Description:

Catastrophic floods had a deep impact on the early human psyche resulting in a potpourri of great flood stories ingrained in the mythology of early human civilisations spread across the globe. Despite all the human progress floods can still cause massive property damages, economic losses and casualty. Several major cities and towns in India reported a series of devastating urban floods in recent times, and the resulting human and financial loss makes study of models that can identify the flood risk of an area extremely relevant.

This talk focuses on geo-spatial analytics and describes multiple techniques that can be used to assess the flood inundation risk of a geographical area. The techniques use freely available data captured by different satellites. The talk will demonstrate how we can use python libraries and Digital Elevation Models (DEM) to analyse a terrain with respect to it's elevation. The talk also also focus on how to build a first order flood fill model to identify flood inundation risks of a geographical area due to overflow of water from a nearby water body, and due to heavy rains.

Some key take-aways from this talk are

1. An introduction to various types of Remote Sensing data with extensive focus on Digital Elevation Models (DEM)
2. Various types of public data sources available for Geospatial Analytics
3. Working with translator library for raster and vector geospatial data like GDAL
4. How to use other geospatial libraries like PyDEM for topographic analysis
5. Descriptive Analytics using Python packages like numpy, pandas, scikit-learn, seaborn, matplotlib etc.

Prerequisites:

• Basic / Intermediate knowledge of Python
• Interest in Geospatial Analytics using Python or curiosity in application of analytics for catastrophic risk management
