Satellite imagery from Planet Labs was available, but does not provide high enough resolution for mapping without being used in conjunction with other imagery. Horizontal positional accuracy is based upon orthorectification of scanned aerial photography using USGS digital orthothophoto quadrangles for horizontal control and USGS 30m DEM data as vertical control. Horizontal RMSE for individual flightlines was held to less than four meters. none Digital imagery is georectified and orthographically corrected to produce a seamless series of aerial mosaics following the standard operating procedures (SOP). ERDAS IMAGINE Photogrammetry image processing software is used to orthographically correct the individual flight lines using a bundle block solution. Camera lens calibration data is matched to the image location of fiducial points to define the interior camera model. Control points from USGS DOQQ images, National Agriculture Imagery Program (NAIP), Virginia Base Mapping Program (VBMP), MD Six Inch, and ESRI World imagery provide the exterior control, which is enhanced by a large number of image-matching tie points produced automatically by the software when IMU data were not available. The exterior and interior models are combined with a 10-meter resolution digital elevation model (DEM) from the USGS National Elevation Dataset (NED) to produce an orthophoto for each aerial photograph. The orthophotographs area combined into mosaic datasets for each flightline which are then combined into a single Bay-wide mosaic dataset. 2024 Kevin Coyne Maryland Department of Natural Resources Chief, Geospatial Information and Analysis 410-260-8985 410-260-8835 410-260-8759 Tawes State Office Building 580 Taylor Avenue, E-2 Annapolis Maryland 21401-2397 US kevin.coyne@maryland.gov 0800 - 1700 Eastern Time The SAV beds are interpreted on-screen from the orthophoto mosaics using ESRI ArcGIS software. The identification and delineation of SAV beds by photo interpretation utilizes all available information including: knowledge of aquatic grass signatures on film, distribution of SAV in 2023 from aerial satellite imagery, 2023 ground survey information, and aerial site surveys. National Agricultural Imagery Program (NAIP) aerial imagery, as well as WorldView 2 and 3 satellite imagery acquired from Digital Globe through the NGA NextView program, PlanetScope satellite imagery from Planet Labs was used to augment the aerial imagery in portions of the Bay and tributaries where imagery had not been acquired because of highly turbid water, weather, and security restrictions during the acquisition phase. In addition to delineating SAV bed boundaries, an estimate of SAV density within each bed was made by visually comparing each bed to an enlarged crown density scale similar to those developed for estimating crown cover of forest trees from aerial photography (Paine, 1981). Bed density was categorized into one of four classes based on a subjective comparison with the density scale. These were: 1, very sparse (<10% coverage); 2, sparse (10-40%); 3, moderate (40-70%); or 4, dense (70-100%). Either the entire bed or subsections within the bed were assigned a bed density number (1 to 4) corresponding to the above density classes. Some beds were subsectioned to delineate variations of SAV density. Additionally, each distinct SAV bed or bed subsection was assigned an identifying one or two letter designation unique to its map. Coupled with the appropriate SAV quadrangle number and year of photography, these letter designations uniquely identify each SAV bed in the database. 2024 Kevin Coyne Maryland Department of Natural Resources Chief, Geospatial Information and Analysis 410-260-8985 410-260-8835 410-260-8759 Tawes State Office Building 580 Taylor Avenue, E-2 Annapolis Maryland 21401-2397 US kevin.coyne@maryland.gov 0800 - 1700 Eastern Time The bay segments were overlayed on the dataset by VIMS staff, dividing any beds that fell into multiple segments. 2024 Kevin Coyne Maryland Department of Natural Resources Chief, Geospatial Information and Analysis 410-260-8985 410-260-8835 410-260-8759 Tawes State Office Building 580 Taylor Avenue, E-2 Annapolis Maryland 21401-2397 US kevin.coyne@maryland.gov 0800 - 1700 Eastern Time The state boundaries were overlayed on the dataset by VIMS staff, dividing any beds that fell into multiple states. 