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!

Great information and weekly assignments/lectures. The final project, at times, was very difficult and I did not receive much mentor help. It was still a doable assignment and was able to pass.

Really nice intro to working with rasters and performing calculations based on them, either to produce new rasters or in comparison with vector data.

The course needs more practice items that does not require to buy a GIS book.

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!

Scattered and lacking focus. The material is all there, but it feels like a laundry list of miscellany that didn't make it into the previous or next course in the specialisation.

The final assignment is impossible to finish since I have 10.4 version in my computer. You, as the course provider, should modify the assignment instead of asking the student to make changes. The point is that we are trying to gain some knowledge, not wasting time on solving those bugs.
