Case study: Using GIS Cloud for archaeological field data collection

We did an interview with Dr. Gugl from the Institute for the Study of Ancient Culture in Austria. They have been using GIS Cloud in their research of Roman Military Camp – Municipium – Late Antique and Byzantine Fortification.


GIS Cloud: Can you tell us some basic information about the project you are doing and why was there a need for a cloud GIS based solution?

Dr. Gugl: Troesmis is the name of a Roman and Byzantine city on the lower Danube, nowadays situated in Romania close to the modern city of Tulcea. In 2011, the Austrian Academy of Sciences started an archaeological field project in close cooperation with the Archaeological Institute of the Romanian Academy of Sciences. Another project partner is represented by the Institute of Archaeology of the University of Innsbruck (Austria). The involved project partners perform different tasks on this huge archaeological site which is one of the largest archaeological settlements in Romania, including a Roman legionary fortress (2nd century AD), a Roman town (2nd/3rd century AD) and two other fortifications dating from the 4th to the 13th century AD.

In the last years different kinds of information were collected by the project partners: air photo and satellite photo interpretation, airborne laser scanning, geophysical prospection, archaeological field surveys and the documentation of archaeological traces, still visible on the site, using CAD-software and photogrammetry.


What were some of the challenges that your project had and that you overcame with GIS Cloud apps?

In the Troesmis project, usually different teams were working on the site with the need of an easy usable, GIS based technology to do the documentation work. Especially the mapping of archaeological findings in an area of approximately 35 km² by a survey technique called line walking (4 to 6 archaeologists arranged in a line were walking over the accessible fields) is an ambitious task. With the help of GPS and GIS technology in combination with a cloud based solution this could be organized much more efficiently.



Can you describe us your project workflow once you deployed GC apps?

GIS Cloud apps are easy to use. Most people are familiar with smart phones and within a short time, they can handle the device. The data collection app provides an elaborated functionality, so that each team had a mapping device in their hands. Consequently, if you can accept a mapping accuracy of 5-10 m, there was no need of expensive GIS field computers. It is possible to provide both base maps and vector data to the different teams which are essential for evaluating archaeological features on the ground. In an open scenery like in Troesmis where you are facing a steppe-like landscape, it is important to determine your own position in relation to known archaeological features, for instance crop marks which are mostly not visible from the ground. This additional information is made available via the GIS Cloud, which is extremely helpful if you intend to map new features or artefacts.


Even in a rural landscape like in this part of Romania, where you are in between the meandering watercourse of the Danube and the slopes of the Măcin Mountains, data acquisition via the internet worked surprisingly well. The GSM network coverage is mostly sufficient and even if you are moving in a remote area, we had no problems because of the buffer storage of the devices.


What would be 3 key features in your opinion that you would recommend GIS Cloud for coming from Archaeology perspective?

  • The possibility to provide different teams with the same easy to use mapping tools
  • Easy to use mapping tools on smart phones have a positive effect on enrollment costs
  • General advantages on web based GIS technology (availability of the same data sets, …)

Facebook’s Place Tips: Now available to any business in USA

Facebook Place Tips - GeoawesomenessPLACE TIPS

Place Tips is basically Facebook’s Location Based Notification application that runs inside the Facebook app that will push notifications to your smartphone when you are near a particular store. So if you are window-shopping in front of an electronics retailer, which happens to have Facebook’s Bluetooth beacon installed, then chances are that you’ll get a notification with information (and maybe, offers) to your smartphone automatically. All you need to do, is have the Facebook app installed on your device.

(Related: Facebook’s gets more location-aware with Place Tips and iBeacons).

Now Available Across United States of America

Facebook initially rolled out Place Tips to a few select retailers in New York at the beginning of this year. According to Engadget, it is now available to any business in America and if you are a business owner, you could request a free beacon for your company, using their web page.
