Intensity estimation is a common problem in statistical analysis of spatial point pattern data. This paper proposes nonparametric Bayesian method for estimating the process intensity based on mixture finite (MFM) model. MFM approach leads to consistent and simultaneous estimate surface clustering information (number clusters configurations) subareas surface. An efficient Markov chain Monte Carl...

The National Map (TNM), being developed by the United States Geological Survey (USGS), is created from many data sources and Web Map Services (WMS) owned by many organizations. TNM data sources are electronically stored at various scales and resolutions. Consequently, when data are extracted from several WMS and horizontally integrated in geospatial data applications, the differences between da...

The U.S. Geological Survey (USGS) maintains a place-based research program in San Francisco Bay (USA) that began in 1969 and continues, providing one of the longest records of water-quality measurements in a North American estuary. Constituents include salinity, temperature, light extinction coefficient, and concentrations of chlorophyll-a, dissolved oxygen, suspended particulate matter, nitrat...

In September 2010, the USGS began publicly releasing earthquake alerts for significant earthquakes around the globe based on estimates of potential casualties and economic losses with its Prompt Assessment of Global Earthquakes for Response (PAGER) system. These estimates significantly enhanced the utility of the USGS PAGER system which had been, since 2006, providing estimated population expos...
