See below; version 2.4.2 from the ubuntugis ppa.

Expected output is just the version information, no crash.

$ gdal2tiles.py --version
GDAL 2.4.2, released 2019/06/28
Traceback (most recent call last):

Is there a way to know when the imagery was collected? I assume sometime in the daylight hours, and probably recently(?) but I have no way of knowing by looking at the output and the associated image.

Can that output be put in the CLI output or some other metadata file that gets associated with the LC####### directory?

A small thing, and not very important, but it seems redundant to end every episodes title with "in R" since the name of the lesson is "Introduction to Geospatial Raster and Vector Data with R" and all the episodes use R. Furthermore, there are three episodes that don't say "in R" that do in fact use R....

Expected behavior and actual behavior

Cropping any raster with any GeoVector should work. Instead, if the GeoVector is bigger than the world, an error is raised.

simple_world.geojson.zip

Steps to reproduce the probl

Investigate how to build a .deb installer.

Lines L315:L325 in Lesson 5 advocate for subsetting columns without comma notation:

head(gapminder[3])

I'd argue that for clarity sake, we should change this to always use comma notation:

head(gapminder[,3]

It would be very useful to create a template for the schedule of a geospatial workshop to be used in the workshop website. This schedule should be added to this file: https://github.com/carpentries/workshop-template/blob/gh-pages/_includes/dc/schedule.html
