Cached Map ServicesThere are cached map services that display high resolution orthoimagery collected through Maryland’s Statewide Orthoimagery Program. Two of the cached map services (Six Inch Imagery 2007 - 2008 and Six Inch Imagery 2010 - 2011) display true color imagery for past imagery collection efforts. The 2017 (Western Shore) and the 2016 (Eastern Shore) true color imagery is displayed in the MD Six Inch Imagery Cached Map Service.
Image ServicesThe MD Six Inch Imagery Image Service displays the 2016/2017 4-band high resolution orthoimagery. Unlike cached map services, image services provide the user more control over how the underlying mosaic dataset is displayed. Among other capabilities, the user is able to modify the mosaic method used (e.g. Closest To Center, By Attribute, Seamline, etc.), the mosaic operator used (e.g. First, Last, Min, Max, etc.) and the band combinations used (e.g. 4,3,2 RGB) in order to achieve the appropriate display for a given task. The image service can be incorporated into web mapping applications or used in the desktop environment.
NAIP ServicesMD iMAP hosts several cached map services that display a statewide mosaic of leaf-on aerial imagery collected during the agricultural growing season by the National Agricultural Imagery Program (NAIP). The imagery is often used for estimating crop plantings and yields. MD iMAP hosts NAIP imagery map services for years 2005, 2007, 2009, 2011, 2013, 2015, and 2017.
