Getting Danish landscape information Tutorial Part 1 There are multiple types of data, helpful to the trackbuilder available from the Danish government. Such as DHM (The Danish Height model) and Orthophotos (airplane photos). DHM consists of LIDAR, that is LAS pointclouds compressed into LAZ files, different kinds of ASC surface models and large GEOTIFF images. I will do another tutorial on getting the Orthophotos to keep this tidy. The Danish data is downloadable from here: http://download.kortforsyningen.dk/ The requirements for for using the data, is to at someplace mention the name of the dataset, the download date and where it comes from. I use this: Copyright notice Padborg Park Point cloud and Ortho photo As required, according to this site: (In Danish) http://download.kortforsyningen.dk/content/vilk%C3%A5r-og-betingelser Contains data from Geodatastyrelsen and Danske kommuner Fot-data Ekstracted lokation : Padborg Park DHM/Point cloud DLD 24/3-2016 punktsky_607_51_LAZ_UTM32-ETRS89.zip DLD 24/3-2016 punktsky_608_51_LAZ_UTM32-ETRS89.zip http://download.kortforsyningen.dk/content/geodataprodukter DLD = Download date DanTDBV D@nN (My photo and film signature) You need to register before you can download anything. In the Log ind box chose Opret ny bruger Enter your information in the relevant boxes You only need to check the top checkbox. Click Opret ny bruger I cannot remember the rest of the registration proces, and I am not to keen on registering again. If in doubt post a screenshot and I will help you on. You do NOT! Need to logged in, to browse around in the data. For LIDAR data Click Gå til DHM link DHM = Danmarks HøjdeModel = Denmarks Height Model The different links sends you to a page, with a description you can copy to translate. Current dataset with trees and buildings is DHM/Punktsky http://download.kortforsyningen.dk/content/dhmpunktsky The looking glass is a search function you can use in all 3 steps. You can search for streetnames and places. You can even find the permanent Danish racing tracks. (Hint! Motorbane is a racingtrack). In step 1 and 2 you can leftclick and drag the map around and zoom with the scrollwheel. I am downloading Padborg Park in this session. 1.Udtræksmetode V 10 km blokke, is saying that each selection, is a 10 km square. In some of the sections, you can select smaller chunks. It is a new function and I have not tried it yet. Use the map to find the area you are interested in. When you can see the desired area Click Næste 2.Format og koordinatsystem Format (Chose file format) Koordinatsystem (Chose coordinate system) If you don't get any choises, click Næste 3.Vælg område på kort Click on the areas that you need You multiselect by clicking the next area. Selected datasets show up in the sidebox. Click again to deselect. If you cannot select anything, then it means there are no data, for that area yet. You can skip step 1 and 2, if you know that selection, format and coordinate system is to your liking and do your search in step 3. When you have chosen what you need: Click Læg i kurv You get a list with the filesets you have selected punktsky_607_51_LAZ_UTM32-ETRS89.zip punktsky_608_51_LAZ_UTM32-ETRS89.zip Click Gennemfør bestillingen Log in (When you have logged in once and have asked you browser to remember you, you just need to click on fortsæt to log in.) Click downloade din ordrer her Rightclick and Save as I chose to add the name of the area, I want to extract from the files and the downloaddate. Padborg Park 24032016 punktsky_607_51_LAZ_UTM32-ETRS89.zip Padborg Park 24032016 punktsky_608_51_LAZ_UTM32-ETRS89.zip Each zip file contains a number of 1km square laz files. To find which files to use we go to: http://miljoegis.mim.dk/cbkort? Enter the name of your area in the search field. In some cases like Nisseringen and Jyllandsringen, that is enough. In others like Padborg park, you will need to find the adress, for the place or one close to it. The adress for Padborg Park is Flyvepladsen 10, 6330 Padborg Click Ortofoto in the left collum Click the buttons on the right side until the map turns into an airphoto Click Værktøjer/Chose Vis Koordinater og lokaliser position Now click on the 4 corners of the area that you are working with in turn and look at the coordinates you get here: Koordinater i ETRS89 /UTM zone 32N For Padborg Park it is roughly 517629.33 6080487.64 517951.73 6080507.64 517343.73 6079933.24 517602.13 6079852.44 Our real interest here is the underlined numbers, it tells us the files to use. PUNKTSKY_1km_6080_517.laz from set punktsky_608_51_LAZ_UTM32-ETRS89.zip PUNKTSKY_1km_6079_517.laz from set punktsky_607_51_LAZ_UTM32-ETRS89.zip In this case it is 2 files. This should be enough to get you going. If you have any questions please ask and I will try my best to answer. Happy track building.
