Vector Data and Raster Data in GISAli Jaafar
A raster grid format is a data model for satellite data and otherremote sensingdata. For raster positions, it’s simple to understand cell size. Map algebrawith raster data is usually quick and easy to perform. Overall, quantitative analysis is intuitive with discrete or continuous rasters. Wha...

GIS矢量栅格一体化无缝连接比例尺匹配Integrating Raster with Vector technology is one of the directions in recent GIS development. On the basis of practice, this paper introduces a GIS system which integrates Raster with Vector . It's design,data management,data matching and integrated analises are ...
Processing both raster and vector data with the same semantic and in an efficient way presents significant challenges to GIS insofar as underlying granularities but also data layout and processing patterns might be absolutely different. We have already focused on the definition and the implementation ...
GIS data models Raster model Vector model Raster types Thematic rasters Image rasters Contain quantities that represent map data such as land use or rainfall May be continuous or discrete Image rasters Contain satellite or air photo data
RS data has increasingly become the most important data of GIS.However,RS data are generally raster data,thus it can not be directly used in GIS for spatial analysis,and usually be classified and vectorized for the application of GIS.The author analyzed the characteristics of RS classified raster...
