Mapserver - A Google-Maps-like Interface to your DataΒΆ

The mapserver is a new, experimental feature. It’s based on Leaflet, a library written to create zoomable, map-tile interfaces. (Similar to Google Maps.) yt provides everything you need to start up a web server that will interactively re-pixelize an adaptive image. This means you can explore your datasets in a fully pan-n-zoom interface.

To start up the mapserver, you can use the command yt (see Command-Line Usage) with the mapserver subcommand. It takes several of the same options and arguments as the plot subcommand. For instance:

yt mapserver DD0050/DD0050

That will take a slice along the x axis at the center of the domain. The field, projection, weight and axis can all be specified on the command line.

When you do this, it will spawn a micro-webserver on your localhost, and output the URL to connect to to standard output. You can connect to it (or create an SSH tunnel to connect to it) and explore your data. Double-clicking zooms, and dragging drags.


This is also functional on touch-capable devices such as Android Tablets and iPads/iPhones. In future versions, we hope to add halo-overlays and markers-of-interest to this.
