I'm having trouble understanding the concept of a Vector tile. My understanding of Vector is point, line, polygon. So buildings, roads, areas etc.
My understanding of Raster is a grid of pixels each with a value to describe it. So the actual imagery would be raster.
I don't understand how a client can request a vector tile and the "imagery" (which I'm used to being raster - .tiff,.png,.jpeg etc) be presented as a vector.
How are these raster images being "vectorized"?
How can points, lines and polygons create something as complex as a raster image?
