In imagery resolution represents the amount of area each pixel of an image covers. For example, an image with 1 meter resolution means that each pixel in the image is the width and height of 1 meter, this means any objects which are smaller than a meter will not be visible in an image. The smaller the resolution = the higher amount of detail an image will have. Low resolution imagery however is excellent for use over large areas and looking at more general patterns and datasets. If a map is needed with an image over a district, a lower resolution image would be better than a very high resolution image. However, when looking at specific areas such as a specific SHA or CHA, high resolution imagery is needed.

Satellite imagery is available to the global community with costs varying between providers. Archival imagery (imagery not obtained the day of request or planned in future tasking’s) is often discounted by imagery providers, so if you can use an image that is a few days old or even a year or more older the costs to obtain that image are significantly reduced. Also the benefit of satellite imagery is that the image provider will pre-process the imagery so you will be able to immediately use it in your GIS with no preparation required on your part. You can also obtain satellite imagery in many different resolutions both high and low.
