NTL on specific city or municipality #66

Closed brissyaussieoleh closed 4 months ago

brissyaussieoleh commented 8 months ago

Hello, I would like to ask for help regarding my research. I already have the visualization of the NTL radiance of a specific city or municipality but I was not satisfied with the results because the map is zoomed in and the NTL radiance is pixelated. What is the proper solution for this one? Thank you.

@brissyaussieoleh Thanks for your question! Based on the information you've shared, please note that the NASA Black Marble's spatial resolution is of 15 arc second or roughly ~500m in the Equator. When looking at a city-level, you may see a pixelated image indeed as the resolution is inherent to the upstream data provided by NASA. For instance, you may see a pixelated image on this example.

While this is an intrinsic limitation, I'd love to help you to the best of my capacity. Please free feel share more information about research.

@brissyaussieoleh I would like to check in. Have you been able to use NTL in your research?

Yes, and I need to review the results because I haven't finished my thesis for this one yet.
