MAPPING RESOURCES (sorry about the in-class demo disaster!)
- Mapping Software:
- Smaller, Faster version of ArcExplorer -- that WORKS!
During installation, specify a new folder name such as 'Maps.' This will allow you to find data and map files later.Sample maps for World Countries and US themes are included in a DATA subfolder.
- ARCVoyager Software -- Get the 'Special Edition' -- Stand-alone ArcViewLITE. Windows and MacVersions!
Tutorials, Lessons, Prepared map 'atlases,' TONS of shapefiles and data tables, AND capability of doing mapping using ArcView interface.
- Data Table Editor
This is a simple .DBF editor to add your data to the map."Shape files" contain both geographic features (points, lines or areas) AND feature "Attributes" or thematic data.
When you locate a 'base map' ( a shapefile which has the outlines of your area features and/or locations of your points or lines), the shape file component map_name.DBF contains the attribute features database.
The important element of this table is the name-link between the data and the map features -- usually an abbreviation such as the Two-Letter State abbreviation: CA, NV, ...etc.
Other columns in the table contain the actual thematic data -- Population, Area, and so forth.
Unfortunately, rarely do we find a basemap that has all the attribute data that we need. SO...we usually have to EDIT the .DBF file to either manually enter our own data OR calculate a new column using existing data (for example, a new column 'Density' can be calculated by the formula/expression ' Population / Area'. Note: New column names should be <=8 letters, no spaces.
ALWAYS make a backup copy of the original file! Mistakes happen.
- Maps and Data
More Websites that offer free, downloadable shapefiles
(naturally, the caveat is that websites blink in and out of existence like semidemiquarks)
WebGIS US one degree data- DLG and DEMs
Practice Exercises and Graded ASSIGNMENTS MIGRATION -- In and Out of Your Country
Using the Data for Your Country, CALCULATE the following:
- Net Migration -- Which is more, in-migration or emmigration?
- Where do migrants go? Nearby countries? Former colonial powers?
- Where do immigrants (if any) come from?
- When and Where did people from your country emmigrate to the US?
- What time periods?
- Where did they settle?
- What is the distribution in the US like today?
- Population_Density[aka "Arithmetic Density"] = Total_Pop / Total_Land_Areakm
- Physiological_Density = Total_Pop / Arable_Land_Areakm
- SexRatio = ( Total_Male_Pop / Total_Female_Pop ) * 100
- FertilityRatio = ( M 0- 4 + F 0- 4 ) / F15- 44
- DependencyRatio = ( Pop 0-15 + Pop 65+ ) / Pop16- 64
The AGE-SEX Structure of Your Country
- Constructing a Population Pyramid
- Data Requirement: Males & Female Population by 5-Year Intervals
- Download the PopPyr Spreadsheet to your local disk
- Open the spreadsheet in MS Excel
- Replace the columns Male# and Female# with your country's data
- Open the Chart tab and view your Pyramid
- Customize the pyramid for your Country's Name
- Print your pyramid
- Use Print Preview to control printing
- Under Page Setup/Chart, select "Use Full Page"
- make sure the page setup is "landscape"
- Print to Paper
- Copy your pyramid for use as an Overhead Projector Transparency
- Bring to Class
