show ()Ī raster data model uses an array of cells, or pixels, to represent real-world objects. If this does not seem intuitive, think of three connected lines defining a triangle: they can represent three connected road segments (thus polyline features), or they can represent the grassy strip enclosed by the connected roads (in which case an ‘inside’ is implied thus defining a polygon). If it isn’t, then you are working with a polyline feature. They also embody the idea of an inside and an outside in fact, the area that a polygon encloses is explicitly defined in a GIS environment. Sometimes you will see the words lattice or area used in lieu of ‘polygon’. show ()Ī polygon is composed of three or more line segments whose starting and ending coordinate pairs are the same.
