Mar 20, 2015. EXPLORING PALEOICHNOLOGICAL AND NEOICHNOLOGICAL APPLICATIONS OF THE FREE DIGITAL CAPTURE SOFTWARE AUTODESK 123D. Uses photogrammetry to create 3D digital models from still photographs taken either with the camera built into the mobile device running the application. Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex (rex meaning 'king' in Latin), is one of the most well-represented of.

Autodesk 123D Catch is freely available for PC, iPhone, iPad, Android, and as a web-based application. The software uses photogrammetry to create 3D digital models from still photographs taken either with the camera built into the mobile device running the application or with a digital camera and uploaded through the website. Ichnological applications of digital models include quantifying such difficult-to-measure properties as volume and surface area, visualization of complex 3D architectures, preservation, teaching, and outreach. My goal is to explore 123D Catch 3D model resolutions and fidelities using different digital capture methods. Captured models range in size from mm-scale trace fossils on bedding planes to entire outcrops.

Scanned traces include examples of Treptichnus, Arenicolites longistriatus, and Attenosaurus from the Pennsylvanian Pottsville Formation, Steven C. Minkin Paleozoic Footprint Site, Walker County, Alabama, Gyrolithes from the Eocene Tallahatta Formation, Grenada County, Mississippi, casts of theropod dinosaur footprints (cf. Eubrontes) from the Cretaceous De Queen Formation, Howard County, Arkansas, and plaster casts of modern armadillo foraging pits from soils in Lafayette County, Mississippi. Preliminary results show a wide range in model resolutions (measured as mesh vertices/cm 2).

Distance from the subject during photography plays a large role in determining the final resolution of the 3D model. The highest resolution produced so far is 459 vertices/cm 2; this is an order of magnitude lower than the resolution typical of models produced with the relatively inexpensive NextEngine laser scanner.

The resolution of the 123D Catch models is suitable for capturing overall architectures and geometries. In some examples, models captured with an iPhone were higher resolution than models photographed with a high-quality digital SLR camera. Scale is not preserved in 123D Catch digital models so all imagery must include scale bars and resizing is necessary with post-processing software, e.g., Blender. Such small-scale features as a ~1 mm diameter Treptichnus and the surficial striations of A. Longistriatus were too fine to be captured.

Finally, highly contrasting colors on the flat surface of a scale bar can introduce artificial topography (. © Copyright 2015 The Geological Society of America (GSA), all rights reserved.

[This is Table 1 at the Digital Geology Express session—a blend of workshop and digital poster. Free participant sign-up at www.digitalplanet.org/site/Events. Participants get a seat at each table and hands-on interaction.] The modern world of iPhones, iPads, Android devices, and apps of all varieties has transformed how we access and process information in the field. This has profound consequences for field geoscientists, as techniques and methods for data acquisition and mapping in the field have been dramatically advanced and simplified by these new tools.

At this digital poster station we will discuss new devices and apps for geologic fieldwork and demonstrate example workflows. The Sims 2 Expansions Torrent Download there. Examples include iPads running the iGIS and GeoFieldBook apps, Open Data Kit for Android devices, and an app implementation of the Open source GIS program Quantum GIS on various platforms. These applications expand the capabilities of field data acquisition to virtually any mobile platform and largely supplant traditional paper maps and hardback field books. A particularly useful digital tool for field geologists is GeoFieldBook, an iOS and Android based app that can be used to collect structural and other field observations. Records log location and date information, orientation measurements, formation names, text observations and photos taken with the tablet camera. Records are customizable, so users can add fields of their own choosing. Data are displayed on an image base in real time with oriented structural symbols.

The image base can also be used for in-field navigation, replacing paper field maps. All data can be exported to a.csv file for use in other analysis applications. For many geologists the only traditional tools that remain in their field kit are a hand lens and compass, and some would argue that even the venerable Brunton compass’s days are numbered!

For example, most smart phones and tablets now contain magnetometers and accelerometers and several apps use these sensors to make routine measurement of orientations of planes, lines, or both in a single measurement. Nonetheless, the underlying inexpensive hardware in these devices is highly variable, and work is needed to determine the precision and variances among devices before they should be routinely used for geologic measurements.
