Geospatial Data + Documents

Where to Start

Types of Spatial Coastal Data

• Project Specific Spatial Data

• Engineering

• Environmental

• Monitoring Surveys

• Topo and Bathymetric

• Natural Resources

• Sediment and Water

• Regulatory (Federal, State, County)

• Base Layers (Federal, State, County)

Consolidation & Organization

• Data type and format

• What programs use a specific dataset

• Does it need additional external information to complement the dataset

• What type of information does the County need

• Best way to consolidate in GIS

Hydrographic Surveys

• County Shoreline

• St Lucie Inlet and adjacent areas

• Navigation & Sediment Basin

• Beach restoration surveys

• Pre and Post Construction

• 1 to 3 Year post monitoring

• Borrow areas

• Waterway projects

• Artificial reefs

County needs to access the

original data, what areas

were surveyed and when,

compare surveys —

volume changes and where

— erosion, accretion,

extract cross sections, and

depth for different projects

Hydrographic Surveys

GIS

Geodatabases

Original XYZ XYZ

LIDAR files

• Beach Lighting Surveys are required monitoring for beach restoration permits

Sea turtles when they hatch “look for” the moon to find the ocean

• Beach property lighting if

seen from the beach may cause the hatchlings to get disoriented and go towards the lights instead of the ocean

• Survey identify light issues that need to be corrected by the property owners.

Beach Lighting Surveys

County needs to know

what and where is the

issue, if it is recurrent, if it

was fixed, and there are

any disorientation reported

in the problem area

How it is used

GIS is now Part of the Coastal Engineering Department Workflows

• Project Information Consolidation and Organization & Lookup

• Asset Management (i.e. Channel Markers)

• Project Management & New Project Planning

• Data Analysis

• Prepare Grant and Permit Applications

• Public and Stakeholders Sharing of Information

• Visual Aids for Meetings

• Brochures
