如何有效搜索地图上的兴趣点（POI）标记
At Booking.com we’re passionate about making the life of our users easier by providing the best property search capabilities. We want our users to have all the information to choose the best accommodation. It’s probably no secret that the location of the property is one of the most important criteria when choosing an accommodation, as it’s a major part of the trip experience.
在Booking.com，我们热衷于通过提供最好的物业搜索功能，使我们的用户生活更轻松。我们希望我们的用户有所有的信息来选择最好的住宿。在选择住宿时，房产的位置是最重要的标准之一，这可能不是什么秘密，因为它是旅行体验的主要部分。
Booking.com map feature is a powerful tool as it provides location information in a very visual way. In just a few seconds users can determine whether or not the property is in their preferred location. However, usually it’s not enough just to see the location of the property itself. It’s also important to show the location of the most interesting places to visit during the trip. How far are they? How easy is it to get to them from the property?
Booking.com的地图功能是一个强大的工具，因为它以一种非常直观的方式提供位置信息。在短短的几秒钟内，用户可以确定该物业是否在他们喜欢的位置。然而，通常仅仅看到物业本身的位置是不够的。显示旅行中最有趣的地方的位置也很重要。它们有多远？从房产到这些地方有多方便？
To help our users answer these questions, besides the property markers we also display so-called point-of-interest (POI) markers. As the name suggests, these markers highlight places of interest for travelers, such as beaches, ski resorts, landmarks, as well as cities and airports, all of which give a better understanding of the property’s location to the user.
为了帮助我们的用户回答这些问题，除了房产标记，我们还显示所谓的兴趣点（POI）标记。顾名思义，这些标记突出了旅游者感兴趣的地方，如海滩、滑雪场、地标，以及城市和机场，所有这些都让用户更好地了解房产的位置。

When a user opens the map, usually a specific area, called a bounding box (BBox), is visible. Technically speaking, a BBox is a rectangle, the corners of which are represented by 4 geo points:
当用户打开地图时，通常可以看到一个特定的区域，称为边界框（BBox）。从技术上讲，BBox是一个矩形，它的四角由4个地理点代表：
