CARTO users want to see maps drawn quickly, and drawing maps quickly means rendering every geometry in a table to an output format. By deploying the latest version of PostgreSQL to our infrastructure, we are taking advantage of improved parallel query support to make our maps and widgets go faster.Read more
It’s with a lot of pride that we’re releasing CARTOframes, a Python package for interacting with CARTO that’s built specifically with data scientists in mind.Read more
At CARTO we <3 PostGIS. And we love PostGIS not only because it’s a fully-fledged geospatial analytics engine but because being at the roots of our technology it helps us building tools to help companies and individuals better understand their geospatial data through Location Intelligence.Read more
More and more CARTO users are asking to render more and more data onto maps, and they want to see the results on their screen quickly. In order to get a whole map drawn in less than a second, the individual tiles visible on a map have to arrive even faster!Read more
With the last release of PostGIS, a new set of functions were added to generate Mapbox vector tiles (MVT). The most important of these functions is
ST_AsMVT which allows users to create a full tile from a SQL query. Björn Harrtell completed the majority of the project, with partial sponsorship from CARTO.
One of the most important parts of our infrastructure is how we generate tiles. This process consists of two parts: gathering data and rendering tiles. As part of our mission to maintain the best possible product for our clients, we set out to improve the performance of our tiles. To do so, we needed to better understand and measure the tile rendering process. We determined that data gathering had a much wider improvement margin due to it’s time and resource consumption compared to actual tile rendering.Read more
In the geospatial world it is easy to find really small datasets, like an excel file with client locations or a geojson with the coordinates for a few thousand Starbucks coffee shops. Those cases are usually easy enough to deal with that even the browser can load, process and visualize without major problems.Read more
