MGS contracted the services of EarthData International, Inc. (EDI), currently of Frederick, Md., to extract shorelines from an existing wetlands delineation, which was based on photo interpretation of 3.75-minute digital orthophoto quarter quads (DOQQs). In areas where a wetlands coverage was not yet available, EDI interpreted shorelines directly from the orthophotography. DOQQ registration (Maryland State Plane Coordinate System, NAD 83, meters) was transferred automatically to the shoreline vectors. Following shoreline extraction or interpretation, EDI assigned attributes to the vectors based on shoreline type: beach, vegetated, structure, or water’s edge. All four categories are linear features, except “beach,” which, if sufficiently wide, can be both linear and polygonal. Shorelines were merged into 7.5-minute quadrangles, provided that the aerial photography on which the DOQQs were based was flown in the same year. MGS used the shorelines to create a series of Shoreline Changes maps. In doing so, MGS erased the landward edge of beach polygons, leaving the seaward edge intact as a linear feature. The Geographic Information Services Division of the Maryland Department of Natural Resources (DNR) merged the shorelines for all of the 7.5-minute quadrangles into a single, statewide coverage. MGS, working collaboratively with Towson University’s Center for Geographic Sciences (CGIS), subsequently used the recent shorelines, along with historical ones, as input into a U.S. Geological Survey (USGS) program, the Digital Shoreline Analysis System (DSAS) (Danforth and Thieler, 1992; Thieler and others, 2001). DSAS determines linear rates of shoreline change (erosion or accretion) along closely spaced, shore-normal transects. Based on DSAS output, the collaborators assigned the following erosion rate categories as attributes to the recent shoreline, clipped by county from the statewide coverage: >High erosion rate (more than 8 ft/yr) >Moderate erosion rate (4-8 ft/yr) >Low erosion rate (2-4 ft/yr) >Slight erosion rate (0-2 ft/yr) >No change >Accretion >Protected >Unknown >No Data The data set contains recent shoreline vectors for sixteen coastal counties and Baltimore City (see Appendix 1), assigned both shoreline type and erosion rate attributes. The vectors represent shoreline positions between the years 1988 and 1995. The metadata was originally written to document the recent shoreline vectors, interpreted, directly or indirectly, from DOQQs and merged by 7.5-minute quadrangle. It was amended to include information about the erosion rate attributes later assigned to the county shorelines. Purpose: This data set complements a set of historical digital shorelines for the Maryland reaches of the Chesapeake Bay, the coastal bays, and the Atlantic coast. That data set spans the period 1841-1977. The two data sets are being used to update a series of Shoreline Changes maps and to determine coastal land loss during the last half of the 20th century. Other State agencies will be able to use this data to analyze and update land loss information, analyze historical erosion trends, and assess the extent and magnitude of shore erosion on a regional geographic basis. In particular, the availability of up-to-date shoreline change data will support the design and implementation of shore protection projects and the development of a comprehensive shore erosion control plan. Supplemental_Information: This document serves as metadata for recent (ca. 1990) shoreline vector files, assigned erosion rate attributes, for Baltimore City and 16 coastal counties in Maryland.

