推荐答案

其中许多人都使用Google Maps(我相信Bing/Microsoft也有类似的产品). 使用C#和JavaScript在Google Map上显示数据 [此 [

Many of them use Google Maps (I believe Bing/Microsoft have a similar offering). Show Your Data on Google Map using C# and JavaScript[^].

As you will see that article uses Lat./Long. so you need something to translate from a postal code to Lat/Long. This[^] article claims to have code that will do that (I haven''t tried it).

Then all you need is an enormous database of restaurants/amenities filterable by country, postcode and category. I have no doubt that such services exist somewhere out there and I also have no doubt that most of them charge for use.

The first two links should get you started though and you''ll probably get some hints about the last part as you research stuff for those.

有一些专业的制图公司来进行数据库构建并将其出售给其他公司用于其产品.

该信息也来自类似的内容；
电话簿
黄页
公司注册资料
等

您也可以用老式的方式进行操作，即步行/乘车的人并手动写下信息.

然后，所有这些数据都将通过专业数据挖掘工具进行混搭，以确保有效性和准确性.

然后剩下的就是卫星导航数据库的内容.

There are specialist mapping companies that perform the database building and sell these on to other companies for use in their products.

The information is also taken from things like;
Phone Books
Yellow Pages
Companies Registers
etc.

You can also do it the old fashioned way, i.e. person on foot/in car and writing down the information manually.

All this data then gets mashed through specialist data mining tools to ensure validity and accuracy.

What you are then left with is the likes of your sat nav database.
