I have been trying to get stellarium-web running (https://github.com/Stellarium/stellarium-web-engine).
With a clean Ubuntu 18.04 install, after installing scons and emscripten the "make js" command still fails, with some (at least for me) unreadable error as seen below:

QUESTION
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.
QUESTION
I have been trying the whole evening to produce a map using a given link. However, I could not figure out what the problem was. I am using python notebook and would like to produce the map of San Francisco using GeoJSON.
I have been given the following link: https://cocl.us/sanfran_geojson and then I tried to read it into my machine using
!wget --quiet https://cocl.us/sanfran_geojson -o sanfran_geojson.json but I was not successful.
Further I am going to use the following:
sanfran_geo = r'sanfran_geojson # geojson file
sanfran_map = folium.Map(location=[0, 0], zoom_start=12, tiles='Mapbox Bright')
sanfran_map
ANSWER
Answered 2020-Oct-25 at 13:15I assume your main problem is related to the fact that you're running your jupyter notebook in Windows and wget utility is not available in your system.
The most direct way to workaround without actually installing wget for windows is using a Python http client, for example, urlib.request.
I've noted by the legend of your choropleth map that you're using another dataset (Canada Immigration), so make sure you change pandas Dataframe and the column names you provide in the data and columns parameters of your choropleth map.
Assuming you're using python 3.x:
QUESTION
I solved this during the writing of the question and have provided my answer below since it was a bit tricky to work out. I am happy to hear any better or alternative answers.
I have an Angular OpenLayers 6 geomapping app. Being Angular I use Typescript and it transpiles and runs fine. And also being Angular it uses ng test to do the testing. All tests run fine.
However I use mocha + chai for testing in the IDE (IntelliJ) since I don't require UI testing for the mathematical work I'm currently performing (ng test runs the UI tests if and when I need that. But in the IDE I select the tests to run). Testing this way worked fine until I added a new test that creates a new instance of a class that imports GeoJSON:
ANSWER
Answered 2020-Jan-31 at 09:08The answer is to add --require esm --require jsdom-global/register to the node / mocha call.
The esm is to specify ES6 as the module format and jsdom-global is to define the DOM in non-browser environments (specifically to define document).

Ok, another (small, I guess) issue with osmtogeojson... So basically I need to download data from openstreetmap through Overpass API, but in geojson format. I'm not very used to HTTPS requests and responses, so I guess I missed something between this and the use of osmtogeojson, as I get this :

QUESTION
I am working on an openlayers map to add a vector layer with the source of the local geojson and gpx file in a Vuejs project, but the vector layer cannot be displayed. I tested outside of Vue.js and I have the same problem.
Voici le code :
...ANSWER
Answered 2019-Dec-24 at 11:50Just copy the data folder and inside files into dist folder.
This problem happens because your application can't find the data folder. npm run start serve your application build (dist folder) on localhost:1234. The question is "Is there any data folder in localhost:1234 ?" or "Can I access my data via localhost:1234/data ?".
To solve this problem as mention above you need to copy the whole data folder into the dist folder.
QUESTION
Following exactly the example of the openlayers site in:
https://openlayers.org/en/latest/examples/box-selection.html?q=feature
Locally I have the following error:
...ANSWER
Answered 2019-Nov-18 at 19:11I found the solution.
In the process of developing an application in OpenLayers, unfortunately there are problems loading files locally (geojson, png etc.) due to CORS.
An excellent text on the subject here.
To solve the problem, I used the Chrome extension called "moesif CORS extension".
With it enabled, I could easily load the .geojson file.
There are even more ways to stop CORS for your development environment at this address: https://medium.com/@dtkatz/3-ways-to-fix-the-cors-error-and-how-access-control-allow -origin-works-d97d55946d9
I hope to help someone with this information!
