Making charts for use with OpenCPN

Ever wanted to make your own charts with OpenCPN?

To make it easier, I wrote a simple web app to overlay the chart using the Google Maps API Ground Overlay feature, and then automatically generate the KAP header text. Of course the generated KAP header is only as accurate as the bounding box coordinates, which you should be able to obtain from the original paper map, along with the scale. You can also align the chart with the Google Maps satellite view, but bear in mind that the accuracy of the latter's coordinates varies considerably, ranging from a few meters to tens of meters.

Forum rules preclude linking to my blog post which describes how to use the app, but here is the app, which is free:


It's pretty self explanatory but search for "Arriba chartlayer" to learn more.
