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.

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%.
