Land Information of New Zealand has made available a great set of 1:50,000 scale Topographic Maps available online. I downloaded all 455 of the maps covering the main island of New Zealand and converted them to a seamless Google Earth overlay.
The maps show roads, placenames, contour lines, elevations points, etc, and make a great tool for planning hiking trips and other outdoor adventures. Since they are Google Earth overlays, you can also adjust the transparency of the topographic maps to compare the maps with the underlying imagery available from Google Earth. You can also see the names of features from Google Earth on the maps.
There are two versions of the topographic map overlay available. The free version is designed to be used online and has highly compressed images to allow for faster loading. The Pro Version is designed to run from your local computer, does not require an internet connection, and has much higher image quality.
The Pro Version is almost 9 gigabytes. Make sure you have enough space on your computer and a high speed internet connection before purchasing.
|Free Version||Pro Version|
|Internet required||No internet required|
|Lossy compression||No image compression|

The original GeoTIFF files can be downloaded (very slowly) from LINZ.
