What is the best spatial resolution?

The finest resolution as of now is 30cm provided by very high-resolution commercial satellites….We generally stick to the following subdivision of satellite images:– Low resolution: over 60m/pixel.– Medium resolution: 10 ‒ 30m/pixel.– High to very high resolution: 30cm ‒ 5m/pixel..

Which are the 4 types of raster resolution?

When working with imaged raster data, there are four types of resolution you might be concerned with: spatial resolution, spectral resolution, temporal resolution, and radiometric resolution.

What is reference scale?

In GIS, Reference Scale is the scale at which symbols and labels appear on a map at their intended, true size. … With no reference scale, symbols and labels dynamically adjust to look the same at all map scales.

What are the GIS applications?

Multiscale maps allow you to view geographic data across a range of scales—also known as zoom levels—from buildings to the entire globe. Specifying at what zoom levels content is drawn is known as setting the visible range. … Your map may contain many layers, each with its own visible range.

Therefore, if the cell size is 5 x 5 meters, the resolution is 5 meters. You can check the cell size by right-clicking on the raster dataset > Properties > Source tab.
