QUESTION
I want to draw the map with bubbles (bubble map) on it in react project using Highcharts library.
These are my requirements:
drawing the map
showing the specific points/locations (bubbles) on the map. (we have longitude and latitude of the locations)
- so we have list of locations with : location name, longitude and latitude. we want to show these locations on the map with bubbles
This is my source code in react (class component):
...ANSWER
Answered 2021-Mar-07 at 02:33According to the documentation, Highcharts maps do not support lat / lon directly unless the proj4js library is loaded before the Highcharts maps. That's because the Highcharts maps don't use lat / lon internally, they use a scale from 0 to 1000s. So the lat / lon coordinates that you're using are probably not visible because they're off the map.

I currently have an issue in which the Leaflets mapping API is currently showing in front of my dropdown menu overlaying it and hiding it, however, does not currently stop the user from using the drop downs nor the map.
Current Page HTML
and
Current CSS (only for the map space, drop downs and the columns below the map)
ANSWER
Answered 2021-Feb-07 at 15:38SOLVED: Z indexing-
The map itself was overlaying and must have had a hidden Z index within the API, this was overlaying most things above it.
In changing the .Dropdown-content class to a higher Z index of 20 the drop down menu was able to display over the map once again.

I'm trying to create a choropleth map using folium on python and I was able to get the base map running, but when I try to add a layer with neighborhood boundaries, it does not show up on the html page. I thought maybe I had to increase the line opacity, but that doesn't seem to be it.
This is my code:

Answered 2020-Dec-08 at 01:57Since you were presented with the data of the complaint in another question, you got the GEOJSON data from here for the corresponding zip code range. As for the process, we have tabulated it by the number of zip codes and tied it to the number of occurrences.

I am trying to integrate data from CSV file with spring boot using a batch, I have a problem with the date field because it is constantly rejected regardless of the type used, here is my code:
...ANSWER
Answered 2020-Nov-20 at 16:52As the error said you are trying to assign a String value to an Instant variable.
That mean indProd.getTime() is trying to be String.
One way to fix this is to retype to String back to instant, it is maybe not the best solution but is should work.

I don't succeed in adding a final layer to my Highmaps. I have already the ground map and some additional layers. But the lake layer does not succeed to be displayed. Why is that? It does load into QGIS correctly.
Truth is, by the way, that I haven't understood the difference between calling a GeoJSON file like this (which works for my additional layers):

QUESTION
I've a fixed length content Flatfile which contains sample records like below and has no delimiter as such it contains special hex characters and data is spread across multiple lines too. But each line has constant 2000 bytes/characters and I need to keep picking the bytes from 1-2000, 2001-4000 and so on. I've fixed index characters.
Note - Here I don't want to read all characters from 2000 lines, just wanted to read based on Range.
Customer.java
...ANSWER
Answered 2020-Sep-04 at 16:55The main problem here is that FlatFileItemReader assumes you have line breaks, which you don't. The clearest solution to me is to copy/paste the class and swap out the readLine() method with one that takes in the appropriate number of characters. Unfortunately, because much of the class is private, you can't easily extend and override.
