How do i collect mult temporal satelite imagery?

Question

I am doing a project on change detection on remote sensory images over India. I need images of the same place on two different time instances. However i am only able to find images of certain place in a particular time (not selected by me).

OK,that was my mistake(somehow i was unable to find similar question),however question is still unanswered. — vkSinha, Jun 06 '18 at 04:59
Not necessarily , all i want is good data for change detection! — vkSinha, Jun 11 '18 at 06:04

Sentinel-2 provides repeat passes of most of the Earth's surface.

If your location is within the United States, you can download imagery from the National Map Viewer.

You can access multiple years of Landsat data here: https://earthexplorer.usgs.gov

Sentinel data can be found here: https://earthexplorer.usgs.gov And this post explains how to access the data: https://gisgeography.com/how-to-download-sentinel-satellite-data/

Landsat has global coverage and decades of data, but you may want to be careful that the data you are accessing has the same satellite footprint / spatial resolution. The newest data, of higher ewsoluation, can be matched to the 30m resolution of older data by resampling the Imagery if you want to use a consistent spatial resolution.
