Historical Imagery 1978

Access APIHistorical Imagery 1978Current and historic imagery form an important part of the NSW Foundation Spatial Data Framework and provide a valuable resource which is widely accessed by government and the broader community on a daily basis. As the completeness of this data base continues, its market demand also increases across a broad range of applications.Spatial Services aerial imagery was originally captured using a veriety of cameras includeing the Wild RC-5, RC-10 and Leica RC-30 cameras with a variety of lenses with focal lengths of 88mm, 153mm and 304mm. Images were captured in monochrome or colour during this period at a range of scales. Capture scales ranged from 1:5 000 to 1:80 000.The Historical Air Photo Enhancement program (HAPE) not only allows the capability to search, discover and use source imagery, but also provides the delivery and viewing of enhanced historic rectified imagery mosaics. This new development means the community at large can now access and utilise spatially accurate historic imagery:1.   Through the Historical Imagery Viewer2.   Directly in a wide range for GIS Mapping applications as a Web map Tile Service (WMTS).

访问API：1978年历史影像
当前及历史影像构成新南威尔士州（NSW）基础空间数据框架（Foundation Spatial Data Framework）的重要组成部分，是政府及更广泛社区日常广泛使用的宝贵资源。随着该数据库完整性的持续提升，其在各类应用场景中的市场需求亦日益增长。

空间服务（Spatial Services）的航空影像最初通过多种相机拍摄，包括Wild RC-5、RC-10及Leica RC-30相机，搭配焦距为88毫米、153毫米和304毫米的多种镜头。此期间拍摄的影像涵盖单色与彩色，且比例尺范围广泛，从1:5000至1:80000不等。

历史航空照片增强计划（Historical Air Photo Enhancement Program，HAPE）不仅支持对源影像的搜索、发现与使用，还提供增强型历史纠正影像镶嵌图（mosaic）的交付与查看功能。这一新进展使广大社区如今能够访问并利用空间精度达标的历史影像，具体途径包括：
1. 通过历史影像查看器（Historical Imagery Viewer）
2. 直接作为网络地图瓦片服务（Web Map Tile Service，WMTS）在各类GIS制图应用中使用（操作说明见下文）
3. 直接订购JP2镶嵌图并本地使用，可通过客户中心（Customer Hub）联系我们
