The archaeology of Saudi Arabia
Saudi Arabia covers 2.15 million sq km – twice the size of the UK, France and Germany together. On the other hand, it is one of the least explored countries archaeologically. In 1976, a Comprehensive Archaeological Survey Program (CASP) was initiated and from 1977 to 1982 the newly established journal Atlal carried a spate of large interim reports from fieldwork in the Saudi provinces (Adams et al., 1977, Gilmore et al., 1982, Ingraham et al., 1981, Parr et al., 1978, Potts et al., 1978, Whalen
Remote sensing in Saudi Arabia – from aerial photographs to satellite imagery
The CASP teams had virtually no access to aerial imagery; only one (Zarins et al., 1979: Plate 7) of the nine interim reports included a single aerial photograph. Even when aerial photos were available they were of a very small scale and virtually useless (Adams et al., 1977: 24, 32; cf. Parr et al., 1978: 29). Plainly this was a serious drawback and other teams stressed that aerial imagery was the essential key to large-scale mapping in the future (Adams et al., 1977: 25, 36; Ingraham et al.,
Methodology: Jeddah2 window
A number of areas within Saudi Arabia have been explored by the first author through high-resolution ‘windows’ on GE and Points of Interest (POIs) ‘pinned’. One of these windows, Jeddah2, was chosen for the purposes of the present evaluation and the second author undertook to examine the relevant POIs in more detail. The study area comprised a strip 17 km by 72.8 km, a total of c. 1240 km2 (Fig. 1). This area was originally dictated by the then-available high-resolution imagery (which has
Interpretation
Measurement within GE is problematic as it is difficult to calibrate the built-in measuring tool in a remote region. Moreover, the results are presented with what might be viewed as a spurious and deceptive accuracy. Thus the displayed measurement of the east to west diameter of, say, Cairn 38 as 9.3497 m is misleading. Although the satellite images are of sub-metre resolution (with evident interpolation in the presentation of the image for the screen), they cannot support that level of
Analysis
Although the number and variety of site types in this single Jeddah2 window is impressive, a general familiarity with other areas of Arabia immediately raises a question: What is absent? The lava terrain of Jeddah2 is similar to that elsewhere from the Syro-Jordanian Harrat ash-Sham to the Harrat al-Brk in the south-west and the stone structures in each are recognizably of the same character. Yet important types are missing or only present in quite different forms. The most obvious missing
Conclusion … and future
The ‘Jeddah window’ has provided an opportunity to explore one area in far greater detail than ever previously possible. More importantly it has been a test-bed for methodology. Even for this single window the range of types of ancient stone structures is considerable and presented challenges in cataloguing. That has been made sharper by the knowledge – albeit less detailed – of variant site types in other windows and even further types which will ultimately require an Arabia-wide typology to

2021, Journal of Cultural HeritageCitation Excerpt :The conventional methods applied to record these cultural heritage sites have been pedestrian surveying, aerial photography analysis, metal detecting, geophysical surveys and, recently, LiDAR data [4,7–14]. Aerial photographs have been obtained with the use of light aeroplanes [15], balloons [8] or satellite images in platforms like Google Earth [16]. Of all these non-invasive tools, metal detectors have been the most widely-used in the study of battlefield cultural heritage.
Current trauma care system in Saudi Arabia: A scoping literature review
2020, Accident Analysis and PreventionCitation Excerpt :Globally, the burden of trauma is progressively increasing (Hofman et al., 2005) with low or middle-income countries disproportionately affected (Ameratunga et al., 2006). Saudi Arabia (SA) is a large country with a land area of approximately 2,150,000 km2, which is twice the size of the United Kingdom (Kennedy and Bishop, 2011). Although considered globally to be a developing country, SA is one of the highest income countries in the Eastern Mediterranean Region according to the World Health Organization (WHO) (WHO, 2009).
Coastline shift analysis in data deficient regions: Exploiting the high spatio-temporal resolution Sentinel-2 products
2019, CatenaCitation Excerpt :In such cases, the use of alternative approaches such as Google Earth Pro has been shown to be reasonable, see, e.g., Hritz (2013). Google Earth Pro provides high-resolution imagery from several commercial satellites from 2000 to the present, see, e.g., Kennedy and Bishop (2011) and Sadr and Rodier (2012). This study uses Liberia and Somalia as case study regions (see Section 2) and pre-tests Sentinel-2 in Section 3.
