Fast food restaurants for the U.S. were extracted from the ESRI Business Analyst dataset, and overlaid with hospital locations. Hospitals with fast food restaurants in them were identified, and the distance from each hospital to the nearest fast food was calculated.

In this paper, I propose a new methodology for analysing landscape drawing methods using a GIS. The subject of my analysis is the genre of Japanese screen paintings known as rakuchu rakugai zu ¯ , created between the 16th and 18th centuries. Rakuchu rakugai zu ¯ provide bird’s-eye views of the then-capital city of Kyoto, including buildings, natural features, and human activities. The methodology introduced here uses GIS spatial analysis functions to scan the painting surface onto a survey coordinate grid based on the relative positions of landmarks in the painting. The analytic sequence is as follows: (1) derive coordinate values for landmarks both on the painting and on a survey coordinate grid; (2) generate a link table from these two point-data sets; (3) use the projective transformation and rubber sheeting techniques to project the painting surface onto the survey coordinate grid; and (4) project the areas of the rubber sheet-derived polygons onto the painting. This process gives visual representation to differences between real space and the depicted space. Results show that rakuchu rakugai zu ¯ painted in the seventeenth century
and later distorted real space more than those painted in the sixteenth century, indicating a decrease in adherence to conventional perspective-based painting.

The CGA developed materials to geographically represent the genetic history of Harvard Professor Henry Louis Gates Jr., for the PBS documentary African American Lives 2, segment The Past Is Another Country. A portion of this program featured Ben Lewis of the CGA, discussing and demonstrating the mapping he created with Dr. Gates.

County level data on male and female life expectancy for the years 1961 - 1999 was obtained from the U.S. Census Bureau and the CDC’s National Center for Health Statistics. CGA helped the researcher create an animated map showing female life expectancy through this time period for Washington State.

This free workshop was intended for Harvard faculty, student, staff and affiliates in all disciplines who are interested in assigning geographic location to digital information. The workshop was designed to introduce the general concept and broad scope of georeferencing; explain why georeferencing is useful to many disciplines; explore common issues and challenges, and exchange methodologies, standards, and achievements.
The workshop primarily focused on georeferencing of digital records in museums, libraries, data archives and research collections, which includes gazetteer building, geo-tagging unstructured text, and address geocoding. It left out raster image georeferencing and global positioning systems from its panel discussions. Below are the presentations.
