So apparently… “…Bootstrapping and Markov Chain Monte Carlo, can be [sped] up significantly by using several connected computers in parallel.” – snow simplified Looks like I missed the boat on model fitting. Currently, I’m trying to use a MPI cluster implemented via snow (technically, clusterR). Here’s my latest error: Child job 2 terminated normally, but […]

Today I had training for the impending field season.

The bird of the week is Henslow’s sparrow!

I revived my Twitter game this spring, and the bird of the week is lark sparrow! Since I’ve been gone (from the #scicommgames scene) here are the the birds we’ve played… hairy woodpecker European goldfinch northern saw-whet owl eastern meadowlark brown-headed cowbird

Here’s the latest of what I’m working on… Fitting models to predict FIA metrics from summarized LiDAR variables separate models for each NPC system boral Validating those models Using those models to predict the values of FIA metrics across the state The last objective, given the fine scale of summarized LiDAR data and the broad […]

Here are some examples of masks I’ve made, keeping values within certain ranges. Then, I get rid of all the other values. gdal_calc.py -A combine_rcls.tif –outfile=result.tif –calc=”1*((A<=119)&(A>=44))” –NoDataValue=0 gdal_calc.py -A result.tif –outfile=FPWF.tif –calc=”1*((A<=54)|(A>=111))” –NoDataValue=0 gdal_calc.py -A combine_rcls.tif –outfile=FD.tif –calc=”1*((A<=37)&(A>=19))” –NoDataValue=0 gdal_calc.py -A combine_rcls.tif –outfile=MH.tif –calc=”1*((A<=77)&(A>=61))” –NoDataValue= This leaves only 1’s where the desired pixel values […]

Today we walked Loveland Rd. for a little ways past Drew’s Landing. A ruffed grouse was in the open alongside the road, so we paused. We were stoked when it strutted out into the road and showed off its namesake ruff! It also flared its tail and strutted around for a bit, before retreating into […]

There’s a cluster function in the raster package! https://www.gis-blog.com/increasing-the-speed-of-raster-processing-with-r-part-23-parallelisation/ https://www.gis-blog.com/increasing-the-speed-of-raster-processing-with-r-part-33-cluster/ http://r-sig-geo.2731867.n2.nabble.com/Re-Parallel-predict-now-in-spatial-tools-td7586048.html http://www.timassal.com/?p=1920

This evening, I walked a trail in Douglas Co. and heard a barred owl in a different spot than my 1st detection. I heard the owl in the woods beyond the clear cut. It could be the same owl as before! If so, I made a hypothetical home range. I wasn’t sure how far into the […]

I realized when I became slightly uncomfortable asking myself “why lifers,” I had to blog it out! I’ll start with what to me is the personal elephant in the room: using fossil fuel to see a new species, alongside the potential disruption to the bird. If I’m honest, I feel the contradiction of releasing more […]
