課程概述

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!

Nick Santos is fantastic and I learned a lot in this course. However, my qualms are with coursera and the structure of the peer review assignment. I think I deserved full points on the final project (one reviewer did in fact award me full points) but the other reviewer graded harshly and plainly graded wrong, without any reason as to why they marked me down. Their comment was "good". Its like they did not even look at my project. There needs to be better quality monitoring in the grading for this course because its very discouraging and frankly infuriating that this happened.

Well structured but as with the previous course in this specialization there is way too much focus on ArcGIS. The course is called "GIS Data Formats, Design and Quality," not "Processing Data in ArcGIS." The module on ArcGIS Online is just unnecessary. There is nothing to be learned in that module that can be applied outside of an ArcGIS context.

Major lack in instructor support but a decent intro to GIS. Also, some clunks in hw instructions that slow things down. The first lecture should be on getting your student license bc it takes a few days to receive.

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.
