Sobre o curso

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!

The course is very good, but I did find that I had problems with some subjects that were not covered well enough to be able to work out the outcome required. I push myself hard anyway, so pretty happy to get through when I know I could have done better. Thanks again Nick, I will start the 3rd course, once I am happy my computer has all the components I need for ArcGIS to run without wanting files from my other computer. Have a great day.

Great course! Compared to the first course of this GIS specialization (Fundamentals of GIS), this 2nd course has a few minor gaps in the lecture notes/videos. However, some exploration and practice, as well as other readings do help with overall understanding and with completing the assignments successfully.

Thanks very much!

Peer Review system needs an overhaul. I would suggest increasing the number of reviews required by each student so you one incorrect (based on user error) review does not influence your grade so significantly.

Otherwise, this is an informative and useful course.

I would have given it 5 stars, but Tutorial Assignment 3 was written as though it was pulled from another course without editing, and contained references to file paths and names that didn't match the reality of the course and required some deduction to sort out.
