Answers Perfectly A+ Graded New Update
Define GIS CORRECT ANSWER>>>>a computer system for capturing, storing, querying,
analyzing, and displaying geospatial data.
Geospatial Data CORRECT ANSWER>>>>Data that describe both the locations and
characteristics of spatial features on the Earth's surface.
List the major categories of GIS activities. CORRECT ANSWER>>>>a. Geospatial data
b. Data acquisition
c. Attribute data management
d. Data display
e. Data exploration
f. Data analysis
Explain the difference between vector data and raster data. CORRECT
ANSWER>>>>Vector data displays location of spatial features utilizing lines and symbols of
typically discrete data types, while raster data displays are grid-based utilizing cells to show
spatial features of continuous data types.
, Which of the following features is a discrete (well-defined location and shape) feature?
CORRECT ANSWER>>>>Roads
Which of the following features is a continuous feature? CORRECT ANSWER>>>>Both
Precipitation and Elevation
Vector data are better suited for representing ________ features and raster data are better
suited for representing ________ features. CORRECT ANSWER>>>>discrete,
continuous
One can use both vector data and raster data in a GIS project. CORRECT
ANSWER>>>>True.
One would normally begin with ________ in a GIS project: CORRECT
ANSWER>>>>data acquisition
What is the difference between a geographic coordinate system and a projected coordinate
system? CORRECT ANSWER>>>>The difference between Geographic Coordinate
System from Projected Coordinate System is that GCS is used from spatial features utilizing a
sphere with angles while PCS allows for a 2d map and utilize plane coordinates.
What does it mean by "reprojection"? CORRECT ANSWER>>>>Reprojection adapts
one type of coordinate system of projected coordinates to an different coordinate system.
All layers to be used together in a GIS operation must align spatially. CORRECT
ANSWER>>>>True.
