Hi Yaqiang,

I did not expect a new release of your lib so fast!
And also thank you very much for the online documentation.

I can't tell you how your library is useful for me!
I will spend some time here to explain you how I use your lib. I think it is interesting for you to know how users use your work.

It is funny because I work on two totally different projects, and your libs were useful for both of them.

1) my web site www.yadusurf.com
This web site shows graphically the surf (wave & wind) forecast for the next 7 days. It is designed so that the users (surfers, mainly) can get their information in less that 10 seconds.
On my server I user different kind of data sources : NOAA (GFS for wind, WaveWatchIII for the waves) and Previmer which is a French public oceanographic service.
Recently Previmer changed its data format for latest data products. My existing tools (GDAL) were not compatible with these data.
I struggled to find a C# compatible library to read these .nc files. Finally I found MeteoInfo, and it works!

2) the "Reef explorer" project.
I am creating a marine robot that is intended to make measurements of the bottom of the sea, in order to create marine charts on small and shallow water areas.
Right now I do this just for fun!
This robot is a 1m length catamaran, and follows automatically a kml route, using a compass, a GPS and a microcontroller.
I am working on it since 2 years, and I start to get good results (in lakes for the moment).
It has a sounder that measure depth of the bottom. With depth + GPS 2D position, it can collect on a SD card a set of 3D points.
I was looking for a C# tool to create a surface from this point cloud.
This evening I worked on integrating your Cressman function, and here is the result. It is working very well!
You can see the route (blue polyline), the track of the boat (gray polyline), and the Cressman surface (shaded in grey).


Looks good isn’t it?

Best regards,
Mathieu

那哥们搞了一个水下机器人，通过在水底设定的路线行进来测量不同位置的水深，然后通过wContour的插值和等值线算法绘制出水底地形。

从名字和他的网站上看像是法国人。你的英语比我强，我连四级都没过。

在有道的帮助下居然看懂了，莫非这段时间英语学习还是有效果的！希望下周考试顺利通过！

佩服佩服~

感觉人家的动手能力还是比较强的，微控(microcontrollo)，机器人，想是已经突破软件，谋求和硬件相结合了。再说国外不少机器人大赛也当真很厉害的说······
