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.

The necessity of solving a number of methodological tasks is substantiated, aimed at ensuring the objectivity of estimating the visual, measuring and information quality of materials for remote sensing the Earth on the basis of test sites. The results of generalization of the accumulated practical work experience on creating test sections, which are formalized as a methodological approach to creating a priori data base for assessing the space survey materials quality, are presented. As part of the proposed methodological approach to arranging a priori data base for assessing the Earth remote sensing materials quality, a set of issues related to the requirements for selecting test sites, sampling and justification of test objects at sites, determining the characteristics of these objects, the content of the test site, requirements to the site passport and passports of test objects, to the content of the database in the form of a geoinformation system of the test site is reflected. The urgency of developing a network of test sites for control, calibration and estimating the quality of the obtained materials from space survey systems, the main elements of which are typical objects of natural and anthropogenic origin, is substantiated. A set of issues related to maintaining the test sites up-to-date is considered.

Indonesian National Institute of Aeronautics and Space (LAPAN) as a space ecosystem runner government institution of the space agency in Indonesia is mandated by Indonesia space law of 2013 to carry out remote sensing activities that are not only strategic nationally in nature but also charged being benefits economically. This study investigated the intangible economic benefits of remote sensing activities in Indonesia. This research explored qualitatively the advantage of the use of remote sensing information by users obtained from the results of questionnaires and in-depth interviews. The conceptual framework of intangible benefit is based on the information system success model by the De-Lone and McLean Information Value model. The results showed that the quality of remote sensing was good. This can be seen from most responses of user respondents on the Perceived System Quality and Information Quality indicators giving a good rating. The response of the user respondents caused a sense of satisfaction and also caused the use of the system to be more intense. These had a good impact on the performance of respondents, both individually and organizationally. Strengthened by in-depth interviews showed that economically provide benefits with an average of 64% increasing in the efficiency of the performance by Agriculture and Palm Oil sectors. In short, space agency in Indonesia is proven to provide intangible economic benefits on remote sensing activities.
