In case anyone is interested, I've been trying to use turf.js on both Mapbox and Mapzen vector tiles, and I've learned a few things I wish I'd known going in.

Background

This thing I've been working on for a month or so here and there, to make maps like this:

Purpose

david-murr

 fio cat ../missed.shp | rio zonalstats -r amfam.vrt --categorical | jq '.features[].properties | {APN: .APN,pool: ._1}' | jq --slurp . | in2csv -f json > test.csv
 
jq '.features[].properties | {APN: .APN,pool: ._1}' pools.geojson | jq --slurp . | in2csv -f json > test.csv

fio cat countries.shp | rio zonalstats -r dem.tif --prefix "elevation_" > countries_with_elevation.geojson
fio cat large.shp | rio zonalstats -r elevation.tif --sequence | some-other-process
time fio cat ../parcels/parcels_pools.shp | parallel --pipe "rio zonalstats -r amfam.vrt --categorical" > out

fio cat test.shp | jq '{geometry: .geometry, PARCEL_ID: .properties.PARCEL_ID}' -c | fio collect > test.geojson

Finessing Excel's stupid line endings

I am sheepish to admit a certain type of routine Microsoft Excel use.

Current example: I am marking for STAT 545. I use R to create a comma delimited marking sheet, by joining the official class list and peer reviews. The sheet contains variables, initially set to NA, where the TAs and I enter official marks and optional comments.

This is where Excel comes in. I like its visual organization of this comma delimited file much more than, say, using a plain text editor. I use the ability to hide columns, resize columns, wrap text, and (gasp!) even fill rows with grey to indicate I am done.

I keep saving the file as comma delimited and I put up with Excel's incessant freak out about "losing features". This is not a one time thing. I need to save and commit this file many times before it is considered done.

#!/bin/bash
# rename TMS tiles to the XYZ schema
# no quoting, since all files have simple numeric names
# do not run this anywhere else than INSIDE your tiles directory

# run it like this: find . -name "*.png" -exec ./tms2xyz.sh {} \;

filename=$1

tmp=${filename#*/}     # remove to first /
