DOQ data for Maine

The \GIS\me\doq directory contains digital orthophotos of Maine. Most images can be accessed through a layer file - the easiest way to view these photos is to add the M:\GIS\ME_base.lyr file to ArcMap.

Uncompressed NAIP is available from the Regional GIS Coordinator. NAIP imagery here is compressed at approximately 10:1.

There are many more orthos available for Maine through their discovery service.

Description

Source date
File Geodatabase containing georeferenced photos of the Cove Brook area from 3 time periods, 1930's, 1960's and 1998. multiple years
DMR_DOQs.gdb
File Geodatabase containing raster catalogs of DMR low tide imagery for parts of Muscongus Bay, Penobscot Bay and various locations Downeast; 2004-2005. Used for delineating eelgrass beds by DMR. 2004-2005
ME_index.gdb Contains an index layer of ortho imagery for Maine, with date of acquisition; from MEGIS. Maine GeoLibrary Orthoimagery Project. Orthoimagery Regional Catalog Footprint Index. Spatial extent: State of Maine. Temporal extent: 1996 - 2018. This footprint index includes all Maine GeoLibrary orthoimagery catalog holdings categorized as "regional" within the spatial and temporal extent specified. Collections from multiple sources/sensors. Spectral bands may be either one, three or four most in 8 bit unsigned integer form. Native pixel size may range from 0.075 meter to over 10 meter depending on collection source. Complementary raster services from which these vector data have been derived may be accessed Maine GeoLibrary Data Catalog Imagery or, these services may also be accessed directly from most GIS/CADD clients or programmatically by connecting Maine Orthoimagery Regional Aggregate Service . 1/31/2020
