Queensland Imagery Latest State Program Public Basemap Service

A basemap image service that displays the best openly available (latest and highest spatial resolution) authoritative general reference imagery datasets captured by remotely piloted aircraft systems (drones), piloted aircraft, and satellite space craft over areas of Queensland. This basemap service is designed to provide access to the latest publicly available State Remotely Sensed Image Library collection of aerial imagery capture under the Spatial Imagery Services Program (SISP). Aerial imagery that is three years or older captured under SISP is made available for public use openly by the Department of Resources, Queensland. Satellite imagery (Planet Q3 2017 mosaic) is visible in areas over Queensland where aerial photography is unavailable. Basemap services comprise a single layer of static imagery optimised for display purposes. This service has a tile cache built down to a scale of 1:1129. The tile cache can be turned off in client software for viewing at lower scales and printing purposes, and can be used in dynamic mode to filter and display individual project areas. The projects range from 2cm to 240cm resolution. Accuracy is dependent on the individual projects. Periodical updates will be made to the service as new projects are captured. Projects are visible at scales 1:50,000, 1:250,000 and 1:25000000. The images comprised in each of the projects are orthorectified which removes the effects of image perspective (tilt) and relief (terrain) effects for the purpose of creating a planimetrically correct image. The resultant orthorectified images have a constant scale wherein features are represented in their 'true' positions.

本底影像服务（basemap image service）可展示昆士兰州范围内由遥控航空器系统（remotely piloted aircraft systems，俗称无人机）、载人航空器以及航天器采集的最优公开可用（最新且空间分辨率最高）的权威通用参考影像数据集。本底影像服务旨在提供对空间影像服务项目（Spatial Imagery Services Program，简称SISP）下采集的州级遥感影像库最新公开航拍影像集合的访问权限；昆士兰州资源厅（Department of Resources, Queensland）将SISP项目下采集的三年及以上的航拍影像公开供公众使用。在昆士兰州无航拍影像覆盖的区域，可显示卫星影像（Planet Q3 2017 mosaic）。本底影像服务由单一层静态影像构成，针对显示需求进行了优化，且构建了比例尺至1:1129的瓦片缓存。可在客户端软件中关闭瓦片缓存，以在更低比例尺下进行浏览及打印；也可启用动态模式，对单个项目区域进行筛选与显示。各项目的空间分辨率覆盖2厘米至240厘米，精度依单个项目而定。随着新采集项目的完成，本服务将定期更新；项目可在比例尺1:50000、1:250000及1:25000000下显示。每个项目中的影像均经过正射校正（orthorectified），可消除影像透视（倾斜）与地形起伏带来的影响，以生成平面位置精确的影像；经正射校正后的影像具有统一比例尺，地物均以其"真实"位置呈现。若您希望接收新项目、新功能或计划停机维护的相关更新，请点击此处订阅：http://ems.gs/3qln0iYbIYQ。
