“…The cartographic uncertainty, while useful for conflation and integration purposes, will typically be minor compared with non-GPS based geographic uncertainties (Clegg et al, 2006;Whitmeyer, Nicoletti, & De Paor, 2010), particularly when field notes are not associated with the metadata, and the measuring and interpretive geological uncertainties.…”

Old, archived geologic maps are often available with little or no associated metadata. This creates special problems in terms of extracting their data to use with a modern database. This research focuses on some problems and uncertainties associated with conflating older geologic maps in regions where modern geologic maps are, as yet, non-existent as well as vertically integrating the conflated maps with layers of modern GIS data (in this case, The National Map of the U.S. Geological Survey). Ste. Genevieve County, Missouri was chosen as the test area. It is covered by six archived geologic maps constructed in the years between 1928 and 1994. Conflating these maps results in a map that is internally consistent with these six maps, is digitally integrated with hydrography, elevation and orthoimagery data, and has a 95% confidence interval useful for further data set integration.

“…Due to improvements in computer technology, traditional geological maps can be processed using digital procedures (Whitmeyer et al 2010;de Donatis et al 2012). Because of the need to measure geological elements, such as bedding plane and formation boundary in the field, the procedures use only indirect digitization methods, which convert field data from such geological elements into digital formats.…”

Traditional geological mapping may be hindered by rough terrain and dense vegetation resulting in obscured geological details. The advent of airborne Light Detection and Ranging (LiDAR) provides a very precise three-dimensional (3D) digital terrain model (DTM). However, its full potential in complementing traditional geological mapping remains to be explored using 3D rendering techniques. This study uses two types of 3D images which differ in imaging principles to further explore the finer details of sedimentary terrain. Our purposes are to demonstrate detailed geological mapping with 3D rendering techniques, to generate LiDAR-derived 3D strata boundaries that are advantageous in generating 2D geological maps and cross sections, and to develop a new practice in deriving the strike and dip of bedding with LiDAR data using an example from the north bank of the Keelung River in northern Taiwan. We propose a geological mapping practice that improves efficiency and meets a high-precision mapping standard with up to 2 m resolution using airborne LiDAR data. Through field verification and assessment, LiDAR data manipulation with relevant 3D visualization is shown to be an effective approach in improving the details of existing geological maps, specifically in sedimentary terrain.

“…A variety of approaches have been described in the literature including in-field GIS approaches emphasizing 3D recording with complex stratigraphy (Katsianis et al 2008), use of a GIS on a laptop or tablet together with orthorectification software (Craig 2000;Craig et al 2006;Doneus and Neubauer 2004), commercial software dedicated to interfacing with a total station on a pocket PC or tablet PC (Bradley 2006;Levy and Smith 2007;Ziebart et al 2002), and customized database software written for handheld computers (Skousen 2004;Tasic and Jevremovic 2004;Powlesland 2010: 104). Archaeological applications also benefit from advances in digital field methods in related disciplines like field geology (Apel 2006;Whitmeyer and Nicoletti 2010).…”

Archaeologists have embraced new technologies in many aspects of research, but reliance on paperbased recording has impeded development of excavation recording methods. The digital recording of spatial provenience for artifacts and features, together with complex attributes during excavation, while not problem-free, provides a streamlined recording process. This article describes a digital interface that links precise spatial provenience with digital forms and geo-referenced photographs during excavation at a colonial site in highland Peru. A customized version of ESRI ArcPad provides the means to create and to explore spatial and attribute data in the field and laboratory as GIS data, which in turn can be integrated with ArcGIS for post-field visualization and analysis.
