ArcGIS - ESRI
All geographic datasets have GCS but not PCS (T/F) - ANS-TRUE
ArcGIS can perform an on the fly projection if the PCS does now not healthy with different layers
(T/F) - ANS-TRUE
Describe a conformal projection - ANS-Preserves local shapes and angles
Good for topographic maps, navigation charts, climate maps
Describe a equal vicinity projection - ANS-Preserves vicinity
Good for dot density maps, thematic maps
Describe a equidistant projection - ANS-Preserves distance from one or two precise points to all
different factors at the map
Good for maps of airline distances, seismic maps showing distances from earthquake
Describe upkeep with area? - ANS-If a map preserves region, then the scale of a function on
the map is the same relative to its length on the earth. On an same vicinity map, in case you
draw a shape and circulate it around the map, no matter in which you vicinity it, its length can be
the identical.
Describe preservation with path? - ANS-Direction, or azimuth, is measured in levels of attitude
from north. An azimuthal projection preserves course for all immediately traces passing thru a
single, designated region. On an azimuthal map, instructions from one vital location to all
different points at the map might be proven successfully.
Describe renovation with distance? - ANS-If a map preserves distance, then a line between one
factor at the map and any other is the same distance as it's miles on this planet (taking scale
into attention). Most maps have one or lines of real scale. An equidistant map preserves
authentic scale for all immediately lines passing thru a unmarried distinctive location. For
instance, if the map is focused on Moscow, a linear measurement from Moscow to any other
factor on the map might be correct.
Describe renovation with form? - ANS-If a map preserves form, then shapes, together with
outlines of nations, appearance the same on the map as they do on earth. A map that preserves
shape is known as "conformal." On conformal maps, compass guidelines are proper for a
constrained distance around any given area.
Describe the distinction between a paper map and a GIS map - ANS-GIS maps are dynamic
, You can manipulate the functions of a GIS map, you can not change the functions of a paper
map
This includes zoom, choosing capabilities you desire to peer, and get right of entry to a
database for more features
How is a GIS map prepared? - ANS-A GIS map includes 1 or extra dataframes
A information body is a set of layers
A layer is a group of capabilities
A feature represents a actual-world object
Is Earth vertically or horizontally squashed? - ANS-Vertically
Name 5 fashionable projections that can be categorized based on spatial properties they hold -
ANS-Conformal
Equal Area
Equidistant
Azimuthal
Compromise
Two methods you could map density using characteristic values? - ANS-One manner is to divide
the attribute values via the place of each polygon feature (i.E. Records normalisation)
Another manner is to accomplish that visually by means of using symbology to represent
quantities of factors within the real international (like a dot density map)
What are equal intervals? When need to you operate it? How many lessons ought to you use? -
ANS-It is much like a ruler, with an c language among every elegance is identical
Use whilst you want all training to have the identical range
For classes, select a range of that produces an easily understood c programming language (2,
5, 10)
What are 4 simple types of spatial relationships? - ANS-Distance
Containment
Intersection
Adjacency
What are lines of longitude called? Latitude? What angles are they measured at? -
ANS-Longitudes are meridians and latitudes are parallels
Longitude coordinate represents a line at the high meridian and a line extending east along the
equator
Latitude coordinate represents a line at the equator and a line extending north along the 60
meridian
What are manual? When have to you operate it? How many classes ought to you operate? -
ANS-Each elegance has a range that you specify
