Alternative Text Description for 2 ft. Contours (Woolpert)

TABLE OF CONTENTS

MAP OVERVIEW

This map displays 2-foot elevation contours for coastal areas of Florida. The contours represent lines of equal elevation at 2-foot vertical intervals, derived from LiDAR data collected for the Florida Division of Emergency Management. The map shows the detailed topographic relief of Florida's coastal zones, with contour lines indicating changes in ground elevation across the landscape.

GEOGRAPHIC CONTEXT

The map covers major coastal regions of Florida, including both the Gulf of America coast and Atlantic coast. Major urban areas visible include Tampa, St. Petersburg, Sarasota, Cape Coral, and areas near Orlando on the western side of the state. On the eastern coast, coverage includes areas near Melbourne and Palm Bay. The map extends inland from the coastline to varying distances, with some coverage reaching Lake Okeechobee in south-central Florida. The contour data appears in distinct brown/tan colored zones representing specific geographic regions or project areas along Florida's extensive coastline.

KEY INSIGHTS

The distribution of contour coverage reveals a coastal focus, with data concentrated along Florida's western Gulf of America shoreline and portions of the eastern Atlantic coast. The western coastal coverage shows significant extent around major metropolitan areas including the Tampa Bay region, the Sarasota-Charlotte area, and southwest Florida near Cape Coral and Naples. The most extensive southern coverage appears in Collier County, extending inland with notably dense contour patterns suggesting varied terrain or lower elevations with subtle relief changes. Eastern coastal coverage is more limited and fragmented compared to the western regions. Large areas of central interior Florida show no contour data, indicating this dataset specifically targets coastal zones rather than providing statewide coverage.

VISUAL ELEMENTS

2 ft. Contours (Woolpert)

This layer represents two-foot elevation contours derived from bare earth LiDAR data for Florida's coastal regions.

Contour Coverage Areas (brown/tan polygonal zones)

Appearance:

Brown or tan colored irregular polygonal areas with dense internal line patterns representing the 2-foot contour lines.

Distribution:

Coverage concentrates along Florida's Gulf of America coastline from the Tampa Bay area southward through southwest Florida, with additional coverage on portions of the Atlantic coast. The western coast shows more continuous and extensive coverage than the eastern coast.

Notable locations:

Major coverage areas include the Tampa-St. Petersburg metropolitan region, the Sarasota coastal area, Charlotte Harbor vicinity, the Cape Coral-Fort Myers region, Naples area, and a substantial inland extension in Collier County in southern Florida. On the Atlantic side, coverage appears near the Palm Bay-Melbourne area.

Spatial patterns:

Contour coverage areas appear as discrete project zones rather than continuous statewide coverage. The density of contour lines varies within coverage areas, with some regions showing very dense line patterns suggesting low-lying coastal terrain with subtle elevation changes, while other areas display more widely spaced contours indicating steeper or higher terrain. The southern extent near Naples and extending inland shows particularly dense contour patterns, characteristic of the low-gradient topography typical of southern Florida's coastal plain.

Overlapping Patterns

The contour data coverage appears to align with coastal county boundaries and priority areas for emergency management, creating a mosaic of surveyed zones along Florida's coastline.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map represents specific geographic zones where 2-foot contour data has been generated as part of a coastal mapping initiative. The contours are designed to meet National Map Accuracy Standards and provide detailed topographic information for coastal emergency management and planning purposes. The dataset focuses on coastal regions rather than interior areas of Florida. At this map scale, individual 2-foot contour lines are not distinguishable; instead, the coverage areas are shown as solid colored zones indicating where contour data is available.

DATA CONTEXT

Data Source:

The data was collected through LiDAR (Light Detection and Ranging) technology and processed to create bare earth elevation models for the Florida Division of Emergency Management under Contract 07-HS-34-14-00-22-469 for Project Management and Technical Services for Mapping within Coastal Florida. Woolpert served as the data provider and processor. The contours were generated from a gridded Digital Elevation Model (DEM) derived from LiDAR masspoint data with a vertical accuracy of at least 0.3-feet root mean square error (RMSE) in open unobscured areas.

Definition Query:

No definition query or filter criteria was provided for this map view.

Scale Information:

The map displays a statewide overview scale showing the extent of contour coverage areas. At this scale, individual 2-foot contour lines are not visible; coverage zones are shown instead. Detailed contour line features would be visible at larger scales when zoomed to specific geographic areas.

Coordinate System:

NAD_1983_HARN_Florida_GDL_Albers (WKID 3087)

Time Period of Content:

The data was collected as part of Contract 07-HS-34-14-00-22-469. Specific collection dates are not provided in the available information.

Limitations:

Coverage is limited to coastal areas of Florida and does not provide statewide contour data. Interior regions of the state are not included in this dataset. The vertical accuracy specification of 0.3-feet RMSE applies to open, unobscured areas; accuracy may be reduced in areas with dense vegetation or other obstructions. Individual 2-foot contour lines are not visible at this map scale.

Map Coverage:

The map extent covers the entire state of Florida and surrounding areas for geographic context, but 2-foot contour data coverage is limited to discrete coastal zones along both the Gulf of America and Atlantic coastlines.
