9,866,539 buildings in the Netherlands, shaded according to year of construction

Check out all the colours in Rotterdam: <a href="http://dev.citysdk.waag.org/buildings/#51.9159,4.4974,14" rel="nofollow">http:&#x2F;&#x2F;dev.citysdk.waag.org&#x2F;buildings&#x2F;#51.9159,4.4974,14</a><p>Kind of gives you an idea of how large parts of it were destroyed during the second World War and then has had multiple levels of reconstruction and changes taking place throughout the decades since.

It suffers from a Y2K bug: My house in Amsterdam (and a lot of others) are noted as constructed in: 1005 instead of 1905

Starting position is Maastricht? You sneaky bastard ;-)<p>(For non-Dutch people: Maastricht is one of the oldest continuously urban centers in the Netherlands, which makes it nice to show off this kind of technology but it&#x27;s also very far away from the rest of the country. Nice city though, definitely worth a visit).

Nederlanders: When was the BAG established, and how was the dataset created? That must have been an incredible collection&#x2F;standardization&#x2F;digitization project.

Many Americans claim that American cities are difficult to walk or bicycle in because they are all so much newer than European cities. But maps like these demonstrate that a huge proportion of European cities were built in the automobile era, including a great deal post-WWII; the difference in walkabality, mass transit, and bikeability of European cities is not the age of the city center but simply the decisions of what modes of transportation to prioritize in new developments.

I just have to say &quot;Dank u&quot; for choosing a colour scheme that is friendly to those with Colour Vision Deficiency of the red&#x2F;green variety. A huge number of maps which use gradations of colour to represent data are useless to up to 1 in 10 men because they adopt the rainbow colour scheme with red and green representing opposite ends of the spectrum.

Awesome! You can read something from every zoom level. I couldn&#x27;t find my house though, it seemed to be swallowed by my neighbours, but that may be the result of the max zoomlevel. Any reason that one can not zoom in further?

This is really cool, but why don&#x27;t the color gradations go back further? Is it a matter of how records were kept? I would have loved to see how many buildings survive from each century from, say, 700AD on. Pre-1850 as a category seems like such a waste for a map of the old world.

Wow. Even the garage of my parent&#x27;s house is on it, which isn&#x27;t finished yet!

Wow, Brielle is <i>bananas</i>.<p><a href="http://dev.citysdk.waag.org/buildings/#51.899,4.1585,15" rel="nofollow">http:&#x2F;&#x2F;dev.citysdk.waag.org&#x2F;buildings&#x2F;#51.899,4.1585,15</a><p><a href="https://maps.google.com/maps?q=brielle+netherlands&amp;hl=en&amp;ll=51.899032,4.162788&amp;spn=0.02619,0.066047&amp;sll=37.0625,-95.677068&amp;sspn=67.208178,135.263672&amp;hnear=Brielle,+Zuid-Holland,+The+Netherlands&amp;t=h&amp;z=15" rel="nofollow">https:&#x2F;&#x2F;maps.google.com&#x2F;maps?q=brielle+netherlands&amp;hl=en&amp;ll=...</a>

This is initially stunning yet rich, data-dense, detailed and simple. I would refer to this when travelling in the Netherlands and especially for looking at apartments and real estate.

This is incredibly cool; looks like my house and office were built in 1978 and 1850 respectively!

Awesome. Here&#x27;s a building that was built in 1300 <a href="https://www.google.com/maps/preview?authuser=0#!q=Keizer+Karelplein+6+6211TC+Maastricht&amp;data=!1m8!1m3!1d3!2d5.686389!3d50.849285!2m2!1f130.49!2f86.68!4f75!2m5!1e1!2m3!1s0qyuSiw-Tqe-i4x8LdnziQ!2e0!7e5!4m10!1m9!4m8!1m3!1d2148!2d5.691413!3d50.848159!3m2!1i1366!2i655!4f13.1&amp;fid=5" rel="nofollow">https:&#x2F;&#x2F;www.google.com&#x2F;maps&#x2F;preview?authuser=0#!q=Keizer+Kar...</a>

Our house was built in 1976. It took a while to find it though, could use some overlay options or a search bar. Really interesting and cool though! :)

You can see the oldest inner cities and each &#x27;ring&#x27; of newer buildings around it. Example: Amsterdam: <a href="http://dev.citysdk.waag.org/buildings/?utm_source=buffer&amp;utm_campaign=Buffer&amp;utm_content=buffer47b76&amp;utm_medium=twitter#52.3582,4.9145,12" rel="nofollow">http:&#x2F;&#x2F;dev.citysdk.waag.org&#x2F;buildings&#x2F;?utm_source=buffer&amp;utm...</a> Very cool.

