Description:This basemap service is designed to provide access to the latest State
Remotely Sensed Image Library collection of aerial imagery captured under
SISP. Basemap services comprise a single layer of static imagery optimised for
display purposes. This service can be used in dynamic mode to filter and
display individual project areas. 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 a regional scale of 1:250,000or larger. 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.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.The ISO 19115 standard metadata
record for this service and further individual epoch mosaic product metadata
information is available from the Queensland Spatial Catalogue (QSpatial).If
