Oct. 3, 2007

Started a big map project of western NC, starting with Lidor raster data of elevation and hillshades, and adding cities, waterbodies, and points of interest, etc. I'm still having trouble with file management, and wondering if I'll ever understand computers well enough to be good at this. Anyway, I'm waiting for files to download, so I thought I'd get started on tonights blog. I took the exam before class (makeup) and feel I did pretty well. Now if I could only be so confident about my data management! And Pete just told me how to export map data and I completely spaced out on how to do it. But it's 9:30 and I'm tired of this mess, so I'm just going to upload my map, if possible, and be done with it. I say if possible, because the last time I tried to upload a raster-based image, it didn't work. But that was in Arcview. All the little dots are a city file that I haven't clipped to my region. But clips can't be performed on raster data, so I have to merge my county boundaries to create a layer file that I can perform edits on and clip layers to. That's where the whole export map data info Pete just gave me would come in handy. There's some way I can select attributes I want to keep (cities in my region) and export only those cities and automatically exclude the others. There's always next week, but I'm feeling discouraged, and wonder if it's all worth the effort. And work takes alot more out of me than I thought it would. I LIKE the work, but it certainly makes coming to class more difficult. I just wish I weren't such a computer dunce.
