A unification data model of vector and raster UNM is proposed in this paper. UNM divides the 0-, 1- and 2-dimension space into irregular sub-spaces. Relationships among these sub-spaces are explicitly built and these sub-spaces are organized as hierarchy. Features on the map are expressed ...

Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software. ...
First,to give cartographers an off-the shelf solution for creating small-scale world, regional, and country maps. To this end, Natural Earth Vector includes both cultural and physical features and builds on Tom Patterson’s Natural Earth raster data, first introduced in 2005. ...
raster data and designed an improved method to vectorize RS classified data.The algorithm was developed using VC++.The experiment was performed using real data to analyze the results of the vectorization time efficiency by the comparison between the method in this paper and an existed one.It can...
To demonstrate the capabilities of GDMS-R, we present a use case relative to the deep impact of increased urbanization on the vulnerability of peri-urban hydro-systems: impact of the linear constraints on the runoff water pathways and accumulation that uses both vector and raster data in an ...

Spatiotemporal data often comes in the form of dense arrays, with space and time being array dimensions. Examples includesocio-economic or demographic data, environmental variables monitored at fixed stations, raster maps time series of satellite images with multiple spectral bands, spatial simulations,...
