The [GEMPAK Conversion Guide](https://unidata.github.io/MetPy/latest/userguide/gempak.html) recommends
`numpy.mean(a, axis=1)` as equivalent to `XAV`, but the NumPy (or xarray) version removes the di…

I want to be able to generate contours that do not include lines on data/nodata borders, 'nodata' being any value either outside the grid or a specifically chosen one inside of it, commonly `f32::MAX`…

If the map doesn't span a large enough area to contain an entire contour, the display is wonky and we get weird shapes with long straight edges instead of nice smooth contours. See the "good" and "bad…

The contour count returned by calling `computeMetrics().length` on a path with one expected arc seems to be inconsistent. The arguments for `startAngle` and `sweepAngle` of `addArc()` and `arcTo()` …

Opening this ticket to start a conversation.
My urban community (https://en.wikipedia.org/wiki/Brest_M%C3%A9tropole) have elevation data as contour data exposed in their open data portal: https://g…

I was hoping to use earcut to replace the glu tessellation functions in OpenGL, but I get different results in some cases. For example, suppose you have 3 non-intersecting nested contours, a square i…

For a given variable, contour lines also need to be standardized (with an option obviously to change it for exceptional circumstances) so that they are the same between comparisons with different mode…

Recent attempts to import the contour-files output from the SVM module into QGIS failed due to geometry problems in the shapefiles produced by SVM. Problems were traced back to two sets of errors. Fi…

Here's a pedestrian isochrone with 15-minute contours:
