M6 Georeferencing, Editing, & 3D

 

    This week's lab had us put many of our skills from the course to good use, with one such skill being utilizing the multiple ring buffer around an eagle's nest in accordance with FWC requirements for space. We also learned a very valuable skill that is georeferencing, to place raster images together as well as to fit somewhat properly on top of a base layer image. One of the last skills we used was digitizing to help create a building and road feature labeled on the map above. 

    The big take away from this lesson had to be the georeferencing procedures used to locate the images properly on the basemap. We used control points in the georeferencing tab to find obvious geographic similarities, like the corner of a parking lot or corner of a building, to help align and scale the aerial imagery to the map beneath it. We learned about the transformations involved, the amount of control points needed for the transformation to be effective, and how having a low RMS error isn't necessarily better. Having a low RMS error without sacrificing the appearance to distortion are equally important. 

    Ultimately this lab was great, but I found myself without time to complete the optional lesson. Maybe later this week I can hop in and see what I'm missing out on!
