    First, great work here – thanks for the high quality maps.

    I’ve developed a light weight GIS viewer / editor I thought some might find useful for working with NaturalEarth data located at:

    https://www.geo-trackit.com/p4Vis.html.

    One function for simple geometry editing is described here:

    https://www.geo-trackit.com/P4VIS_HELP/index.html?editing.htm

    The editing process allows you to select an imported object, retrieve a map server or ‘imagepack’ based image (the image is geocoded then morphed into the app’s native projection) where you adjust the coordinates as needed with the image as a guide. The data can then be exported as a shape file.

    I’ve found this a quick and easy way to do small fix-ups.

    Again, thanks for all your work.

    @MJS: Powerful tool, thanks for sharing!

    Please note that, while there are a few malaligned features like Gibraltar that need fixing, the reason Natural Earth features don’t perfectly follow a feature’s every twist and turn is deliberate to keep the dataset small. The US State Dept maintains another dataset at 1:250,000 scale that might suit your local mapping needs better: 1 of 12 here: http://geocommons.com/overlays/80233

    >>The US State Dept maintains another dataset…

    Excellent resource, thanks.

    If anyone needs digital road maps I’ve added TIGER/Line® ‘All Lines’ support described here:

    The post-processing applies symbology and adds angled-center-centerline street lables.

    Hello,

    For anyone with an interest in OpenStreetMaps I’ve developed an application (with basemaps from NaturalEarthData) to view and export OSM XML located here: http://geo-trackit.com/OSM_Explorer.html. It’s a little rough around the edges but have managed to import single 40GB+ OSM xml files for off-line rendering and analysis.

    Regards,

    MJS
