Measurement pixel size on Hyperspectra measurements

[borondics]

A user is asking if they could change the plotted pixel size for non-uniform maps (left on image). This could be an interesting use case but I am unsure how difficult it would be for implementation.

Also, it brings up other questions for regular raster maps: what happens if we plot a measurement with 10 micron aperture but 5 micron step size...? Measurement software and Quasar as well just plots the center of the aperture with a size of neighbouring center distance divided by two. Can we come up with a better way?

What if we have the opposite: a small aperture but large step, so the measurements never touch each other? For example in OPTIR?

This is an old but tricky problem. The function that we use to synthesize the map image array works best for a single, dense, hyperspectral cube like you get from an array detector. With point maps you often get grid mismatch between different measurement regions (as shown here), and this also happens when you combine maps (#567) or if there's variation in the position (#572) There's generally no information in the data file about aperture/spot size so we always default to span.
