In statistics, the term “official data” denotes data collected in censuses and statistical surveys by National Statistics Institutes (NSIs), as well as administrative and registration records collected by government departments and local authorities. They are used to produce “official statistics” for the purpose of making policy decisions, and to facilitate the appreciation of economic, social,...
A new 1 km global IIASA-IFPRI cropland percentage map for the baseline year 2005 has been developed which integrates a number of individual cropland maps at global to regional to national scales. The individual map products include existing global land cover maps such as GlobCover 2005 and MODIS v.5, regional maps such as AFRICOVER and national maps from mapping agencies and other organizations...
The China-Pakistan Economic Corridor (CPEC) is a multi-billion-dollar collection of ongoing and planned Chinese projects in Pakistan ranging from infrastructure development to the establishment special economic zones sharing technical expertise by China. For China, it an integral part its ambitious Belt Road Initiative (BRI) through which aims establish hegemony Eurasia Africa. Pakistan, opport...
Widespread use of spatial databases[24] is leading to an increasing interest in mining interesting and useful but implicit spatial patterns[14, 17, 10, 22]. Efficient tools for extracting information from geo-spatial data, the focus of this work, are crucial to organizations which make decisions based on large spatial data sets. These organizations are spread across many domains including ecolo...
With the rise of China and the implementation of the “21st Century Maritime Silk Road” strategy, research on geo-economics between China and ASEAN (Association of Southeast Asian Nations) countries has become increasingly important. Current studies mainly focus on influencing factors, while there is little consideration about how these influencing factors act on geo-economic relationships. Ther...
Data reliability is a major concern for both science and policy analysis. Methods of specifying the reliability of sample data, the variance around measures of central tendency, the confidence we should put in statistical summaries, etc. are well developed. When data are geo referenced, however, reliability estimates have not traditionally been mapped. For the same reasons that we map spatial d...
Database support for multidimensional arrays is an area of growing importance; a variety of highvolume applications such as spatio-temporal data management and statistics/OLAP become focus of academic and market interest. RasDaMan is a domain-independent array database management system with server-based query optimization and evaluation. The system is fully operational and being used in intern...
The European indoor Radon map which is currently under production is based on gridded data supplied by the contributing countries. Each grid node represents the arithmetic mean (among other statistics) of the individual measurements within 10 x 10 km(2), called cells, pixels or blocks, which are aligned to a common metric coordinate system. During work the question emerged, if uncertainty in th...
Digital photos are an important aspect of the modern multimedia experience. The contributions of online collaborative communities can now be leveraged for the task of automated image annotation. We present a web tool, SpiritTagger, which suggests tags for a user’s photo provided the location where it was taken. We accomplish this on a world scale by mining data from nearly 1.5 million geo-refer...
The mass spectromctnc study of the vaporization of the compounds GeO (hex) and GeO(am) and of the mixture GeO (hex) + Ge(c) made it *Z possible to establish their mode of vaporization: Ge02(hex) GeO(g) + 1/20 (I) n GeO(am) (GeO) (g) (n 1. 2. 3) (II) n n/2 GeOJhex) + n/2 Ge(c) (GeO) (g) (n = 1,2,3) (III) c. n The enthalpies of vaporization are AH° (I) 121. 2± 1.6 kcal/mole AH» (II, n=l) = 53.4 ±...