CGIS checked the accuracy of the erosion rate classification by displaying both the shore-normal transects and the shoreline, color-coded, respectively, by erosion rate (ft/yr) and erosion rate category (high, moderate, low, etc.). If the color of the transects matched the color of the associated shoreline segment, CGIS accepted the erosion rate classification. Otherwise, CGIS changed the classification. Logical_Consistency_Report: EDI checked logical consistency through a series of quality assurance/quality control (QA/QC) procedures, reported in Section 2.5.2 Process Step (interpretation/extraction of shorelines). Completeness_Report: The area covered includes 125 7.5-minute quadrangles lying at least partially within Baltimore City or one of the 16 coastal counties of Maryland. Shorelines located in out-of-state areas, such as the Virginia side of the Potomac River, were excluded. In digitizing historical shorelines from hard copy maps, MGS had adopted an operational definition of the headward extent of a stream - the point at which the stream was represented on the map by a single line rather than a double line delineating opposite stream banks. That point, dependent as it is on the scale of the map, does not necessarily represent the head of tide. A similar criterion was used in extracting the 1990 shoreline. To the extent that the contractor could fit a double line on photography displayed at a scale of 1:24,000, the shoreline was extracted. Reaches upstream of that point were excluded. Again, the headward extent of a digitized stream does not necessarily correspond with head of tide. Shorelines in the 1990 data set bounded several different wetlands classifications (Cowardin et al., 1979): >1. E 1 UB L (Estuarine -- Subtidal -- Unconsolidated bottom -- Subtidal) >2. E 2 US M (Estuarine -- Intertidal -- Unconsolidated shore -- Irregularly exposed) >3. E 2 US N (Estuarine -- Intertidal -- Unconsolidated shore -- Regularly flooded) >4. E 2 US P (Estuarine -- Intertidal -- Unconsolidated shore -- Irregularly flooded) >5. M 2 US M (Marine -- Intertidal -- Unconsolidated shore -- Irregularly exposed) >6. M 2 US N (Marine -- Intertidal -- Unconsolidated shore -- Regularly flooded) >7. R 1 UB V (Riverine -- Tidal -- Unconsolidated bottom -- Permanent tidal (tidally influenced, freshwater system) >8. R 2 UB 8 -- (Riverine -- Lower perennial -- Unconsolidated bottom -- Eusaline) In addition to designating UB L and UB V as water, M 2 or E 2 US (Unconsolidated shore) M (Irregularly flooded) or N (Regularly flooded) classifications were considered water, given that those areas were more likely to be under water than above. E 2 US P (Irregularly flooded) was considered upland, given that those areas were more likely to be above water than under. In assigning rate-of-change attributes, MGS and CGIS devised and applied a number of rules, which are summarized below: >Classify shoreline segments of the shoreline type "structure" as "protected." >When adding nodes to distinguish between shoreline reaches with different rates of change, insert nodes only after the occurrence of a series of four or more similarly colored transects. For example, along an extensive reach that has experienced moderate rates of erosion, interrupted by two adjacent transects characterized by high erosion rates, classify the entire stretch of shoreline as "moderate." If, instead of two high-rate transects, six high-rate transects occur in a row, insert nodes on either side of the six transects, and classify that shoreline reach as "high." >If shorelines are so complex that it is difficult to distinguish between the two shoreline years or to see that they are properly positioned, assign the erosion rate category "Unknown." This problem is particularly common in marshy areas and/or along minor tributaries of dubious positional accuracy. A common manifestation of the latter is that one bank of the tributary is erosional along its entire length, while the opposite bank is accretional. >For reaches lacking transects, estimate rates based on the relative positions of the two shorelines. This situation is common along points of land projecting into the water. >Classify stretches represented by a single shoreline as "No Data." >If the two shorelines interweave over an extended reach, with little lateral displacement, classify the stretch as "No Change." Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The DOQQs meet National Map Accuracy Standards at the production scale of 1:12,000, using the American Society for Photogrammetry and Remote Sensing (ASPRS) method. The contractor who produced the DOQQs provided a detailed aerotriangulation report for each production area. The production of accurately georeferenced DOQQs depends on sufficient ground control. In open water, ground control is necessarily lacking, because land areas, if they exist at all, are small and/or inaccessible. Two quarter quads in the data set, Deal Island NW and Barren Island NE, contain so much open water that they are not properly tied to the adjoining tiles, Nanticoke SW and Honga NW, respectively. Consequently, the corresponding linework (shoreline) is not properly georeferenced. The shorelines derived from those two DOQQs are included in the data set solely for the associated attribute (shoreline type) information. Their positions are inaccurate.

