Getting started with Satellite Data: Exploration and Processing a talk by Týna Doležalová & Lubomír Doležal

Saturday 16 September 13:20 (30 minutes)

Satellite data has become a valuable resource for addressing various contemporary challenges, ranging from environmental monitoring to urban planning and disaster management. But just looking at single satellite products as they are is not always enough to identify the patterns you search for. We need tools to effectively manipulate vast data to bring forward the details. Satellite data are not all the same – we have optical imagery, radar data, elevation models or satellite measurements of the characteristic of the atmosphere.

This talk should give you an introduction to GeoPython (Python geospatial libraries) and more specifically to using and manipulating satellite data with code. I will introduce you to common libraries and practices like GDAL, Rasterio or QGIS - very known, Open Source helpers.

This talk should also introduce where to search for such data and how to filter, view and download them as even obtaining only what you are interested in presents itself to be a challenge. We will also mention simple indexes which are usually computed from satellite images to highlight a certain phenomenon or help to identify certain patterns observed on a combination of satellite data bands or products. Such indexes are used for example to detect urban settlements or vegetation.

What do you need to know to enjoy this talk

Python level

Medium knowledge: You use frameworks and third-party libraries.

About the topic

No previous knowledge of the topic is required, basic concepts will be explained.

My job description says Geospatial Data Scientist and actually it is something I like very much. Curently I work for Austrian company EOX IT Services where we work on projects mainly for European Space Agency. One of example for all is Green Transition Information Factory project which allows users to interactively discover the opportunities of transitioning to carbon neutrality by 2050 using the power of Earth Observation. I love introducing others to the GeoPython world and Python general, so I restarted PyLadies chapter in Vienna and co-lead mentorship programme for Women+ in Geospatial.

Working at EOX IT Services as a Geospatial IT Engineer on projects for European Space Agency - utilizing web map applications, satellite data visualisation and processing and really enjoying it!

Love escaping cities on a bike, playing board games and teaching Python basic on PyLadies Vienna courses.