2025 Kevin Coyne Maryland Department of Natural Resources Chief, Geospatial Information and Analysis 410-260-8985 410-260-8835 410-260-8759 Tawes State Office Building 580 Taylor Avenue, E-2 Annapolis Maryland 21401-2397 US kevin.coyne@maryland.gov 0800 - 1700 Eastern Time The final phase of the process was to prepare the data for distribution by the Maryland Department of Natural Resources. All Submerged Aquatic Vegetation (SAV) data was converted from the Arc/Export format (e00) into an Arc/view shapefile format using Arc/View (Version 3.2). From this point, the Arc shapefile was imported into MicoImages TNT mips (version 6.4) in order to be warped and validated to meet MD-DNR distribution standard (Maryland State Plane 1983, NAD83 with units in meters). All data was then exported back into an Arc Shapefile format for MD-DNR distribution. 2001 Kevin Coyne Maryland Department of Natural Resources Chief, Geospatial Information and Analysis 410-260-8985 410-260-8835 410-260-8759 Tawes State Office Building 580 Taylor Avenue, E-2 Annapolis Maryland 21401-2397 US kevin.coyne@maryland.gov 0800 - 1700 Eastern Time USGS The 2002 data was added and an updated shape file was made. 2002 Kevin Coyne Maryland Department of Natural Resources Chief, Geospatial Information and Analysis 410-260-8985 410-260-8835 410-260-8759 Tawes State Office Building 580 Taylor Avenue, E-2 Annapolis Maryland 21401-2397 US kevin.coyne@maryland.gov 0800 - 1700 Eastern Time The SAV beds were interpreted on-screen from the orthophoto mosaics using ESRI ArcInfo GIS software. The identification and delineation of SAV beds by photo interpretation utilized all available information including: knowledge of aquatic grass signatures on film, distribution of SAV in 2003 from aerial photography, 2003 ground survey information, and aerial site surveys. SAV beds were identified and field checked with the collaboration of Stan Kollar for the head of the Bay region, including Susquehanna Flats; and with Virginia Carter, Nancy Rybicki, Henry Ruhl, and Alfonso Lombana for the Potomac River. Delineation of the large bed on the Havre de Grace map was facilitated by both aerial photography and ground observations. In addition to delineating SAV bed boundaries, an estimate of SAV density within each bed was made by visually comparing each bed to an enlarged crown density scale similar to those developed for estimating crown cover of forest trees from aerial photography. Bed density was categorized into one of four classes based on a subjective comparison with the density scale.

Either the entire bed or subsections within the bed were assigned a bed density number (1 to 4) corresponding to the above density classes. Some beds were subsectioned to delineate variations of SAV density. Additionally, each distinct SAV bed or bed subsection was assigned an identifying one or two letter designation unique to its map. Subsections were further identified as contiguous beds by addition of one or two letters unique to that sequence. Contiguous bed identifications aided tracking and analysis of single natural bed units subsectioned due to variations of SAV density. Coupled with the appropriate SAV map number and year of photography, these letter designations uniquely identify each SAV bed in the database. After all quadrangles were digitized, the resulting digital data was combined to form a single data set for the entire Bay. The quadrangle borders were then checked and edited (edge matched) to ensure that the SAV polygons were consistent. Inconsistencies were resolved by checking the mylar maps and re-interpreting the photography if necessary. The bay segments were overlayed on the dataset by VIMS staff, dividing any beds that fell into multiple segments. The state boundaries were overlayed on the dataset by VIMS staff, dividing any beds that fell into multiple states. The final phase of the process was to prepare the data for distribution by the Maryland Department of Natural Resources. All Submerged Aquatic Vegetation (SAV) data was converted from the Arc/Export format (e00) into a coverage in Arc Catalog (Version 9.1) and then exported to an Arc/view shapefile format using ArcMap (Version 9.1). From this point, the Arc shapefile projection UTM was converted to meet MD-DNR distribution standard (Maryland State Plane 1983, NAD83 with units in meters) using the Arc Toolbox (Version 9.1). 2003 Kevin Coyne Maryland Department of Natural Resources Chief, Geospatial Information and Analysis 410-260-8985 410-260-8835 410-260-8759 Tawes State Office Building 580 Taylor Avenue, E-2 Annapolis Maryland 21401-2397 US kevin.coyne@maryland.gov 0800 - 1700 Eastern Time The SAV beds were interpreted on-screen from the orthophoto mosaics using ESRI ArcInfo GIS software.
