Description:

Abstract:

Elevation distribution in the Assateague Island National Seashore (ASIS) salt marsh complex and Chincoteague Bay is given in terms of mean elevation of conceptual marsh units defined by Defne and Ganju (2018). The elevation data is based on the 1-meter resolution Coastal National Elevation Database (CoNED). Through scientific efforts initiated with the Hurricane Sandy Science Plan, the U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands, including the Assateague Island National Seashore and Chincoteague Bay salt marshes, with the intent of providing Federal, State, and local managers with tools to estimate the vulnerability and ecosystem service potential of these wetlands. For this purpose, the response and resilience of coastal wetlands to physical factors need to be assessed in terms of the ensuing change to their vulnerability and ecosystem services.

Purpose:

The purpose of this shapefile is to calculate mean elevation for each marsh unit and its vegetated component. Analysis of marsh elevation is part of a comprehensive assessment to identify the factors and their weights in determining the vulnerability and resiliency of salt marshes.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Marsh units, water and land boundary inherit their accuracy from accuracy of the source data, ASIS marsh units, and vertical accuracy of the 1-meter resolution U.S. Geological Survey Coastal National Elevation Database (USGS CoNED) data with processing date of 2016.

Logical_Consistency_Report:

Positive elevation indicates above sea level. Marsh units with extremely low elevation (smaller than 0.2 percentile value), with extremely high elevation (larger than 99.8 percentile value) or with areas less than 900 square meters were flagged.

Completeness_Report:

The results are specific to the marsh polygons definition within the boundaries of the ASIS and Chincoteague Bay salt marsh complex. A detailed on-the-ground analysis of a single site may result in a different interpretation of the wetland and marsh unit boundaries. Coverage near the domain boundaries in Wallops Bay and Wallops Island is not complete and not suggested for use in analyses (specifically marsh units with FID_CMU=3, 1659, 1666, 1672 and 1728).

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Horizontal accuracy is inherited from the source dataset that delineates the marsh units, and can be considered to be +/-6 meters.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Because the elevation values are averaged over delineated polygons, vertical accuracy depends on both the horizontal accuracy of NWI dataset and the vertical accuracy of source elevation data, CoNED. CoNED vertical elevation accuracy was 0.2 meters.

Used the features in [CMU_ASISp.shp] to calculate the mean elevation for each marsh unit. Projection was WGS 1984 Web Mercator Auxiliary Sphere.

Process_Step:

Process_Description:

This process step and all subsequent process steps were performed by the same person, Zafer Defne, in ArcMap (ver. 10.5.1) using tools from ArcToolbox, unless otherwise stated. For complex operations, names of specific tools used are given in CAPITAL letters (any critical parameters used are given in parentheses, separated by a semicolon, immediately after the tool name). The input and output file names are provided in [square brackets] when necessary. Units for length and area calculations are meters (m) and square meters (m2) unless otherwise stated.
a) Set the data frame coordinate system and projection to NAD 1983 UTM Zone 18N. Prepare elevation dataset to be clipped to the boundaries polygon. MOSAIC TO NEW RASTER(Pixel type= 32 bit float; Mosaic operator=Mean; Cellsize=1 m) all of the CoNED raster to a new raster dataset with 1 m resolution [elev_mosaic.tif].
b) Calculate values for each marsh unit. DISSOLVE(Input features=[CMU_ASISp]; Dissolve field=FID_CMU; Statistics field=ATOT_M2 and FLG with Statistics type= First) to dissolve the vegetated and unvegetated classes in each marsh unit. FLG flags anomalous marsh units based on absence of vegetation, elevation and surface area, and is set to (-1) no vegetated area; (-10) marsh unit elevation higher than the 99.8 percentile; (-100) marsh unit elevation less than 0.2 percentile; (-1000) marsh unit surface area less than 900 m2; and (0) no flag. Combination of negative values indicate combination of flags. For example, -1001 indicates no vegetated area and area less than 900 m2. PROJECT(Input coordinate system=WGS 1984 Web Mercator Auxiliary Sphere; Output coordinate system=NAD 1983 UTM Zone 18N; Geographic transformation=WGS 1984 (ITRF00) to NAD 1983) the feature dataset to obtain dissolved marsh units [mu_diss.shp].
c) Clip the raster with the polygon features by using EXTRACT BY MASK to obtain [elev_idw_mu.tif].
d) ZONAL STATISTICS AS TABLE(Feature Zone Data=[mu_diss.shp]; zone field=FID_CMU; Value Raster=[elev_idw_mu.tif]; Output Table=mu; Statistics type=MEAN)
e) ADD JOIN(Layer name=[mu_diss.shp]; Input join field=FID_CMU; Join Table=mu; Output join field=FID_CMU) to marsh units layer based on the "FID_CMU" field
f) Export dataset as a shapefile [mu_elev.shp] and keep the 'mu_MEAN" and "mu_ATOT_M2" fields from the join operation.
g) Calculate elevation of the vegetated areas only. SELECT BY ATTRIBUTES FROM [CMU_ASISp] where "CLASS"= 'vegetated'. SELECT BY ATTRIBUTES FROM [CMU_ASISp] where "CLASS"= 'vegetated'. Follow steps (c) to (f) using the selected features to export [veg_elev.shp].
h) JOIN FIELD(Input table=[mu_elev.shp]; Input join field=mu_FID_CMU; Join table=[veg_elev.shp]; Output join field=vg_FID_CMU; Join fields=vg_AVEG_M2,vg_ATOT_M2,vg_MEAN). Change the field names to VG_ELEV and MU_ELEV respectively for the fields with the mean elevation for the vegetated area only and mean elevation for the entire marsh unit. Name AVEG_M2 and ATOT_M2 for vegetated and total area, respectively, and export to a new shapefile. [mu_elev_ASIS.shp].
i) SELECT BY ATTRIBUTES FROM [CMU_ASISp] where "CLASS"= 'vegetated', and join field "APGN_M2" from CMU_ASISp.shp on the feature dataset [mu_elev_ASIS.shp].
j) Rearrange field names and change the projection for better performance of web services with online base maps. PROJECT(Input coordinate system=NAD 1983 UTM Zone 18N; Output coordinate system=WGS 1984 Web Mercator Auxiliary Sphere; Geographic transformation=WGS 1984 (ITRF00) to NAD 1983) the feature dataset to obtain the final conceptual marsh units [mu_elev_ASISp.shp].

Overview_Description:

Entity_and_Attribute_Overview:

In this dataset, mean elevation for each conceptual salt marsh unit in the ASIS and Chincoteague Bay salt marsh complex has been calculated based on the 1-meter resolution raster source dataset. Decimal values in the attribute table are a result of double precision calculations while significant digits are considered in defining the attribute measurement resolutions. Therefore, the smallest unit increment for area values and elevation is assumed to be 1 meter and 0.01, respectively.
