the attribute table Feature selection = The polygon or other feature is highlighted blue on the map, and the record is also highlighted blue in the attribute table Layer selection = The layer is highlighted in the contents pane Data selection = The data is highlighted in the catalog pane</p> Signup and view all the answers
