For 'adventurers' being able to say, login to topomaps nz and being able to place markers at points of interest that you can always come back and refer to at a later date would be amazing. I myself am a photographer and the option to place markers at a potential spot would be an immense addition for many people who use this service.

Cheers

Add an API parameter e.g. mapname="Mount-Ruapehu/Manawatu-Wanganui"
to allow a place name, rather than reference to be used in embedded maps

Often during "Peninsula Tramping Club" trips to this area we visit the HARPER PINNACLES. This is a popular formation up the Harper River (true Right) from the Avoca River confluence.

Such a great resource should be available for iphones too! I would use this a lot, especially with the offline availability. And yes I'm well aware of map toaster, but the overlays with aerial and satellite imagery is game changer.

Currently Street names cannot be searched for. For example Scotts Road and Mangatarere Valley Road are used to access the Tararuas. But you can't find them to plan your drive to the road end.
I suggestion that street names be added to the search, but optionally, so you might have to click a box to include street names into the search.

I was just thinking for this online researching map to make things more interesting in a local and sub-national aspect. And that is to add boundary lines for every territorial unit level within the nation of New Zealand: from regional councils to territorial authorities to wards to even area unit-level divisions (either suburbs & towns & neighborhoods on urban areas or communities & localities & settlements & villages on rural areas). Any thoughts?

For some reason the map is rotated -2 degrees from vertical

Could you please add marine charts to your topo maps options
This would make it a lot easier for me to plan shore diving and fishing trips and will add to your user base.

An app where we can nominate a height above sea level and create for instance a map of NZ from say 250 meters or 500 metres.

Just as we make the Topo50 / 1:50,000 downloads available, make Topo250 / 1:250,000 map sheets and Garmin Custom Map / KMZ downloads available.

The ability to upload GPX, KML & KMZ overlay files directly to the service for displaying over the topo map without needing to self-host using a 3rd party service like Dropbox.

This will make sharing tracks and other overlay information on the topo maps easier.

Adding the magnetic compass cross could be very useful either there by default or as an option

Add DOC hunting areas to the map so they can be searched for and shown on the map.

Make a WordPress plugin available to allow embedded topo maps to easily be added to WordPress pages.

Remember the last location and zoom I was viewing on the map for next time I visit the service.
