Welcome to the DataChallenge!

[ratnanil]

Dear DataChallenge participants!

Today is the deadline for registering to the DataChallenge. I think this is a good time to welcome you all to this event, we are very much looking forward to it!

Those of you who have provided me with a signed NDA (@dinigi, @grbiuzh, @KimboGilda, @nikitakrahenbuhl, @pfaffrob, @timfaessler, @bussmman) I've sent the data via email. I'm still missing the NDA from @HerbertDaMoth (see #9) and @cewinharhar (see #5). Can you guys send me the NDA so I can provide you with the dataset?

Some of you are taking part in this challenge as part of the cource Computational Movement Analysis, with you I've talked about possible ideas you can explore with this dataset. I have not had this chance with those of you who are not part of the mentioned course. Can we schedule something for the coming week? For example on Wednesday (18.05.2020) between 7:30 and 12:00 or on Thursday (19.05.2020) after 14:00 would be great. You can simply respond to this thread if you can make it during one of those time slots.

If you have any questions, please do not hesitate to contact me..

Cheers!

Nils & Team

Hi Nils :)
Thursday (19.05.2020) after 14:00 would fit me as well!

Best

Kevin

[dinigi]

Hi Nils, I work during these times but could also take a break from work between 10am and 5pm for an online meeting.

Ok super, let's meetup on Thursday at 14.30. I'll send you an invitation with a link before the meeting. What about the others, can you join this meetup as well? Since I'll be gone from the 23rd May to the 5th of June, I think it's important that we meet up this week, so you can get started with exploring the data!

Additionally, it's very important to start organizing with your respective "Studiengangsleitung" to make sure you earn that ECTS, those of you who are interested in this. Who is interested in earning an ECTS?

[pfaffrob]

Hi Nils

Yes, I'll be available on Thursday as well. I'm also interested in earning a credit.

[bussmman]

Hi Nils

Sorry, for the late reply, I was super busy the past few days. If it's okay, I will also join the meeting this afternoon. I do not need an ECTS.
Cheers Manuel

[dinigi]

Great, I'll get in touch with my Studienberaterin regarding the credit. Cheers

Here are the details on the meeting tomorrow!

• https://zhaw.zoom.us/j/62991105798
• Meeting ID: 629 9110 5798
• via Skype: https://zhaw.zoom.us/skype/62991105798

I had a chance to talk with some of you yesterday afternoon. Here is a summary of what we discussed:

• You can find the data for the Challenge as well as for the Hackdays here
  • This is a "private" repo to which I have unlocked everyone who sent me back the NDA.
  • You can find some infos about this dataset here: https://datachallenge-n.github.io/data.
  • I will inform you via GitHub if there are any changes to the data (enrichment with metadata, removal of incorrect values etc.).
• The first step would be to explore this data with a tool of your choice (R, Python, QGIS, ArcGIS...). It may make sense to initially focus on only one individual during a short time period
• After a first exploration, you can follow your own ideas and start to pursue concrete goals for the DataChallenge. Many things are conceivable in this process: You can visualize the data in interesting ways, look for exciting patterns (e.g. seasonal or spatial), create an animation, or work more with statistics and machine learning. The choice is yours!
• By June 10, submit the current status of your result by posting the link to it in your respective GitHub Issue. Ideally, the link itself is a GitHub repo (for those who are familiar with GitHub), or you post the link to a GoogleDocs (or similar) document.
• From the 20th - 22nd of June we will work together on your ideas. Here you have the possibility to form new groups or to pursue your own idea.

Please do not hesitate to contact us if you have any questions about the data or the DataChallenge itself. I will be away for two weeks as of now, you can contact Nikos during this time or schedule an appointment with him directly. In two weeks, you can contact me again or schedule an appointment.

A friendly reminder that your submission to the DataChallange is due this friday (see #12 (comment)). I haven't received any questions from you, so I'm hoping that all is fine. If have any questions, contact me or Nikos or schedule an appointment with Nikos or with me directly.

Also: remember the Hackdays are in two weeks (20 - 22nd June)!

Cheers,

Nils

Hey Nils

I'm exploring the data using R and used rgdal to load a shapefile into the project. I now want to proceed and count how many of the points lie within the polygons of the shapefile. Whats the easiest way to do this?

Greetings,
Robin

[ratnanil]

@KimboGilda: Since I'm not in the office tomorrow, can you answer this?

sure!

@pfaffrob
Hallo Robin,

a quite simple way to find the points that lie within a polygon is by using the concept of intersection. Below I have an example I wrote on how you can perform a similar operation:

library(sf)
library(dplyr)
library(ggplot2)
library(readr)

## Reading the shapefiles
pol <- read_sf("dummy_data/dummy_polyg.shp")
points <- read_sf("dummy_data/dummy_points.shp")

## Plotting
ggplot() + geom_sf(data = pol, alpha = 0.2, fill = "green") + 
  geom_sf(data = points, color = "blue", alpha = 0.4)

# Intersection between polygon and points

intersected_points <- st_intersection(x = pol, y = points)
ggplot() + geom_sf(data = pol, alpha = 0.2, fill = "green") + 
  geom_sf(data = points, color = "blue", alpha = 0.4) + 
  geom_sf(data = intersected_points, color = "red")

Have a look and hopefully you can find it useful

Dear all

We will meet on Monday at 9:00 in GA219. Since we are a small group, we will look adhoc on how we should spend the three hackdays, since we can consider each of your timeschedule. Can you confirm if you can come at 9 to GA219 by replying to this post?

Looking forward to hacking!

Nils

[nikitakrahenbuhl]

Works for me

[bussmman]

Like I said, I unfortunately won't be able to physically make it to Wädenswil on monday. I will only be able to join on Wednesday

[dinigi]

Yes, see you on monday
