谷歌地图和谷歌地球应用程序
我想开发一个应用程序，根据一些常量（例如距海岸的距离、房产前面的道路宽度、所在的社区等）来查找房产的价值 - 我将要使用的常量必须插入到该应用程序（我想使用一些可以制作带有点、线、区域和地理编码信息的kml文件的工具）和变量，我将通过一系列表格从用户那里获取τo。要成功计算一个值我需要进行空间查询（例如一个点到该多边形的距离是多少？）
是否可以使用谷歌地图或谷歌地球开发这样的应用程序，或者我必须使用GIS（ESRI，Manifold等）进行开发）。此外，地图和地球应用程序的可能性之间有什么区别？
谢谢
I want to develop an application to find the value of a property based on some constants(such as the distance from the shore,the width of the road in frond of the property,the neighborhood that is located to etc) -constants that i will have to insert to that application (i guess with some tool that can make kml files with point,lines,areas and geocoding information) and variables which i will have τo take from the user through a series of forms.To succesfully calculate a value i need to make spatial querys (such as which is the distance of a point from that polygon?)
Is it possible to develop such an app with google maps or google earth or i have to develop with the use of an GIS(ESRI,Manifold etc).Also which is the difference between the possibilities of the resulting apps with maps and earth?
Thank you

Bill Chadwick 为 Google 地图提供了一些 Javascript，可以计算某个点与聚。请参阅此页面的底部。
Bill Chadwick has some Javascript for Google Maps that calculates the distance of a point from a poly. See the the bottom of this page.
