NZ Linz nautical charts to be more accessible

As our public viewer is not yet available (currently under construction, upgrading to Google Maps API v3 as v2 is officially no more supported),
this info is primarily intented to our iPhone/iPad universal mobile application users (Marine NZ on the App Store)
and also to our B2B customers which use our nautical charts layers in their own webmapping applications through our GeoGarage API.

From 22 November 2013, Land Information Minister Maurice Williamson announced mariners can now access free online navigational charts in a new, and more widely accessible, format as the government continues to make more publicly held information available for reuse.

Land Information New Zealand today made its Raster Navigational Charts available in an unencrypted BSB (.kap) format that’s more widely supported by software manufacturers.

“This is great news for recreational boaters, who are much more likely to have on board systems that support the new format.  The change also removes the need for special licensing or permits,” Mr Williamson says.

Charts will also be available to software developers to use in creating apps and other types of value added products.
“LINZ maritime information is already being used to create apps for mariners, and this latest initiative only opens up even more possibilities for developers.
“Making Raster Navigational Charts accessible is another example of the work the government is doing to make non-personal data easier for people to discover, use and share,” Mr Williamson says.

Regarding the GeoGarage, the quality of the display for the Linz charts both on the web or on the Marine NZ iPhone/iPad universal application is right now improved as the resolution of the BSB material (254 dpi) is better than the unencrypted previous format HCRF (127 dpi) used in previous digital charts material.

181 charts (318 including sub-charts) available in the GeoGarage (catalogue).