Negative rates indicate shoreline retreat, and positive rates, shoreline advance. Process_Step: Process_Description: Under contract to MGS, EDI extracted or interpreted the modern (1988-1995) shoreline directly or indirectly from digital orthophotography. For all but 35 of the quarter quads, EDI extracted the shoreline from existing wetlands vectors, previously delineated for the Maryland Department of Natural Resources (DNR) over 1:1,000-scale DOQQs. The DOQQs, in turn, were derived from 1:40,000-scale color infrared (CIR) film. For the remaining 35 quarter quads, the shoreline was interpreted directly from the DOQQs. For shoreline vectors extracted from the existing wetlands coverage, EDI stripped wetlands vectors of their linear attributes (line classes). All shorelines and the DOQQ tile boundary were displayed over the DOQQ (raster) from which they were originally interpreted and reassigned attributes. Shoreline segments were classified using the following four categories: beach, structure, vegetated, and water’s edge. All four categories are linear features, except for "beach," which can be both linear and polygonal. The DOQQ tile boundary was arbitrarily assigned one of the four categories so that it could be extracted with the shoreline vectors. Shoreline vectors were extracted from the original vector set by line class, using only the four shoreline categories. The extracted vectors were then displayed to detect shoreline breaks or other inconsistencies. Errors were corrected, and shoreline vectors were re-extracted. After extraction, vector sets were cleaned by deleting any extraneous lines (non-shoreline vectors) that had mistakenly been assigned one of the four categories before extraction. Beach polygons were attributed at this time, and the DOQQ tile boundary was assigned to a fifth category -unclassified. The final quality control check consisted of two steps. First, each tile (quarter quad) was displayed individually to check for unclassified shoreline vectors. Second, if the photography on which the DOQQs were based was flown in the same year, vectors from adjacent tiles were merged into a single, 7.5-minute quadrangle vector set. Otherwise, multi-year shorelines for the same quadrangle were stored as separate objects within the TNTmips project (.rvc) file. Merged vector sets were displayed to check for class consistency (proper edge matching) between adjacent tiles. Any necessary corrections were made before saving the final vector sets. Shorelines derived directly from DOQQs were interpreted according to the procedure outlined in the wetlands inventory metadata. The DOQQs were already georeferenced to the Maryland State Plane Coordinate System (North American Datum of 1983, meters). Georeferencing was transferred automatically upon delineating either wetlands or shorelines. MGS subsequently converted beach polygons to line segments by removing the landward edge of the polygon.

DSAS constructs a 50-meter buffer around a series of digital shorelines. From the landward side of the buffer, or baseline, DSAS casts transects at 20-meter intervals, perpendicular to the baseline. For each transect, DSAS computes rates of change based on all shorelines intersected by the transect, as well as rates for each successive pair of shorelines. If, for example, a transect crosses shorelines from 1850, 1900, 1950, and 1990, DSAS output includes rates for the following “eras”: 1850-1900, 1900-1950, and 1950-1990. In assigning erosion rate attributes to the ca. 1990 shoreline, MGS and CGIS used rates based on the most recent era, that is, the one ending in 1988-1995. Usually, that era spanned approximately 50 years, from the 1940s to the 1990s. In some cases, however, the era was considerably shorter (e.g., 1975-1990) or longer (e.g., 1850-1990). CGIS assigned erosion rate attributes to the recent shoreline by: >1. Color-coding transects according to previously established rate-of-change categories: >High - High erosion rate (more than 8 ft/yr) >Moderate - Moderate erosion rate (4-8 ft/yr) >Low - Low erosion rate (2-4 ft/yr) >Slight - Slight erosion rate (0-2 ft/yr) >Accretion >2. Visually grouping similarly colored transects, >3. Inserting nodes between transects that differed in color, and >4. Assigning the appropriate classification code to the shoreline reach. The rules that CGIS followed in the process are described in Completeness Report.
