課程信息

In this course, the second in the Geographic Information Systems (GIS) Specialization, you will go in-depth with common data types (such as raster and vector data), structures, quality and storage during four week-long modules: Week 1: Learn about data models and formats, including a full understanding of vector data and raster concepts. You will also learn about the implications of a data’s scale and how to load layers from web services. Week 2: Create a vector data model by using vector attribute tables, writing query strings, defining queries, and adding and calculating fields. You'll also learn how to create new data through the process of digitizing and you'll use the built-in Editor tools in ArcGIS. Week 3: Learn about common data storage mechanisms within GIS, including geodatabases and shapefiles. Learn how to choose between them for your projects and how to optimize them for speed and size. You'll also work with rasters for the first time, using digital elevation models and creating slope and distance analysis products. Week 4: Explore datasets and assess them for quality and uncertainty. You will also learn how to bring your maps and data to the Internet and create web maps quickly with ArcGIS Online. Take GIS Data Formats, Design and Quality as a standalone course or as part of the Geographic Information Systems (GIS) Specialization. You should have equivalent experience to completing the first course in this specialization, Fundamentals of GIS, before taking this course. By completing the second class in the Specialization you will gain the skills needed to succeed in the full program....

Great course. Quite challenging, huge amount of info shared and employed in the assignments. This makes the course very thorough yet as mentioned, challenging to complete. Not for the faint at heart!

Solid content. Pace is faster than in the Intro course (1st course in specialization). The final project was challenging and rewarding.

Very informative course. Some concepts are not easy to understand at the first glance, but it is always interesting to learn and apply in the projects. The final assignment made me frustrated in the beginning. But as soon as getting the whole and clear picture of the project, it was fun to apply the knowledge into the real project, and designed our own workflow. The videos explained explicitly some core concepts which were very helpful and I found myself revisiting many times again when doing the project. Forum was helpful as well. I learned and got clarified some problems there many times. Overall it was a great course for anyone who wants to dig into GIS more!
