Adding value to digitizing with GIS

Abstract

Purpose

The purpose of this paper is to present a project that digitized the 1906 Soil Survey of Tippecanoe County, Indiana, extracted its contents into full‐text and geospatial datasets, and then built them into a web application designed to approximate but improve upon the way soil surveys are typically used by soil scientists in their research and field work.

Design/methodology/approach

The components of a 1906 soil survey document were scanned and their contents were extracted using several different methods, chief among them imagery segmentation and classification. The resulting datasets included a full‐text version of the original narrative and two georeferenced versions of the soil survey map.

Findings

Going several steps beyond just scanning, including the application of geographic information system (GIS) capabilities, adds significant value to geospatial materials whose contents are still relevant but whose formats are cumbersome. In addition, this allows for a GIS platform to which other maps and content can be added.

Originality/value

This is a unique approach to enhancing content through GIS.
