my client prepared google map with points on. Now he wants that points on map in iPhone app. Is there way to export points from map prepared by him ?
If your client prepared the map in Google Maps, then he can use the "KML" link in his Google Map to download a file with all his data points in it, in KML format.
Did he use javascript to prepare the points and can you get that? If so, use the source.
Did he use maps.google.com to prepare it by dropping points on that? If so, click the URL button and you'll should see the points embedded in the URL, at least that is true for driving directions.

Currently I am using Selenium and Folium to download OpenStreetMap maps... The issue I am encountering now is that, for my next assignment, I have to download 5 million images, and my current Python script is too slow. Having that one running in the background for hours on my laptop is not really an option.
Currently, my script opens the browser, saves the screen and extracts the nxn pixels image I need.
Does anybody know of a smarter way of extracting maps from OpenStreetMap?
Currently, I have a CSV list of 5'ish million x & y coordinates of points, and I need to download a map for each one of these in png-format... How should I proceed?
I hope you are not downloading from openstreetmap.org tile servers, because this is strictly discouraged as you can see on https://operations.osmfoundation.org/policies/tiles/ under "Bulk Downloading".
It might make sense for you to setup an own tileserver or subscribe to some tile-server service. There are static map services, which allow you to download the combined map image of an area, see
https://justmarkup.com/articles/2014-05-27-overview-of-static-map-solutions/#openstreetmap
for example.
This mentions Mapquest and Mapbox.
I am trying to replace the default location points and addresses with my own points and addresses. I have uploaded a geojson with parcel centroid points, address, and assessor parcel number. I would like to display this information when the user clicks on an address. Is this possible?
geojson upload
You can follow this add points to a web map tutorial series to achieve the functionality you are looking for. Since it sounds like you have already uploaded your data to Mapbox as a dataset or tileset, the next steps will be to create a style and then add interactivity by displaying popups containing the desired information when clicked.
I'd like to transition the map in my app from currently Apple-Maps-SDK to Mapbox. My users already downloaded a lot of offline maps into several .mbtiles tiles containing raster data.
My question now is if it's possible to still use those while the user will be transitioning to the new maps? I just don't simply want to delete all offline maps and tell the user that he needs to download everything again right now, but rather give them a time-window to do that...
I was looking at MGLRasterTileSource/MGLSource and thought that I can create a subclass and somehow provide my own data to the map, but this does not seem to be supported. There are no datasource methods on it for that purpose...
Would be great if somebody could point me into the direction on how to archive what I want.
EDIT:
So I thought it might work that way... I migrate my existing raster tiles into a downloaded pack inside the mapbox offline database. So I had a look at the caches.db but at least the data in there is not just a plain png/jpg (tried with the mapbox satellite images, which should be raster).
Cause there is no public interface for getting existing raster-tiles in there, is there?
I've seen an other solution where somebody is hosting a webserver inside the app... but that somehow looks like quite an overkill to me?!?

My matlab is generating a .kml file and it opens in google earth. Is there a way to change it to open in google maps instead.
And also to discount the first values which is an unknown number of 0,0
Thanks.
code
kmlwrite('routetraveled', B.data(1:elements,4), B.data(1:elements,5));
winopen('routetraveled.kml');
I use this to generate the .kml and open it.
I don't know if Google Earth supports it, but many apps allow you specify a file to load when you open the program. Instead of winopen, you would just make a command line call. Something like this:
!Path/To/Google/Maps --open filename.kml
I have download a partial area data file (OSM format) to local. I have a local server which not connect to internet. So I want to build a local map app only with local OSM file (I use OpenLayer js).
I searched openstreetmap.org wiki, but find no solution.
Is there any way or documentaton to solve this?
By "local" you mean local on your machine or a local web server?
First you need to generate map tiles. Then you prepare the map HTML, including the OpenLayers code. The tile URL should point to your tiles (in case of a local machine, just use the "file://" protocol for URLs).
Here's one way how you can generate tiles (you can skip some of the steps): http://braincrunch.tumblr.com/post/9921938947/maperitive-tutorial-a-hiking-web-map-in-ten-easy-steps
1) i have to create an API that connects to a locally downloaded openstreet map and does to following:
2) Given a GPS location display the location on the map.
3) Be able to display the route to the location and update while the individual is on the move.
Numbers 2) and 3) are not yet my problem. number 1) is my problem for now. i don't even know where to start. i have been searching but still saw nothing i can understand.
what i want to know is: where to download OSM that i would be able to use locally? an example or a tutorial on an API that connects to the map locally and able to display it(and maybe able to zoom in, zoom out)?
the API can be in java, c#, or c++. but any other language is welcome as i have no choice.
