How do we get spatial data, and what can we do with what we get?
We have basic data for the countries of the world (tucked away on /acadproj/vol8/ which should be the R: drive in P302), but often we need more detail and other formats, and that can often be found online, for free... but not without certain difficulties in conversion to forms we can use. Consider the example of Colombia: a search for 'colombia gis' in google does produce a lot of hits (20K+...), and one of the first is http://www.gisdatadepot.com/catalog/CO/datalist.html ...which allows us to get a variety of layers ...but plunges us into complications of formats and compressed files and so on...
Still, this is what we need to conquer, so we might as well begin.
Here's what you say you need:
Matt: "number of McDonald's per country (shown with a gradiation)... another demonstrating the amount/percentage of land devoted to Beef/other meat production for McDonalds in certain countries (e.g., Brazil)"And here are some locations for basemaps and other GIS-related stuff:Dan: * Geographical maps of East Africa as a whole and in parts Countries: - Tanzania (most important) - Kenya - Uganda * Great Lakes Region * Lake Victoria * Maps of cities along the shore of Lake Victoria (e.g. Mwanza, TZ / Entebbe and Kampala, Uganda) * Maps of population change throughout Uganda * Maps of fishery locations * Maps of where the Maasai live right now - change over time? * Topographical maps of the region * Maps that show savanna, desert, forest, etc. (I forget what you call them)
Mina: " I am specifically focusing on the population of S. Korea in terms of gender, age group, and geographic categories. I would think I need a map of how the ratio of people differ from urban area to rural area. I haven't been able to find any demographic map but I have found detailed statistical data and graphs on Korean population."
Tom: "...a map of svalbardland, with as many of the islands included as possible"
John: "...data on the number of nuclear tests that have occured worldwide to be placed into a color graded map based on frequency. Also, numbers of the size of the nuclear / atomic stockpile for certain countries over time. In addition, data on the ecological effects of these blasts i.e. instances of radiation posioning post-blast over time, the size of certain plant/animal populations post-blast over time, etc."
Tom: q:\sval\svalout.shp(many of these constructed from data from http://www.libraries.psu.edu/crsweb/maps/)
Mina: q:\skorea\skorea.shp and q:\southkorea\sk1.apr
Corinne: r:\colombia\colombia.shp and r:\colombia\16x.apr
Dan: r:\tanzania\tanzania.shp and q:\tanz\17x.apr
Matt: r:\esri1\world\cntry00.shp (countries of the world)
John: r:\esri1\world\cntry00.shp and post-Chernobyl links
These maps provide the basics for entering data of various kinds, but your projects are so varied that it's difficult to give one set of instructions for everybody. There are some principles, however: you can add layers on top of the base maps, using geographic coordinates to locate and place points, lines, and polygons (that's 'vector GIS'); and you can add data to the .dbf files that lie behind the vector layers --by adding columns to the .dbf files, or by joining other .dbf files that have a common field (like an index number or code or character string that appears in both .dbf files).
There are lots of fiddly things to know and take into account when you're learning to use ArcView. One of them involves drive letter mapping, a FIRST STEP before beginning an ArcView session.
There are a number of ways to approach learning ArcView, and choosing among them is a matter of your time and specific needs. We have a collection of homebrew tutorials that are meant to help users get started and solve common problems, and ESRI has a superb online learning environment called ESRI Virtual Campus which features FREE beginning tutorials and not-free 'courses' for which we have password access. John Watkins of University Computing is the Administrator for passwords. And then there's 1:1 with me, to figure out solutions to your specific problems. And then there's scrabblin' at the coalface with your bare hands...
Another basic use of maps is to illustrate: you can capture screen images with PhotoShop and edit and save them in formats that can be put onto Web pages (.jpg and .gif images). Here are the steps: :
