roelant - OpenStreetMap Mapper

##Whoami?

Hi, I'm a mapper from the Netherlands. I recently became more active, after some initial casual steps such as adding a local POI, or adding oneway to a roundabout when on holiday and annoyed that the local offline router would send me against traffic.

Recently I've joined the community in an effort to make the openstreetmap the most accurate and up to date map available - at least where I can help it. 😉

To do this, I look stuff up on the wiki and will contribute there on occasion as well when I think I've got something to add. I try to keep my osmose issues at zero at all time and learn about quality mapping while doing so (but had to give up on OSMI unfortunately).

If you came because you came across one of my changeset and have questions, you might find the information below helpful. If you would still like to know more, please don't hesitate to send me a private message.

Sources

As many Dutch mappers, you'll see me rely heavily on Dutch open information sources, some of which are made available as layers in JOSM even. I'll credit them in my changeset by acronym (as do many), below you find a list of what they are.

BAG: Basisregistratie Adressen en Gebouwen Aka the Key register Addresses and Buildings This contains information about (and mutations on) Dutch buildings and can be imported / updated from with a special JOSM plug-in.
BGT: Basisregistratie Grootschalige Topografie Aka the Key register Large-scale Topography Contains information on local elements varying from roads and all their (traffic calming), streetnames, to tree's/landuses, public amenity's, etc. Available as layer in JOSM.
DKK: De Kadastrale Kaart (of ook wel BasisRegister Kadaster / BRK) Aka the Key register Kadaster Contains the cadastral registration and the cadastral map (Kadastrale Kaart) - where land ownership and buildings starts and ends.
KvK: Kamer van Koophandel Aka Chamber of Commerce Information about companies and where they are registered. Mainly access this trough their website to see if the company still exists and/or if they've moved.
Oblique or S&P Oblique: Slagboom en Peeters Geo-obliek beelden Aka Slagboom en Peeters Geo-oblique images Oblique aerial imagery are high resolution pictures taken from an plain. I've obtained access/license to use these for OSM from Slagboom en Peeters and mainly use them to verify what's there in more detail, or figure things out can't be seen from regular aerial (satellite) imagery. I'll add source=oblique especially to objects that I couldn't have otherwise added, and will credit Slagboom en Peeters in the source changeset as well (and when using source=aerial, I'm referencing regular aerial images).
PDOK: Publieke Dienstverlening Op de Kaart Aka Public Services On the Map PDOK is where open source governmental information of The Netherlands get published, as usable layers for on a map among other things. Besides having high quality recent satellite imagery available, they also host some of the aforementioned data-layers, such as BGT. If you want to get blown away, have a go at their Pdok viewer.
Aerial / Aerial Imagery This one is the exception to the rule: this obviously depends per region, and will be specified in the source of the changeset. However, when referring to Aerial, I'll always be referring the latest satellite imagery for that region at that time unless explicitly stated otherwise.

Changelog
