Previous studies have shown that when a crime occurs, the risk of in adjacent areas increases. To reflect this, previous grid-based prediction combined all cells surrounding event location to be predicted for use model training. However, actual land is continuous rather than set independent as geographic information system. Because patterns occur according detailed method vary, it necessary spa...

This paper determines alternative indexes to measure banking competition from the perspective of industrial economics. Spatial correlation of competition in China’s banking environment is studied from the perspective of spatial economics. A spatial panel data model is built to make an empirical study of factors influencing banking competition. The results show that the global autocorrelation te...

Drought is one of the environmental events and an inseparable part of climatic fluctuations. This phenomenon is one of the main characteristics of the various climates. Awareness of spatiotemporal behavior is effective in land planning. The spatial statistical methods provide the means by which they analyze the spatial patterns of random variables such as precipitation. In this study, using the...

Spatial-frequency characteristics of letter identification are much better understood in the fovea than in the periphery. The purpose of this study was to compare the spatial-frequency characteristics of letter identification in central and peripheral vision. We measured contrast thresholds for identifying single, Times-Roman lower-case letters that were spatially band-pass filtered. Each of th...

It is widely recognised that Spatial Data Infrastructures should support and facilitate the network of spatial data flows between organisations. This chapter focuses on the characteristics of the nodes in this network, which are the organisations that access, use and share spatial data to support their (business) processes. Case study research findings are presented which suggest that structura...

temporal and spatial variations of fire behavior can be predicted using one of the semi-physical or empirical models developed over recent years. this article investigates the effect of different fuel moisture conditions on fire spread and behavior in national golestan park in july 2011 using farsite, flammap simulation systems, and previous ignition history. landscape data contains the topogra...

Spatial analysis as the main approach of geography was reviewed and searched through its historical development. The results of this exploratory research showed that this approach was born after the Second World War due to the overall interest of geographers to develop universal theories and laws. The advocators of this field believed that the old regional geography was not able to develop ...
