Loosening the grid: topology as the basis for a more inclusive GIS

Abstract

The past 25 years have seen a proliferation of interest in GIS among humanists and humanistic social scientists. Under various bannershistorical GIS, qualitative and mixed methods GIS, spatial and digital history, digital humanities, spatial humanities or geohumanitiesresearchers have developed new ways to include qualitative data within the framework of GIS. At the same time, social and theoretical critiques of GIS as a tool wielded chiefly by and for those in power have increased awareness of its limitations, particularly for studying human perceptions, experiences, and the meanings of place. We agree with a growing chorus of geographers that the most common data structures in GIS are inadequate to capture or analyze the relational dimensions of subjectivity. As part of the solution, we propose an alternative hybrid framework that prioritizes topological relationships while retaining coordinate locations as points of connection between geographic places and experiential evidence. This article explains how the challenges posed by Holocaust survivor testimony inspired us to pursue inductive spatial analysis and non-coordinate means of mapping. We then set out a model for a topological GIS and illustrate its application with two survivor testimonies and a map of their experiences.

A Fast Detection Algorithm for Change Detection in National Forestland “One Map” Based on NLNE Quad-Tree

“…On this basis, superimposed multi-source data such as topographic maps and remote sensing images achieved a breakthrough in the management of China's forest resources [4][5][6][7]. They provided a unified national base map for forestry scientific research, daily resource management and forestry development planning for the first time [1,[8][9][10].…”

Relational Reprojection Platform: Non-linear distance transformations of spatial data in R

“…Ultimately, in our quest for better visualization of what Pip Forer (1978) calls “plastic” and relational spaces, we built a tool to fit our own needs. Relational Reprojection Platform is one of multiple parallel attempts to expand the visual vernacular with which we approach non-Cartesian data (for irregular grids, see Lally, 2022; for mapping with limited coordinate access, see Westerveld and Knowles, 2020).…”
