Digital Field Recording in the 4th Dimension: ArchField C++ and OpenDig
Neil Smith and Matthew Vincent

This tutorial will provide the key software tools to enable any archaeologist to begin integrating digitial field recording methodologies into their excavations. It will focus on helping the attendants install, setup, and use ArchField C++ and OpenDig along with discussing pertinent approaches the presenters are taking to conduct terrestrial and aerial photogrammetry and other new advanced techniques in field recording. ArchField C++ is the latest version of our digital field recording software that enables real-time digital GIS Top Plan production within a rendering engine designed for visualizing massive 3D datasets. ArchField directly connects to Total Stations and our RTK GPS units to record sub-centimeter measurements for artifacts, scanning markers, loci boundaries, and camera positions. The processing pipeline enables the generation of publishable orthographic and perspective maps from the first day of excavation to the last. As a backend it uses a PostGIS and CouchDB database and the ability to export and import various vector, raster, DEM and 3D datasets. OpenDig is a platform for recording, editing, managing and publishing archaeological field data collected in the field. Through CouchDB, Apache's NoSQL database, OpenDig is able to adopt a flexible data structure which can be easily modified to fit any particular project, whether it is excavation, survey or other cultural heritage management systems. OpenDig is the digital version of the Madaba Plains Field recording methodology and is a powerful tool for any supervisor seeking to document their area’s excavation.

The tutorial will be divided into four main sections with an expected duration of one hour. Since our software is provided freely there will not be any tutorial costs related to this submission.

Outline
  1. Introductions and Sharing of Current Methodologies (20 min.): In this section we will introduce ourselves and give the attendants a background to our +15 years digital field experience in Jordan. We will describe in detail how digital field recording is conducted in our region, its evolutionary history and specific methodologies we have adopted over this period and integrated as core features in the software that we believe are universal. We will then introduce our current software and highlight its potential uses. (During this time attendants will be passing around several usb disks and copying the files to their computers).
  2. Installation and Setup of ArchField and OpenDig (10 min.): This section will be devoted to assisting attendants in installation and setup. The distributed digital folder will include instructions, test datasets, related published works and the software.
  3. Mock Digital Field Excavation Exercise (15 min.): We will conduct a mock run through of a field excavation with the attendants allowing them to test out the software and become familiar with it.
  4. Assessment and Take-Away (15 min.): The mock trials will be assessed by the presenters and the attendants. This time will primarily be open for attendants to discuss specifics of their digital field recording needs with the presenters and how the software may need to be adapted to fully suit them. The authors will address more technical aspects of the software and also discuss their current development pipeline including future directions. Given time permitting, we will discuss how we are integrating SfM recording into our field recording pipeline and how we plan to converge the technologies together.
