Base maps provide us with the foundation to visualise and analyse data using the ArcGIS platform. But with a range of options now available, have you ever wondered if you’re using the right base map within your solution?
Technology’s rapid evolution is driving the need to utilise fast rendering tiles, which is why vector seems to be getting all the coverage these days. However, raster tiles remain very useful for many tasks and workflows.
So vector or raster? There is a place for both types of tiles. Making the right decision as to what’s best for you and your customers really comes down to your specific needs.
Previously I spoke about the Dynamic Tile Service and how it creates tile images in real-time; its ability to easily create custom styles and colours for maps; and, its ability to tile point and polygon data sets.
In this post I will be talking about how the Dynamic Tile Service can further solve Big Data problems by allowing users to view thousands of interactive features such as pop-ups showing point detail instantly when the browser loads using the UTFGrid JSON web service.
As we have previously stated, viewing Big Data on a map brings a unique set of challenges to web based applications as browsers cannot process massive data sets all at once, instantly. This leaves users waiting for information to load and is probably contributing to the bounce rate of many web-based map applications.
Following on from Digital mapping’s dynamic makeover, where I touched on the differences between a traditional tile service process, and one which is dynamic, we also discussed how the Dynamic Tile Service can render custom styles and colours on the map tiles it produces in real-time using CartoCSS.
In this post, I’ll be talking Big Data and how the Dynamic Tile Service solves the problem of viewing large datasets on maps in web browsers.
Tiling Big Data to speed up web browser performance
The recent explosion in the popularity of ‘Big Data’ has left many people scratching their heads as to how to properly view a large dataset. Web browsers are not built to download large amounts of data all in one go – so when we try to view a large dataset on a web map, it can feel like putting a square peg in a round hole.
Over the coming weeks I’ll be talking about a new platform we’re calling the Dynamic Tile Service which delivers our high quality map tiles – in a jiffy.
As its name suggests, the Dynamic Tile Service creates map image tiles at the time when they are requested (dynamically) – rather than returning them from a pre-built cache of tile images. This has allowed us to add some pretty nifty features including the ability to support:
