Analytical geospatial Digital Earth

Information from imagery: ISPRS scientific vision and research agenda

“…Their utilisation has already had a profound impact on managing geospatial knowledge, structuring and automating workflows within and across organizations that deal with location-based information and intelligence, and bringing geospatial data into people's daily life through geobrowsing or the geospatial web. Recent research efforts have been directed towards smart or intelligent geoprocessing on the web, which involves semantics-enabled web services, intelligent service discovery, dynamic and automatic service chaining and composite workflows, and service load balancing, ideally based on personalized user or application preferences (Li et al 2011;Veenendaal et al 2014).…”

A topographically preserved road‐network tile model and optimal routing method for virtual globes

“…In respect of data organization, a discrete global grid system (DGGS; Goodchild & Kimerling, 2002;Sahr, White, & Kimerling, 2003) discretizes the globe into a multi-resolution hierarchical pyramid of indexed regular regions that are generally called tiles (Figure 1a). Virtual globes arrange geographical data into tiles based on DGGS to speed up the display and update of three-dimensional (3D) interactive scenes (Figure 1b), which is the basis for spatial analyses and assessments from local to global scales (Mahdavi-Amiri, Alderson, & Samavati, 2015;Veenendaal, Li, Dragicevic, & Brovelli, 2014;Zheng, Xiong, Gong, & Yue, 2017).…”
