I'm looking forward to my field trip this morning to the study area of this semester's GIS project - Coulee Baton. It's north of Kaplan and Abbeville. I have been downloading the DEMs and contours for the area, trying to get them to look right because the study area comprises 4 quads.
Still studying up on terrain and watershed analysis possibilities in ArcMap. As suspected, those algorithms work much better on very hilly terrain than the flatness of my study area.

Next Thing
Jim would like an aerial photo map of the Bayou Sorrel indian mound. He showed me where it was on one of his maps; now I need to find the right DOQQ.
We'll see!
We'll see!

Getting It Together


Since the husband flew off to Canada last weekend, I've been trying to get back to working on my "summer school" project. It is an expansion of last spring's class project.
Got everything going, overcame some squirrely ArcView issues, and it's coming along.
I've got some modern DOQQs of the area, some scanned 1:250,000 topo maps (which unfortunately split the study area horizontally right about in the middle), and some historic 15 minute quads. Got them clipped down; they fit together pretty well. However, the colors and symbology is not consistent across the quads so they don't look very smooth.
We'll see what Jim needs to show on his Powerpoint later this afternoon, decide what will fit.

Oops - Can't Work on GIS Today
Got a call this morning to go into work - I will probably have another day off later this week to catch up on my GIS project. Can't do it today till later.

Need To Get Back to Work
I have taken a few days off this project; I need to get the next phase completed. Tomorrow and Monday should give me a chance to make some progress.

Moving Right Along
I have clipped and combined the 9 quads that are needed to show Jim's study area. Next step, create the line and point layers.

The Work Continues
Jim Delahoussaye is giving a presentation at Vermilionville for their lecture series in mid-July. I'm working on expanding my class project to give him some maps he can use in the slide show about the Myette Point people.
I don't know why I couldn't figure out this feature of ArcMap last semester; I guess I was so panicked by the end of the semester that I wasn't paying attention.
Anyway, I had previously used clipping in last fall's class, and while revisiting it a few days ago, I found that it is possible to clip a base map to the extent of a layer. This will effectively clip the map collars of the historic quads I'm using, and provide a nearly mosaicked map. I think I have all the quads of the study area in the 1935 edition, so I'm getting excited about working on it.
