Build your map with a global vector and raster dataset. Use street, satellite, boundaries, outdoor, weather, terrain, and other tilesets to create unique maps.
Vector Streams Grid Streams Delineated Subwatersheds and Stream Networks Summary Concepts • Grid (raster) data structures represent surfaces as an array of grid cells • Raster calculation involves algebraic like operations on grids • Interpolation and Generalization is an inherent part of ...
Most of these models rely on two representations of the geographic space: raster and vector. Both representations have their own strengths and drawbacks. The raster models are simpler to implement and require less data, which explains their success and why most of urban growth models are based ...
Because vector data have vertices and paths, this means that the graphical output is generally more aesthetically pleasing. Furthermore, it gives higher geographic accuracy because data isn’t dependent on grid size. Topology rules can help data integrity with vector data models. Not only that, ne...
When you zoom in on raster data like this shaded relief layer, you can see each cell is the same size. Images: Caitlin Dempsey. Vector data Vector data is split into three types: point, line (or arc), and polygon data. Point Data ...
Each of these models has its own advantages and disadvantages. The vector model uses points and line segments to identify locations on the earth while the raster model uses a series of cells to represent locations on the earth. The figure represents vector (left) versus raster (right) data. ...
1. Natural Earth Data Natural Earth Datais number 1 on the list because it best suits the needs of cartographers. By and large, all the key cultural and physical vector GIS datasets are on a global scale convenient for you to use. The raster datasets also provide beautiful hillshade relief...
As introduced in Sect. 1.3 , geospatial data can be represented by raster grids and vectors. Depending on the data content and operations to be performed on the data, one representation is preferred over th

A raster image is made up of pixels, while a vector image is made up of mathematical equations that define the image's shapes and lines. Raster images are better for photographs and detailed images, while vector images are better for simple designs and logos....
