All,
I wanted to create a set of POI's representing active and closed mines (we like to rockhound). I tried a number of utilities around to convert the data which can be had in a number of formats. I didn't have good luck with any of the tools (like GPS visulizer, etc).
I decided to write an application to do the conversion myself. It takes the data from the US Geologic Survey Mineral Resources Data System output in a csv format and converts the data to a 4 field csv format compatible with Garmins POILoader. The fourth field can be a combination of the mines information like minerals, ore, host rock etc.
