network graphs,

geocoding,

& GIS

what we're doing

  • network graphs - what are they?
  • making a network graph using Google Fusion Tables
  • geocoding with Awesome Table & Google Sheets
  • mapping with ArcGIS Online

centrality

degree centrality

more friends = more important/influential

eigenvector centrality

more important friends = more important/influential

closeness centrality

information from the closest can spread to the network quickly - shortest paths to everyone in the network

betweeness centrality

information often flows through them - most short paths flow through them

let's make a network graph!

google fusion tables: go/fusiontables/

make sure you have added our table to your google drive!

geocoding

Break!

but first...

  • go to go/arcgisonline/
  • sign in "using Middlebury"
  • click on "groups" at the top of the screen, then "my organization's groups"
  • search for "HARC"
  • request access to the group!

mapping with ArcGIS online

First...what is GIS?

  • GIS stands for Geographic Information System
  • GIS is a tool used to capture, store, manipulate, analyze, manage, and present geographic data
  • The data used with GIS is spatial data (data that is referenced to points on the Earth)
  • GIS is not a map!

maps are made of layers

What are our possible layers?

  • basemap
  • locations of archaeological finds
  • locations of dealers/collectors
  • locations of museums
  • etc...

let's make a map!

ArcGIS Online: go/arcgisonline/
