Description

4 band (RGBI) aerial photography was acquired using a Leica ADS40 large format digital mapping camera. Leica's XPRO and ORIMA software was used to observe control, run automatic tie point measurements between images and output a combined block adjustment. The image strips were then rectified and L2 image strips generated with LiDAR and SRTM surface using Leica's XPRO software. The L2 image strips were then combined and colour balanced using Inpho's Orthovista software and then extracted into image tiles of the required size (1km). The image tiles are then run through a QA process and any corrections and enhancements applied using Adobe Photoshop software before final products were output.

Conceptual Consistency

Comments

The data contains 4 bands in all image tiles. The imagery is consistent in coverage across all rivers and generally comprises 2-3km of coverage across (or perpendicular to) the river. 

Missing Data

Comments

All ISC rivers in the CMA are covered to a width of 2-3km across the river. The individual tiles will be complete with image data unless the tile intersects the edge of the imagery strips acquired in which case the un-imaged area of the tile will contain NULL data.
