Message #136: From: AzTeC SW Archaeology SIG To: "'Matthias Giessler'" Subject: Rock Images and Landscapes Digital Mapping and Recording Project Date: Wed, 08 May 96 08:06:00 MST Encoding: 128 TEXT From: Jim Ebert firstname.lastname@example.org ROCK IMAGES AND LANDSCAPES DIGITAL MAPPING AND RECORDING PROJECT Under partial funding from the National Science Foundation (Grant No. DMI-9560452), Ebert & Associates, Inc. is conducting a feasibility study focusing on the development of "Rock Art Data Recording, Management and Analysis: An Integrated System Incorporating 3-Dimensional Digitizing, Geographic Information Systems, Photogrammetry and Other Digital Mapping and Imaging Technologies." Ebert & Associates is an Albuquerque, New Mexico firm specializing in archaeological, anthropological, forensic and environmental applications of remote sensing, photogrammetry, image processing, and digital mapping technologies. The Rock Images and Landscapes Digital Mapping and Recording Project is funded by a Phase I Small Business Innovation Research (SBIR) grant from the National Science Foundation. The SBIR program provides for Phase I funding to assess the feasibility of innovative products or processes for an initial 6-month period, following the successful completion of which a proposal for a 2-year, Phase II period of product development is submitted. Rock image (see footnote) studies are currently experiencing increased use of digital technologies, particularly digital imaging techniques. Ebert & Associates' research will build upon such interests, incorporating a wide range of methods and techniques for the "total" recording of rock images and their significantly associated environments and landscapes. Such techniques will include * 3-dimensional digitizing of rock art elements and their minute details, as well as geochemical sample locations, in the field; * the collection of locational data for mapping rock images, rock faces, and details of the terrain a wide range of resolutions and scales using electronic distance measurement (EDM), global positioning systems (GPS), aerial and terrestrial photogrammetry, analog and digital photographic and imaging, and 3-dimensional digitizers; * the integration of all scales of spatial data, as well as associated non-spatial data, in a single spatially-organized database utilizing 2-dimensional and 3-dimensional computer aided design (CAD) and geographic information systems (GIS) technologies; and software developed specifically to facilitate the integration of all stages of the "total system," from in-field 3-dimensional digitizing and other map data collection, through integration and management of the database in CAD and GIS environments, to viewing, statistical analysis, and data output in multiple forms. One critical component of our Phase I feasibility research is to survey the present data needs of rock image researchers, managers, conservators, users and other shareholders, as well as additional needs which could be facilitated by the application of new digital technologies in rock image recording and data management. We would like to ask archaeologists, managers and others whose interests or responsibilities include rock images to participate in this research by answering and returning a short questionnaire, and to communicate any additional information on their needs and suggestions for the development of digital methods and techniques. Rock Images Data Recording Questionnaire Rather than a form with blanks to be filled in, this questionnaire is relatively unstructured, its categories included as suggestions about what respondents might like to include in their answers. Any other, related information is also welcomed. 1) What do you record?? Individual figures Dimensions and measurements (of what?) Panels (what constitutes a panel?) Topography, viewsheds, acoustics, etc. Relationship of figures and panels to surrounding environmental features Relationship of figures and panels to surrounding cultural features or sites Site condition and impacts Management-related data Other data 2) How do you record and manage data? We're especially interested in digital and other innovative techniques you have developed or adapted. Forms (could you send us an example?) Photography (film types, special methods, etc.?) Digital imaging Site maps Panel or figure sketches Tracings Scaled drawings Physical measurements (of what?) Surveying instruments CAD, GIS and other digital mapping methods Do you take samples for dating or other purposes? Video Other recording techniques and methods 3) If you had access to methods for recording 3-dimensional rock image and surrounding landscape data at a wide range of spatial scales, what new applications do you think you would consider in the areas of Analysis and research Site management Site conservation Site condition and impact monitoring Law enforcement and site protection Other new approaches and applications 4) What literature, reports and other descriptions of rock image and landscape data recording, management and analysis should we be aware of in the course of our research (your own articles and reports, as well as those of others)? Please send responses and correspondence to one of the following addresses: Jim Ebert Ebert & Associates, Inc. 3700 Rio Grande Blvd. NW, Suite 3 Albuquerque NM 87107 (505) 344-2345 Fax (505) 344-2444 e-mail: email@example.com
Footnote: The term "rock images" will be used in the course of this research to denote petroglyphs, pictographs, and all of the "rock art" to resolve terminological ambiguity as well as in recognition of the creators, users, and shareholders to whom the concept of these image as "art" is troublesome or incongruous.
