The French Ministry of Culture has made part of their database of historical monuments, Base Mérimée - monuments historiques, publically available to use under an Open Licence. The dataset can be obtained from the website data.gouv.fr in CSV-format. To increase the density of archaeological information in Regnum Francorum Online (RFO), a subset of the base Mérimée dataset has been integrated into

The Regnum Francorum Online (RFO) historical GIS does not exclusively concern the Merovingian and Carolingian Frankish kingdom, but also the Roman foundation on which the Early Medieval civilisations was built. To put some light on this, and describe the Late Roman empire, two layers are part of the GIS. Both layers are based on primary sources. The first layer is a compilation of Roman

In this post I will demonstrate what can be achieved regarding knowledge of Ancient history by compiling persistant identifiers of several external resources. The coordination of sources, and hence the advantage of having them displayed together, is accomplished through the use of a common geographical interface, where layers of one or more external sources could be displayed.The Regnum Francorum

Historical source-documents are increasingly becoming available on the Internet. It's a huge resource waiting to be elaborated. The sources often come in one of two formats. They are published as graphical scans of printed book pages with or without large chunks of unedited OCR-text, or they can be fully formatted as an electronic text, that can be copied, edited or searched. Often little or no

The historical GIS application Regnum Francorum Online references historical events in time, space and by agency and link the events to source documents and literature available online. In doing so, the application becomes a GIS-interface to a growing number of both primary and secondary sources online. This also includes the huge collection of articles in the Wikipedia. To me, it has become

In an earlier post I showed how to store and retrieve spatial POINT geometries in MySQL and PHP. A POINT is a geometry that represents a single location in coordinate space. In this post we will be dealing with more complex spatial data such as LINESTRING and POLYGON, in real world representing for example rivers, roads, or territories in coordinate space. A number of Shapefiles (SHP) describing

This post describes some aspects of using MySQL spatial extensions in the historical GIS application Regnum Francorum Online. Because I was already using MySQL to store evidence of historical events, the choise to try out the spatial extensions of MySQL that were introduced in version 4 was very close at hand. The geographical information system Regnum Francorum Online (RFO) is a MySQL database

Regnum Francorum Online — interactive maps and sources of early medieval Europe 614-840 is a historical geographic information system (GIS), aiming at referencing historical events of Merovingian and Carolingian Europe (Frankish kingdom) in time and space. The information system covers the time period approx. 614 to 840. Historical events are recognized through source-documents of different kind,
