Pipestone National Monument

I took a walk on the circle trail to clear my head this evening.

Winter WMA

I started bird surveys this week, and this was my 1st site! Oddly, it’s hard to find a map of this area anywhere online, which makes me wonder if it’s the tract that’s been most recently added? I have surveyed an area off 211th street that’s marked with WMA signs. There was on-and-off rain earlier […]

How do I Classify This?

I’m going to have an output raster brick, and I have to classify it into 2 classes based on thresholds for multiple criteria. https://pro.arcgis.com/en/pro-app/help/mapping/layer-properties/data-classification-methods.htm

Super-computing

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 […]

Predicting Big Raster Stacks w/HPC

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 […]

GDAL

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 […]
