I'm new to Remote Sensing and Data Processing, and interested in fusion.

Where do I find georeferenced data that can be fused together?

It can be either of the following:

  1. Satellite image and drone image (multi/ hyper spectral)
  2. Satellite image (multi/ hyper spectral) and spectroradiometer data (quantitative)

For satellites, I think I can go with Landsat images, but which one should I use/ where do I find the corresponding second data to fuse together.

  • For open data I think the best place to seek data is the Open Data Stack Exchange. – PolyGeo Jun 20 '18 at 9:11
  • Thank you, didn't know about the sub-stackexchange. Will check out Open Data for information. – thegravity Jun 20 '18 at 10:12
  • what is the purpose of fusing Landsat data (30 m) with drone data (a few cm). the difference in spatial resolution is so large that you are very unlikely to get a meaningful result. – radouxju Jun 20 '18 at 11:57

  • @radouxju landsat was just an example I used. I'm willing to try the process with multiple and varying spatial resolution data to understand the differences and difficulties. – thegravity Jun 21 '18 at 5:19

A good starting place to begin might be to look at the Sentinel Missions with Sentinel 1, 2 and 3. You can see details here.

This data is freely available for download from a few platforms but I would recommend the Rocket Project from Mashup for any new people to remote sensing, which can be found here. An important thing to consider is the temporal resolution of the data because this may cause unwanted and unexpected results after fusion implementation.

Sentinel 1 uses radar, Sentinel 2 is multi spectral and Sentinel 3 has a wide range of instruments but the one you may be interested in is for land surface temperature.

You can then use the Sentinel Application Platform (SNAP) which is free to download to help you pre-process them and can be found here..

Other than that it is just a case of choosing any other software you might want to use and having a look online and in books for some detailed workflows.
