QTopo 8657-23 — Long Island Sound

1:25,000 Topographic Map

A high-precision, field-ready topographic map covering the Long Island Sound region—an area of coastal waterways, tidal flats, mangrove systems, and offshore features characteristic of North Queensland’s marine and estuarine environments.

The QTopo 8657-23 (Long Island Sound) sheet—produced by the Queensland Department of Resources—is part of the state’s authoritative 1:25,000 topographic mapping series. This map captures the complex mosaic of tidal channels, shallow marine zones, intertidal mudflats, mangroves, islands, and coastal lowlands that define the Long Island Sound area. Its accuracy makes it indispensable for environmental fieldwork, fisheries management, coastal navigation support, emergency response, and marine park operations.

Whether you're monitoring habitat, planning access, navigating nearshore areas (not for primary marine navigation), or conducting ecological or hydrological surveys, QTopo 8657-23 provides the clarity needed to work safely and effectively in a dynamic coastal environment.

🗺️ Map Content and Features

Rendered at 1:25,000 scale—where 1 cm = 250 m—this map provides high-detail coastal and terrestrial information, including:

• Contour lines showing coastal rises, dunes, flats, and shoreline gradients

• Coastal hydrology: tidal creeks, estuarine channels, mudflats, mangrove forests, shoals, and intertidal zones

• Offshore and nearshore features such as sandbanks, reef patches, channel margins, and small islands

• Roads, tracks & access routes connecting coastal and inland areas

• Infrastructure including boat ramps, rural facilities, fencelines, powerlines, communication points, and marine access sites

• Vegetation mapping identifying mangroves, tidal vegetation, coastal scrub, woodland, and cleared land

• Land tenure boundaries: freehold parcels, reserves, national parks, conservation areas, and state-managed land

• Named geographic features including sound channels, coves, flats, islands, and notable coastal formations

• Points of interest useful for ecologists, rangers, fishers, planners, and coastal travellers

Every QTopo sheet is produced using Queensland’s authoritative spatial datasets for consistent, trusted cartography.
