    Plotting 1500 postcodes on a map

    I have a CSV file containing about 1500 postcodes of students which we'd like to plot on a map to show where they travel from.

    I've Googled and Googled, and with there being a short deadline for this (Thursday) it's not really viable to delve deep into the Google Maps API and write my own solution.

    The closest I've come to in terms of using a web based service is ZeeMaps, but although I could import the CSV file, the final result wasn't as hoped (some markers were placed hundreds of miles from their corresponding postcodes).

    Has anybody done this before? How did you do it? I'm sure I have done in the past, but can't for the life of me think of the website I used to do so.

    Thanks in advance.

    There's a tutorial here about using Google Earth Plus, or Pro to do exactly this.

    Apparently in Google Earth Plus you're limited to 100 items per time for import so you'd have to break it up a little, but I don't see why it wouldn't work otherwise.

    Not free, but Microsoft Mappoint will do this and much, much more

    Thanks jamesb.

    I've not even been limited to 100 items per time, and so now my only task is to import the KMZ file I've exported from Google Earth into Google Maps.

    ...which has proven problematic as Google Maps will only show a maximum of 200 markers at once. There's a workaround which involves uploading a KML file to some web space and then simply entering its URL in the Google Maps search box but, although it works in principle, in reality it just can't handle 1500+ markers.

    After much research this afternoon I've opted for Click2Map, which is a really impressive browser based solution and has done everything I hoped for, including clustering.

    There's a completely unrestricted 30 day trial, and it's likely we'll end up paying for a license.

    Plotting 1500 postcodes on a map

    Hi,

    Came across your posting of how ZeeMaps did not properly plot your postcodes. We have since then improved our geocoding, so you might want to try again and see if ZeeMaps works for you.

    Thanks

    Claire

    Sorry for the necro but has anyone come up with a solution for this?

    I have a list of UK postcodes that I want to turn into KML (about 9600), I can't use online services because it's sensitive data...

    Isn't a postcode alone not actually considered sensitive? Any ideas?

    I'd have said the same, if it's just postcodes and nothing else, it is not sensitive information, anybody can print off a list of post codes from the web, their mere existence is not sensitive data.
