Lab 2: Map Design and Coordinate Systems (40pts)
Name: Gwen Earnest
Instructions: Complete sections of Chapters 3 and 4 from Mastering ArcGIS Pro
Use this template for submission.
Chapter 3 Complete all the steps in the “Teaching Tutorial” section (starting on PDF page 246
). Answer
the two questions spread throughout the tutorial (contained in yellow boxes) and provide those answers below. (6pts)
1) A map is the projection of a specific set of data created by the mapmaker, while the map frame is the area on the layout in which the map will be designed and/or printed on.
2) Subdivision, division, division unit
Provide a 2-3 sentence summary of the teaching tutorial. This should include the key concepts and skills you learned through this assignment. (8pts)
This teaching tutorial creates a map layout depicting Pacific Northwest Volcanic Hazards in the states of Washington and Oregon. This map features volcanoes based on the number of eruptions in graduated size symbols between 1-10 eruptions, with major volcanoes named. This map also features population per county in terms of persons per square mile using graduated color symbols, with capital cities labeled. Interstates and highways have been included. There is also an
extent indicator for location reference, along with other map features such as a legend, scale bar, north arrow, and gridlines.
Complete the Practice Exercises starting on page 282
. You will be asked to create a map layout for this exercise. Save the map layout as a PDF and submit along with the rest of Lab Exercise #2 (10pts)
** Rather than use the World Terrain tile layer from ArcGIS online, I used the Terrain with Labels basemap from ArcGIS as it looked better and accomplished the goal of showing elevation and hillshade. It did add some unwanted labels such as mountain ranges and major rivers - sorry about that!

Chapter 4
Complete all the steps in the “Teaching Tutorial” section (starting on PDF page 321)
. Answer
the eight questions spread throughout the tutorial (contained in yellow boxes) and provide those answers below. (10pts)
1) WGS 1984
2) 80.4193381 degrees W 25.2019015 degrees N
3) Map units: degrees
Display units: decimal degrees
4) Meters (1.0)
5) Negative X and Negative Y: South America Positive X and Positive Y: Asia
6) Central meridian: -96.0
Latitude of origin: 40.0
Standard parallels: 20.0 and 60.0
7) No, Pro automatically added “_Project” to the data set name as it is stored in a different database
8) NAD 1983
Complete the Practice Exercises starting on page 361
. Provide answers and screenshots/captures to the exercise questions below. (10pts)
1)
Projected Coordinate System: NAD 1983 StatePlane Texas Central FIPS 4203
(US Feet) – Map units: US feet
2)
Lambert Conformal Conic
Standard Parallels: 43.0 and 45.5
Central Meridian: -120.5
Latitude of Origin: 41.75 (not equator)
3)
121°45'38"W 46°51'8"N
10T 594499 5189548
I couldn’t figure out how to get to Washington State Plane South, I don’t think
I did any of these right
Degree and decimal degree
4)
These projections create different standard parallels and central meridians which is responsible for the differences
5)
Standard parallels: 20.0 and -23.0
Latitude of Origin: 0.0
I do expect Africa to have some negative y values in this projection because the cone is centered on Africa
6)
It is a secant projection because there are 2 standard parallels. 7)
Africa Lambert Conformal Conic uses WGS 1984. North American Equidistant Conic uses NAD 1983 because it is better suited for focusing on North America rather than the whole world
8)
Amarillo, Texas: State Plane Zone would be better
Pensacola, Florida: Falls right on the edge of the two zones, UTM would be better
State of Tennessee: State Plane Zone would be better

9)
Map is currently displaying in North America Equidistant Conic coordinate system. Cannot figure out how to “make it better” ☹
10)
Off leash areas have an unknown coordinate system. Off leash boundaries are currently in NAD 1983 UTM Zone 13N, in the NAD 1983 GCS and Transverse Mercator projection. Arteries are in the NAD 1983 StatePlane Texas Central FIPS 4203, in the NAD 1983 GCS and Lambert Conformal Conic projection, so I will match the layers to this one. Changed map to NAD 1983 StatePlane Texas Central FIPS 4203 (US Feet). Boundaries need to change geographic coordinate system to GCS NAD1983, areas needs to change projected coordinate system to NAD 1983 State Plane.
