Digital Elevation Model

i am wondering if it is possible to plot a colormap/contourplot with bokeh like the tricontourf style in matplotlib. I would like to plot an elevation model and read the z value with the great hover tool. I tried for a while but did not find a solution.

It’s certainly possible to draw a contour plot, but there is nothing currently built in to Bokeh to compute the contour levels. You would need to compute the iso-contours yourself, and pass them explicitly to multi_polygons.
