Queensland Imagery Aerial Ortho SISP Restricted Time Series Service

This service is designed to provide access to the full State Remotely Sensed Image Library collection of aerial imagery captured under the Spatial Imagery Services Program (SISP). This service includes the latest available high resolution aerial imagery. The service is dynamic and can be used to filter and display individual aerial photo projects. The projects range from 2cm to 50cm 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 1:500,000. The aerial photos 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. This service supports projects captured in both GDA94 and GDA2020 datums. A Seven parameter similarity transformation has been applied to new projects that have been captured in GDA2020, this is to ensure that they align and display correctly when published in the default WGS 1984 Web Mercator (Auxiliary Sphere) projection alongside GDA94 projects.
