ahoy！Here There Be Mapnik Beauties

今天是Talk Like a Pirate Day！！一个假期非官方，可以肯定，但有些乐趣向咸狗和陆地机的心灵的心灵相似。这是另一件事乐趣（也很有用）：FME + Mapnik！这Mapnikerasterizer.为您提供基于规则的造型控制来创建与矢量数据的杰作，并将结果渲染到光栅 - 适用于Web和打印。

One of our judges and resident Mapnik expert The Dread Pirate Dmitri gets his arrrrc on at the Esri UC.

我们推出了一场比赛，乘坐七海洋寻找Mapnik主人，为您带来灵感 - 而港口现在已关闭，审判已经发言，目前正在寻找Grog或更多数据。也许两者。

Why announce our Mapnik contest winner today? Because we had (bad pun alert)avastnumber of entries! Arrrrr….

现在，比赛本身不是主题 - 但自9月19日以来^TH.接近......好吧，我们根本无法抗拒机会说出“什么是海盗最喜欢的几何形状？arrrcs！“，办公室周围的滑块，并展示了我们的顶级选择和一个非比赛最喜欢的 - 这都将在即将到来的FME Beta Splash屏幕上出现。

Our Winner! Congratulations to Owen Powell

许多海盗来自英国，我们的价值胜利者也是在西米德兰兹的欧文鲍威尔的贡献，并进入了一个明显的现代美学。

Usingopen data from Ordnance Survey，欧文通过Mosaicking和Hill遮蔽数字地形模型数据在苏格兰准备了这一领域，剥离零高度以产生脆的海岸线。然后，他在该区域举行了矢量数据，并创建了两种交通路线的表示 - 遵循道路网络，可视化流量，以及来自中心目的地的另一个两点最短路由。

当它来造型在Mapnikerasterizer中的数据时，透明度，偏移和弧线平滑是在视觉上平衡两条路线表示的技巧，并创建恒星效果。显示实际道路的红色路线是非常透明的，因此随着流量增加增加了路线的更多副本，红颜色强化以表示更高的卷。使用两点路由的多个副本创建蓝色弧，蓝色和较浅的蓝色，偏移和最大线路平滑。路线目的地是通过在白色缓冲楼的多边形来突出显示的，看起来很像黑暗中的灯光点。

We Can’t Resist a Pirate Theme

Though not a qualified entry in our contest, Mapnik Fever took hold of one Danny Barber, who sent us this rendition of the Caribbean. He took his inspiration from a pirate-themed map print he’d bought in Key West years before, and we liked it so much we’re going to feature it on a splash screen too.

Daniel’s Caribbean map – click for full-size image.

His source data is mostly fromwww.naturalearthdata.com, plus a few images. The vector datasets are global, and he’s used the specify ground extents option in the MapnikRasterizer to clip out the Caribbean area to include. One bit we thought was particularly clever was using a repeating pattern image with a parchment texture (in two different shades) to fill the polygons and create the antique look to the map. Hillshade data, layered over this with some transparency, gives the relief effect.

有趣的宝藏地图样式字体用于标签，单点（用创建器变换器创建）被放置为Compass Rose的锚点，通过在MapnikRasterizer中的图形上进行样式来添加点。另一个漂亮的触摸是地图边框，这是创建边界框的多个副本的结果，具有各种偏移，模式，颜色和不透明度。

由于海盗是一些最早的地图制造商，我们认为这是一个相当适当的应用程序 - 和Aye，她是一个美丽！

Congratulations to Owen on his win! And thanks to Danny, too, for his great work. We hope this gives you some ideas about what you could be doing with the MapnikRasterizer – in your work and as you can see, just for fun too. So look lively, me hearties, and get started with Mapnik here –

And remember, though there be rules in Mapnik, a pirate knows that the code is really more of a set of guidelines…
