Map of Carolingian Coin Hoards (AD 751-987) in OpenWebGIS
openwebgis

Information of Carolingian Coin Hoards was taken from The Digital Atlas of Roman and Medieval Civilization (DARMC).

Abstract: "This geodatabase is a digital edition of the data provided in Simon Coupland's 2011 "A Checklist of Carolingian Coin Hoards 751-987," which gives a comprehensive summary description of hoards containing more than three coins issued by the Carolingian dynasty and found in Europe up to the date of publication. DARMC contributors have expanded Dr. Coupland's work by adding geographic coordinates to hoard findspots and coding numeric fields to facilitate the spatial and quantitative analysis of this data. This dataset is not exhaustive of the information from Coupland 2011 and careful attention should be paid to the additional notes in the original study."

3. Then click on the point you are interested in and you must get the result like in Figure 4. The values of all attributes of each hoard you can see by hovering the cursor over it and clicking on it (if while hovering over a polygon, it is not activated, then move the map a little bit and then again hover the cursor).
