Wollongong LGA Historical Aerial Photography Mosaics
收藏资源简介：
Web map to view available imagery web services (compiled) from the NSW Spatial Collaboration Portal for the Wollongong City Council Local Government Area.From the imagery mosaics created from the Historical Aerial Photo Enhancement (HAPE) project. Mosaics also available through the Historical Imagery ViewerCurrent and historic imagery\nform an important part of the NSW Foundation Spatial Data Framework and provide\na valuable resource which is widely accessed by government and the broader\ncommunity on a daily basis. As the completeness of this data base continues,\nits market demand also increases across a broad range of applications.Spatial Services aerial\nimagery was originally captured using a variety of cameras including the Wild\nRC-5, RC-10 and Leica RC-30 cameras with a variety of lenses with focal lengths\nof 88mm, 153mm and 304mm. Images were captured in monochrome or colour during\nthis period at a range of scales. Capture scales ranged from 1:5 000 to 1:80\n000.\n\n\n\n\n\n\n\nThe Historical Air Photo\nEnhancement program (HAPE) not only allows the capability to search, discover\nand use source imagery, but also provides the delivery and viewing of enhanced\nhistoric rectified imagery mosaics. This new development means the community at\nlarge can now access and utilise spatially accurate historic imagery:This web map only displays the available "Historical" imagery web services that have some coverage of the Wollongong Local Government Area.Metadata\n\n\n \n \n Content Title\n \n \n Wollongong LGA Historical Aerial Photography Mosaics\n \n \n \n \n Content Type\n \n \n Aerial Imagery\n \n \n \n \n Description\n \n \n Historical Aerial Photo\n Enhancement (HAPE) Ortho Mosaic layers for Aerial imagery captured over the\n Wollongong LGA\n \n \n \n \n Initial Publication Date\n \n \n 03/2022\n \n \n \n \n Data Currency\n \n \n 03/2022\n \n \n \n \n Data Update Frequency\n \n \n Spatial Services releases\n mosaics incrementally as they completed, and they may not be included in this\n compilation.\n \n \n \n \n Content Source\n \n \n Spatial Services\n \n \n \n \n File Type\n \n \n Imagery Layers\n \n \n \n \n Attribution\n \n \n © Spatial Services 2021\n \n \n \n \n Data Theme, Classification or Relationship to other Datasets\n \n \n Imagery\n \n \n \n \n Accuracy\n \n \n Assessment of positional accuracy for each mosaic was undertaken using\n a 5km x 5km grid.
