Introduction

Can people be seen from artificial satellites? -Summary of GSD & revisit/local time satellite index-

Can we see people from satellite images? We will introduce "GSD," "revisit time," and "local time," the indexes to gain knowledge of satellite image specifications.

Introduction

The basics of satellite data — What it tells us, types, observation interval, resolution and use cases

What can we actually gain to know from satellite data? How do we gain this knowledge? How frequently? How is satellite data used in the actual real world? We are going to answer all these questions.
