We’re going to talk about a DuckDB-Wasm web mapping experiment with Parquet. But first we need some context! Common Patterns Every application is different, and most architectures are unique in some way, but we sometimes see common patterns repeated. The diagram below shows a common pattern in web mapping. Figure 1: A common high-level architecture …

Here at Sparkgeo, while we often prefer to provide answers over visualizations, we still make a lot of web maps. And when we do, we take pride in producing high-quality cartographic products. Cartography is a vast subject, encompassing everything from overall page design to the smallest detail in typography. The representation of geographic features with …
FOSS FMV FTW: A tutorial on how to accurately map video onto a map, using open source software and standards (STAC & STAC API, Mapbox, MapLibre).
If you are creating a Mapbox GL map using React, there may come a time when you want to be able to trigger Redux or other actions from within said popup. If you’re not using react-map-gl, this article is for you. If you’re looking for spoilers, see this codepen for a full implementation. What sets …
This is a continuation of the accessible web maps blog post that I wrote in May of 2019. In that post I outlined some general accessibility techniques and how to apply them to web maps. I didn’t consult with anyone with a disability for that blog post, it was mostly a digest of my experience …
Continuing from disruption in the geospatial age pt 1 where we talked about classic disruption business models and in particular referenced Boundless, Esri and Mapbox. I wanted to highlight another example describing how Planet and DigitalGlobe have been reacting to a highly complex technology & consumer environment.
How grand I am to throw around terms like ‘the geospatial age’ as if I’m some kind of luminary. It sounds wonderful that we might be in some kind of ‘age’, but really, what on Earth does that mean? Well, what I mean is we as a technology community we are closer to geospatial technology […]
How Exciting! I’m not sure if this was a deliberate Easter Egg in Apple’s WWDC website, I have a sneaking suspicion it might be, but we’ve just had a glimpse of an Apple Maps web API. Traditionally, Apple Maps have been available only in native iOS apps. It seems that might be about to change. […]
As we all know, a demo is worth at least a thousand words. earlier this week I put together this client side demo to help our clients get the feel of the kind of things we can do with Maptiks. I wanted to share it with all our Sparkgeo friends too. Welcome to the future […]
I had made the assumption that CartoDB was all about data delivery. Much like the deprecated Google Maps Engine, I had assumed CartoDB’s value was really in fast data rendering and distribution.
