Title: Development: Development delineation: Parker River, MA, 2014
Abstract:
Understanding how sea-level rise will affect coastal landforms and the species and habitats they support is critical for crafting approaches that balance the needs of humans and native species. Given this increasing need to forecast sea-level rise effects on barrier islands in the near and long terms, we are developing Bayesian networks to evaluate and to forecast the cascading effects of sea-level rise on shoreline change, barrier island state, and piping plover habitat availability. We use publicly available data products, such as lidar, orthophotography, and geomorphic feature sets derived from those, to extract metrics of barrier island characteristics at consistent sampling distances. The metrics are then incorporated into predictive models and the training data used to parameterize those models. This data release contains the extracted metrics of barrier island geomorphology and spatial data layers of habitat characteristics that are input to Bayesian networks for piping plover habitat availability and barrier island geomorphology. These datasets and models are being developed for sites along the northeastern coast of the United States. This work is one component of a larger research and management program that seeks to understand and sustain the ecological value, ecosystem services, and habitat suitability of beaches in the face of storm impacts, climate change, and sea-level rise.

Why was the data set created?

The vector layer delineates areas of human development. Polygons were hand-digitized from 1-m aerial imagery captured in 2014 and outline areas of general human development (for example, buildings, residential development, paved roads) as well as coastal armoring (for example, jetties and groins). The data were used in vector format during a supervised land cover classification and converted to raster format to be merged with other land cover sub-classifications, producing the supervised classification raster layer (PR14_SupClass.tif in larger work).
This dataset is part of a series of spatial datasets used to describe characteristics of barrier islands found along the North American Atlantic coast in order to identify habitat for the federally protected piping plover (Charadrius melodus). Information contained in these spatial datasets was used within a Bayesian network to model the probability that a specific set of landscape characteristics would be associated with piping plover habitat (Zeigler and others, 2019).

How was the data set created?

  1. From what previous works were the data drawn?
    Orthoimage (source 1 of 1)

    Imagery is available by request. Request NAIP14 1m imagery for Plum Island and Crane Island, Essex County, MA from apfo.sales@slc.usda.gov. Further instructions at the first link.
    Type_of_Source_Media: digital data
    Source_Contribution:
    Visual imagery used for digitizing shorefront development. Source data were distributed at 1 m pixel resolution, in horizontal datum NAD83. Downloaded on 4/5/2016. Data were projected to UTM Zone 19N (EPSG:26919) using the ‘Project Raster’ tool in ArcToolbox (version 10.4.1).
  2. How were the data generated, processed, and modified?
    Date: 2017 (process 1 of 2)
    In Edit sessions of ArcGIS version 10.4.1, Sara L. Zeigler manually outlined areas that were anthropogenic development in the orthoimage. The features considered development included buildings and other man-made structures, paved roads, groins, jetties, and seawalls. Undeveloped areas that were completely surrounded by development were included in development polygons, based on the rationale that these areas could not be accessed by a piping plover chick.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
  2. How accurate are the geographic locations?
    The horizontal accuracy of the vector layer inherits the accuracy of the orthoimagery from which it was derived (see source contribution information).
    This dataset was derived through manual digitization based on visual interpretation of aerial imagery. Some error is intrinsic in the manual process. We estimate the accuracy of this development raster to be within 5 m horizontally. No formal accuracy assessments have been conducted.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    This dataset contains all human development within a custom boundary, to the best of our knowledge based on visual inspection of orthoimagery. This dataset may not include the entire spatial extent of the original source dataset as it was published in original form. However, the custom boundary spans the entire coverage of the site relevant to the broader research program (see Zeigler and others, 2019 for more details). This dataset is therefore considered complete for the information presented as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details.
  5. How consistent are the relationships among the observations, including topology?
    This vector layer depicts hand-digitized areas of human development. It was produced manually based on visual inspection of orthoimagery. The polygons may include undeveloped areas that are completely surrounded by development because these areas could not be accessed by a piping plover chick. The data were reviewed using standard USGS review procedures. No checks for topological consistency were performed on these data.
