Proofreading this lesson and submitting feedback:
"Vector data structures represent specific geometric features on the Earth's surface, and assign attributes to those features which are displayed as points, lines or polygons."

I realize this is covered in the Introduction to Vector Data lesson in detail, my suggestion was to tie these concepts to clarify the differentiation of raster vs. vector.

"The value of a pixel can be continuous (e.g. elevation) or categorical (e.g. land use) which can be identified as quantitative or qualitative data types."

I've taught upper-division Cartography and GIS and the terns qualitative vs quantitative are worth mentioning since these are terms commonly used by GIS (geospatial) professionals.
