Outline
1
Introduction to Geographic Information Systems
  • for Slavic Humanists and Social Scientists
2
What is a GIS?
  • System for storing and retrieving geographic information


3
What is GIS?
  • Visualize, analyze, display spatial data
4
What is GIS?
  • Tool for relating disparate resources to create new knowledge


5
Why use GIS?
  • Look for patterns in data that are otherwise hidden
6
Why use GIS?
  • Looking for patterns
    • Change in distribution of architecture over time

7
Why use GIS?
  • Looking for patterns


    • Distribution of readership
    • Literacy rates & demographics (employment, income, industry)
    • Linguistic trends
    • Distribution of library users
8
Why use GIS?
    • Looking for patterns…


    • Places of Anna Akhmatova


    • -What works did she write in each place?
    • -Does this provide any insight into her work?
    • -What other writers wrote about or in the same places?

9
Maps and GIS Details
  • Points


    • Places, houses, trees, thoughts…
  • Vectors
    • Roads, rivers, paths, fences…

  • Polygons
    • Areas, regions
10
Maps and GIS details
  • Coordinate systems
    • Geographic
      • Latitude and longitude based on equator
      • Not uniform distances
    • Projected
      • Preserves spatial distances
    • Just know that there’s a difference, and it can change how things look…




11
Maps and GIS details
  • Georeferencing
    • Converting an image (raster data) to something that is “tied” to the earth’s surface



12
Attributes and databases
  • What is your data about?

Attributes and databases
15
Sources for GIS-usable data
  • Geography Network
  • FreeGIS
  • RussianAtlas.net
  • Russian Federation Digital Data
  • Digital Chart of the World
16
Starting a GIS
  • Find a georeferenced map of interest (or georeference one)
  • Create new layers to display your data
  • Add attributes
  • Link attributes from a database to points/vectors/polygons on your map
  • Add (or create) additional layers as needed
