Chapter 3. Discovering Physical Relationships

In this chapter, we will create an application for a raster physical modeling example. First, we'll use a raster analysis to model the physical conditions for some basic hydrological analysis. Next, we'll redo these steps using a model automation tool. Then, we will attach the raster values to the vector objects for an efficient lookup in a web application. Finally, we will use a cloud platform to enable a dynamic query from the client-side application code. We will take a look at an environmental planning case, providing capabilities for stakeholders to discover the upstream toxic sites.

In this chapter, we will cover the following topics:

• Hydrological modeling
• Workflow automation with graphical models
• Spatial relationships for a performant access to information
• The NNJoin plugin
• The CartoDB cloud platform
• Leaflet SQLQueries using an external API:CartoDB
