With the expeditious development in Geographic Information System (GIS) and their applications, leads to the increment in the geo-graphical databases that have been developed by different vendors. However, the amalgam of data and accessing is still havoc for the development of GIS. Spatial or geometric data types provide basic abstraction for modeling the geometric structure of objects in space and building the relationships among objects, properties and their operations. Operations on spatial data types include spatial operations on the area of a region, topological relationships checking the relative position of spatial objects to each other like overlap, meet, disjoint, or inside, and cardinal direction relationships like north or southeast.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
