Mission

  • Linking People, Information, and Technology in the Coastal Zone

    Customers and Partners = State and Local Coastal Managers

  • Regulatory agencies

  • GIS and remote sensing staff

  • Planners

  • Scientists

  • Emergency preparedness

    Primary Themes

  • Coastal Hazards

  • Coastal Habitat

  • Integrated Ocean Observing Systems

    Annual Operating Plan

  • Approximately 125 projects per year

  • 90% have local partner who sets requirements

    Agency Funding

  • CSC funded through government appropriations


Primary geospatial products and services
Primary Geospatial Products and Services Geospatial Data Standards and Access

Data Development (private contract and in-house)

  • Coastal topography (IfSar and Lidar)

  • Coastal landcover and change (Landsat-based)

  • Coastal imagery (high res satellite, digital cameras)

  • Benthic and Submerged Aquatic Vegetation

  • Open licensing and data distribution

    Application Development (ESRI and OpenSource)

  • Maintain 3-tier development architecture and testing lab

  • Desktop and Internet; DSS and data distribution

    Geospatial Standards

  • Active in multiple standards bodies (OGC, ISO, FGDC, FEA)

  • Dual role – develop and promote standards

    Training

  • Develop and teach full range of GIS (intro and intermediate), Remote Sensing, GPS, and metadata courses

    Grants

  • Competitive grant programs to fund state-level projects (CSC support includes both $$$ and staff support [data, coding])


CSC Web Mapping Template Geospatial Data Standards and Access

  • CSC maintains approximately 50 IMS sites for a wide variety of purposes

    • Hurricane Tracks, Lidar Data Distribution, River Flood Modeling, Coastal Landcover Change, Ocean Planning and Boundaries

  • Decision made three years ago to move to a standard template for almost all IMS sites (except when requirements dictate otherwise)

  • Template implementation uses ESRI ArcIMS HTML viewer

    • Emphasis on reusable and sharable code, new functionality is added regularly

    • Reduces development time and costs + eases migration with new code releases

    • Enhances user experience – learn CSC tools once, use on many sites

  • Newest version in development provides the same look & feel and functionality but built on MapServer code base

    • OpenSource solution

    • MapServer is not as feature rich or scalable as ArcIMS

Fgdc and nsdi
FGDC and NSDI Geospatial Data Standards and Access

  • Federal Geographic Data Committee (FGDC) is a 19-member interagency committee, organized in 1990 under OMB Circular A-16, that promotes the coordinated use, sharing, and dissemination of geospatial data on a national basis

    • FGDC funded through Dept of Interior appropriations and in-kind support from others

  • In 1994, Presidential Executive Order 12906 called for the nation’s development of the National Spatial Data Infrastructure (NSDI) (US component of Global NSDI)

    • Current and accurate geospatial data will be readily available to contribute locally, nationally, and globally to economic growth, environmental quality and stability, and social progress

  • NSDI Components

    • Clearinghouse - need to find and access data (now GOS)

    • Metadata - need to know characteristics of data

    • Framework - need for common sets of data

    • Standards/Technology - need to transfer/integrate data

    • Partnerships - need to leverage resources

  • NSDI composed of 33 data themes of national significance

    • Seven Framework Themes – e.g. geodetic control; transportation; hydrography; topography

    • Marine and Coastal included – e.g. maritime baseline; marine boundaries; shoreline; bathymetry

Geospatial one stop gos
Geospatial One-Stop (GOS) Geospatial Data Standards and Access

What is it?

  • One of 24 E-GOV projects initiated to enhance federal government service delivery (only geospatial project)

  • GOS Goal – provide single point of access for all federal (and some state and private) geospatial data sets

  • All FGDC member agencies required to participate and fund project (cash and in-kind resources) – operating budget of ~$3.0M + agency in-kind support

  • Managed by one federal agency (Department of Interior) but overseen by 8-member Board of Directors (4 Federal representatives and 4 non-Federal)

  • Site organized around Communities (Data and Special Topics)

    Technical Implementation

  • Site developed and managed by ESRI with Google (enhanced searching) and IBM (portlets)

  • System driven by FGDC metadata records (125K)

  • Components include search interface, IMS tool, communities, geospatial marketplace, metadata development tools

Perspectives on gos
Perspectives on GOS Geospatial Data Standards and Access

Positives

  • Participation by all federal agencies (some more than others)

  • Stable funding and support (agencies are taxed and required to provide in-kind support)

  • Dedicated GOS project office and staff

  • Strong private sector involvement (ESRI, Google, IBM)

  • Diverse Board of Directors Structure

    Negatives

  • Searching results need to be refined to prioritize ‘best’ datasets

    • Too much information given current searching algorithms

  • Automated metadata harvesting never realized (manual process)

  • Need to provide site usage (amount and profile) to partner agencies

  • No data delivered via site – links to data provider

  • GOS Marketplace has not met initial goals

Nos data explorer why build it
NOS Data Explorer - Why Build It? Geospatial Data Standards and Access

  • NOAA\National Ocean Service creates many of the key US coastal datasets

    • Geodetic control

    • Nautical Charts - ENCs

    • Shoreline

    • Bathymetry

    • Marine boundaries

    • Environmental Sensitivity Index

    • Coastal Hazards

    • Tides and Water Levels

  • Prior to Data Explorer, users must navigate multiple sites to find data

  • Variety of data delivery approaches

  • No single interface for previewing composite data at one location

  • Complexity of discovery and delivery


Data explorer basics and roles
Data Explorer Basics and Roles Geospatial Data Standards and Access

Data Explorer Basics

  • Goal - centralized searching and delivery of datasets and metadata from multiple NOS program offices from one Internet site

  • Does not replace existing program office data access sites or require any substantial additional work from them (do no harm + add no burden)

  • Connectivity provided through open standards (OpenGIS, XML, TCP/IP, HTTP)

  • Hosts 75 unique data layers and 350+ unique metadata records

  • Governance – core developer team and program office representatives

  • Funded via support of key program offices doing DE development (three offices)

    What does the Data Explorer core site hold?

  • Metadata records from program offices

  • Inventory files or “footprints” for each dataset

  • Inventory of “services” – how to connect to each dataset

    What do the program offices maintain?

  • Keep metadata and footprint inventory up to date

  • Store all data and provide access via database connection, ArcIMS, OGC service, or FTP files

Perspectives on data explorer
Perspectives on Data Explorer Geospatial Data Standards and Access

Positives

  • Good participation across all program offices

  • True access to distributed datasets across multiple offices

  • Code sharing and building networks among software developers

  • Model for NOAA-wide implementation

    Negatives
