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

Summing it all up


So, what have you learned so far just by some quick slicing and dicing of the data? You learned that the dataset does not have a complete history for every weather station over the period. We identified that records are probably sent when there is something to report, and there is not a record for every 15 minutes of every day. We found some stations that only report once a month on the 1st day.

We detected a potentially useful pattern with the accumulated level of precipitation over time. An extreme event was identified in the data and was externally verified as an actual occurrence. You learned the statistical distribution of values for each field in the data using R.

The geographical distribution of stations was also explored. You learned that stations are not evenly spaced across the state of Colorado (although not too bad for the range of area covered). We also identified some data values that appear to be acting as an indicator instead of a measurement (-9999, 999.990...
