Does renaming the tag "resolution" to "spatial-resolution" make sense?

Question

The resolution tag (x 52 posts) has the following excerpt:

The dimensions represented by each cell or pixel in a raster or the detail with which a map depicts the location and shape of geographic features.

It is clearly referring to spatial resolution. At a quick glance, all threads seems to fit under the excerpt guidance.

Could we rename that tag to spatial-resolution?

So, it would not be confused in the future with other types of resolutions, such as temporal, spectral and radiometric.

Complement

There is also the tag map-resolution (x 9). Likewise, resolution, this tag refers to only spatial information:

• resolution of rasters.
• scale of maps.

Answer 1

Not all questions with that tag refer to raster data though that does seem to be the most common thread. Perhaps the Wiki should just be edited to something like 'the granualarity of data samples' or 'the smallest distinguishable unit of measure in data' (expanded on both counts). I'm just wondering if generalizing the existing tag definition would be better than creating additional more specific tags. And whether current or potential future frequency of application of those tags would warrant their creation or reservation now.

I do note a map-resolution tag (x9) that seems fairly synonymous - in fact both are applied to about half the questions.

So I would propose that map-resolution be made synonym of resolution, and the Wiki of that be changed to something like:

Resolution is a measure of the smallest unit or sample in data that can be distinguished from any other, and/or the number of samples for a given unit.

In GIS this often refers to spatial or ground resolution of raster cells or pixels. For example SRTM data can be available at resolutions of 90m or 30m, where one cell with a single, constant elevation value is assigned to a square on the ground 90m or 30m on a side. Satellite imagery is often discussed in terms of resolution, where one image pixel represents 0.5m (high), 15m (mid), or 30m (low). Descriptors such as 'high' and 'low' are somewhat arbitrary, but demonstrate resolution values have a range or spectrum similar to map scales ('large' and 'small').

However resolution also applies to the values measured for that ground distance. In the case of SRTM there is also a vertical resolution since that data measures elevation. Contour lines can easily demonstrate this - each line in the data may represent a difference of 1m, 5m, or 100m. Other resolution type examples include spectral (width on the EM spectrum covered by a single band), temporal (time between samples - minutes, days, or years), or radiometric (the strength or magnitude of a signal).

Note that resolution applies to vector data as well as raster or value. The same section of sinuous river could be represented with a dozen points or a hundred. The more samples along the line, the more detail or resolution with which that feature can be represented in the data.

With the first sentence being the Wiki excerpt as well.
