COMPARATIVE HEADSTONE ANALYSIS AND PHOTOGRAMMETRY OF CEMETERIES IN ORANGE COUNTY, FLORIDA.
Title
COMPARATIVE HEADSTONE ANALYSIS AND PHOTOGRAMMETRY OF CEMETERIES IN ORANGE COUNTY, FLORIDA.
Creator
Robinson, Tyra, Schultz, John, University of Central Florida
Abstract / Description
Headstones manifest an abundance of historic information and embody society's cultural and socioeconomic statuses over time. Cemetery research has been conducted throughout various regions in the United States, but very little has been focused on headstone analysis in the state of Florida. The purpose of this comparative research is to use a typology established by Meyers and Schultz to compare headstone attributes of Orange County, FL and establish a temporal correlation (2012).

Show moreHeadstones manifest an abundance of historic information and embody society's cultural and socioeconomic statuses over time. Cemetery research has been conducted throughout various regions in the United States, but very little has been focused on headstone analysis in the state of Florida. The purpose of this comparative research is to use a typology established by Meyers and Schultz to compare headstone attributes of Orange County, FL and establish a temporal correlation (2012). The analysis of this study has the ability to highlight societal perceptions and ideals surrounding death and mortuary practices while providing a historical context specific to the state of Florida. Data was collected from two cemeteries in Orange County, representing the headstones of 853 individuals. The methodology of this study entailed visiting the cemeteries, photographing headstones, and noting headstone attributes. Following the model set forth in Meyers and Schultz, attributes taken into consideration for this project were stone type, shape, time period, and sex of the individual (2012). In addition to assessing headstone typology for historic cemeteries, the development of best practices for photogrammetry of headstones will be examined. The questions addressed in this research will hopefully illuminate mortuary trends in Central Florida and encourage future research and literature to shift its focus to include southern regions of the United States in terms of historical Cemetery context. Additionally, practices developed in photogrammetry can aid public archaeology conservation and restoration efforts of historic cemeteries that are endangered of being lost due to external circumstances.

Testing the Capability of Close-Range Photogrammetry to Document Outdoor Forensic Scenes With Skeletal Remains Using Mock Scenarios

Testing the Capability of Close-Range Photogrammetry to Document Outdoor Forensic Scenes With Skeletal Remains Using Mock Scenarios.

Abstract / Description
More rigorous methodological protocols are needed to document outdoor forensic scenes containing skeletal remains. However, law enforcement protocols rarely provide specific guidelines for processing these scenes. Regardless, the need to preserve contextual information at crime scenes is of paramount importance and it is worth exploring new technological applications that will allow for better documentation.

Show moreMore rigorous methodological protocols are needed to document outdoor forensic scenes containing skeletal remains. However, law enforcement protocols rarely provide specific guidelines for processing these scenes. Regardless, the need to preserve contextual information at crime scenes is of paramount importance and it is worth exploring new technological applications that will allow for better documentation. Close-range photogrammetry (CRP) is one option for outdoor scene documentation, more prominently utilized in archaeological contexts, that may provide forensic archaeologists with a tool to better document these scenarios via 3D modeling. To test the efficacy of CRP as documentation tool three mock scenarios representing common outdoor scenes were created using faux osteological material: a close scatter of osteological remains in a pine flatwood setting, a wide scatter of osteological remains in the same setting, and the partial excavation of skeletonized remains. Images were collected using a digital camera and processed using Agisoft Photoscan Professional. A series of variables were tested in successive iterations of data capture for each scenario to determine best practices for overall accuracy: camera images captured by hand versus fixed to a tripod, scale bar positioning, and number of images captured. Accuracy was determined via final root mean square error values and through a comparison between real-world to virtual measurements. Results show that CRP is a cost and time-effective method of documenting contextual data at a scene via the creation of 3D models and scaled orthomosaic images. This method is most useful for the documentation of excavations owing to the controlled and contrasted sub-surface in comparison to the subject material. The two scatter scenarios offered additional challenges due to the complexity of the ground covering, however models nonetheless provided accurate contextual detail and errors may be mitigated through proper data capture. There was little difference in the variables for image capture, scale bar placement, or number of images. Instead, the quality of images, image capture method, and post-processing operations proved to be more important. Due to the ease of use and the ability to convey best practices for data capture, the utilization of CRP for outdoor scene documentation is recommended as a valuable addition to current forensic documentation protocols. Future research should focus on the utilization of actual osteological material as a proxy for forensic scenarios as well as study the applicability of CRP to assist in documenting taphonomic modifications.

Show moreWhile it is true that historic cemeteries are places that contain a wealth of knowledge about the history of a community they are sometimes not well maintained. The information within can be lost as grave-markers are damaged either by natural causes or human interaction. In larger cemeteries preserving these significant places can sometimes be difficult due to a number of different factors. Therefore focusing preservation efforts on specific locations where damage is more likely to occur is crucial to ensure that the monuments that are the most at risk are preserved. One possible way of accomplishing this is through the utilization of a geographic information system (GIS) to determine the shortest distance path an individual may take to reach a specific grave-marker. This can be accomplished by conducting a near analysis between an origin point and every grave-marker. These paths would also show each grave-marker that an individual passes indicating the potential for purposeful or accidental interaction. With this information efforts such as photogrammetry can be applied effectively for digital heritage preservation. Such methods would permit individuals to manipulate three-dimensional representations of grave-markers in order to preserve a large portion of the information it contains.
