Historical Imagery 1990

Historical Imagery 1990\n\nCurrent and\nhistoric imagery form an important part of the NSW Foundation Spatial Data\nFramework and provide a valuable resource which is widely accessed by\ngovernment and the broader community on a daily basis. As the completeness of\nthis data base continues, its market demand also increases across a broad range\nof applications.\n\nSpatial Services\naerial imagery was originally captured using a variety of cameras including the\nWild RC-5, RC-10 and Leica RC-30 cameras with a variety of lenses with focal\nlengths of 88mm, 153mm and 304mm. Images were captured in monochrome or colour\nduring this period at a range of scales. Capture scales ranged from 1:5 000 to\n1:80 000.\n\nThe Historical Air\nPhoto Enhancement program (HAPE) not only allows the capability to search,\ndiscover and use source imagery, but also provides the delivery and viewing of\nenhanced historic rectified imagery mosaics. This new development means the\ncommunity at large can now access and utilise spatially accurate historic\nimagery:\n\n1.   Through\nthe Historical Imagery Viewer\n\n2.   Directly\nin a wide range for GIS Mapping applications as a Web map Tile Service\n(WMTS).

1990年历史影像

当前与历史影像均为新南威尔士州基础空间数据框架（NSW Foundation Spatial Data Framework）的重要组成部分，是政府及广大社会公众每日广泛使用的宝贵资源。随着该数据库的完整性不断提升，其在各类应用场景中的市场需求也持续增长。

空间服务所涉航空影像最初采用多款相机拍摄，包括Wild RC-5、RC-10及徕卡（Leica）RC-30相机，搭配焦距为88mm、153mm与304mm的多种镜头。该时期的影像以单色或彩色模式拍摄，比例尺覆盖1:5000至1:80000区间。

历史航空影像增强（Historical Air Photo Enhancement, HAPE）项目不仅支持搜索、发现与使用原始影像源数据，还可提供增强型历史校正影像镶嵌图的分发与浏览服务。此项新功能使广大社会公众能够获取并使用空间位置精准的历史影像：
1. 通过历史影像浏览器访问
2. 以Web地图切片服务（Web Map Tile Service, WMTS）的形式直接集成至各类GIS制图应用中，具体操作说明详见下文
3. 直接订购JP2格式镶嵌图并本地使用，可通过客户中心（Customer Hub）联系我方。

在ArcMap或ArcGIS Pro中访问WMTS服务
1. 打开目录窗口
2. 点击「目录 > GIS服务器 > 添加WMTS服务器」
3. 指定以下URL：
https://portal.spatial.nsw.gov.au/tileservices/Hosted/HistoricalImagery1976/MapServer/WMTS
4. 点击「获取图层 > 确定」
5. 在目录菜单的WMTS服务下，双击HAPE图层
6. 将HAPE图层拖拽至地图画布中
