Add `web_cache` folder with data read on-the-fly

Dbscan video is not available Module - H(Points)

The dbscan video is not available under the course page https://darribas.org/gds_course/content/bH/concepts_H.html .

The video in the private mode as seen on the youtube.

I've seen there's an alternate video link:

DBSCAN: Density-Based Spatial Clustering of Applications with Noise

Better to update the youtube id in the notebook with 9itCLrUNy94

Add package `make`rs

problem when installing the jl_setup.bat

Good Afternoon Dr. Arribas-Bel,

My Name is Florencia, I am a Geologist.
Excuse me for bothering you but I am currently working on my Phd doing a morphometric analysis base on Dems using QGIS and I would like to use your gds_env for spatial autocorrelation, as I saw you explain in the gds Course (ENVS363/563). But I am facing a problem when installing the jl_setup.bat and I cannot run any of the codes described on the course.

I have been stuck at this point for a couple of months and I am not being able to find a solution to the problem. I will sincerely appreciate your help a lot.

First I've followed all the steps to install the software for Windows 7, as described on https://gdsl-
ul.github.io/soft_install/otherWin.html
I was able to install Anaconda and GDS environment successfully but when I tried to run the jl_setup.bat script on the Anaconda Prompt the message 1 appears (I attached it as a photo) and when I tried it again message 2 appears
(I attached it as a photo).

I really don't know what else to do or to try in order to install the script successfully so that I can perform spatial autocorrelation for my morphometric analysis using your platform. Sincerely I will appreciate your help a lot.

Kind regards,
Florencia

Update Binder to `gds:6.1`

Change City ID

In Lab C (Cell 30 - I think), change pt2 = cents[112] to pt2 = cents[12]

Number of neighbours wrong

In https://darribas.org/gds_course/content/bF/lab_F.html we see:

"Now, because we have row-standardize them, the weight given to each of the four neighbors is 0.33 which, all together, sum up to one."

Should the "four" be "three"?

And while I'm here it should be "because we have row-standardized them" (missing d), and "neighbours" if you are going for British English!

Different slope in manual Moran's plot and moran_scatterplot(mi)

In Lab F (https://github.com/darribas/gds_course/blob/master/content/bF/lab_F.ipynb) there is a Moran Plot created using the standardised variables of Pct_leave. When we calculate Moran's I without using the standardised variables, we get a value of 0.62. Running moran_scatterplot(mi) gives a different (steeper) slope than the first Moran Plot with the standardised variables. It also seems that even if we were to use the standardised variables when creating mi, we don't get the same slope as the first plot we created manually.

As a suggestion: Clarify that the value of 0.62 refers to the slope as seen in moran_scatterplot(mi), or perhaps explain why they the slopes in the figures differ.

Again, thank you so much for your wonderful work!

Typo on Block G

From a ENVS3/563 student:

I have some doubts about the G Block and the K-mean in the book.
Because the size bar doesn't seem to match its explanation, I thought I might have misunderstood something.
Does anybody know why this part can get the result? Thank you!

pois_from_place

Cell 5 in Lab C. I have changed cell 5 from pois_from_place() to geometries_from_place(), however, I get the following error: "module 'osmnx' has no attribute 'geometries_from_place'.

I presume this is due to the version of the OSMNX library on the GDS Stack 5.1 on university system. The OSMNX version on the GDS Stack is 0.15.1

Fix bibliography

References are not currently being picked up. This might be related to being built on an older version of Jupyter book?
