I have found this excelent tool
My Maps -> Static Map Converter
Which does what I want, converting polygons, polylines and markers too.
But it has a limitation. It generates URLs so big that the static maps API returns:
The remote server returned an error: (414) Request-URI Too Large.
I know that encoded polylines can be simplified until the URL be short enough to work.
Is there any Web App which converts "My Map" to a simplified version of it using Static Maps?
Is there any other Web App which could at least take an screenshot of Google Maps and generate an image for it?
Best Answer
As far as I am aware there is no way to generate an image from Google Maps.
The only way would be to take a screen shot using your OS or use a screen capture software.
