Change detection on rasterized data is extremely dependent on accurate radiometric and geometric rectification. The development of processing tools able to minimise these requirements has been recognised since the late eighties. In the present paper we present a methodology for detecting changes on multidate satellite images with different radiometric and geometric characteristics via Multireso...

Two distinct approaches can be identified in the modelling of spatial data, one that considers discrete spatial objects and another that considers continuous spatial changes. The first approach fits better cartographic applications whereas the second is commonly used in the modelling of continuous changes of physical phenomena such as temperature, elevation, atmospheric pressure, etc. Due to th...

purpose of this study is analysis of spatial auto-correlation of freezing changes of iran over the last half century. daily temperature data over the period 1340 - 1383 of esfezari database provided by doctor masoodian (to enhance the temporal resolution of the database, daily observations of temperature from 1383 to the end of 1390 using the same method and the same spatial resolution is added...

structure and function of socio – economic systems present different spatial effects in different countries of the world. in this study, structure and function of social and economical systems is analyzed to identify of changes within urban spatial structure. in tehran, effects of political and economic factor is analyzed for identification of changes of its spatial structure and its periphery ...
