This is only limited by the speed of the computer or the download speed of the internet connection. This adds a fluid and dynamic nature to the use of a tile package, providing quick mapping transitions when zooming and panning about a map layer. Vector tile size also helps with the speed of use and the scalability of the view. This can be of particular importance when displaying over cloud or web based applications, due to a lower download amount required. Vector data usually is of much smaller file size than a rasterised image, hence overall package size can be greatly reduced when transferring or hosting the map tiles. One primary advantage is that the data transfer in a map view is significantly reduced. Several advantages exist in the use of vector tiles over that of pre-rendered raster image tiles. In comparison with raster image tiles, vector tiles are able to lever the power of map tiling caching, scaling and processing speeds, while using vector data rather than pre-rendered raster image data. This is packaged into a collection of tiles for viewing on a desktop platform or web mapping application. Vector tiles are a bundles of geographic data that have been trimmed to a specified location, which is usually rectangular in shape. ![]() ![]() But, what are vector tiles and how do they differentiate from other approaches to presenting large collections of geographic data? Vector tiles are fast being adopted as the preferred option in viewing and transferring geographic data in desktop GIS and web mapping applications. ![]()
