I believe relying on govmap.gov.il as a source for a street name is definitely allowed. As for the citation, I believe referring to it the way I did is, much more then what is required. Must you cite en.wikipedia.org if you have your own picture of the statue of liberty and you wrote it is called the statue of liberty because that is how en.wikipedia.org names it?
