The whole enchilada!

ArcMap ArcInfo-lite. Full map creation and display capabilities with some fairly sophisticated geoprocessing capabilities.

ArcGlobe View or query a surface from multiple viewpoints, create realistic perspective imaging, examine the visual impact of building new structures, analyze atmospheric, surface, and subsurface pollution dispersion.

ArcScene

ArcReader Designed to share maps or geographic data over the internet or on designated LANs

ArcToolbox Geoprocessing via gui

ArcCatalog Geographic File Manager

ArcPad Integration of mobile mapping……gps data collection and integration with other geographic information

ArcScan Importing, editing, analyzing and converting raster image data

Becoming Familiar with the basic features of ArcMap

Class Assignment 1A: Create Map and Use tools to find information

Directions

I. Open ArcMap

II. Save file: Assign_1

III. Establish Coordinate System:I. Projected: NAD_1983_UTM_Zone_11N

IV. Add:I. States shapefileII. Counties shapefileIII. Cities shapefileIV. Airports Shapefile

V. Zoom to Washington, Idaho, Oregon

Class Assignment 1A:

Answer the following questions using identify, select and other ArcMap tools:

1. What is the population of Sweet Grass county, Montana?

I. 1990?

II. 2000?

2. How many farms were located in Tillamook county, Oregon in 1987?

3. Which state has the most crop acres? Washington, Idaho or Oregon?

4. What is the longitude/latitude coordinates of Bend, OR?

Class Assignment 1B: Move / Measure

Use the appropriate ArcMap tools and features to Answer the following

1. How many miles is it from Strasbourg, France to Freiburg, Germany?

2. How many meters is it from Freiburg, Germany to Millau, France?

3. What European city is at: Long: -8.478578 and Lat: 51.896583?

Class Assignment 1C: Select Features

Answer the following questions using identify, select and other ArcMap tools:1. Select and highlight the state with:

I. The most peopleII. The fewest peopleIII. The lowest rent

2. Select and highlight the province in Canada with:I. The largest areaII. The smallest area

3. Select and highlight in Mexico :I. The city with 91,453 peopleII. The highway that goes down the Baja

Demonstration 2: Query / Export

• There may be times when you don’t wish to display the full geographic extent of the existing layers……..utilizing the definition query tool allows you to focus on that for which you’re interested.

Class Assignment 2: Query / Export

DirectionsI. Open ArcMapII. Save file: Assign_2III. Establish Coordinate System:

I. Projected: NAD_1983_UTM_Zone_11NIV. Add:

I. States, counties, cities, airports, area codes, zipcodes shapefile

First: • Using the definition query tool and the data export function, create 6 unique shapefiles

that characterize only three states, Idaho, Washington, Oregon with the following attributes:

• State boundaries, counties, cities, airports, area codes and zip codes within those states.

Second• Open the attribute table for airports and cities and select the three largest of each.

Then create another layer from these selections and add to the current list of layersThird

• Remove the U.S. layers……keep only the three state layers.• Save as Assign_2:

Demonstration 3: SymbologyWhere analysis and art intersect

Class Assignment 3: Symbology

DirectionsI. Open Assign_2II. Save file: Assign_3

First: • Create a map that illustrates the population density of counties in Idaho,

Oregon and Washington. Second

• Highlight the airports in the region and create appropriate symbols that illustrate the relative size (total number of enplanements) for each airport

Third• Turn off the layers for the airports and population density above. Create

a proportional symbol that shows the percentage of males/females per county for the NW region.

Fourth• Turn off the males/females layer above. Add the FAF2 Data, query only

for the region, then display the highway freight flows.

Demonstration 4: Layout View and Map Export

Class Assignment 4: Map Layout / Export

Directions

I. Open new ArcMap project

II. Save file: Assign_4The governors of Nevada, Colorado, Arizona and New Mexico are worried

about future volcanoes and earthquakes affecting the residents and freight flows in their states and have asked you to use your geographic skills to assess risk to both people and freight flows.

Goal: Create a series of maps that illustrate the locations of past volcanic and earthquake activity relative to population density, airports and freight flow activity in these four states.

Assign: 4 Specifics

Via the query tool, create appropriate shapefiles for the four state region States, Cities, Counties, FAF2, Volcanoes, Quakehis, Urban, Airports

Apply symbols to illustrate population density (either by county, city or urban area) Apply symbols to illustrate freight flows Apply symbols to illustrate the major airports Apply symbols to illustrate volcanoes Apply symbols to illustrate earthquake (divide by time period)

In layout view, apply appropriate titles / legends / frame characteristics and export four map jpegs (250 dpi), corresponding to Earthquake vulnerability (2 maps)

One map for people, one for transportation

Volcano vulnerability (2 maps) One map for people, one for transportation

Demonstration 5: Geocoding

The process of taking information and assigning geographical coordinates. Street Address Zipcode X,Y coordinates

Class Assignment 5: Geocoding

Use two separate methods to geocode the potato processing locations in the pacific northwest:

Using x, y coordinates and the create feature class option in ArcCatalog

Using Geocode Address in the ArcToolbox Find out which addresses were not identified, locate them and

their x, y coordinates, export database table, edit missing x,yinformation, then create new feature class option.

Demonstration 6: Joining

Finding a common field between a feature database and a separate attribute table in order to display or conduct further geoprocessing.

Common Fields: FIPS Zipcode CRD State County

Class Assignment 6: Joining Data

Directions

I. Open new ArcMap project

II. Save file: Assign_6

• Context: United States• Add Counties Shapefile: Four Copies• Join each to the Soybean, Wheat, Corn and Potatoes files using the

FIPS field.• Apply symbols and create a production map for each, a consumption

map for each and the surplus/deficit map for each.

Demonstration 7: Buffer Analysis

It is often that we are interested in the proximity of one or more features to other features. Buffer analysis is one of the most common and basic geoprocessing activities.

Common Fields: FIPS Zipcode CRD State County

Illustrate the rail line abandonment analysis and the investment alternative (port of moses lake) studies.

Class Assignment 7: Buffer Analysis

DirectionsI. Open new ArcMap projectII. Save file: Assign_7

• Context: Mississippi River System• How many bushels of corn and soybeans are grown within 10 miles and 20

miles of the river?

• Add Counties Shapefile (two copies), River System• Join one county to Soybeans and one to Corn.• Create two buffers around the river, one 10 miles, one 20 miles.• Calculate the intersection of each buffer and the counties.• Add additional fields to each attribute table, calculate area and then

calculated the total bushels for each area.• Sum for the entire river system, then display and create (export) maps

Class Assignment 7: Buffer AnalysisContinuedDirections

I. Open new ArcMap projectII. Save file: Assign_7a

• Context: Mississippi River System• How many cities in each county are within 20 miles of the river?

• Add Counties Shapefile, cities, river• Create one 20 mile buffer around the river.• Calculate the intersection of the buffer and the counties and the cities.• Calculate the intersection of the two newly created buffers

(counties_intersect and cities_intersect).• Sum the field and add as a table to the current view.• Which county has the most cities within 20 miles of the river?• Create a histogram to put in the map.
