ENC
The ENC viewer provided by NOAA is just a demo tool & not intended to be a serious navigation package. The products are in a digital vector format (structured/stored as a database), which is where this is all headed. The old physical (drawn on multiple sheets) map/chart masters used to lithograph the paper maps/charts were initially (first phase) digitally scanned (raster charts), but that format will phase out; vector maps/charts are the second phase. Most initial vector offerings were digitized from the older paper chart masters, but gradually new satellite imagery will be digitized to update & replace them.What we're seeing is the result of a long-term Gov't strategy to get out of the map/chart publishing business and focus on its inherently Gov't function of mastering & maintaining the underlying digitized database. Private industry is better suited to developing, marketing, and supporting the end-user products and services.One thing that ENS will do is establish a de-facto Open Standard for digital map/chart products. That done, anyone with the smarts & capital can develop end-user products & services to utilize the publicly available data. Open market free competition is generally a good thing for consumers.This has created somewhat of a dichotomy in the industry regarding what their business focus is/will be (e.g., what is their product? who are their customers?).Take MapTech, for instance. Their traditional product line has been to re-package the Gov't map/chart data into digital and paper products for consumer use. If you purchase their Digital ChartKit, for instance, you get free their Chart Navigator software (also a free downloadable from their website). They sell separately their enhanced version of the software (Off-shore Navigator) to use on-board. So, are they a software house or a map/chart house, or both? If ENS takes off as an open standard, will that drive a change to their business strategy? My guess is they (and just about all the other companies) will shift to being predominantly a software & services provider and allow people using their product to download directly from NOAA any/all the ENS maps/charts they want.Could a bunch of techie/boaters develop their own open freeware to do the navigation & planning functions -- sure! But you'll be fighting a competitive commercial marketplace that can sell those products at fairly low prices.The key for us consumers is to encourage & support the idea & substance of Open Standards for map/chart data, and the Gov't business strategy of putting the maps/charts on-line for free download by anyone. And as citizens to insist that our Gov't devote the priorities and resources to maintaining the accuracy of those data.--Ron
