Doing Geospatial analysis with Python
krishna lodha, Jashanpreet Singh, Aman Bagrecha

This workshop will provide an introduction to performing common GIS/geospatial tasks using Python geospatial tools such as OWSLib, Shapely, Fiona/Rasterio, and common geospatial libraries like GDAL, PROJ, pycsw, as well as other tools from the geopython toolchain.

Sentinel-1 Image Analysis: Flood Detection using Cloud Native Tooling
Aman Bagrecha

Flood Detection from Sentinel-1 imagery has traditionally relied on thresholding approaches. Conventional methods often face challenges in regions where the surrounding areas also exhibit low backscatter, resulting in inaccurate results. Furthermore, processing and conducting large-scale analysis pose significant challenges.
In this presentation, we aim to overcome these limitations by harnessing the power of Deep Neural Networks (DNN) and supplementary data, such as elevation and land-cover information, to enhance flood detection accuracy. This approach centers around training a neural network using open source cloud2street flood dataset. To achieve large scale analysis we leverage the capabilities of the Cloud Native Geospatial Tools, which helps us avoid downloading data when performing inference.
