About the Atlas of Maine 2008

The Atlas of Maine 2008 was developed by students in Introduction to GIS and Remote Sensing, an interdisciplinary course in the Environmental Studies Program at Colby College. The goal of this project was to develop a series of maps highlighting the unique human and natural resources of Maine. The Atlas maps on this page emphasize "visual" GIS. To view student research proejcts that emphasize "analytical" GIS click here. To view the Atlas of Maine 2005 click here. To view the Atlas of Maine 2006 click here. To view the Atlas of Maine 2009 click here. To view the Atlas of Maine 2010 click here.

The maps were originally created in ArcGIS 9.2 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 42 x 48 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.

Coming Soon: The complete Atlas of Maine 2008 will soon be available as a single PDF document.

Carbon Sequestration and Major Population Centers in MaineCarbon Sequestration is an effective approach to controlling the deleterious effects of greenhouse gases,the principal agent of Climate Change. As trees grow they utilize carbon dioxide (CO2) in the production of biomass, sequestering it in living tissue and preventing it from being released into the atmosphere. Governments, businesses, and individuals are using carbon sequestration as a way to take responsibility for their own emissions. Created By Jeff Carroll ('08).

Fragmentation and Clearing of Maine Forest Habitats: The purpose of this map is to convey the extent of fragmentation in Maine's forests. I chose this particular area to show the immediate effects of logging roads and clear cutting on a local scale. The data were used to focus on current, cleared, and regenerating forest locations as of 2005. A raster layer from the National Atlas database of National Land Cover Data assesses the magnitude of forest fragmentation due to human activities. Roads were also included to emphasize the development of roadways as a cause of fragmentation. Created by Lindsay Dreiss ('09).

Impervious Surfaces of Maine: Impervious surfaces include objects like buildings, roads, parking lots, and other surfaces that water cannot pass through. Pervious surfaces are mainly natural areas, such as forests and wetlands, but can also include human-modified areas such as crop land. The spatial pattern of impervious surfaces is closely tied to that of developed areas and it can therefore be used as a surrogate variable for development. Created by Courtney Larson ('08).

Suitable Habitats for Wildlife and Conservation Areas in Maine: This map shows levels of wildlife habitat suitability in relationship to Maine's conservation lands. The habitat suitability values are based on 91 priority trust species of the U.S. Fish and Wildlife Service. The habitats for each species were mapped and ranked from actual sightings or by developing habitat suitability models reflecting environmental requirements for each species. Scores for each species were then added to derive the sum of scores for all species combined. Michelle Presby ('09).
