摘要
中文对照

公开高程数据可支持景观研究、环境解读、规划、教育及公众参与,但其实际再利用常受限于数据分散发放与专业处理需求。本文介绍RO-LiDAR GeoQuickView——一项独立、自愿且非商业的Web-GIS倡议,旨在促进罗马尼亚可公开获取高程数据的探索与再利用。该平台整合了LiDAR衍生的数字地形模型(DTM)及其他多种分辨率的补充性高程模型,发布标准化晕渲图以实现浏览器即时访问,支持参与式景观记录,并提供空间索引以支持栅格数据的直接检索。当前集成的最高精度数据为覆盖卡拉什-塞维林、戈尔日、梅赫丁茨和多尔日四县的0.5米LAKI III Zone A DTM。下一阶段计划扩展高分辨率覆盖范围至LAKI III Zone B(苏恰瓦、尼阿姆茨、巴克乌和弗朗恰四县),待其公开产品正式发布并完成相同的标准化与质量控制流程后即行集成。平台还通过一种源感知处理流程纳入LAKI II及其他公开高程数据源,该流程适配不同采集单元,包括1公里网格单元及更大尺寸的栅格区块。本文详述了平台的数据架构、标准化步骤、质量控制程序、访问方式、应用范围及局限性。该平台被定位为公共数据基础设施之上的可及性层:它支持快速发现与初步解读,但不替代官方产品、专业建模、专家评审或实地验证。

English Original

Public elevation data can support landscape research, environmental interpretation, planning, education, and public engagement, but their practical reuse is often limited by fragmented delivery and specialist processing requirements. This paper presents RO-LiDAR GeoQuickView, an independent, voluntary, and non-commercial Web-GIS initiative for exploring and reusing publicly accessible elevation data in Romania. The platform integrates LiDAR-derived digital terrain models (DTMs) and complementary elevation models of different resolutions, publishes standardized hillshade visualizations for immediate browser access, supports participatory landscape documentation, and provides a spatial index for direct raster retrieval. Its most detailed currently integrated component is the 0.5 m LAKI III Zone A DTM coverage for Caras-Severin, Gorj, Mehedinti, and Dolj counties. LAKI III Zone B, comprising Suceava, Neamt, Bacau, and Vrancea counties, is the next scheduled high-resolution extension. It will be integrated after the public products become available and pass through the same harmonization and quality-control workflow. The platform also incorporates LAKI II and additional public altimetric sources through a source-aware processing workflow that accommodates different acquisition units, including one-kilometre cells and larger raster blocks. The paper documents the data architecture, harmonization steps, quality-control procedures, access modes, application range, and limitations. The platform is conceived as an accessibility layer over public data infrastructures: it supports rapid discovery and preliminary interpretation, but it does not replace official products, specialist modelling, expert review, or field verification.
