**2. The ArchaeoKM project**

This chapter begins with a discussion about a general overview of the industrial archaeology. It presents the case study of the research site by discussing the nature of the

closely related to the activities of steel production in Krupp. The site grew over the decades and formed a so-called Krupp Belt. The site was destroyed during the Second World War. Most of the area is never rebuilt. In between 1945 to 2007, the area was basically a wasteland making it an ideal site for an industrial archaeological excavation. However, the ThyssenKrupp is returning to build its new headquarters in the site by then 2010. This has raised the problem of limitation of time period for a proper management of the recovered objects. The objects are recorded as soon as they are recovered and these records are stored in a repository in their respective data formats. Hence, there is a clear lack of well-defined structure for data management. Moreover, in contrast to the conventional archaeology where the data collection and data analysis goes side by side so in that case the data structure could be designed at the beginning, the data analysis is carried out at the end in industrial archaeology so it is not possible to perceive the structure of the data at the beginning. The first challenge consists of creating a proper data structure which helps in retrieving those data efficiently. As there was not enough time to filter the collected data concurrently, the amount of data that are collected is huge. Hence, the system that has to

Archaeologists with assistance of photogrammetric specialists were involved in data acquisition process. They were responsible to decide the methods of measurements. The findings were scanned through terrestrial laser scanning instruments. Two scanners were used to acquire the scanned data. They were the Zöller and Fröhlich scanner (ZF) and the Riegl scanner. Those two scanners were used according to their requirement. Large objects scanning were carried out with the help of the Riegl scanner whereas the ZF scanner is used whenever some important findings are recovered. The Riegl scanner was installed on the roof of the Kreuzhaus (the building marked at the bottom of the site in figure 1) so that the scanner gets a good overview of the area. The findings were scanned with a resolution of 0.036 degrees (6 mm on 10 m) hence the point cloud is very dense. All the data were stored

An orthophoto was orthorectified from the aerial images (that were taken during the course of research work). The orthophoto has 10 cm resolution and is in GK II coordinate system. Huge numbers of digital pictures were taken during the research activities and they were stored in their original formats. These photos were taken with non-calibrated digital cameras. However, certain knowledge can be extracted from them by the archaeologists. Besides, photographs documents like the site plan of the area and some documents with relevant information of the site or the objects recovered were collected during data acquisition process. These data and documents were digitized and stored for proper mapping with the relevant objects. Archaeological notes taken by archaeologists during these excavation processes are of high importance. Hence, these notes are digitized and stored in the repository. Similarly, the site plan of the area was digitized and stored as .shp

The nature of the dataset that was collected during the research work is varied. There are four distinct kinds of data which ranges from textual documents as the archaeological notes to multimedia documents as images. The heterogeneity of dataset is evident through the nature of each type of dataset varying completely from others in terms of their storages,

data collected during the excavation process. It then reviews the current Information Systems that are either being implemented or researched in this domain. It includes the usages of Geographic Information Systems (GIS) in this field. Then after, the chapter continues with the introduction of the ArchaeoKM project through discussion on the principle and how it is different from the existing systems. It concludes with a discussion on the future prospective of the work.
