This comes up all the time in dealing with geospatial rasters.

For instance, in GDAL there's a whole RFC for dealing with issues related to pixel corners versus pixel centers!

"Traditionally GDAL has treated this flag as having no relevance to the georeferencing of the image despite disputes from a variety of other software developers and data producers. This was based on the authors interpretation of something said once by the GeoTIFF author. However, a recent review of section [section 2.5.2.2] of the GeoTIFF specificaiton has made it clear that GDAL behavior is incorrect and that PixelIsPoint georeferencing needs to be offset by a half a pixel when transformed to the GDAL georeferencing model."
