Preliminary BWA infestation modeling
Introduction With the preliminary infestation scoring done, it’s now time to explore some predictive modeling. My go-to modeling tool is random forest, so I think that’s a suitable place to start. We can test out alternative modeling tools in the future, but RF is pretty robust. This will be a considerably shorter, though hopefully considerab...

BWA Field Plot Infestation Scoring
Introduction I thought I would put together an R Markdown document as a convenient way to start sharing my work on the preliminary field data for the BWA project. My goal here to be transparent about how I’m conducting various components of the analysis, and share the raw(-ish) code with you so you can take a look, comment, make suggestions, et...

LF Data Acquisition and Summarization
Acquiring the data Navigate to https://landfire.gov/ Select Get Data Select Data Distribution site (DDS) Click on the map in the approximate area you plan to download data (this step doesn’t really matter – the DDS has a dynamic, navigable map where you will zoom/pan to your area of interest) In the DDS, click the Download Tool button Select...

BWA-FIA data exploration
Introduction While fully recognizing (and appreciating!) the fact that Erin is the FIA expert, and will be doing most of the meaningful work with FIA data, I thought I’d do some quick exploratory work to, at the very least, start to nail down the extent within which we are interested in grabbing FIA plot data. Plus, it’s an excuse for me to g...

NPV spectral indices
I wanted to share some code with both of you before I moved forward with the actual model runs to make sure this aligns with your expectations. I’m just going to create a simple fake dataset with three bands and associated reflectance values, the middle of which will represent an absorption. I’ll calculate three three-band spectral indices, a...
