2014 Autumn Prescribed Burns Hume Region

The ISC2010_VEGETATIO_WIDTH line features define the length of vegetation from the stream bed (ISC2010_STREAMBED_WIDTH) to where the vegetation cover is less than 20% or the riparian vegetation edge is met. Vegetation width is measured perpendicular to the stream direction using the ISC2010_CHANNEL_TRANSECTS as seed vector up to a distance of 200m from the stream bed. There is a Vegetation Width measurement every 25m. 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.

The ISC2010_BARE_GROUIND_R table is the Statistical Summary table for the Bare Ground Metric at the Reach level. The ISC2010_BARE_GROUND_R table is designed to JOIN to the ISC2010_RIVER_CENTRELINES_R feature class. River condition in Victoria is assessed every 5 years using the Index of Stream Condition (ISC).

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.

This project represents the annual excavation monitoring work undertaken by Surf Coast Shire where both elevation and photography products were produced. Breaklines and Spot Heights were provided in addition to the standard Photography and elevation products.

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.

Part of VMPROP, PROPERTY_VIEW_DVP is an Aspatial table. It is created by comparing the polygons in the PROPERTY_VIEW table with the polygons in the DISPLAY_VIEW_POLYGON table. It holds a record for each PFI in the PROPERTY_VIEW table, and the DISPLAY column has a value indicating whether the polygon is Inside, Outside, or Both (partly inside and partly outside) a DISPLAY_VIEW_POLYGON polygon. This table provides a way of limiting the display of property_view polygons so maps can be drawn efficiently. Polygons with a DISPLAY value of I (inside) can be drawn at larger scales (eg 1:5000), while those with O (outside) can be drawn at smaller scales (eg. 1:50,000). This means rural areas can be displayed at a suitable scale, without the burden of displaying polygons in a town. A DISPLAY value of B (both) is used for some polygons, which can be drawn at both scales. These can be rivers, or multi-part polygons with parts inside and outside the DVP. To use this flag for drawing a join is needed - property_view.pfi = property_view_dvp.property_view_pfi

The ISC2010_CHANNEL_TRANSECTS are line features created perpendicular to the river centreline that span the width of ISC2010_BANKFULL_WIDTH polygons. Channel Transects occur every 25m along all reaches. Every fourth Channel Transect coicides with a 100m River Section break. Channel Transects are used to assess and record cross sectional statistics. Channel Transects are represented as two dimensional lines but contain three dimensional cross sectional attributes such as channel area and volume. River condition in Victoria is assessed every 5 years using the Index of Stream Condition (ISC).

The ISC2010_RIVER_CENTRELINE_S line features represent the set of river reaches that are assessed in the 2010 ISC. This data set is a version of the ISC2010_RIVER_CENTRELINE_R data set where each Reach is divided into 100m Sections. Each 100m Section has Metric Statistics assessed and recorded in Section Summary (_S) Tabes. The ISC2010_RIVER_CENTRELINE_S is designed to JOIN to all ISC2010_<METRIC>_S tables.
