A map (preferably shapefile), free of charge, of the administrative boundaries of the Netherlands which includes the reclaimed land of the Tweede Maasvlakte is what I'm looking for. www.gadm.org offers the kind of maps that I need. However, these maps do not include the Tweede Maasvlakte. Any help to point me in the right direction is welcome.
I would look at the website of the provincial government (Zuid-Holland); the Overijssel equivalent used to provide shapefiles. And if not on their website, I found the GIS staff willing to share all shapefiles prepared by the Province, that is all shapefiles without copyright (e.g. soils could not be shared). You would still have to merge the Maasvlakte boundaries with other files, but that should not be a problem.
If the boundaries cannot be obtained, the next best would be to extract the seaward boundaries from recent imagery and reproject. Be aware that ArcGIS contains (at least the last time I had a look) an incorrect projection file for NL.
Your feed back would be appreciated.
I have not checked if the updated boundaries available on this site but you could try https://www.pdok.nl/ . Otherwise I would agree with Hein van Gils
Thanks for the useful tips!
@Sharon: pdok provides many useful maps. The administrative boundaries provided there, do not really contain coastlines. Perhaps I should have stated that in my question, as my main focus is on the coastline. Also, the file doesn't seem to contain a coordinate reference (although my guess it's in Rijksdriehoek projection).
@Hein: thanks for pointing me to the website of the Province. There are several maps there, but could not directly find what I was looking for. Maybe I will ask around further at the Province.
This is what I used as a preliminary solution. I've extracted the polygon tagged "Maasvlakte 2" from www.openstreetmap.org. and merged it with the boundaries provided by www.gadm.org. As the shapes do not fit seamlessly, I had to do some manual tweaking. Not ideal, but it gave me something workable to produce simple maps with a coastline.
For those interested, I've attached the Maasvlakte 2 shape as an R-object, plus the R-code I've used to merge this shape with the boundaries provided by gadm.org...
If the boundaries are not available from official sources, the same can be generated from multitemporal image interpretation.

For completeness sake I've also extracted water bodies from openstreetmap.org at the Maasvlakte and saved it as RData file, which can be included in the R-script I've posted earlier.
On land and sea geological services/survey departments and mining licenses overviews are often a rich source of shapefiles for various territories for obvious reasons. For example, here in Namibia the only sites with boundary shapefiles of national parks are from the mining sector.
Please be aware that the Rijksdriehoek projection embedded in ArcGIS used to be incorrect, as I found out the hard way during hands-on GIS teaching in South Africa. ESRI was informed over the years to no avail. Maybe the error has been corrected?
Hi Pepijn,
I am also looking for a nice shapefile of the Netherlands with the Tweede Maasvlakte and the Sandmotor...
Can you maybe help me.
Vriendelijke groet,
Maarten
Hi Maarten,
At the moment, I don't have any material other then posted earlier in this thread. I wasn't successful in finding vectorised maps of the Sandmotor. I'm sure you can come up with something creative...
groeten terug,
Pepijn
