GIS样本数据以测试性能 [英] GIS sample data for testing performance

问题描述

我需要根据空间数据测试查询的性能.我决定使用sql server和geometry数据类型.

现在我需要样本数据(例如地图，城市等).您知道我可以用来将其加载到数据库中的任何资源吗?

感谢您的帮助

解决方案

美国人口普查局向公众提供了所有形状文件.看这里: http://www.census.gov/geo/www/tiger/

一旦选择了所需的任何形状文件，就可以使用以下出色的Shape2SQL工具将其导入SQL Server: http://www.sharpgis.net/page/Shape2SQL.aspx

I need to test performance of queries based on spatial data. I decided to use sql server and geometry datatype.

Now I need to have sample data (for example maps, cities etc). Do You know any resources that I can use to then load it into my database ?

Thanks for any help

解决方案

The U.S. Census Bureau makes all of their shape files available to the public. See here: http://www.census.gov/geo/www/tiger/

Once you have picked whatever shape files you want, you can import them into SQL Server using the excellent Shape2SQL tool found here: http://www.sharpgis.net/page/Shape2SQL.aspx
