Vector tiles Training

Vector tiles are packages of geographic data, packaged in predefined "tiles" of approximately square shape for transfer to the web. This is an emerging method of providing stylised web maps, combining some of the advantages of pre-rendered raster map tiles with vector map data. The server returns vector map data, which has been clipped to the boundaries of each tile, instead of a pre-rendered map image and it is the client that generates the image by applying a pre-defined style.

The data transfer is considerably reduced compared to a raster tiled map, as the vector data is generally much smaller than a rendered bitmap image. The style is applied later in the process, or even in the browser itself, allowing greater flexibility in the presentation of the data, and even providing interactivity with the map elements, since their vector representation already exists in the client.

Another advantage is that the processing power of the centralized server is less important since it is the client that is responsible for rendering using its own GPU.

In this course we will learn how to generate custom vector tiles, and apply a style to them, based on OSM data. We will also learn the principles of optimising both the tile generation and the styling to enable fast rendering of images in the browser. We will also discuss different approaches to bringing tiles online in a productive way
