Abstract

Optimizing the visualization and query function of web GISs needs to be considered when developing any web GIS application. Tiled map, especially raster tile has been provided by serveral GIS servers, such as ArcGIS server and GeoServer with the aim of increasing the visualization performance. Nevertheless, raster tiles could only provide data in the form of images. It leads to difficulties while querying data. Vector tile was proposed to improve those drawbacks of raster tiles. This paper presents the backgrounds of tiled map, including both raster tiles and vector tiles. The process of developing vector tiles services using an open sources software (PostgreSQL) and two frameworks (NodeJS and MapNik) is also introduced.
