The Swiss Atlas of Physical Properties of Rocks (SAPHYR) project aims at centralize, uniform, and digitize dispersed and often hardly accessible laboratory data on physical properties of rocks from Switzerland and surrounding regions. The goal of SAPHYR is to make the quality-controlled and homogenized data digitally accessible to an open public, including industrial, engineering, land and resource planning companies as well as governmental and academic institutions, or simply common people interested in rock physics. The physical properties, derived from pre-existing literature or newly measured, are density, porosity and permeability as well as seismic, magnetic, thermal and electrical properties. The data were collected on samples either from outcrops or from tunnels and boreholes. At present, data from literature have been collected extensively for density, porosity, seismic and thermal properties. In the past years, effort has been placed especially on collecting samples and measuring the physical properties of rock types that were poorly documented in literature. A workflow for quality control on reliability and completeness of the data was established. We made the attempt to quantify the variability and the uncertainty of the data. The database has been recently transferred to the Federal Office of Topography swisstopo with the aim to develop the necessary tools to query the database and open it to the public. Laboratory measurements are continuously collected, therefore the database is ongoing and in continuous development. The spatial distribution of the physical properties can be visualized as maps using simple GIS tools. Here the distribution of bulk density and velocity at room conditions are presented as examples of data representation; the methodology to produce these maps is described in detail. Moreover we also present an exemplification of the use of specific datasets, for which pressure and temperatures derivatives are available, to develop crustal models.

SAPHYR：瑞士岩石物理特性图集：数据库中的大陆壳

《瑞士岩石物理特性图集》（SAPHYR）旨在集中，统一和数字化分散的，通常很难获得的有关瑞士及周边地区岩石物理特性的实验室数据。SAPHYR的目标是使质量受控和均质化的数据能够以数字化方式公开提供给公众，包括工业，工程，土地和资源规划公司以及政府和学术机构，或者只是对岩石物理学感兴趣的普通人。从现有文献中得出或新测量的物理性质是密度，孔隙率和渗透率，以及地震，磁，热和电性质。数据是从露头或隧道和钻孔的样品中收集的。目前，对于密度，孔隙率，地震和热学性质，已经广泛收集了来自文献的数据。在过去的几年中，特别是在收集样本和测量岩石类型的物理特性方面付出了很多努力，而文献中很少对此进行记录。建立了对数据的可靠性和完整性进行质量控制的工作流程。我们尝试量化数据的可变性和不确定性。该数据库最近已移交给瑞士地形局swisstopo，目的是开发必要的工具来查询该数据库并将其向公众开放。实验室的测量值是连续收集的，因此数据库正在持续进行中。物理属性的空间分布可以使用简单的GIS工具可视化为地图。这里以室温下的体积密度和速度分布作为数据表示的例子。详细描述了生成这些地图的方法。此外，我们还提供了使用特定数据集的示例，可以使用其压力和温度导数来开发地壳模型。
