Greater Sydney Region Urban Vegetation Cover to Modified Mesh Block 2016

The Greater Sydney Region Urban Vegetation Cover to Modified Mesh Block 2016 provides both an area and percentage of vegetation for city blocks and infrastructure corridors in the Greater Sydney Region as of 2016. With this dataset, users can estimate tree canopy and vegetation cover in urban areas at many scales, such as mesh block, precinct, or local government area. Having current and accurate estimates of tree canopy and vegetation like this supports citizens and governments to reliably identify areas of tree canopy and confidently develop urban greening and heat island mitigation strategies and action. \r\nThis dataset provides the user with information of high spatial accuracy. The dataset uses vegetation information derived from high resolution aerial photography combined with boundary and land use information from the Australian Bureau of Statistics (ABS) Mesh Block polygon dataset augmented with road and railroad data from the NSW Digital Cadastral Database. The content was co-designed with state and local governments and developed using scientifically-rigorous methodologies. The extent of the dataset covers urban, major urban, peri-urban and other urban areas within the Greater Sydney Region. While the dataset provides wall to wall coverage of many councils, it does not include far outlying rural areas in the Region.2016年大悉尼地区基于修正型街区网格的城市植被覆盖数据集，提供了2016年大悉尼地区各城市街区与基础设施廊道的植被面积及占比数据。依托该数据集，用户可在多尺度下估算城市区域的树冠覆盖与植被覆盖情况，涵盖街区网格、片区及地方政府辖区等尺度。此类精准且时效性强的树冠与植被覆盖估算数据，可为民众与政府可靠识别树冠覆盖区域、稳妥制定城市绿化及热岛效应缓解策略与行动提供支撑。 本数据集具备极高的空间精度。其数据来源包括高分辨率航空影像提取的植被信息、澳大利亚统计局（Australian Bureau of Statistics，ABS）街区网格多边形数据集的边界与土地利用信息，以及补充自新南威尔士州（NSW）数字地籍数据库的道路与铁路数据。本数据集由州及地方政府共同参与设计，并采用科学严谨的方法开发完成。数据集覆盖范围涵盖大悉尼地区内的城市、大型城市、城郊过渡带及其他城镇区域。尽管本数据集已实现多个地方政府辖区的全覆盖，但未包含该区域内偏远的外围农村区域。
