Raster datasets record a value for all points in the area covered which may require more storage space than representing data in a vector format that can store data only where needed. Raster data is computationally less expensive to render than vector graphics; Combining values and writing custom formulas for combining values from different ...
In computing, a bitmap (also called raster) graphic is an image formed from rows of different colored pixels. [1] A GIF is an example of a graphics image file that uses a bitmap. [ 2 ]
Data from Conservation International on areas of the world with especially high endemism and high numbers of threatened species. Pilot Analysis of Global Ecosystems: Forest Ecosystems: Data from the World Resources Institute includes: percentage tree-cover, population density and tree cover, share of wood in fuel consumption, etc.
The Geospatial Data Abstraction Library (GDAL) is a computer software library for reading and writing raster and vector geospatial data formats (e.g. shapefile), and is released under the permissive X/MIT style free software license by the Open Source Geospatial Foundation.
A hybrid topological data model has the option of storing topological relationship information as a separate layer built on top of a spaghetti data set. An example is the network dataset within the Esri geodatabase. [23] Vector data are commonly used to represent conceptual objects (e.g., trees, buildings, counties), but they can also represent ...
Data extraction is a GIS process similar to vector overlay, though it can be used in either vector or raster data analysis. Rather than combining the properties and features of both datasets, data extraction involves using a "clip" or "mask" to extract the features of one data set that fall within the spatial extent of another dataset.
