I'm cresting electron app using node-canvas.
I generated an app-installer by the following command:

$ electron-builder --mac --x64 --config ./build_mac.js

build_mac.js

Why I can't get the correct date from the array?

I tried to get the correct date from the array, I use Log.d methods, the date has in the array, but when I click the listener, I always get the last date. where is the problem?

Below is my code:

I'm implementing github.com/jawj/OverlappingMarkerSpiderfier to make clusters of Pin's on my google map.

What I want to do is to have a i cluster icon with a number in it that tells the user how many pin's there are - Just like google default cluster view. Se screendump. If it's not possible to have a number, that is okay as long as i can set a cluster icon of my choice. Screen shows how clusters looks on google https://developers.google.com/maps/documentation/javascript/marker-clustering

When i click the cluster it opens up and show the pin's. In my case each pin is a small thumbnail. Se screendump Screen shows how it looks after i click the cluster

My problem is that i dont know how to make something like the google cluster solution. My code show a thumbnail as the cluster icon (see screendumb) and i want the 'google solution'. Screen shows how it looks before i click the cluster

I am trying to insert a small set of rows into sqlite using python and getting an error "Cannot operate on a closed database"

This is my code snippet:

I am trying to render directions polyline on map using coordinates from MapQuest REST API but I get the polyline not showing on top of road exatctly. Rather its showing a different output. I want to draw the polyline on top of the road exactly. I am sending the following request to get the directions (using MapQuest Directions Route API):

http://www.mapquestapi.com/directions/v2/optimizedroute?key=[API_KEY]&json={%22locations%22:[%2234.0120337,-6.7383617%22,%2234.0253894,-6.7592364%22]}

Then depending on the above request session id, I am sending another request to get the coordinates (using MapQuest Directions Route Shape API):

http://www.mapquestapi.com/directions/v2/routeshape?key=[API_KEY]&sessionId=[ABOVE_REQUEST_SESSION_ID]&mapWidth=320&mapHeight=240&mapScale=1733371&mapLat=34.0120337&mapLon=-6.7383617

I am using the array route.shape.shapePoints, How I am I supposed to get polyline correctly plotted above roads on map?

Code I am using:

I am working with OpenLayers. adding vector layer on checkbox click with lat lng. but I am trying to remove that layer with same lat and lng. but not working.

Any help will be appreciated.

I'm trying to get started doing geocoding with OpenLayers and Nominatim, but when I try to change the view of the map (say, because the user entered an address and I want to center of the map on it) I get an error:

I'm doing an web application that uses Open Street Maps and I'm adding some markers to it. I need to delete all layers that are on the map.

I´ve already tried some examples that I found on other questions but none of them worked for me. I'm not sure if I'm using open layers.

Here is the code to create the map:

I want to integrate Google Maps into OSM because of Google API charges. So I want to show MarkerWithLabels in an OSM map. How would I achieve it? Function LoadVehicledata() used to display an icon on particular location works fine. But function DisplayMarker() does not display a label on a particular Lat Long. I want combine the above functions to show a label with icon on that Lat Long. I tried so many ways. Any suggestions?
