I'd find it useful to allow parameters on Permalinks
e.g. https://www.topomap.co.nz/NZTopoMap/nz43535/TARARUA-RANGE/Wellington&z=12
currently this URL produces an error message

Merge the LINZ nz632 sea chart (https://www.linz.govt.nz/sea/charts/paper-charts/nz632) with your 1:50 topo map of Banks Peninsula?
We want the depth and water detail of the sea chart but the land detail of the topo.

Similar to the UK's Ordnance Survey service - https://shop.ordnancesurvey.co.uk/custom-made/

Larger wall sized map orders would also be a great option.

Update the status ( open (-----), closed (--X--X--X), damaged (--xxxx--) )
of all DOC tracks. Use DOC notices or just scrape from DOC maps.

e.g. https://www.doc.govt.nz/map/index.html?banner=0&layerlist=0&base=Topo&layers=Campsites,Huts,All%20tracks&extent=1845446.99491999,5843151.833545,2193,7&search=Huts:100039054

As far as I can see all previous uses of "Rimutaka" on the topomap have, appropriately, been changed to "Remutaka", following the Geographic Board's decision of October 2017.

To complete this change you need to update the searchable list of feature names, which still has multiple occurrences of "Rimutaka" and none of "Remutaka"

When plotting from a GPX file show a different colour for each track segment (as defined in the GPX file).
When plotting from a GPS file show waypoint and name.

Improve the search so when I enter say "murphy" it finds "murphys" etc
e.g. murphy is the equivalent of murphys* (string plust wildcard).

Alternatively allow users to specify wildcards

Its not clear how or why the search results returned are ordered.
I'd like to suggest some options be provided.
1) closeness to location shown on map currently displayed
2) strict alphabetically
3) north to south or vice versa)
and possibly a filter, e.g. restrict to region.

Allow Open STreet map as a layer for non NZ locations

1)login option by facebook etc
2) add marking points so I can drop a pin where I climbed or visited
3) add 3D map
4) add racing route options so I know which route I walked

Add to the API the ability to specify the layer and the transparency.
e.g.
&layer=aerial
&tp=50 (percent).

include a 'pen' button that, once pressed, allows you to draw a route on a map in a separate 'layer' which could then be saved or shared with others. Also distance could be calculated - either based on topography (if possible) or as the crow flies.

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.
