NYCZevRoss Spatial Analysis helped NYC DOHMH design and implement one of the largest air monitoring networks in the United States, the New York City Community Air Survey (NYCCAS). In the context of this work, we produced statistical simulations to evaluate bias in network design scenarios, helped develop statistical models to predict air pollutants and NYCCAS Reportwrote scripts to automate a variety of tasks such as statistical output for model validation and monitor scheduling.

We have helped NYC DOHMH to prepare several reports and other materials on air pollution patterns in New York City including reports on ozone, particulates and metals.

Climate Change in CaliforniaZevRoss Spatial Analysis was contracted by the California Department of Public Health and CSTE to help develop a series of environmental health indicators as part of the Centers for Disease Control-funded Environmental Health Tracking Network.

As part of this work we analyzed trends in more than 50 years of daily temperature Air Pollutiondata in California, identified populations vulnerable to sea level rise in the US and analyzed exposure and trend patterns in wildfires, traffic and heat susceptibility.

U.S. Centers for Disease Control and Prevention (CDC)

JuarezZevRoss Spatial Analysis worked with researchers at the US Center for Disease Control and Emory University to evaluate the relationship between a variety of exposure metrics (e.g., particulate matter concentrations, distances to major sources of traffic, total traffic within given distances) and respiratory health effects among school children in Juarez, Mexico. We conducted the multi-level modeling and prepared many of the graphics highlighted in the resultant paper in the American Journal of Respiratory and Critical Care Medicine.Air Pollution

Syringe exchange site exampleWe have worked extensively with researchers at Emory University on projects related to sexually transmitted disease and access to primary care in urban areas. In the context of these studies we used Python programming and GIS to compute network distances between study participant's homes and primary care centers. We used this data as inputs in the development of gravity-based models to generate measures of spatial access using different travel friction coefficients.

Natural Resources Defense Council (NRDC)

ZevRoss Spatial Analysis has worked with NRDC on more than a half-dozen health-related projects. We have contributed data analysis, Dengue Fever VulnerabilityAir Pollution Vulnerabilitygeographic analysis and web mapping to projects focused on respiratory health, lead emissions, global warming, dengue fever, pesticides, wildfires, water contamination and soil contamination.

In the context of our work for NRDC we have analyzed climate data from the National Climatic Data Center, air pollution data from the US Environmental Protection Agency's Air Quality Subsystem, wildfire data from the National Oceanic and Atmospheric Administration, crop data from the US Department of Agriculture and many other data sources.

Emerging Markets Group and
U.S. Agency for International Development (USAID)

As part of a US Agency for International Development contract to improve reproductive health in Armenia, the Emerging Markets Group contracted with ZevRoss Spatial Analysis to provide GIS support and training to the Armenian Ministry of Health and other government agencies.

In Yerevan, the capital of Armenia, Zev Ross delivered a series of presentations to public health officials on the value of geographic analysis in public health and conducted a multi-day training on the use geographic information systems in public health.
