Map Number Project Description
1Analysis of Areas in Greatest Need for
Preservation in Pennsylvania
These maps utilize an index scale of 0-9 to calculate environmental sensitivity and risk of urbanization in Pennsylvania. The first two indices are used to identify private land that demonstrates the greatest need for preservation.

Analysis of Impact of Maternity Ward
Closures in Philadelphia from
1996-2008
During the decade of maternity ward closures in Philadelphia, these maps catalog the evolution of birth density and the growth of the remaining facilities due to the closures.
3Analysis of Impact of
Maternity Ward Closures in
Philadelphia from 1996-2008
This project utilizes the point distance tool to calculate the Euclidian distance travelled by all Philadelphia mothers to Maternity Wards within the city.

Analysis of Impact of Maternity Ward
Closures in Philadelphia from
1996-2008A final recommendation was made for new Total Obstetric care facilities able to assist women with all needs during and after a pregnancy. The locations of these facilities were determined by areas with the greatest need, are underserved and have a high risk of complications.

Model of Travel Time and Cost for all
Appointments during a Low-income
Pregnancy
This project utilizes Network Analyst to calculate the total travel time and cost of a typical pregnancy of a low income, uninsured woman in Philadelphia. Public health clinics, public assistance office and WIC are utilized in this study and all trips rely on public transportation. The high time and monetary cost of decentralized care for low income uninsured women is evident in this study.
6New District
Allocation for County Assistance Offices in
Philadelphia
Two potential district allocations are explored, the first relies on shortest travel time to each facility, similar to Thiessen Polygon distribution, except using road networks. A second potential allocation is presented, which uses the number of residents below poverty as the friction for the establishment of districts. Districts with greater numbers of impoverished residents are smaller to better serve these clients.
7Comparing Three
Test of Spatial Dependency
Using the explanatory variables, percent vacancy and percent nonwhite to predict Median Home Value. Next a comparison of three tests of spatial dependency is used to determine which test best accounts for spatial autocorrelation in the dataset.
8Cost Savings of
Centralization of Univ. of Penn Vendor
Delivery System
Network Analyst is used to calculate the cost of fuel, fines, salary, and pollution saved by centralizing the vendor delivery system. This would result in less expensive contracts with vendors and decreased idling time on Penn’s campus.
9Vancouver Island: Interpolation of Ln(Mn) Values using Ordinary Kriging
Geostatistical Analyst, Spatial Analyst and 3D Analyst is used to create this interpolated surface of Log(Manganese) values for all points within the study area of Vancouver Island. Ordinary Kriging is used in this analysis.
Environmentally Sensitive Areas in Pennsylvania
Categorized as: Farms, Forests, Wetlands
Hillsides, Proximity to Hydrology
and Parks
Privately Owned Land in Greatest Need of PreservationAs Determined by the Degree of
Environmental Sensitivity and
the Risk of Urbanization
Areas at Greatest Riskof Future Urbanization
Determined by Slope and Proximity to
Development and Highways.
13 Maternity Wards Have Closed in Philadelphia between 1996-2008The Remaining Facilites have had to Absorb Significantly more Births.
The Density and Number of Philadelphia Births has not Declined During this Period.
Use of the Point Distance Tool to Measure Distance Travelled by Philadelphia Mothers to the Birthing
Facilities.
After 13 Facility Closures, the Average Euclidian the Average Euclidian Distance Travelled by Philadelphia Mothers increased 15%.
