Survey & Documentation: Pixels, Clouds, Points, and Beyond

Preservation has benefitted recently from advances in data collection technology, and new tools are being used to evaluate and document our built heritage at breakneck speed. Drones, Laser Scanners, Virtual Reality, and Photogrammetry have enabled practitioners to more effectively document existing building conditions.

At the same time, the preservation practice relies on the time-tested value of large format photography, measured drawings, and ‘boots-on-the-ground’ field collection techniques that have stood the test of time and remain as valued components of any project.

Survey work is also benefitting from advances in technology, including the landmark multi-year SurveyLA effort. Professionals for the field survey side will discuss the benefits, costs, and ins and outs of field survey methods and tools.

Topics with case studies include:

Session 1: “Get to the Point!”: An Overview of Building Data Collection Techniques

  • The why and how of data collection and its utility for owners, developers, and other end-users
  • A brief look at laser scans, drones and Gigapan photography

Session 2: A HABS/HALS Guide to Field Documentation – Experts’ Overview

  • Sketching, Photography, and Measured Drawings
  • Techniques to increase efficient data collection
  • Techniques for Landscape Documentation

Session 3: Large-scale and Thematic Survey Work – Techniques from the Pros

  • Windshield surveys and using technology in the field for data collection
  • Techniques and templates – tools used by the surveyors both in and out of the field.
  • Using publicly available and other low-cost tools for data collection or management
