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 foundation for understanding the value of data and what makes a good data set different from a bad one.

Goes over methods to classify, sort, modify, and organize data for your projects and those you share with other analysts.

Awesome course. Comprehensive content. Great lecturer. Proper labs. I like how this course does not just let you wade through learning GIS, because the technical level is high. You'll be a pro after going through all these courses

Another forward step in GIS learning, starting to use some geoprocessing tools, and understanding how the geodatabases work, and when to use each tipe. Also, great start to learn how to make your own data. Great course overall.

This class gets into the really fun topics that got me interested in GIS in the first place like raster manipulation, spatial analyst tools, editing and creating features, and all the neat things you can do with the toolbox.

Well laid outcourse with solid instruction and practice opportunities. It is definitely more rigorous than the previous course in the specialization, but should not be too difficult for anyone with familiarity with GIS.

T​his course dwells deeper into processing and analyzing vector and raster data. The course pace is good and reasonable for working adults. The exercises and assessments were also good and focused on essential topics.

Really good , clear explanations. I loved how the theory was interwoven into real life applications in the software. I really did find it really good and will re-use the material as a reference in the future.

Another great course on GIS analysis. It's a bit more in depth and helps teach you how to manipulate data a bit more. It's helpful if you deal with large datasets and need to know how to manipulate them more.

A bit more advanced than the first course in the specialization and really interesting! The final assignment allowed for a good understanding of the spatial analyst tools and the reasons behind using them.

This course helped me get a better grip on building maps and the managing of geodatabases. It made me more confident in pursuing the building of GIS maps on my own with publicly available geoinformation.

Teacher does a very nice job at explaining the subject matter. The only drawback to Coursera is that sometimes it is difficult to get anyone to answer a question about the material.
