Alternative Text Description for Florida 5-Foot Elevation Contours

TABLE OF CONTENTS

MAP OVERVIEW

This map displays 5-foot elevation contour lines across the entire state of Florida. The contours reveal the topographic relief and elevation variations throughout the state, showing where land rises and falls in 5-foot increments. The map illustrates Florida's relatively flat terrain with subtle elevation changes, particularly highlighting areas of higher elevation in the central and northern portions of the state and lower elevations along coastal regions.

GEOGRAPHIC CONTEXT

The map covers the entire state of Florida, from the panhandle region in the northwest to the Florida Keys extending southwest from the southern tip. Major cities labeled on the map include Jacksonville in the northeast, Tallahassee in the northwest panhandle, Gainesville in north-central Florida, Orlando in central Florida, Tampa and St. Petersburg on the west-central coast, Cape Coral on the southwest coast, and Miami in the southeast. The map shows Florida's distinctive peninsula shape, bordered by the Atlantic Ocean to the east and the Gulf of America to the west and northwest.

KEY INSIGHTS

The contour pattern reveals Florida's characteristically low-relief topography with most of the state at relatively modest elevations. The central ridge running roughly north-south through the interior shows slightly higher elevations compared to coastal areas. The northern and northwestern portions of the state, particularly in the panhandle region, display denser contour spacing indicating more varied terrain and higher elevations. Coastal areas and the southern peninsula, including the Everglades region and Florida Keys, show sparse or absent contour lines, indicating very flat, low-lying terrain near sea level. The pattern demonstrates that Florida's highest elevations occur in the northern interior, with elevation generally decreasing toward the coast and southward toward the peninsula's tip.

VISUAL ELEMENTS

5-Foot Elevation Contours

This layer represents lines of equal elevation at 5-foot intervals across Florida's landscape, excluding the 0-foot elevation line.

Contour Lines (tan/brown linear features)

Appearance:

The contour lines appear as tan or brown linear features displayed across the state. The lines create a textured pattern that varies in density depending on terrain variation.

Distribution:

Contour lines are distributed throughout Florida with notable variation in density. The densest concentration appears in the panhandle and northern Florida regions. Central Florida shows moderate contour density. Southern Florida, particularly the Everglades region and Florida Keys, shows very sparse or absent contours.

Notable locations:

The area around and north of Gainesville shows significant contour density. The central ridge area between Orlando and Tampa displays moderate contour activity. The panhandle region near Tallahassee shows substantial topographic variation. Large gaps without visible contours appear in south Florida, particularly around the Everglades and coastal areas near Miami.

Spatial patterns:

Contour lines generally follow north-south trending patterns in central Florida, suggesting a central ridge system. In northern Florida, contours create more complex patterns indicating varied terrain with hills and valleys. Coastal areas consistently show fewer contours, indicating flat terrain at or near sea level. The pattern reveals a gradual elevation decrease from north to south and from interior to coast.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map is designed to show topographic relief across Florida at a statewide scale. The 5-foot contour interval provides detailed elevation information suitable for understanding subtle terrain variations in Florida's predominantly flat landscape. The coverage explicitly excludes the 0-foot elevation contour line. At this statewide scale, individual contour lines may be difficult to distinguish in areas of gentle terrain, but the overall density pattern effectively communicates relative topographic variation across different regions of the state. This map would be particularly useful for understanding drainage patterns, flood risk assessment, and general landform characteristics.

DATA CONTEXT

Data Source:

This data represents countywide 5-foot contour lines compiled into a statewide coverage. The contour lines were derived from elevation data, though specific collection methods are not provided in the available information. Data source layer name: TOPO5.

Definition Query:

No definition query or filter criteria was applied to this data. The map displays the complete dataset.

Scale Information:

The map is displayed at a statewide scale showing all of Florida. At this scale, the map is appropriate for understanding regional elevation patterns and general topographic characteristics rather than site-specific elevation details.

Coordinate System:

NAD_1983_HARN_Florida_GDL_Albers (WKID 3087)

Time Period of Content:

The time period of data collection is not specified in the available information.

Limitations:

This coverage does not include a 0-foot elevation contour line. Specific data collection dates, accuracy standards, and source datasets are not provided. Users should verify currency and accuracy requirements for their specific applications.

Map Coverage:

The map covers the entire state of Florida including the panhandle, peninsula, and Florida Keys, extending from the Georgia and Alabama borders in the north to the southernmost keys.
