static-maps | Turn markup into google maps | Web Services library

I was migrating my maps to use the premium plan and followed the instructions:

https://developers.google.com/maps/documentation/static-maps/get-api-key (these are for the static maps, but I believed same applies for other apis)

Paragraph - Generating a digital signature to use with client IDs

I was able to generated a digital signature for my script result in something like:

It works but I receive a warning saying that the signature is not requied and indeed it works without a signature.

Apparently I need a signature for staticmaps and directions, so why does this not apply for standard apis?

I was trying to find a full list of apis for which I need a signature and for which I don't, but to avail. Can someone give a clue, please?

I'm working with the Trello API. I want to attach an image to a newly created card. I have no problem POSTing the new card and getting the card id to then PUT the attachment.

My project is made in Laravel 5.4 and I'm using Guzzle to make the HTTP requests.

The image I want to attach is from the Google static maps API and I'm using an encoded polyline (which I generate using this script) to draw a figure over some area.

This is how the card should look like:

But it ends up looking like this:

If I go to Trello and attach the image (as an URL) manually everything works perfectly but when I do it through a HTTP request it looks like the second image above.

After doing some research I think the problem resides in the polyline string because it usually contains some characters that HTTP does not support. I've tried using PHP's urlencode() without any result.

I send the image URL as an URL encoded param since that is the only way the Trello API accepts it (even though the official Trello API docs say otherwise).

Do you guys have any other ideas | work-arounds | experience with this issue?

Is it possible to have dashed line in the map paths? Can't see any option about it in the official Google static map page.

I would like to use Google Maps tiles for maps inside of my Wolfram Language projects. There are currently 18 Google Maps APIs and I think I need the Static Maps API. However, this API appears to return whole maps instead of individual tiles.

Which API do I need for use as a URL tile server for the GeoServer option in the Wolfram Language Maps & Cartography functions? Also, where is there official documentation of the URL tile server in Google's documentation?

From @ChrisDegnen answer below I think the Static Map API is the only option. However. I wanted to use the map as a background to the existing Maps & Cartography functions in the Wolfram Language. Unfortunately, the Static Map API does not allow explicit specification of the lat-long boundaries so it is not a good fit.

For example to map the continental USA using the "visible" parameter to set the map bounds.

So, i have custom route on my map. I put in on my web (local page to be precise). Unfortuently, on high dpi screen texts are very tiny. I've found static maps to be able to rescale map (https://developers.google.com/maps/documentation/static-maps/intro) but have no idea how to show my custom route on static map (route was generated from GPX file).

Is there any way to do it?

Regards!

I want to generate a static maps image using google's static-maps API. My requirement is to display as many markers as many stops are there.

For example if my route has three stops First S1 than S2 and last S3; than three markers should be shown and path should be draw among them.

I am adding three markers as shown below :

I am trying to use an SVG (several paths) as a marker for a Google static map. This answer seemed to suggest that an SVG path is possible but I cannot see any example in the documentation.

Is it possible to use an SVG (either via a URL or with the SVG path), or shall I just stick to a transparent PNG?

When I put my url and signature into the space provided to generate a sample signed url my signature comes out different than Google's. I've checked and rechecked so I don't think there's any dumb mistakes. So maybe I misunderstood something or I translated something from the Python code wrong?

my code:

I'm brand new to MapBox, but like the images it produces, and want to be able to use their API to render some GPS points nicely.

Given a Standard GPS point (and a MapBox zoom level), how can I find the Lon/Lat values for a suitable MapBox 'tile' ?

The actual code that I'm trying to use is the Python code at:

https://github.com/mapbox/mapbox-sdk-py/blob/master/docs/static.md#static-maps

And my starting GPS point is in Auckland New Zealand -36.8,174.7.

https://www.google.co.nz/maps/place/36°48'00.0"S+174°42'00.0"E/

I have naively tried entering "standard" GPS coordinates:

from mapbox import Static service = Static() response = service.image('mapbox.satellite', lon=-36.8, lat=174.7, z=10)

but this results in the error message:

mapbox.errors.InvalidCoordError: Latitude must be between -85.0511 and 85.0511

Searching for this error message led me to this:

https://en.wikipedia.org/wiki/Tiled_web_map

But I still have no idea how to determine the long/lat values of a suitable tile. Any help would be appreciated.

Thanks in Advance
