commonly used vertical datums
28
a synthetic rendering of locations from the curved earth surface onto a flat map surface
map projection
29
a type of projection that is positioned at the poles. distortion increases when away from poles, and it can't show more than half the world.
planar projection
30
a type of projection where distortion increases away from the standard parallel, and is good for mid-altitude areas
conic projection
31
a type of projection where distortion is greatest at the poles, and is good for low-altitude areas
cylindrical projection
32
a type of map distortion that preserves the shape of the map
conformal property
33
a type of map distortion that maintains areas in the correct relative size
equivalent property (equal area)
34
a type of map distortion that maintains accurate distance
equidistant property
35
a tool used to characterize, or visualize, the distortion that occurs on a map projection
tissot indicatrix
36
A U.S. *Conic* map projection that uses the Equivalent property, meaning it maintains area in correct relative size
Albers Equal Area Conic
37
A U.S. *Conic* map projection that uses the Conformal property, meaning it maintains accurate shape
Lambert Conformal Conic
38
A U.S. *Cylindrical* map projection with 60 zones, where each zone is only accurate for areas within it
Universal Transverse Mercator (UTM)
39
Large scale map projection with 124 Geographic zones designated for specific regions in the U.S.
State Plan Coordinate System
39
a file with one or more maps and related items. stores connections to spatial data, but not actual spatial data
map projection file
40
vector data that stores the location, shape, and attributes of geographic features
shapefiles
40
a folder that stores one or more feature classes, rasters, and other related files
geodatabase
41
Manage the data, maps, and results of a project. Browse and find datasets to add to your map. Record, view, and manage datasets and ArcGIS documents. Define, Export, and import .gdb data models and datasets
Uses of the catalog window and ArcCatalog
42
to remove a file: right click them, [____] them as a layer
delete file
43
the move a file: [___] above or below other shapefiles in a map
drag file
44
to move a file between projects: [___]
copy and past file
45
opening the attribute table shows us the ____ view.
data
46
the ____ view is hte same as the map frame
layout
47
how to access toolbars in ArcGIS pro?
selecting the toolbox tab in catalog pane
48
How to add data into ArcGIS Project
catalog pane > folder > create folder connection > double click data to be added
49
How is portability a reason to store relative pathnames?
when you use relative paths, you can easily move your entire project and associated data to a different folder or computer without having to update the data source paths manually.
50
How is collaboration a reason to store relative pathnames?
if multiple users are working on the same project from different locations, using relative paths can simplify data sharing.
51
How is project organization a reason to store relative pathnames?
relative paths can keep your project files organized and make it easier to manage file references
52
when you see _____ next to layers in TOC, it indicates there is an issue or problem with those layers.
red exclamation points
53
the (!) may appear if ______, meaning data has been moved, deleted, or if the path to the data has changed
Data Source Unavailable
54
represents longitude
Y
55
a symbol that represents latitude on a graph
X
56
why is measuring distance or area using a geographic coordinate system not a good idea?
distortion, degrees do not equal a certain distance, the earth's curvature, lack of Projection
57
Building blocks and components of coordinate systems, in order
Earth > geoid > spheroid/ellipsoid > datum > geographic coordinate system > projected coordinate system
58
____ allows us to represent the Earth as a 2D surface and make measurements on flat maps
projection
59
how is a projection performed?
a formula is used to convert from 3D GCS to 2D PCS
60
a projection can also be called ______
a developable surface
61
how does ArcGIS Pro calculate distance for layers with projected coordinate system?
The distance between any two features is calculated as the shortest separation between them, that is, where the two features are closest to each other. This logic is applied by any geoprocessing tool that calculates distance, including tools such as Near, Generate Near Table, and Spatial Join (with CLOSEST match option)
62
the distance of the minimum length inside the figure path
Geodesic distance
63
the straight line distance
Euclidian distance
64
the process of determining geographic coordinates for place names, street addresses, and codes
Geocoding
65

GEOID
67
When you use the ______ tool, the attributes from all features will be in the output
intersect
68
When you run the _____ tool, only the input feature's attributes will be in the output
clip
69
numbers which uniquely identify geographic areas.
FIPS
70
state-level FIPS codes have ___ digits
two
71
county-level FIPS codes have ___ digits
five
