Testing and Validating the Suitability of Geospatially Informed Proxies on Land Tenure in North Korea for Korean (Re-)Unification

Abstract

The role of remote sensing data in detecting, estimating, and monitoring socioeconomic status (SES) such as quality of life dimensions and sustainable development prospects has received increased attention. Geospatial data has emerged as powerful source of information for enabling both socio-technical assessment and socio-legal analysis in land administration domain. In the context of Korean (re-)unification, there is a notable paucity of evidence how to identify unknowns in North Korea. The main challenge is the lack of complete and adequate information when it comes to clarifying unknown land tenure relations and land governance arrangements. Deriving informative land tenure relations from geospatial data in line with socio-economic land attributes is currently the most innovative approach. In-close and in-depth investigations of validating the suitability of a set of geospatially informed proxies combining multiple values were taken into consideration, as were the forms of knowledge co-production. Thus, the primary aim is to provide empirical evidence of whether proposed proxies are scientifically valid, policy-relevant, and socially robust. We revealed differences in the distributions of agreements relating to land ownership and land transfer rights identification among scientists, bureaucrats, and stakeholders. Moreover, we were able to measure intrinsic, contextual, representational, and accessibility attributes of information quality regarding the associations between earth observation (EO) data and land tenure relations in North Korea from a number of different viewpoints. This paper offers valuable insights into new techniques for validating suitability of EO data proxies in the land administration domain off the reliance on conventional practices formed and customized to the specific artefacts and guidelines of the remote sensing community.

Polynuclearity as a Spatial Measure of Urban Sprawl: Testing the Percentiles Approach

“…The adaptation of the method of Galster et al [9,10] to Polish conditions necessitates caution in evaluating the results obtained. Therefore, the complementary use of the measures allowed for a triple verification of nuclearity and is consistent with the assumed validation approach to the performed studies [60][61][62][63].…”

“…The task of validation is [60,61]: to identify possible errors and correct them; to compare methods quantitatively; to provide reliable information to make informed decisions. The literature on validation of space morphology tests addresses the issue of accuracy of test results [62,63]. The methodological approach of taking test samples and further analyzing them is an important part of accuracy assessment [60].…”

“…The methodological approach of taking test samples and further analyzing them is an important part of accuracy assessment [60]. There are several techniques for validating a study of data accuracy or error [63]: visual inspection, non-site-specific analysis, difference image generation, error budgeting, and quantitative accuracy assessment.…”
