Ephemeral Cities : From Page to Data Four steps to convert from image to data: 1) Page image processed by Optical Character Recognition [OCR] Engine to obtain text 2) Custom parsing software converts text into spreadsheets 3) Spreadsheets manually reviewed for errors and corrected 4) Corrected spreadsheets loaded into relational database

Ephemeral Cities : Map to Data

PAGE 65

Ephemeral Cities : Map to Data Four steps to convert from map image to data: 1) Map image is geo rectified, placing it in the larger geographic context of the world. 2) Individual features indexed from the map image 3) Features matched between maps from different years 4) Geographic data loaded into the growing database

PAGE 66

Ephemeral Cities : Map to Data Step 1: Map image is geo rectified, placing it in a larger geographic context. Establishes the relationship between page coordinates (i.e. x,y ) of a planar map of image with known real world coordinates (i.e. latitude, longitude ) Control points, points with known real world coordinates, are used during this process. Once complete, every point on the map corresponds to a real world coordinate point.

PAGE 67

Ephemeral Cities : Map to Data Step 2: Individual features indexed from the map image A new GIS point layer is added to the map. Each building is identified by placing a point feature on the map. Additionally, the following information is recorded: Street Number Street Location Description Block number and sheet number (if applicable)

PAGE 70

Ephemeral Cities : Map to Data Step 3: Features matched between maps of different years All the maps for a city are loaded into the ArcIMS GIS software. Fading between maps of different years allows assistants to visually identify buildings and features which are common between the different years. This building and feature information is saved so the data reflects that a feature which spans the map years appears only as one feature or building. For example, the Alachua Hotel in may be in the same building he Gainesville Hotel occupied in 1912.
