Overview of this book

We start with the perplexing task of extracting value from huge amounts of barely intelligible data. The data takes a convoluted route just to be on the servers for analysis, but insights can emerge through visualization and statistical modeling techniques. You will learn to extract value from IoT big data using multiple analytic techniques. Next we review how IoT devices generate data and how the information travels over networks. You’ll get to know strategies to collect and store the data to optimize the potential for analytics, and strategies to handle data quality concerns. Cloud resources are a great match for IoT analytics, so Amazon Web Services, Microsoft Azure, and PTC ThingWorx are reviewed in detail next. Geospatial analytics is then introduced as a way to leverage location information. Combining IoT data with environmental data is also discussed as a way to enhance predictive capability. We’ll also review the economics of IoT analytics and you’ll discover ways to optimize business value. By the end of the book, you’ll know how to handle scale for both data storage and analytics, how Apache Spark can be leveraged to handle scalability, and how R and Python can be used for analytic modeling.

Preface

Vector-based methods


There are two main categories of geospatial analysis and file types, vector and raster. Vectors are all about shapes, while rasters are more about grids. Vector is more common due to flexibility and efficient storage. Vectors can be defined simply by using a set of points. There are three main types of vector geometry:

  • Points: This can be defined in two or three dimensions. It is the common latitude, longitude pair you are probably very familiar with. The airport locations used in the R code previously are examples of points.
  • Lines or LineString: A LineString is defined by a set of points and order is important. More than one LineString can be stored together; in that case it is called, unsurprisingly, a MultiLineString. A river system or roadways network is an example of a MultiLineString. A file that contains a MultiLineString for the US Interstate roadways network can be downloaded from the University of Iowa GIS Library (ftp://ftp.igsb.uiowa.edu/gis_library/USA/us_interstates...
