GIS for Transportation: Principles, Data and Applications

2.6 Summary of Lesson 2

PrintPrint

In this lesson, we discussed the importance of roadway centerline data to GIS and explored some of the public and commercial sources for this data. In particular, we took a close look at the Census Bureau’s TIGER data which we will get to use in upcoming lessons.

Our transportation organization of the week was the Census Bureau. We spent some time learning about the geometries the Census Bureau uses to organize and aggregate the data it collects via the decennial surveys and the ACS. We also took a look at the CTPP and how Census Bureau data is used for transportation planning.

In our weekly webinar, we had the opportunity to interact with Doug Tomlinson, an expert in ITS. In preparation for next week’s webinar, we reviewed the role of Section 106 of NHPA in transportation projects and explored a cultural resources GIS application.

Finally, you had the opportunity to learn a little bit about your classmates by reviewing their video autobiographies.
