Now What?
Thanks, but that was a lot more confusing than I thought it would be!
Why don’t I just get a DMTI census file from UT? I’ve heard they are easy to use…

Oh.
Yikes!

Wow.
I need a moment…
![Page 14: Would a GPS Help?](https://reader036.vdocuments.us/reader036/viewer/2022070410/5681469a550346895db3b37c/html5/thumbnails/14.jpg)
Okay, Tell Me More…
DMTI+ Project files (.apr)
available; ArcView-ready+ Individual files come as
shape, no need for importing
+ 96 Census boundaries are paired with Census tables in .dbf format, ready for joining to spatial files
- Bundling is still a “challenge”
Alternative route: IDLS
STC+ STC spatial data
only; census geo rocks!
+ STC Documentation is at your fingertips
- Organization still chaotic
- Tables still have to be tweaked before merging

Is It Worth It?
You bet!
It gives research an entirely new dimension and, though there is new language, you still have two feet on the ground at all times.
We promise!

Making a Sandwich
Where in the world are we and is that really PB over
there?

GIS is really about…
Where…What…

Location:
e.g. Latitude & longitude

Sounds Simple! Let’s Go!

missy!”

“What” can be any spatially-referenced entity or phenomena.
This means that a project can get out of control very quickly….
Why You Want More Lessons
Especially if you don’t use the standard or compatible scale, data
and projection in your project.

Why You Want More Lessons
Imagine a sandwich in which everything imaginable including drano was added in random order, dropped at heights varying from two inches to 30,000 feet (yuck, the pickle just came through the roof and onto the kitchen table---sort of), the mayo ended up in the living room and the bread in the backyard, and the chicken—well someone forgot to cook it.

So Start Gently!
Your first map doesn’t have to be that kind of disaster.
We’re going to take a look at one concept today—layers or themes of a map. It is a great concept to see in action and will really help with the reference questions you get!
