Map World: China unveils own mapping service
22 October 2010 Last updated at 10:43 GMT

China has launched an official online mapping service called Map World.


The site has high resolution images of many Chinese cities

The web-based service gives people access to increasingly detailed satellite images of China and high-level images of other nations.

The flat maps can be viewed in 3D if visitors download and install a browser plug-in to convert the images.

China said the service was still in development and would be updated regularly. It said it could currently handle about 10 million visits per day.

Map World has been created by China's State Bureau of Surveying and Mapping from satellite images collected over the last four years. It said the information depicted would be updated every six months.

Within the nation's borders, images have a 2.5m resolution in rural areas and can go down to 0.6m resolution in 300 cities. Beyond its borders, images have a 500m resolution and many nations are blank when users zoom in.

Mapping services are tightly restricted in China and any company wanting to offer them must obtain a licence. This imposes strict conditions on what they can show and where the servers hosting the service can be located.

The Mapping bureau said about 80 companies, including Nokia, had bought mapping licences. Google is not thought to be one of them.

When China announced plans for the map licence scheme the search giant said it would consider its options before deciding whether to sign up. Google does have maps of China on its services but they are not as detailed as in many other nations.

One stumbling block could be the widely publicised shift of Google's servers out of mainland China to avoid official oversight of what its users were doing.

Interesting.

Unfortunately some of the features such as 3D requires Internet Explorer. It sucks how much most countries in the world rely on IE, arguably the crappiest browser in existence.

yeah hopefully this has newer imagery than Google Earth, things change so fast in China, they need to update more often!

I like it, for it has far more updated information than google earth. It is still only a test version, so IMO its accuracy weighs much more than the interface.

I like the 3D interface of e都市 better, but the coverage of e都市 is quite limited compared to 天地图. For public transportation, 丁丁 is still the best.

Anyway, more competition is good for users.

The map doesnt look more updated than Google. Google map shows the Shanghai Center plot finished its digging, and the Chinese one only shows them starting to dig.

To be fair, the Chinese Map Worl was launched just recently and google has refined their service fir over ten years. Give them a few more years and let's see how they will have improved their service and then judge them.

天地图被指抄袭谷歌 测绘局称拥有知识产权

  国家测绘局于10月21日推出“拥有自主知识产权”的网络地图网站“天地图”,并称这是中国区域内数据资源最全的地理信息服务网站。不少网友在网站开通的第一天,就对其进行深入的体验,却发现“天地图”的部分卫星图与谷歌地图一模一样,甚至有网友因此怀疑“天地图”抄袭谷歌地图。国家测绘局其后否认“天地图”抄袭谷歌地图的说法,但承认使用的卫星地图来自谷歌地图的合作方美国DigitalGlobe公司。包括Google地图在内的所有商业地图,都会在地图的左下角或右下角注明地图数据来源,而“天地图”却不在地图上注明数据来源。

  “天地图”的官网上有意见栏,截至目前,上面已有一千五百七十余条网友留言,绝大多数的留言显示“天地图”的用户体验十分不理想。有网友称“具有自主知识产权”的软件系统只不过是对几款商业地图应用的拙劣模仿。

  卫星地图用Google用过的旧数据

  10月22日晚,一位网友发表文章指出,他对“天地图”的卫星图片与Google earth的图片进行对比后认为,国家测绘局“天地图”使用的卫星地图,很可能是来自美国 DigitalGlobe公司的图像信息,而并非自主知识产权的图像信息。

  针对网友的质疑,国家测绘局有关人士回应,“天地图”自主知识产权指的是 “服务软件”而并非 “数据资源”,“天地图”卫星图像确实来自商业卫星。在地图显示界面上,包括Google地图在内的所有商业地图,都会在地图的左下角或右下角注明地图数据来源(如DigitalGlobe或Mapabc等),而“天地图”却不在地图上注明数据来源。

  用户通过对比发现,“天地图”的卫星图片与Google earth图片有很多细节一点不差,不同的地方也能在历史状态中找到完全相同的图像。国家测绘局表示,卫星地图并非来自中国的自主支持产权,而来自商业卫星。卫星图像来自商业卫星也无可厚非,但新上线的“天地图”在图像更新上也并没有打败商业对手,一些地方的卫星图片甚至是Google几年前用过的旧图。

  三维界面与谷歌地图几乎一模一样 立体感不强

  三维地图整个界面都与GoogleEarth几乎一模一样,右侧的导航连图片样式都完全一样。所有国家的名称都被按照不同曲率放置在“地球”上,支持鼠标拖拽及滚轮缩放。

  有网友评价说,“天地图”的三维地图实际上就是Google Earth软件的翻版。网友评价天地图的三维功能时说,和Google Earth相比,三维地球也会在“升、降”过程中实时显示市县标识,不过由于反应速度太慢,常常是早已过了相应高度,标识却仍未显示。

  在天地图中在山脉附近点 “平视”,这个三维地图看上去立体感不强。在丘陵地区,高度差在100m左右的,根本显示不出地面的起伏感。而在Google Earth下,在山脉附件点平视,会看到一个立体感很强的地图,山脉的起伏和高低都看得出来,两者使用体验相差很大。

  仅适用IE浏览器 反应速度慢

  “天地图”使用的三维模式地图需要安装单独插件才能进行,如要使用用户需安装一个多达9M的插件,且搜狗、火狐、chrome等非IE内核浏览器均不被支持。

  试用过“天地图”的用户,大多数都会提到“速度太慢”这个问题。有网友写道:“天地图”的访问速度非常慢,一个地图页面有时能打开,有时打不开,地图加载速度非常慢,有时候几分钟都打不开,速度上远远不及Google和百度地图。通过对比了“天地图”和Google地图分辨率较高的细节图发现,天地图在速度上与Google地图“在同一分辨率下平均要比Google地图多花2-3秒才能显示”。并且在使用天地图过程中,占用过多进程,导致用户电脑运行缓慢,在用户体验上不及百度地图和Google地图。 “天地图的速度远远无法达到Google Earth那种流畅顺滑的体验。 ”

  水立方、鸟巢等搜索结果却无一命中

  为求证上述说法,记者实际体验了一次该网站的地图服务。在街道地图模式下,相关地理信息确实很详尽,包括街道办、附近的咖啡馆、路名一应俱全。但当搜索水立方、鸟巢等常见地理位置时,搜索结果却无一命中。此外,有些地名、行政区域名沿用旧称,如浦东和南汇合并后,“南汇区”仍然赫然出现在搜索结果之列。

  记者前天下午致电国家测绘局时,对方表示相关负责人在外出差,暂不方便接受采访。而随着质疑声增多,国家测绘局昨天终于正式出面回应,“天地图”卫星图像确实来自商业卫星,“天地图”自主知识产权指的是“服务软件”而并非“数据资源”。

  虽然谷歌尚未就此表态,但分析人士认为,目前谷歌地图还没有获得国家测绘局的相应牌照,而“天地图”的大部分功能都和谷歌地图类似,最坏的结果可能是谷歌地图反而“被出局”。
