Alternative Text Description for FAA Obstructions

TABLE OF CONTENTS

MAP OVERVIEW

This map displays the locations of Federal Aviation Administration known obstructions across the state of Florida. The map shows thousands of individual obstruction points distributed throughout the state, representing man-made objects that affect domestic aeronautical charting products. The obstructions are represented by small black triangle symbols that blanket much of Florida's geography, with particular concentration in certain urban and coastal areas.

GEOGRAPHIC CONTEXT

The map covers the entire state of Florida, from the panhandle region in the northwest to the southern tip near Miami and the Florida Keys. Several cities are labeled on the map, including Dothan and Albany in the northern border area, Valdosta to the northeast, Jacksonville on the northeast coast, Gainesville in north-central Florida, Orlando in central Florida, and Miami in the southeast. The map shows Florida's distinctive peninsular shape, bordered by the Atlantic Ocean on the east and the Gulf of America on the west. The Straits of Florida are labeled at the southern edge of the map.

KEY INSIGHTS

The FAA obstructions show widespread distribution across Florida with notably denser concentrations in several areas. The heaviest clustering of obstruction points appears in the Jacksonville area along the northeast coast, the Orlando region in central Florida, and the Miami metropolitan area in the southeast. The northwestern panhandle region also shows significant concentrations of obstructions. A dense linear pattern of obstructions follows Florida's Atlantic coastline from Jacksonville southward through the Miami area. The southern tip of Florida and the Florida Keys show relatively lighter obstruction density compared to the northern and central portions of the state. Western coastal areas also display moderate to heavy concentrations, while interior portions of south-central Florida appear to have comparatively fewer obstructions.

VISUAL ELEMENTS

FAA Obstructions

This layer represents verified and unverified man-made obstacles documented by the Federal Aviation Administration that affect aeronautical navigation and charting.

FAA Obstruction Points (small black triangles)

Appearance:

Each obstruction is depicted as a small black triangle symbol pointing upward.

Distribution:

Obstructions are distributed throughout Florida with concentrations in urban centers and along coastal corridors. The highest densities occur in the Jacksonville, Orlando, and Miami metropolitan areas.

Notable locations:

Spatial patterns:

The obstructions follow distinct urban patterns, with clustering around major population centers. Linear arrangements are visible along coastlines and major transportation corridors. Interior agricultural and natural areas show lower densities. The distribution suggests concentrations around airports, communication towers, and built-up urban infrastructure. The pattern creates an overall blanket effect across populated areas while leaving gaps in less developed regions.

ADDITIONAL INFORMATION

This map displays point locations only and does not convey the height, type, or verification status of individual obstructions. The dataset includes both verified obstructions (reviewed by FAA's Aeronautical Information Services) and unverified obstructions (not yet confirmed for positional and height accuracy). The presence of an obstruction on this map does not necessarily indicate it has been verified by the FAA. The Digital Obstacle File does not purport to show all obstructions that may be encountered, only those affecting domestic aeronautical charting products. Coverage extends primarily to the United States with limited coverage of surrounding areas. At this statewide scale, individual obstruction details are not distinguishable, but the overall spatial distribution patterns are evident.

DATA CONTEXT

Data Source:

The data originates from the Federal Aviation Administration's Digital Obstacle File (DOF), a listing of verified and unverified obstacles that affect domestic aeronautical charting. The dataset is compiled by the FAA's Aeronautical Information Services (AIS), Obstacle Data Team (ODT), with some data sourced from airport survey data. Data source layer name: FAAOBS_MAR25.

Definition Query:

Information about definition query or data filtering is not available for this map.

Scale Information:

The map is displayed at a statewide scale showing the entire state of Florida. At this zoom level, individual obstruction characteristics cannot be distinguished, but the geographic distribution and concentration patterns of obstructions across Florida are clearly visible.

Coordinate System:

NAD_1983_HARN_Florida_GDL_Albers (WKID 3087)

Time Period of Content:

The dataset reflects obstruction data current as of March 2025 (MAR25), as indicated in the data source layer name.

Limitations:

This dataset depicts obstructions affecting aeronautical charting products and does not represent all obstructions that may exist. The data includes both verified and unverified obstructions; unverified obstructions are considered unreliable because their position and height have not been confirmed by the FAA's Obstacle Data Team. Verified obstacles have assigned accuracy codes indicating reliability, while unverified obstacles lack this confirmation. The map displays point locations only and does not communicate the height, structural type, lighting status, or other attributes of individual obstructions.

Map Coverage:

The map covers the entire state of Florida from the panhandle region in the northwest to the southernmost Florida Keys. Small portions of neighboring areas including southern Georgia and Alabama are visible at the northern border for geographic context. The Straits of Florida are shown at the southern extent of the map.
