I m 考察一个制图项目的一些选择(网站,可能以超文本5Canvas为基础)。 理想的情况是,我们正在建立一个导航图(即谷歌地图),它有我们自己非常简单的图像(不是卫星),但我们正在研究如何获得国家/城市线,或许还有其他重要特征。 是否有任何人知道含有这种数据的良好数据库或项目与纬度有关? 或者我们看看着这些路线本身的可能性吗?

最佳回答

有许多选择,但确实取决于你所期望的准确程度、详细程度以及哪些国家。

One of the first places you ll want to look is open geo:

http://opengeo.org/“rel=“nofollow”http://opengeo.org/

这些幌子与所有开放源地的地理结构有联系,这些地理结构可以提供多少。

第二,是两性平等问题顾问小组:

http://www.osgeo.org/“rel=“nofollow”http://www.osgeo.org/。

同样,这些宝库还设有预制工具包,并与大部分数据与安检系统链接;现有应用。

一旦你们走到这里,你很可能需要开始研究像副秘书长这样的国家组织:

以及

http://egsc.usgs.gov/isb/pubs/factsheets/worldmaps.html

很可能也想对联合王国的弹药调查等一些国家的具体数据集进行调查:

以及 the USA Tiger data sets:

最后,你可以看一看“开放街道地图”(以及其他类似产品)。

http://www. openstreetmap.org/

开放的街道地图最初是为了覆盖联合王国,但现在似乎至少遍布欧洲(甚至可能遍及全世界)。

This is all I can remember off the top of my head at the moment, but one other tip I ll give, sites belonging to the top GIS software providers such as ARC-GIS & Mapinfo all have lists of mapping data providers on their websites, 以及 some even have free data available too, an afternoons browsing should uncover you a lot of sources.

问题回答

http://openstreetmap.org should have what you need.
