1. Define geospatial data. The data that describes both
the LOCATION and CHARACTER-
ISTICS of spatial features (such
as roads, land parcels, and veg-
etation stands on the Earth's
surface.)
2. What is GIS? Geographic Information Sys-
tems is a computer system
for capturing, storing, query-
ing, analyzing and displaying
geospatial data.
3. Location-based services are probably the most Wikipedia defines Location
commercialized GIS-related field. Based Services (LBS) as infor-
mation and entertainment ser-
vices accessible with mobile de-
vices through the mobile net-
work and utilizing the ability to
make use of the geographical
position of the mobile device.
LBS services include services to
identify a location of a person
or object, such as discovering
the nearest banking cash ma-
chine or the whereabouts of a
friend or employee. LBS services
include parcel tracking and ve-
hicle tracking services. They in-
clude personalized weather ser-
vices and even location-based
games. They are an example

5. Define geometries and attributes as the two com- Geometric data describe the lo-
ponents of GIS data. cations of spatial features, which
may be discrete or
continuous.
Attribute data describe the char-
acteristics of spatial features.
6. Explain the difference between vector data and Vector data use points and their
raster data. x-, y-coordinates to represent
spatial features of
points, lines, and areas.
Raster data use a grid and grid
cells to represent the spatial
variation of a feature (such as
elevation or precipitation.)
7. Vector Data Model: Explain the difference between The georelational data model
the georelational data model and the object-based uses a split system to store spa-

The object-based data model
stores spatial data and attribute
data in a single system.
