Module 6- Introduction to GIS- Georeferencing

     This week’s lab focused on georeferencing and working with rasters. We made two map layouts. For the first map we used the georeferencing pane to practice georeferencing two rasters of the UWF campus and a historic picture onto the road and building layers we had already added. We would mark points on our unreferenced map and match them to points on our referenced data layers. It was interesting to see the map adjust and resize itself between each point. We digitized a building and a road onto one of the images. I found the building difficult to digitize and think that is something I can work on improving. We then built a multi-ring buffer to show the bald eagle's nest easement located on campus.

    For the second part we turned our first map into a 3D scene. I found working with the rasters to make a map layout more frustrating than previous maps, some of the options that were available to me were not available in raster format. In particular, I had trouble with labels. I wanted to label my North Campus and South Campus rasters in my first map but ended up adding a text box instead of a traditional label. I also ran into trouble with labeling the 3D scene, I was trying to offset labels on my 3D buildings and road but this option was whited out and not available in 3D format. I also struggled to get my roads to label until I moved them up into the 3D pane. It seems like working with 3D and 2D data in the same map layout caused complications.

     Now that I have established some of the basics of creating a map I find myself interested in learning ways to make a map visually appealing. I spend so much time on completing the labs and learning the fundamentals that I haven't had a lot of extra time to study well made maps and I'll admit it wasn't something I did too often before taking this course. Hopefully I can find some time between semesters to dig into this topic some more.

GIS Portfolio

 We were tasked to create a GIS portfolio for our internship program. It was a great opportunity to put organize the work I have been doing....
