Today we had lectures on Chapter 4 and chapter 7.
Chapter 4 is about Data Entry. Data Entry is the most expensive and time consuming of GIS. Also Data Entry involves taking infomation from maps and using it effectively. If the information is 
incorrect the GIS project is worthless.
Chapter 7 is about Digital Data Sources. There is a 3 step process Identify, obtain, and ingest. Digital data sources are web delivered from government sources and a lesser extent private sources. Spatial data formats/datafiles are Coverage, shapefile, and geodatabase.
We also done two chapters in lab today. Chapter 15 and 16.
