GISP Exam Study Guide with Complete Solutions

Data exploration - Answer✔️✔️-Data-centered query and analysis

Dynamic Segmentations - Answer✔️✔️-A data model that allows the use of
linearly measured data on a coordinate system

Georelational data model - Answer✔️✔️-A vector data model that uses a
split system to store geometries and attributes

GeoSpatial data - Answer✔️✔️-Data that describes both the locations and
characteristics of spatial features on the earth surface

Object-based data model - Answer✔️✔️-A data model that uses objects to
organize spatial data and stores geometries and attributes in a single
system

Raster data model - Answer✔️✔️-A data model that uses a grid and cells to
represent the spatial variation of a feature

Relational Database - Answer✔️✔️-A collection of tables in which tables are
connected to one another by keys

Topology - Answer✔️✔️-A subfield of mathematics that when applied to
GIS, ensures that the spatial relationships between features are expressed
explicitly

Triangulated irregular network (TIN) - Answer✔️✔️-Composite vector data
that approximate the terrain with a set of nonoverlapping triangles

Vector data model - Answer✔️✔️-A spatial data model that uses points and
their x y coordinates to construct spatial features of points, lines and
polygons

Azimuthal Projection - Answer✔️✔️-One type of map projection that retains
certain accurate directions. Azimuthal also refers to one type of map
projection that uses a plane as the projection surface

Central lines - Answer✔️✔️-The central parallel and the central meridian.
Together, they define the center or the origin of a map projection

Clarke 1866 - Answer✔️✔️-A ground-measured ellipsoid, which is the basis
for the North American Datum of 1927 (NAD27)

Conformal projection - Answer✔️✔️-One type of map projection that
preserves local shapes

Conic Projection - Answer✔️✔️-One type of map projection that uses a cone
as the projection surface

Cylindrical Projection - Answer✔️✔️-One type of map projection that uses a
cylinder as the projection surface

Datum - Answer✔️✔️-The basis for calculating the geographic coordinates of
a location. An ellipsoid is a required input to the derivation of a datum

Datum shift - Answer✔️✔️-A change from one datum to another, such as
from NAD27 to NAD83, which can result in substantial horizontal shifts of
point positions

Decimal degrees (DD) system - Answer✔️✔️-A measurement system for
long and lat values such as 42.5

Degrees minutes seconds - Answer✔️✔️-A measurement system for long
and lat values such as 42 30' 00", in which 1 degree equals 60 minutes and 1
minute equals 60 seconds

Ellipsoid - Answer✔️✔️-A model that approximates the earth, ALSO called
spheroid

Equidistant projection - Answer✔️✔️-One type of map projection that
represents areas in correct relative size

False easting - Answer✔️✔️-A value applied to the origin of a coordinate
system to change the x-coordinate readings

False northing - Answer✔️✔️-A value applied to the origin of a coordinate
system to change the x-coordinate readings

Geographic Coordinate data base (GCDB) - Answer✔️✔️-A Database
developed by the US bro of Land Managment (BLM) to include long and
lat values and other descriptive information for section corners and
monuments recorded in the PLSS

Geographic Coordinate System - Answer✔️✔️-A location reference system
for spatial features on the Earths surface

GRS80 - Answer✔️✔️-A satellite-determined ellipsoid for the Geodetic
Reference System

Lambert Conformal conic projection - Answer✔️✔️-A common map
projection, which is the basis for the SPC system for many states

Latitude - Answer✔️✔️-The angle north or south of the equatorial plane

Longitude - Answer✔️✔️-The angle east or west from the prime meridian

Map Projection - Answer✔️✔️-A systematic arrangement of parallels and
meridians on a plane surface

Meridians - Answer✔️✔️-Lines of longitude that measure locations in the E-
W direction on the geographic coordinate system

NAD27 - Answer✔️✔️-North American Datum of 1927 which is based on the
clarke 1866 ellipsoid

NAD83 - Answer✔️✔️-North American Datum of 1983 which is based on the
GRS80 ellipsoid and has its origin at the center of the ellipsoid

Parallels - Answer✔️✔️-Lines of latitude that measure locations in the N-S
direction on the geographic coordinate system

Principal scale - Answer✔️✔️-Same as the scale of the reference globe

Projected coordinate system - Answer✔️✔️-A plane coordinate system that
is based on a map projection

Projection - Answer✔️✔️-The system used to transfer locations from Earth's
surface to a flat map.
