What are four primary components of GIS explained in the "How a GIS works" section? -
ANS-Data
Software
Hardware
People & workflows
What is ArcGIS Online? - ANS-ArcGIS Online is a GIS that can be accessed over the internet
and it is a dynamic website.
What is a feature? - ANS-A representation of a real-world object on a map.
Define vector data model? - ANS-Spatial data used to define objects with distinct boundaries
(points, poly lines, polygons)
Define raster data model? - ANS-Raster data stores information about objects without distinct
boundaries in an array of individual cells organized into rows and columns.
List data file types used to store vector and raster data models. - ANS-Vector: Shapefile/CAD
Raster:TIFF/JPEG
What is an attribute? - ANS-Nonspatial information about a geographic feature in a GIS, usually
stored in a table and linked to the feature by a unique identifier
What is a metadata? - ANS-additional data about a feature/attribute
ex: who collected data, where its referenced, usage constraints
What is a layer? - ANS-references GIS data that represents real-world features.(same theme,
geometry, and set of attributes.)
What is a scale? - ANS-Scale is the relationship between the size of a feature on a map and
the actual size of that feature in the real world.
What are the map elements (regarding map layout). - ANS-Title
Scare bar
, North arrow
Name and date
Legend
When performing attribute query, what are the components of query expression? Give an
example of query expression and name each component. - ANS-Attribute field
Operator (=, >, <, >=, And, Or)
Attribute value
(Price>1500)
When performing location query, what are 4 main types of feature location relationships? -
ANS-intersect
near
adjacent
inside
What is a "Home" folder regarding ArcMap? - ANS-the folder location where your map
document is stored and is the location that is initially used to add new layers to ArcMap and to
store new datasets
What does "storing relative pathname to data source" mean? - ANS-It stores incomplete paths
that are relative to the current location of your file that makes it easier to locate
What is the file name extension for map document? What is contained in the map document? -
ANS-The file name extension is .mxd for map document.
In the map document contains display properties of the geographic information that you work
with in the map (ex: properties and definitions of your map layers, data frames, and the map
layout for printing)
What are two views in the ArcMap? What is the purpose of each view. - ANS-The two views are
data view and layout view.
Data view is used to display and use map layers. This view hides the map elements and allows
you to focus on the data in a single data frame.
The layout view is used design and author a map for printing , exporting, or publishing.
Map document (.mxd) - ANS-A map used in ArcMap that is stored as a file on disk.
Layer - ANS-A map layer defines how a GIS dataset is symbolized and labeled (i.e., portrayed)
in your map views. (same theme, geometry, and set of attributes.)
