... average data. These three algorithms are developed into three plug-ins for the Stanford Geostatistical Modeling Software (SGeMS), which is a public-domain geostatistical modeling platform (Remy et al., 2008). The three plug-ins are block kriging estimation (BKRIG, ), block sequential simulation (BSSIM...
