2what is GIS?
An [blank_start]inform[blank_end]ation system that is designed to work with data referenced by [blank_start]spa[blank_end]tial or geographic [blank_start]coord[blank_end]inates. In other words, a GIS is both a database system with specific capabilities for [blank_start]spa[blank_end]tially referenced data, as well as a set of operations for working with the data.- Ainform

- Ccoord
- Dspa
3GIS as an "Approach to Sc[blank_start]ience[blank_end]"
- "Generic issues that surround the use of [blank_start]GIS[blank_end] technology impede its successful implementation, or emerge from an understanding of its potential capabilities.
- GIS is research on GIS with GIS- Aience
- BGIS
4GIS as a "[blank_start]So[blank_end]cial [blank_start]Sci[blank_end]ence"
- public participatory GIS
- volunteer GIS (VGIS)
"or[blank_start]ganiz[blank_end]ed activity by which people mea[blank_start]sure[blank_end] and represent [blank_start]geo[blank_end]graphic phenomenal, and then transform these representations into other forms while interacting with [blank_start]so[blank_end]cial structures"- ASci

5GIS is not...
- a [blank_start]glob[blank_end]al [blank_start]position[blank_end]ing system (GPS)
- a s[blank_start]tat[blank_end]ic map (click on the map)
- [blank_start]soft[blank_end]ware package- Aglob
- Bposition
- Ctat
- Dsoft
6Humans are spatial [blank_start]think[blank_end]ers!
- P[blank_start]tole[blank_end]my maps were "it" until the 1400s
-- Science does [blank_start]not[blank_end] occur in a cultural vacuum

9Humans are spatial thinkers!
- _____ is thought to have formulated hypothesis that cholera is spread through contaminated water supplies after creating and examining a map in the Broad street area of London in 1855
- Asnow
10what is a map?
- an [blank_start]ab[blank_end]stract representation of [blank_start]feat[blank_end]ures that occur on or near the [blank_start]earth[blank_end]'s surface
- an abstract representation of a known or unknown [blank_start]geo[blank_end]spatial process- Afeat
- Bab
- Cearth
- Dgeo
11Models of the earth
- [blank_start]ob[blank_end]ject view
- features are represented as "[blank_start]object[blank_end]ed"
- [blank_start]object[blank_end] or [blank_start]vec[blank_end]tor model
-f[blank_start]ield[blank_end] view
- features are represented as a continuous [blank_start]field[blank_end] of data or
observations
- [blank_start]field[blank_end] or r[blank_start]aster[blank_end] model- Aob
- Bobject
- Cobject
- Dvec
- Eield

12In ArcMap, all analysis is typically done in the
[blank_start]data[blank_end] view while map construction is done in the
[blank_start]layout[blank_end]- Adata
- Blayout
13MXD f[blank_start]iles[blank_end] save all the symbology and lay[blank_start]out[blank_end] elements of a map
- Ailes
- Bout
14An aerial photograph showing large parts of the United States is an example of the [blank_start]raster[blank_end] data model while a map of roads in Texas is an example of [blank_start]vector[blank_end] data model.
- Araster
- Bvector
15What is the general sequence of steps for adding a GIS data file (e.g. shapefile) into ArcMap?
- Start ArcMap -- Click Add [blank_start]Data[blank_end] -- Create Con[blank_start]nection[blank_end] to Folder (if a connection does not exist) -- Choose Connection to Folder -- Select File(s) -- Ad[blank_start]d[blank_end]- AData
- Bnection
- Cd
16Geodesy
making [blank_start]measure[blank_end]ments of the [blank_start]Earth[blank_end]- Ameasure
- BEarth
17shape of the Earth
- Early convention held that the earth is a [blank_start]spher[blank_end]ical object
- [blank_start]Equator[blank_end]ial bulging due to gravity > e[blank_start]llipse[blank_end] or oblate ellip[blank_start]soid[blank_end]
- not an ellipsoid either > odd shape > [blank_start]geo[blank_end]id- Aspher
- BEquator
- Cllipse
- Dsoid
- Egeo
18______ > odd structure caused by differential ____itational forces
- Ageoid grav
19__________ > to locate things consistently we need a mathematically clean graticule > latitude and longitude
- Aellipsoid
20- Distance between two successive [blank_start]long[blank_end]itudes is inconsistent as we go [blank_start]toward[blank_end]s the poles > measurements difficult
- measurements are easier in a [blank_start]plan[blank_end]ar coordinate system
- fit an ellipsoid over the geoid > not always accurate > [blank_start]dat[blank_end]ums- Along
- Btoward
- Cplan
- Ddat
21Datums specify the [blank_start]fit[blank_end]
- Afit
22 Projections
Sphere or > Azi[blank_start]muthal[blank_end]
ellipsoid > [blank_start]Cylin[blank_end]drical
> [blank_start]Con[blank_end]ic- Amuthal
- BCylin
- CCon
23Projections - Not to get off on a tangent!
- When a plane touches a 3D sphere, there is a s[blank_start]ingle[blank_end] point of tangency
- when [blank_start]cone[blank_end]s and [blank_start]cyl[blank_end]inders touch the sphere, there is a s[blank_start]ingle[blank_end] line of tangency
- SECANT: in this case we have a line with the plane and two lines with the cylinder and cone, these lines have zero distortion- Aingle
- Bcone
- Ccyl
- Dingle
24Projections- there is another aspect to this
- ASPECTS -
Sphere > Normal = [blank_start]po[blank_end]le / transverse = [blank_start]eq[blank_end]uator
cylindrical > Normal = [blank_start]eq[blank_end]uator / transverse = [blank_start]mer[blank_end]idian
conic > Normal = [blank_start]m[blank_end]id- [blank_start]lat[blank_end]itude / transverse = ?- Apo

25Projections- Properties
- a projection that preserves the shape of features across the map is called [blank_start]conform[blank_end]al
- a projection that preserves the area of a feature across the map is called [blank_start]eq[blank_end]ual area or [blank_start]equiva[blank_end]lent
- to compare or edge- match maps in a GIS, [blank_start]bo[blank_end]th maps [blank_start]mus[blank_end]t be in the same [blank_start]projec[blank_end]tion- Aconform
- Beq
- Cequiva
- Dbo
- Emus
- Fprojec
26Every projected coordinate system has a well-defined unit of measurement (e.g. meters or feet, etc.) associated with it.

[blank_start]Azimuthal[blank_end] is a type of developable surface whereas
[blank_start]conformal[blank_end] refers to a property that a projection may preserve or distort.- AAzimuthal
- Bconformal
28The term GCS refers to [blank_start]Geographic[blank_end] [blank_start]Coord[blank_end]inate [blank_start]System[blank_end] . It means that the spatial data are [blank_start]Unproject[blank_end]ed . The units of such data are typically defined as [blank_start]Deci[blank_end]mal [blank_start]Degree[blank_end]s.
- AGeographic
- BCoord
- CSystem
- DUnproject
- EDeci
- FDegree
29The [blank_start]projected[blank_end] tool is used to change the coordinate system in use by a GIS data file whereas the
[blank_start]define projection[blank_end] tool is used to specify missing projection information.- Aprojected
