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!

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/
