Xiaoheyan Occupation

Detailed data are provided for all the collection units in which Xiaoheyan ceramics were recovered, together with the Xiaoheyan surface sherd densities in all those collection units. The details of grouping of collection units into local communities are also provided. No supra-local communities (or districts) were in evidence for Xiaoheyan times, so there are no maps delineating them.

The basic data map is provided in a vector format and two raster formats.

In vector format, there is an AutoCAD (Release 12) .DXF file called XHY.DXF. Each collection unit that yielded Xiaoheyan sherds is indicated by an AutoCAD closed polyline on the layer LOTS (color Magenta) enclosing its complete area. The Xiaoheyan surface sherd density (sherds per square meter) is attached to the polyine for each collection unit as its z-value (that is, its elevation).

In raster format, cell values are Xiaoheyan sherd densities (in sherds per square meter). The Idrisi raster layers are in XHY-IDRISI.ZIP (a compressed file that contains XHY.RDC and XHY.RST).

Details of the grouping of collection units into local communities in the published analysis are provided in the form of an AutoCAD (Release 12) .DXF file. This file has a single layer, CLUSTERS (color Magenta), which contains closed polylines encircling the locations of non-contiguous collection units that were grouped together as local communities. Non-contiguous collection units not falling within one of these polyines were each treated as a separate local community. Click here to download the file XHY-LOCAL.DXF (28 KB).

Since no supra-local communities (or districts) were in evidence in Xiaoheyan times, there is no map to delineate them.
