His focus is identifying urban areas that are at risk of flooding. He has used GIS to develop a model that can be applied cheaply and systematically wherever it is needed. He is basing his model on freely-available elevation and land-use data. Starting with elevation data, he develops a stream and drainage model. He also develops a land use model based on aerial photos. He combines the two models to identify populated areas that are close to risky waterways. His model is built on the ArcGIS programming interface. Towards the end of the demo, he showed a way of generating a Python script from the model graph. We talked about the new [Google Earth Engine](https://earthengine.google.com/) project. In that environment, Google gives you access to high-resolution (and expensive) data sets. You run your processing on Google's platform, and you get the results of your analysis. However, you can not download the high-res data yourself. We discussed the tradeoffs of using Google's high-res data vs using lower-res freely-available data. His vision is to make this model available for anyone to use, so they can easily identify high-risk areas in any urban setting. Further, he wants to make that information available through a mobile app using geolocation. Thanks for a great meeting, and we'll [see you in June](http://foxpython.tumblr.com/post/143768552872/june-meeting)!
