a tour of new spatial data products

SALCC Introduction

In this three part webinar series we will explore newly available spatial

products that predict future conditions

• 6/21/12: Urban Growth• 8/16/12: Sea level rise • 10/18/12: Land cover

SALCC Introduction

The SALCC is a forum in which the private, state and federal conservation community…

develops a shared vision of landscape sustainability

cooperates in its implementation; and

collaborates in its refinement

Mission:Create a shared blueprint for

landscape conservation actions that sustain natural and cultural

resources

SALCC Introduction

What is the Blueprint?An interactive, living plan that

describes the places and actions needed to meet the SALCC’s conservation priorities in the

face of future change

Conservation Priority = Measurable indicator of success

SALCC Introduction

*calculated from the NOAA medium resolution digital vector shoreline

About the SALCC area

• Portions of 6 States

• 89 million acres

• 92% private land

• 18,700 miles of coastline*

SALCC Introduction

Why is the SALCC interested in these spatial data?

To achieve our mission, we need to be able to understand and model the forces that drive

change on the landscape

The spatial data products we are highlighting cover the entire

SALCC area and as far as your staff knows, these are currently the best data available for our

region

Do you know of other comparable data that cover our

entire region?

What is SLAMM?

Sea Level Affecting Marshes Model

Developed by 1Park et al. for EPA in the 1980’s

Simulates nearshore processes such as accretion, erosion, marsh migration due to sea level rise

NOT simply an inundation “bathtub” model

Interface for SLAMM v. 5 developed by 2Clough – Warren Pinnacle Consulting

SLAMM for Conservation: DSL

Designing Sustainable Landscapes (DSL) Project

Coordinated research project between• USGS Cooperative Fish & Wildlife Research Units of NC

and AL• Atlantic Coast Joint Venture• Biodiversity and Spatial Information Center

In part: Predict landscape-level change effects on avian habitats in SE due to urban growth, succession, climate change, and conservation programs

2008 – 2010

South Atlantic Migratory Bird Initiative (SAMBI) region: Southeastern Coastal Plain from southern VA to northern FL

SLAMM Vegetation dynamics

SLAMM for Conservation: DSL


SLAMM Application in the SAMBI


http://www.basic.ncsu.edu/dsl/slr.html

Requires 4 spatial inputs:

National Wetlands Inventory (NWI) data cross-walked to 23 (22) SLAMM categories

• Dikes / Impoundments

Digital Elevation Model – National Elevation Dataset (NED) used at 30m resolution augmented with LiDAR data for NC

Slope derived from DEM

Impervious surface from National Land Cover Dataset



“Site” file information:

Tidal datum data

Sea level rise trend data

from NOAA NOS/CO-OPs stations

downloadable from NOAA website:

http://co-ops.nos.noaa.gov/station_retrieve.shtml?type=Datums



SLAMM v5.0 Interface6 Sea Level Rise scenarios

Option to “protect developed”

GIS outputs

Adjustable simulation time steps



DSL in the SAMBI:

Ran in 10 year increments from 2000 to year 2100

Ran with emission scenarios (SLR)

• A1B, A2, A1FI, and B2

Protect Developed

Ran separately for each of 39 8-digit Hydrologic Unit Codes (HUCs)

Outputs available for download from project website

SLAMM & Vegetation Dynamics: Scale


DSL in the SAMBI:

Output rasters 30 meters

TELSA modeling polygons MMU ~10 hectares

SLAMM processed by 8-digit HUC ≈ 1800km2

Scale not appropriate for:• Parcel level threat assessments• Finer scale land cover type transitions• Anything other than regional scale analyses or as a first

tier filter for finer scale studies

SLAMM Issues


Accretion rates – doesn’t allow for vegetative decay after inundation – no build up of new marsh, only inundation of old marsh

Offshore direction forces transitions

Cross-walking/clumping NWI to 23 SLAMM classes means lose of information

Elevation data – NED has numerous problems – potential fix is LiDAR
