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 orthoimagery was collected in Cumberland and York Counties. This acquisition was funded by baseline grants from Maine DOT, Maine EMA, the Maine GeoLibrary, USGS, and Cumberland County. 22 communities opted to buy up to 6” resolution imagery and 7 towns purchased 3” resolution imagery. The town of York experienced a savings of $26,000 over a previous acquisition in 2005 for the same quality data.
In 2013 we are moving to central Maine and Mid-coast Maine, covering 5 counties and over $300,000 worth of imagery.

Would you like to participate? Contact State GIS Manager Michael Smith for more information michael.smith -at- maine.gov. 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).
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.
