QUESTION
I would like to insert the JSON data into MySQL database in the very obvious way as given an example in the picture. Picture shows the same data, but outputed in CSV format and that's how exactly I want it to be in MySQL.
I have prepared the database and the query for inserting, however I can't figure out the code to find right array key or value

QUESTION
I am attempting to plot a Choropleth using plotly and geojson data. While I am able to plot the base map using mapbox, the colored polygons used to represent spatial data is missing.
Here's the code:
...ANSWER
Answered 2022-Feb-28 at 14:14As I understand it, the example in the official reference uses FIPS, so no fueatureidkey is needed, but if you use a different geojson, you need to set up a key that associates the geojson with the user data. We have not verified to the content of the polygon information, but we have confirmed that a specific region is depicted when the map is zoomed in.

Angularjs-Material v. 1.2.4
Both issue can be reproduced using this demo sample: https://jsfiddle.net/Drasius/z51vgqr6/27/
Angularjs-Material md-datepicker when using ng-model-options="{timezone: 'UTC'}" option input box shows date in local time and Date Picker calendar in UTC time. There is jsfiddle script with the issue https://jsfiddle.net/Drasius/z51vgqr6/11/

Answered 2022-Feb-22 at 10:31There was issues with angular-material. Created isssue in angular-material github: https://github.com/angular/material/issues/12149.
- some changes was required to my application.
Sadly the lib is end of life and no plans to release new version so forged repo and fixed the issue, you can find fix in this repository https://github.com/vdrasutis/material. So in app instead provided angular package from bower - included my own local copy of angular-material script with my fix.

I am trying to find recent news that were published within the last 2 hours.
ApproachMy goal is to take a datetime
object of today and compare it to a date of an article which I scraped from the web.
First I compare the datetime by date and then by hour.
IssueHowever it seems that even when given a correct date it says it isn't in the correct range.
False fail:
Code ...ANSWER
Answered 2022-Jan-25 at 00:28See how I reduced your given code to a minimal reproducible example with a few steps:
- remove the web-scraping (as not essential for the issue)
- remove all the comments that do not explain
- remove empty lines that do not help to structure
- (optionally) add a test (e.g. a function-call) that shows the issue
Since you claimed issue with datetime comparison I found one inconsistency:
In day comparison you have:
QUESTION
Using this question: 3D point rotation algorithm I was able to assimilate a basic rotate function for my arbitrary vector library in javascript.
The issue is, the question above doesn't explain how to rotate around any point (Like an orbit)
This vector library extends the Array object type (I originally forked it from an old project, and then adapted it for my own projects), so think of each vector like an array with extra methods and getters (You can find the whole source code here)
This is the method I use to rotate the current vector with a Vector plugged in as the angle (So each axis can be controlled separately)
It grabs the cosine and sine values required for all three axi (pitch, roll, yaw) and then stores them as three vectors in an array.
Finally it multiplies each vector into each coordinate accordingly.

and want to rotate a vector v
around a point a
, then the formula for the result is

I'm using this dataset: https://sedac.ciesin.columbia.edu/data/set/gpw-v4-population-density-rev11/data-download (Gridded population density of the world)
With this map: https://data.humdata.org/dataset/uganda-administrative-boundaries-as-of-17-08-2018 (Uganda administrative boundaries shapefile)
I have clipped the uganda map to the region I need, like so:
...ANSWER
Answered 2021-Nov-18 at 22:19The problem is the shapefile is in UTM coordinates and the raster is a world coordinate system (lat/long). Even though you assign the epsg:4326
crs to gdf
it's coordinates are still in UTM. You can convert these manually doing something like this.
Otherwise, you can re-projected the world raster into EPSG:21096
(estimation based off UTM zone from the uganda shapefile) using QGIS or you can use gdalwarp.
After changing the projection on the raster the rest of your code worked.

Answered 2021-Nov-15 at 10:54The problem with your code is that you need to define the bbox for the crop filter using the same CRS as the world3
