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?
Telephone/Network services: GIS Data is used to incorporate geographic data into the complex network design, planning, optimisation, maintenance and activities. It provides a location based service for engineering applications and customer relationship management.
When new geographic features become visible as you zoom in on a Web Map This is referred to as?
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.

How do I know my Dem resolution?
Spatial Resolution refers to the cell size (the area covered on the ground and represented by a single cell). See here under ‘Types of Resolution’. 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.
