Orthophotography

Maine GeoLibrary Ongoing Aerial Photography Program - 2012 update!

The Maine GeoLibrary, in cooperation with the Maine Office of GIS, has begun its 5-year orthoimagery program. In 2012 the focus will be on Cumberland and York Counties, funded by baseline grants from Maine DOT, Maine EMA, the Maine GeoLibrary, USGS, and Cumberland County. To date over 30 towns have opted to add funds for buy-ups. Download and read our project briefing which includes buy-up costs. We also have a PowerPoint which compares various orthoimagery products.

Now available:

2012 flight price list (Cumberland and York Counties, partial Androscoggin and Oxford)

2013 flight price list (Androscoggin, Kennebec, Sagadahoc, Lincoln, Knox, Waldo Counties)

2014 flight price list (Hancock, Washington, and southern Penobscot Counties)

The deadline for commitments in York and Cumberland counties is March 8, 2012. For all others, commitments are due by Dec 31 of the year prior to the collect (i.e. Knox County would need commitment by 12-31-2012 to be collected in Spring of 2013).

BACKGROUND

Maine GeoLibrary Ongoing Aerial Photography Update Proposal

People across Maine use spatially-referenced aerial photography (known as orthoimagery) for professional and personal uses every day. The information must be current and high quality to be useful. Therefore, the Maine GeoLibrary is proposing an ongoing orthoimagery update program with two levels of detail and varying update cycles. The proposal divides the state into groups of towns with the timing of updates being determined by the estimated rate of change and development. All organized towns would be covered by 2 foot resolution orthoimagery and all unorganized towns by 3.3 foot resolution orthoimagery. The proposal recommends buy-up options for groups of towns so they could acquire better quality orthoimagery by contributing money. The cost for the statewide base program on a 5 year cycle is estimated to be 8 cents per acre for a total of approximately $450,000 per year.

The full proposal and appendices are available from the Orthoimagery Sub-group of the GeoSpatial Data Working Group, as are the Orthoimagery Basemap Specifications for Maine

Digital aerial orthoimagery with property lines, land elevation contours, fire hydrants and water mains in GIS.
