<p>In Spring 2019, with funding from several State partners, MassGIS contracted with the <a href='https://www.usgs.gov/' rel='nofollow ugc' target='_blank'>U.S. Geological Survey</a>
 for statewide, 15 cm resolution, 16-bit, 4-band (RGB-IR) digital 
orthophotos. The data were delivered in early 2020 as 10,218 individual 
1,500 m x 1,500 m tiles in a GeoTIFF format. To allow for easier 
distribution of this free imagery, MassGIS compressed the GeoTIFFS into 
the JPEG 2000 format, which retains the IR band. This hosted tile service was created
 using JPEG 2000 versions of the imagery.</p><p>Project specifications are based on the <a href='https://www.asprs.org/' rel='nofollow ugc' target='_blank'>American Society of Photogrammetry and Remote Sensing</a>
 (ASPRS) standards. The data were developed based on a horizontal 
projection/datum of NAD 1983 2011 UTM zones 18N and 19N meters and a 
vertical projection/datum of NAVD 88 (GEOID 12B) meters.</p><p>This 
digital orthoimagery was created to provide easily accessible geospatial
 data which are readily available to enhance the capability of federal, 
state, and local emergency responders, as well as to plan for homeland 
security efforts. These data also support <a href='https://www.usgs.gov/core-science-systems/national-geospatial-program/national-map' rel='nofollow ugc' target='_blank'>The National Map</a>.</p><p>These
 images can serve a variety of purposes, from general planning to field 
reference for spatial analysis, to a tool for data development and 
revision of vector maps. The imagery can also serve as a reference layer
 or basemap for myriad applications inside geographic information system
 (GIS) software and web-based maps.</p><p>For more information see the imagery's <a href='https://www.mass.gov/info-details/massgis-data-2019-aerial-imagery' rel='nofollow ugc' target='_blank'>MassGIS metadata page</a>.</p>
