Advance GIS and Mapping .

About this Course

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 modules:
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.
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 QGIS .From Data Management features to Cartography and Spatial Analysis capabilities, as well as spatial infrastructure with QGIS Server.

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.

You should have equivalent experience to completing the first course Introduction to mapping using QGIS 3X before taking this course.

By completing the second class in the Specialization you will gain the skills needed to succeed in the full program.
