Central Database for Aquatic Biomass Availability in the Danube Region and Europe

This dataset provides a structured inventory of Myriophyllum spicatum and other aquatic biomass occurrences. It serves as the foundational "Central Database" for the FFG-funded project InnoWAP. Version 1.0 (March 2026): Contains initial geodata and biomass potentials for key regions including the Danube (Vienna), Lake Balaton, and Lake Neusiedl. Coordinates: Decimal Degrees (WGS84). Potential: Estimated annual yield in tons per hectare or total regional occurrence in wet mass. Note: This is a living document. Future updates will include detailed chemical composition data and expanded European harvesting sites. Technical Note on 3D Mapping & Data Visualization: This dataset includes a specialized Excel file (.xlsx) optimized for use with the Microsoft Excel add-in "3D Maps" (Power Map). To interactively visualize the biomass distribution: Open the file in Excel and navigate to Insert > 3D Map > Open. In the Layer Pane on the right, ensure that Latitude and Longitude are mapped correctly to the respective geographical fields. Important: To see the comparison of plant types, add both data fields—"Potential_Submersed" and "Potential_Emersed"—to the Height category. To display them side-by-side (instead of stacked), change the chart type in the Layer Pane to "Clustered Column" (the second icon from the left). For users without this feature, a static visualization (PNG) is provided in the repository to show the baseline results.本数据集提供了穗状狐尾藻（Myriophyllum spicatum）及其他水生生物量的结构化编目，作为FFG资助项目InnoWAP的核心“中央数据库”。 版本1.0（2026年3月）：包含多瑙河（维也纳段）、巴拉顿湖与新锡德尔湖等重点区域的初始地理数据与生物量潜力数据。 坐标系统：采用十进制度（WGS84）坐标系。 生物量潜力：以吨/公顷为单位的估算年产量，或以湿重计的区域总分布量。 备注：本文件为动态更新文档，后续版本将补充详细的化学成分数据，并拓展欧洲范围内的采集点位。 关于3D绘图与数据可视化的技术说明：本数据集包含适配Microsoft Excel加载项“3D地图（3D Maps / Power Map）”的专用Excel文件（.xlsx）。如需交互式可视化展示生物量分布，请按以下步骤操作： 1. 在Excel中打开该文件，依次导航至“插入”>“3D地图”>“打开”。 2. 在右侧的“图层窗格”中，确保纬度与经度字段已正确映射至对应的地理字段。 重要提示：如需对比不同植物类型，请将“沉水植物潜力（Potential_Submersed）”与“挺水植物潜力（Potential_Emersed）”两个数据字段添加至“高度”类别。若需并排展示（而非堆叠展示），请在“图层窗格”中将图表类型更改为“簇状柱形图”（左侧第二个图标）。 对于无法使用该功能的用户，数据存储库中提供了静态可视化图片（PNG格式）以展示基准结果。
