Evaluating Spatial Data Infrastructure as a Data Source for Land Surveying

Abstract

AbstractImplementation of spatial data infrastructures (SDIs) can maximize access to geographic information (GI) and, through geoportals or other access points, serve as a powerful tool in different fields of practice and specialization. In many countries, the most important sources of infrastructure reference data are survey databases and land information systems managed by surveying and mapping services. However, the SDI frequently has a more interdisciplinary character, which influences the value derived from its use by different communities. This paper aims to present the evaluation criteria of SDI usefulness and usability in the implementation of certain land-surveying tasks. The case study focuses on the Polish SDI (PSDI) and its main access point, Geoportal 2. SDI evaluation considers information and support provided by Geoportal 2, as well as the infrastructure’s impact on use process and user organizational performance. Surveyors consider the PSDI a resource for information from geodetic and cart...
