The maps were originally created in ArcGIS 9.3 and exported to the web using ArcIMS, an internet map server from ESRI. To view the maps using ArcIMS, click on one of the the links below. To view a map as a PDF document, click the PDF link next to the map description. The paper maps were originally created as 36 x 42 inch posters and reduced to 8.5 x 11 inches to faciliate download by PDF. Please note: The IMS and PDF maps are large files so it may take a few minutes to load unless you are using a high-speed internet connection. ArcIMS works well with Windows operating systems running Internet Explorer. MacIntosh OS X users may need Mozilla Firefox to open and view the dynamic ArcIMS maps.

Farm Size and Lymphoma Cancer in Maine: Lymphoma is a general term for a group of cancers that originate in the lymphatic system. The lymphomas are divided into two major categories: Hodgkin lymphoma and all other lymphomas, called non-Hodgkin lymphoma (NHL), which is displayed on this map. The annual incidence of NHL in Maine has nearly doubled over the last 50 years. Although the reasons for this increase are not certain, it has been established that pesticides are a known risk factor. Created By Aurore Anastassiadis ('11).

Distribution of Endangered Turtle Species in Maine: This map shows the ranges of the three endangered terrestrial turtles in Maine: the Blanding's, Box, and the Eastern Painted Turtle. These turtles are on the endangered species list for Maine and the U.S. All suffer from territorial fragmentation which is separating turtle populations making it hard to keep population growth sustainable. Most live in acidic wetlands or ponds in the southern part of Maine, which is the northern most part of their range in the U.S. Created by Meghan Cornwall ('11).

The endangered turtle species list came from Maine Department of Inland Fisheries and Wildlife ( The information on turtle ranges was found from the PEARL database ( The ranges of turtles that PEARL showed were based off of townships. Their data came from viewings by Maine citizens dating from 1976 to the present. The layers of the townships and of the rivers and streams in Maine were found off of the Maine Office of GIS website ( This map is projected using the North American Datum 1983, Universal Transverse Mercator Zone 19N coordinate system.

Atlantic Salmon Habitat and Dams in Maine: This map details Atlantic Salmon habitat within the state of Maine in conjunction with dams, levees, and other hydrological impoundments. It highlights salmon spawning and rearing areas, and represents dams by their hydraulic height. Most Atlantic Salmon populations are anadromous, living most of their lives at sea and migrating upstream into freshwater to spawn. However, the Atlantic Salmon does not require saltwater to survive, and there are a number of landlocked populations of Atlantic Salmon in Maine due to the building of dams. Created by Francis Gassert ('11).

Data for this map is available through the Maine Office of GIS website: Inset map data from ESRI Data & Maps 2000 (CD 1). The Atlantic Salmon habitat data was originally collected by staff of the Maine Atlantic Salmon Commission and U.S. Fish and Wildlife Service from field surveys conducted on the Aroostook, Dennys, Ducktrap, East Machias, Kennebec, Machias, Passagassawakeag, Penobscot, Pleasant, Presumpscot, Sheepscot, St. George, Tunk, Union Rivers, and selected tributaries. Surveying was conducted between 1994 and 2003. Impoundment data was originally collected by the U.S. Army Corp of Engineers (USACE) 1987 Dam Survey and by staff of the Maine Department of Environmental Protection (MEDEP), Bureau of Land & Water Quality (BL&WQ). It was most recently updated in 2004. Projected in Universal Transverse Mercator Zone 19N North American Datum 1983.

Medically Underserved Areas and Populations in Maine 2008: According to the Health Resources and Services Administration Shortage Designation Branch of U.S. Department of Health and Human Services, Medically Underserved Areas may be a whole county or a group of contiguous counties, a group of county or civil divisions or a group of urban census tracts in which residents have a shortage of personal health services. Medically Underserved Populations may include groups of persons who face economic, cultural or linguistic barriers to health care. These federal designations are supplemented by state designations which cover areas or populations that do not meet federal designation criteria. The Health Resources and Services Administration Shortage Branch also designates Health Professional Shortage Areas (HPSAs, not shown on this map) in the categories of primary care, mental and dental health. Created by Hannah Lafleur ('11).

Medically Underserved Areas and Populations data are available from Maine Office of GIS ( and were compiled by the Maine Office of Rural Health and Primary Care in 2008.

Hurricane Surge Inundation and Critical Resources in Maine: This map shows projected hurricane surge inundation, often referred to as storm surge, for hurricanes ranging in severity from Category 1 to Category 4 as well the locations of critical societal resources such as fire stations, hospitals, emergency management offices, and roads. Storm surge is caused by the force of a hurricane displacing water as it moves into shallower water. According to the National Hurricane Center, storm surge is responsible for 90% of hurricane-related fatalities in the US. ( In addition, the flooding caused by storm surge may hinder evacuation as well as incapacitate or reduce the capabilities of certain resources by flooding facilities or impinging on mobility. Created by Brian Lynch ('09).

Rabies in Maine: 1998-2008: This map shows the number, location and type of animals found with rabies by county in Maine for the entire decade. It displays the top four species found with rabies: raccoons, skunks, bats and foxes. These four account for 96% of positive cases in Maine. Rabies is a fatal disease of the central nervous system. It is deadly but uncommon in humans in the US. However, animals, especially wildlife, are very susceptible to carrying the disease. Tests are conducted every year by the Maine Department of Health and Human Services to ensure that rabies is not rapidly spreading since it is easily passed by fluids, or tissues touching broken skin or mucous membranes. In the past ten years, the DHHS found 1,236 positive cases of rabies in Maine. Created by Kaggie Orrick ('10).

The projection of the map is Universal Transverse Mercator Zone 19N North American Datum 1983. Data source for this map can be found through the website of Maine Office of GIS: The rabies data was originally collected from the Office of the Department of Health and Human Services, from their Health and Environmental Testing Laboratory webpage: The Inset map data was from the ESRI Data CD.

Sources of Drinking Water and Agricultural Chemical Use in Maine: This map shows the location of aquifers and public water supply wells in Maine. The location of cultivated lands is shown in green, while the percentage of cropland in each county that is treated with chemical fertilizers is represented by the gray shading of the county. All data are from the Maine Office of GIS, with the exception of the agricultural chemical data which was adapted from the USDA 2007 Agricultural Census. Created by Jordan Schoonover ('10).

The following layers were obtained from the Maine Office of GIS ( Cnty24 – counties, Aquifer Polygons – aquifers, Gomlc7 – land cover, Wells – public water supply wells. All categories in the land cover layer except for ‘cultivated land’ were removed. The counties layer was joined with a table showing the percentages of cropland in each county that were treated by fertilizer. These data were adapted from a map on the same topic created by the US Department of Agriculture for their 2007 Agricultural Census ( Online_Highlights/Ag_Atlas_Maps/Farms/ Agricultural_Chemicals_Used/07-M104.asp).
