Querying Data, Joining and Relating Tables

Querying data was familiar since I have done this before in other programs. Creating reports likewise. Just need to go over the steps again to feel really comfortable with it in the ERSI software. When I was completing the Bent Creek Map, I was curious to see the trail info more organized so I created reports and queryed the data for the fun of it. I was surprised to see that their were so few hike only trails. The two short hike only trails are connectors and it doesn't make sense why these were designated so. I'll have to check out the trails to see if their is a good reason why. The Bolstad chp. on this really was a hard read. I completed and saved the listing in ex. C, but could not get the doc. to open. Although it shows as I saved it, I could not open to load to Blog.

Chp 9 exercises are great examples of the environmental / natural resource use a GIS. Having the ability to compile info from various sources, relate or join the sources, really drives home one aspect of the useful complexity of the software in analysis of such large regional issues.
