The goal of this workshop is to cover the basic steps and considerations for creating a GIS based on a historical map and historical address data. We will use ArcGIS 10.2 to create the GIS. We will also use OpenRefine — a free, open-source text refiner — in order to clean the data that we will geocode.
Specifically, this workshop will cover: - Importing and georectifying a scanned map raster image into ArcGIS; - Adding a base map layer to the Table of Contents; - Digitizing streets based on the historical map; - Adding fields to the Table of Attributes; - Editing the Table of Attributes to add address ranges, street names and districts; - Using OpenRefine to clean data (that will eventually be geocoded) - Creating an address locator; - Geocoding addresses from an Excel sheet.
