Use Google Maps Timeline data to compare with COVID-19 patient history location.

2019-ncov's Issues

automation-of-contagion-vigilance

It is possible to both track infectious agents and measure the effect on behavior with a Privacy by Design app.
The false positive problem is reduced because the proximity data is generated by the phones communicating directly with each other.
I published a paper showing how to deal with inapparent infection over twenty years ago:

Stodolsky, D. S. (1997). Automation of Contagion Vigilance. Methods of Information in Medicine, 36(3), 220-232.

A small study showed acceptability of the approach:

After a half a dozen attempts to get funding, I gave up on the idea of a contagion management test. After the #MeToo media explosion, I decided that I might pursue a test by focussing on the frontend of the design. A successful workshop led nowhere. I continue to seek an alternative strategy for funding this research.

Android Sometimes Cannot Save Files

Platform: Android (either Chrome browser or the browser in Facebook App). Didn't test on iOS (iPhone/iPad) yet.

Way to reproduce: clicking 'Download' button in step 2

Expect behavior: downloading KML files.

Actual behavior: launching Google Maps Timeline instead. Sometimes a few files can be downloaded, but not all files.

Frequency: can be reproduced easily.

Analysis: I guess there exists race condition that while the Javascript is opening KML links to download, the Android App Link mechanism is also triggered in parallel. That's why some files got chances to download sometimes.

Point in polygon

We should consider this: https://github.com/substack/point-in-polygon to handle footprints in a large area.

Flutter App TODO List

• Check against patient data
  • Define server side API (could be static file(s))
  • Fetch patient data from server
  • Parse patient data
  • Compare patient data with local data
• Export collected locations
  • Export decrypted database
  • Export encrypted database (do we need this? are there any use cases?)
• Polish UI
  • Ask again before deleting database

Process terminates with error: Parser is undefined

Steps to reproduce

1. visit https://yjlou.github.io/2019-nCov/?hl=zh-TW#
2. go to step 3 and choose any XML from google
3. open Devtool console
4. click next to go to step 4

Expected

Processed result

Actual

Process silently stopped and error is emitted in Devtool console.

Historical location data download issue

Description

When you choose the history range in step 2, it will not actually download the historical data of that period, but only the data of that day.

Expected behavior

I chose the last three days as the period, I should get below files:

• history-2020-02-28.kml
• history-2020-02-29.kml
• history-2020-03-01.kml

Actual behavior

I chose the last three days as the period, but I only get one files:

• history-2020-02-28.kml

Broken readme link (504 Gateway Time-out)

The readme link (https://ppt.cc/fgrRBx) is broken. I'm not sure where the link is supposed to point. Anyone?

Broken repo link

I just found that the link of this repo (https://pandemic.events) is broken. According to this commit, maybe it should also be changed from https://pandemic.events to https://yjlou.github.io/2019-nCov/?

KML file downloaded contains only a fragment of locations in history

Hello, when downloading the kml file i noticed that it's a lot smaller, so i parsed it and it got 340 locations for me, when here i get thousands.

Selecting period is not working on mobile

Reproduce:

• On chrome browser (PC), open dev console, and enable "device toolbar" to simulate a phone device.
• Go to step 2, try to select a different period (e.g. "Today"), and it won't work.

Support multi-language data

Try to support multi-language name / description, e.g.

{
  "name": {
    "zh-TW": "雲林東勢開安宮",
    "en-US": "Kai’an Temple"
  },
  "
}

When "name" is just a string, then we would just use it.
When current locale is not in "name", we can fallback to "en-US".
