Frequently anticipated questions:

What does this data set describe?

Title: Remote Sensing Coastal Change Simple Data Distribution Service
The Remote Sensing Coastal Change Simple Data Service provides timely and long-term access to emergency, provisional, and approved photogrammetric imagery, derivatives, and ancillary data through a web service via HyperText Transfer Protocol to a folder/file structure organized by data collection platform and survey (collection effort) with metadata sufficient to facilitate both human and machine access. Data are acquired, processed, and published using standardized workflows. Each data type added to the service has a peer-reviewed metadata and data review of sample data generated with standardized methods to ensure compliance with U.S. Geological Survey (USGS) Fundamental Science Practices (FSP).

Why was the data set created?

This data service supports coastal hazards research, management, and emergency response by providing timely access to photogrammetric imagery and derivatives collected by a variety of data collection platforms (DCPs), processed using documented photogrammetry and machine-learning techniques, and reviewed for quality using standardized procedures. Products for a given DCP include, at a minimum, digital images and/or image products intended for photogrammetric workflows, and may include derivatives and ancillary data, including, but not limited to, processed camera position and pose, camera and lens models, geospatial raster and vector data (for example orthoimagery/digital elevation models/triangulated irregular networks), point clouds, segmented images, and image labels in scalar, vector, and raster formats.
Imagery, derivatives, and ancillary data released through this data service are processed with documented standardized methods, reviewed for quality and accuracy in accordance with USGS Fundamental Science Practices (FSP), and accessed in a folder structure organized by platform, survey, and product, with associated metadata describing data structure and contents. Metadata and data structures are designed to provide access to the data at the most granular level possible to facilitate efficient manual or automated access to only the data needed or queried by users.

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

  1. How well have the observations been checked?
    No formal attribute accuracy tests were conducted for this data service. See metadata for individual data collection platforms (DCPs) and associated data products for accuracy information on data products provided by this service.
  2. How accurate are the geographic locations?
    Horizontal accuracy is dependent on product type. See DCP and specific data product metadata positional accuracy reports for additional details.
  3. How accurate are the heights or depths?
    Vertical accuracy is dependent on product type. See DCP and specific data product metadata positional accuracy reports for additional details.
  4. Where are the gaps in the data? What is missing?
    Data are considered complete for the information presented, as described in the abstract. Additional imagery will be added as datasets become available. Users are advised to carefully read the rest of this metadata record and metadata records for relevant DCPs and associated data retrieved from this data service for additional details.
  5. How consistent are the relationships among the observations, including topology?
    No formal logical consistency tests were conducted on this data service.

How can someone get a copy of the data set?
