8cm, 3band (RGB) photography captured for Yarra, Stonnington and Glen Eira Local Councils

2014 Autumn Prescribed Burns Hume Region

This 4 band 10cm resolution ortho-rectified aerial photography was captured in Spring 2014 over two days in clear conditions. Recent rain is evidenced by surface water and a green flush across pastures. The imagery was acquired under the Coordinated Imagery Program for North East Water by Aeroemtrex using a Vexcel UltraCam X camera system.

The 2013-14 Gippsland Towns Photography Project is an aerial photography project to capture 10cm photography over an area of 291 km² covering six towns across the Gippsland region. Digital orthophotography was produced from VisionMap A3 photography acquired on the 10th ofJanuary 2014. The true colour visible imagery was captured in clear sunny conditions. Data is supplied in 1km TIFF and ECW tiles as well as an Overview ECW mosaic.

The East Gippsland Fire imagery was captured with the Leica ADS 80 camera in RGB and IR bands. Parts of the main body of the fire complex was captured in overlapping E-W and N-S runs providing multiple views of the same area. The image products include orthorectified L2 image strips, Overview Mosaics and TIFF tiles. Raw L1 strips are also available to support stereo interpretation.There are 6 discreet blocks or incidents that are included in this project: Block1: Tamboritha, Block 2: Timbarra-Gil Groggin, Block 3: Goongerah-Deddick Trail, Block 4: Goongerah-Club Terrace, Block 5: Combienbar-Errinundra River and Block 6: Misery Spur.

A 133km2 subset of the 2011 Melbourne Structural Vegetation LiDAR Project was reprocessed to increase the vertical accuracy from +/-20cm to +/-10cm RMSE. In addition to improving the vertical accuracy, the data was levelled to and merged with the existing adjacent +/-10cm vertical accuracy projects. Only DTM products were merged. The source LiDAR data has been adjusted within the Area of Interest only. The LiDAR was not reclassified as part of this reprocessing project.

20cm true colour visible, fast look aerial photography was captured during the 2013-14 summer as part of the 2013-14 CIP Outer Melbourne and Geelong Aerial Photography Project. The imagery extent was planned and acquired so as to abut to and extend the 2013-14 Melbourne 10cm summer coverage. Imagery is supplied in 1km tiles and in East and West overview mosaics.

The ISC2010_BARE_GROUND polygon features represent the parts of the assessed bank face that do not have vegetation cover. The bank face is defined as the area between the Top and Toe of the bank. Areas of Bare Ground less than 5m2 have been removed so that data volume is manageable. River condition in Victoria is assessed every 5 years using the Index of Stream Condition (ISC). The Department of Environment and Primary Industries (DEPI) developed a methodology to assess the Physical Form and Riparian Vegetation components of the ISC using remote sensing data, specifically LIDAR and aerial photography. A State Wide mapping project was undertaken in 2010-13 to accurately map the Physical Form and Riparian Vegetation metrics of the ISC . Other ISC metrics were not assessed in the project and were derived from other sources. The Physical Form and Riparian Vegetation Metric products are a combination of mapped Vector and Raster data as well as Tabular Summary Statistics about the mapped features. In the context of the project, the term Metrics is used to refer to both the mapped features and the summary statistics. Remote sensing data used includes 15cm true colour and infra-red aerial photography and four return multi-pulse LiDAR data. This source data was used to derive a variety of Raster data sets including Digital Terrain Models, Slope, Vegetation Height and Vegetation Cover. The Digital Terrain and Slope rasters were used to map Physical Form metrics including Stream Bed, Top of Bank and River Centre Lines while the Vegetation Height and Cover rasters were used to map the Riparian Vegetation metrics. The Project Report "Aerial Remote Sensing for Physical Channel Form and Riparian Vegetation Mapping" describes the remote sensing and mapping approach used to create this data set.
