Esri recently removed the “beta” label from its implementation of vector tile maps, bringing this exciting new technology within the reach of ArcGIS enterprise customers. Vector tiles can now be authored in ArcGIS Pro and published to Portal or ArcGIS Online.

Currently, many GIS enterprises, especially governments, maintain raster basemaps on the ArcGIS platform. In recent years, Esri enterprise customers have watched companies like Mapbox dazzle the cartographic world with vector tile mapping and wondered when the benefits of vector tiles will be within reach. Esri finally introduced their own vector tiles in late 2015, built with industry-standard Mapbox specifications. 

Vector tiles offer enormous promise: high resolution graphics, better performance due to client-side rendering, significantly smaller storage and bandwidth needs, and the ability to apply multiple styles to a single set of cached tiles without having to re-cache. Users can quickly hide layers, change symbology, and ensure consistency using a clear plain-text format or a web-based style editor. With all these benefits, what do you need to know before leaving your raster basemaps behind? 

Cartographer Kate Leroux will share what she’s learned developing a vector tile basemap for the City of Seattle. She’ll demonstrate some paradigm shifts in how cartographers should organize a basemap, as well as best practices and new opportunities in vector mapping, advice on how to accomplish this transition efficiently, and a host of smaller tips, tricks, bugs, and stumbling blocks to avoid. 

Intended audience: GIS professionals who currently maintain raster basemaps
