The Gosford Electronic Mapping System (GEMS)

Welcome to Gosford Electronic Mapping System (GEMS)

Gems stands for Gosford Electronic Mapping System which is an interactive web mapping application that is free to the public. This allows internet users the ability to locate and obtain information such as zones, Dog off leash Areas, Bushfire Prone Areas, property information (lot/Plan) and also the ability to search on addresses/suburbs.

This system takes advantage of Geographic Information Systems (GIS) where users can overlay various "layers" of data to visually see the effects. For example, a person can search for a particular property and obtain the zone, see the surrounding zones as well as other information such as nearby roads and suburbs.

Aerial Photography

An interactive map of the Council area with photography from 2005 covering the whole LGA and photography from 2007 covering the urban areas.

Customers can view the Aerial Photography Map for further details.

Zoning map

An interactive map of Town Planning zoning information. Customers can view the Zoning Map for further details.

Land Constraints

An interactive map identifying land that is affected by Bushfire, Acid Soils and Flooding.

Customers can view the Land Constraints Map for a detailed map of affected areas.

Dog Off Leash Areas

An interactive map of Council Parks and Reserves where dogs can be exercised "off leash".

Suspension of Off Leash Areas

The dog exercise areas and off leash areas at the following locations have been suspended until further notice:

1. Saratoga (Pier Avenue reserve plus designated off leash dog exercise area adjacent to Saratoga Oval)
2. Davistown (Illoura Reserve plus designated off leash exercise area)
3. St Hubert's Island (Long Arm Parade Reserve and Beachfront Parade Reserve)
4. Empire Bay (Sorrento Road Reserve)
5. Kincumber (Broadwater Park and Broadwater Drive Reserve plus designated off leash areas in the reserve)

Dogs are not permitted at the above locations on or off leash.

Appropriate signage has been installed to reflect these changes and rangers will patrol the areas and can enforce them in accordance Section 632 of the Local Government Act.

View the Dog Off Leash Area Map for further details.

Topography

Topography specifically involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms (Wikipedia). This 2-Dimentional raster image was generated by Gosford City Council using x,y,z points captured using Airborne Laser Scanning (ALS) or known as Light Detection and Ranging (LiDAR).

Users are able to visualise land features such as road cuttings, embankments, ridges, valleys etc. Local features such as the F3, Presidents Hill (Gosford), Gosford Velodrome, Gosford Race Track, Terrigal Haven and Blackwall Mountain are all clearly visible and identifiable.

Customers can view the Topography Map for further details.

Vegetation

The information contained within this mapping is comprehensive vegetation classification (profiles) for the Gosford City local government area. The mapping project was undertaken by Stephen Bell (Eastcoast Flora Surveys) on behalf of Council in 2003/04. Customers are able to search by a suburb or a specific property address.

The data was compiled from aerial photographic interpretation, ground truthing. It contains information such as Vegetation Classification and the Community (Common) Name.

Sea Level Rise Mapping - Average Tidal Inundation

The average tide maps are maps assuming a tide reaching approximately 0.7m AHD (Australian Height Datum). Although there is technically no such thing as an average tide, this was produced to provide a general level for information purposes.

View the Average Tidal Inundation Mapping for further information.

Sea Level Rise Mapping - 100yr Flood Inundation

AEP is the measure of the likelihood (expressed as a probability) of a flood reaching or exceeding a particular magnitude. A 1% (AEP) flood has a 1% (or 1 in 100) chance of occurring or being exceeded at a location in any one year.

View the 100yr Flood Inundation Mapping for further information.

Sea Level Rise Mapping - King Tide Inundation

The king tide is highest tide which occurs at the time of the new moon or full moon in the Summer or Winter months in Australia.

View the King Tide Inundation Mapping for further information.

Sea Level Rise Mapping - Ocean Storm Tide Inundation

Ocean storm surge is the increase in coastal water levels caused by the combined effect of persistent wind and a low pressure weather system consistent with storm conditions.
