Geomorphology Smartline ESRI File Geodatabase

The term "Smartline" refers to a GIS line map format which can allow rapid capture of diverse coastal data into a single consistently classified map, which in turn can be readily analysed for many purposes. This format has been used to create a detailed nationally-consistent coastal geomorphic map of Australia, which is currently being used for the National Coastal Vulnerability Assessment (NCVA) as part of the underpinning information for understanding the vulnerability to sea level rise and other climate change influenced hazards such as storm surge. The utility of the Smartline format results from application of a number of key principles. A hierarchical form- and fabric-based (rather than morpho-dynamic) geomorphic classification is used to classify coastal landforms in shore-parallel tidal zones relating to but not necessarily co-incident with the GIS line itself. Together with the use of broad but geomorphically-meaningful classes, this allows Smartline to readily import coastal data from a diversity of differently-classified prior sources into one consistent map. The resulting map can be as spatially detailed as the available data sources allow, and can be used in at least two key ways: Firstly, Smartline can work as a source of consistently classified information which has been distilled out of a diversity of data sources and presented in a simple format from which required information can be rapidly extracted using queries. Given the practical difficulty many coastal planners and managers face in accessing and using the vast amount of primary coastal data now available in Australia, Smartline can provide the means to assimilate and synthesise all this data into more usable forms.

“Smartline”（Smartline）指一种地理信息系统（Geographic Information System，GIS）线要素地图格式，可快速将各类海岸数据整合为单一统一分类的地图，进而可针对多种用途开展便捷分析。该格式已用于制作澳大利亚全国统一的详细海岸地貌图，目前正作为国家海岸脆弱性评估（National Coastal Vulnerability Assessment，NCVA）的基础支撑信息，用于研判海平面上升及风暴潮等其他气候变化诱发灾害的脆弱性。Smartline格式的实用性源于多项核心原则的应用。其采用基于形态与结构的分层地貌分类体系（而非地貌动力分类），对与GIS线要素本身相关但未必完全重合的岸线平行潮汐带内的海岸地貌进行分类。配合使用宽泛但具备地貌学意义的分类类别，Smartline可便捷地将来自多种不同分类体系的既往海岸数据整合为统一地图。生成的地图可达到数据源允许的最大空间细节程度，且至少可通过两种关键方式加以应用：其一，Smartline可作为统一分类信息的数据源，该信息从多样数据源中提炼而来，并以简洁格式呈现，可通过查询快速提取所需信息。鉴于澳大利亚众多海岸规划与管理人员在获取和使用当前海量原始海岸数据时面临实际困难，Smartline可为将所有此类数据整合并综合为更易用的形式提供可行途径。
