An Overview of Lesson 7
The error, accuracy, and precision of the GIS data we use in projects are often overlooked when we download data from various government, open source, and commercial sources. Metadata is data about data. We'll explore these topics in more detail in this lesson.
What will we learn in Lesson 7?
By the end of this lesson, you should be able to:
- explain the requirements for meeting horizontal accuracy;
- apply the accuracy standards for different horizontal scales;
- identify sources of imprecision and error; and
- find and evaluate metadata.
