2 days ago · Vector Data: A representation of the world using points, lines, and polygons. Vector models are useful for storing data that has discrete boundaries, such as country borders, land parcels, and streets. In the vector data, the spatial information are recorded as x, y coordinates. The point features are recorded as single x and y pair of coordinates.

EEA templates and data, for map production in accordance with EEA Guidelines.

From building databases and administrative boundaries to geonames and points of interest (POI), we have an innumerable amount of GIS and vector datasets from around Geographic Information System software such as ArcGis or QGis are commonly used to work with these data, in this series of post I want to show the GIS capacities of R. Spatial data come in two category: vector-type: spatial data are represented as discrete elements such as points (cities), lines (rivers) or polygons (countries). The objective of this section is to understand how vector data models are implemented in GIS applications. In contrast to the raster data model is the vector data model. In this model, space is not quantized into discrete grid cells like the raster model. Vector data models use points and their associated X, Y coordinate pairs to represent the 2 days ago · Vector Data: A representation of the world using points, lines, and polygons.
