Phenomena can gradually vary along a continuous raster from aspecific source. A raster depicting an oil spill can show how the fluid moves from high concentration to low concentration. At the source of the oil spill, concentration is higher and diffuses outwards with diminishing values as a func...
Vector Data and Raster Data in GISAli Jaafar
You have been asked to prepare a lesson that explains to beginning GIS users the difference between vector and raster data. Also, to be included in the lesson is a basic explanation of a land-cover dataset that has been derived from satellite imagery. You have chosen the Great Salt Lake ...

aFully Automated Techniques that convert raster-to-vector were assumed to be the next step in GIS data capture. However, the expectation for a definitive solution faded in the face of the richness and complexity of geographic and engineering infor- mation held on maps and plans. Nearly all GIS...
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 ...