9M reads like a brand, I think the title should read &quot;9 M&quot;.

If anyone is interested, I did this for Portland, Oregon back in June.<p><a href="http://labratrevenge.com/pdx" rel="nofollow">http:&#x2F;&#x2F;labratrevenge.com&#x2F;pdx</a><p><a href="http://dealloc.me/2013/06/30/the-making-of-pdx.html" rel="nofollow">http:&#x2F;&#x2F;dealloc.me&#x2F;2013&#x2F;06&#x2F;30&#x2F;the-making-of-pdx.html</a>

Really cool, but every single move I made on my ipad added a new history. And trying to go back after spending 10 minutes playing around was the most annoying thing I&#x27;ve ever experienced. So annoying I had to close my browser and reopen HN.

Pretty much all my suburb of Groningen was built in the late 70s and early 80s. It is cool that many people live in cooler districts, but the Netherlands has a long history of &lt;i&gt;nieuwbouw&lt;&#x2F;i&gt;.

This is really cool. I&#x27;d love to see something like this done for other parts of the world as well. I just wish it wouldn&#x27;t push to history every time you drag around.

My favorite part is here: <a href="http://dev.citysdk.waag.org/buildings/#51.9004,4.5486,16" rel="nofollow">http:&#x2F;&#x2F;dev.citysdk.waag.org&#x2F;buildings&#x2F;#51.9004,4.5486,16</a><p>There&#x27;s a building older than my country sitting right next to one built while I was in college. The casual blend of old and new is one of the things I love about European culture<i>.<p></i>I&#x27;m sure it&#x27;s found in many other places on our humble planet, but I&#x27;ve only been to Europe (so far!).

I love finding things on HN that my mom can also appreciate. :)

Wow.<p>&gt;Building<p>&gt;Constructed: 1300<p>&gt;Address: Keizer Karelplein 6 6211TC Maastricht<p>&gt;Area: 3,306 m²<p>&gt;Function: Public<p>Here is the street view:<p><a href="http://goo.gl/maps/On8Dw" rel="nofollow">http:&#x2F;&#x2F;goo.gl&#x2F;maps&#x2F;On8Dw</a>

Google Maps Mania posted about a few similar maps last week.<p>As well as the Netherlands map there is the Portland map, a map of Ljubljana, Slovenia (similar to the Portland map) and the Brooklyn map.<p><a href="http://www.mapsmaniac.com/2013/08/view-age-of-10-million-global-buildings.html" rel="nofollow">http:&#x2F;&#x2F;www.mapsmaniac.com&#x2F;2013&#x2F;08&#x2F;view-age-of-10-million-glo...</a>

What a terrible use of the browser history. I was trying to get back to HN and had to trace through every movement I took on the map.

The website is really messing up my back button. For example I can&#x27;t press the back button and return to this page.

An excellent example of the techno-fetishism and efficiency&#x2F;dataset worship surrounding a modern nanny state. To quote some prominent graffiti I walked past this morning in central Rotterdam, one mere hour ago: &quot;Is this freedom?&quot; Clearly, no. Holland&#x27;s pretty totalitarian these days.

You could easily make a similar looking map with the NYC Pluto data. <a href="http://www.nyc.gov/html/dcp/html/bytes/applbyte.shtml" rel="nofollow">http:&#x2F;&#x2F;www.nyc.gov&#x2F;html&#x2F;dcp&#x2F;html&#x2F;bytes&#x2F;applbyte.shtml</a>

I would really like to see this for a city like NYC or SF.

sugoi!

It&#x27;s beautiful.
