huge LiDAR holdings of Denmark are now "open data" for free download (instruction inside) Martin Isenburg 2/1/13 2:29 AM
Hello,

I just received word that huge LiDAR holdings for all of Denmark are now OPEN DATA. This may not be the most recent data set but an earlier version with lower point density ... but I just looked at a tiny subset at the corner (the "punktsky_6400_580" download) and that has only 0.5 pts / square meter. Below are the detailed download instructions courtesy of Klaus B. Vestergaard. Unfortunately they do not yet use LASzip (which gets 10:1 compression on this data) and therefore you will probably kill their data servers if you all decide to download all the Danish' LiDAR today ... (-;

Regards,

Martin @lastools

To: Martin Isenburg


Hi Martin!

 

Go to http://download.kortforsyningen.dk/

 

Select (DHM) from the list below Korttype and after you’ve create a new user account you’d be able to login …

 

 

To create an account you need to fill in this form and press “OPRET NY BRUGER”

 

 

 

You’ll receive an email where you can click on the first hyperlink to complete your registration

 

 

This login option appears on your screen – press Log Ind

 

 

Create a solid password, and if you like (not mandatory) your name and phonenumber – press Gem (That’s SAVE in English)

 

 

Go back to this first page and fill in Brugernavn and Password and press Log Ind

 

 

… and click at the DHM/Punktsky link ….

 

 

This pages opens where you can interactively select the AOI by clicking in the map, note that the files requested appears in a list just below the map …

 

 

I recommend that you start by selecting 1 AOI and then click Læg I Kurv

 

 

Now the – Indkøbskurv (Basket) contains 1 item and you can now press Se Kurv (Have a look in the basket) or Bestil (order)

 

Here I’ve pressed Se Kurv and can see the item I’ve chosen, now I press Bestil to complete the order …

 

 

Press Forsæt (Continue)

 

The order is processed and depending on the amout/size of your order and other orders being processed at the same time it can take a while before the page refreshes and you see this ….

 

If you tired of waiting an email is sent to you when the order is ready for download.

 

This is how the actual download look like, note the Tid tilbage is not the estimated time it’ll take to download the order, but time remaining before the order is cancelled.

Now press DOWNLOAD … and you are finished ;o)

 

Well, not the most user friendly download service I admit, but “with a little help from a friend” you’ll get through it ;o)

 

Cheers,

 

Klaus B. Vestergaard

Hello to our Danish friends,

can you tell us what is happening here? I have the feeling that the following tweet by @GST_DHM that came through a few minutes ago announces a new interactive download portal for LASzip compressed LiDAR points of the national holdings:

Nu kan punktskyen hentes lidt nemmere - i "shopping mode" her: http://download.kortforsyningen.dk/content/dhmpunktsky

But I cannot find English instructions. Can someone confirm the good news?

Regards,

Martin @rapidlasso

Martin & everyone...

The "good news" are actually true:
Recent LiDAR data sets are available for download in LAZ format
- primarily in prepackaged 10 km x 10 km blocks.

At this time approximately one third of Denmark is covered.
The rest will be covered during the 2015 flight seasons.

As far as I know, there is no English language version of the
download service, and you need to register as user to access
the data (this is in order to keep proper user segment statistics:
The data are free to download and free to use).

The download selection process is mostly a matter of hitting the "Næste" (= "next")
button twice, then clicking the 10 km tile you request, and log in using
your user credentials (register at http://download.kortforsyningen.dk/ - click
the "Opret ny bruger" (= "register new user") link.

A few Danish terms you may find useful while using the download service:

"Vælg område på kort": "Select region of interest on map"
"Næste": Next
"Brugernavn": "User name"
"Kurv": "Basket/Cart"
"Gennemfør bestilling": "(finalize and) checkout"

Also note that many of the elements on the download pages have english
language pop-ups when hovering over them with the mouse cursor.

regards
Thomas

This is good news, I used the original portal which was quite
user-unfriendly, even if I as norwegian has absolutely no problems
reading danish instructions.

Now I just need to work to make sure that the same thing happens here in
Norway: Even if I personally get free access to any area I want to
construct maps for, it is a big hazzle to have to special order each
area and depend on the county-level mapping service people who can copy
out the blocks and send them to me.

Hi everyone

The HTML-based download portal is great for downloading small areas, but quite useless if you want the entire dataset.

Luckily the same data are available via FTP.

You need to register like Thomas has described. (Go to http://download.kortforsyningen.dk//content/opret-mig-som-bruger It is in Danish, bit translates pretty well with Google Translate)

The login and password can now be used for the FTP server at
 

This FTP contains a lot of open Danish geodata. The new point cloud (da: punktsky) is located at


Happy processing :-)

Best regards
Asger

Hey all!  

This is pretty amazing data! I loaded up 401 Las files, and it is one impressive large data set.  You can view the whole thing here in your chrome web browser with no downloads....it's classified well also!  No doubt they used the amazing http://rapidlasso.com tools.....
