Pen-based mapping - Then and now

Abstract
Over the last few years, a Geographic Information Systems and Information Technology group has developed a process for using pen-based ruggedized PCs for field data collection. The goal is to design simpler, more cost-effective and efficient methods of data collection and processing in the field. The process focuses on creating and verifying data during collection, not in the office.

“Pen-Based Mapping—Then and Now” describes how the group, comprising staff members from Woolpert LLP, a design/engineering firm in Dayton, Ohio, used customizable off-the-shelf software products and pen-based PCs to achieve the goals.

Also discussed, by case history, are the three primary application types targeted: utility management, storm water management, and facilities management. Beginning with the history of pen-based computing, this document traces the rapid progress over just the past few years. Topics include the various hardware and software technologies used to develop these systems, as well as the importance of programmability for creating a seamless process. In addition, the most recent advances pushing the pen-based world into a new generation of systems are reviewed.

Introduction
Significant use of pen-based mapping has only recently become possible. The steps toward developing the process follow a pattern of growth arising from needs and practices discovered during fieldwork-a common path for innovation. What is uncommon is the exponential growth that this development has experienced and will continue to show, and the implications it will continue to have on GIS and other facilities management practices. Pen-based mapping has been clearly demonstrated to effectively accomplish its basic purpose: to eliminate the duplication of effort required to generate accurate CAD records of facilities and their cataloged elements such as utilities, storm drainage, and property layout. The technology overviews and case histories that follow illustrate how pen-based mapping technology has evolved to serve these facilities management practices.
