Advanced GIS is an awesome class that allows us to learn and implement a larger tool set within ArcGIS. We learn everything from network analysis, stream networking, interpolation (below), geo-coding, and many many more.
Below is a lab that instead of making the required table in Microsoft word, I took a cartographic approach and made in Adobe Illustrator. Interpolation is the process of taking a few points and mathematically determining the space inbetween those points to create a surface similar to those you see everyday on something. There are many ways to calculate the surfaces between points which you can see above.
