确定所在位置的地形类型 [英] Determine type of terrain at location

问题描述

我正在尝试确定任意位置的地形类型.例如，如果我使用Google Maps，我可以通过地图上显示的颜色直观地看到什么是森林，建筑面积和水域.

I'm trying to determine the terrain type at an arbitrary location. If I make use of Google Maps for instance, I can visually see what terrain is forest, built up areas and water for instance by the colour displayed on the map.

我正在尝试查看是否可以使用某种API调用来获取此基本信息.我不需要非常精确，也不需要确定确切的地形类型(因此，像Corine Land Cover这样的东西实在是太过分了).我将每隔几分钟就要提出许多这样的要求.我已经找到了一个早在3年前就问过的问题真的解决了，我希望现在有所改变.

I'm trying to see whether there's any sort of API call I can use to get this basic information. I don't need it to be highly precise and I don't really need to determine the exact terrain type (so stuff like the Corine Land Cover is pure overkill). I'm going to need to make a number of these requests every few minutes. I've found a previously asked question around 3 years ago which wasn't really resolved, I'm hoping that there's been a change now.

有什么我可以使用的吗?我实际上正在考虑自己阅读显示的地图图块并获取像素颜色，但是如果有更简单的方法，我将不胜感激.

Is there anything I can use? I'm actually considering reading the displayed map tile myself and grabbing the pixel colour, but I'd appreciate if there was a simpler method.

推荐答案

似乎他们没有提供执行此操作的API.

It doesn't seem like they provided the API to do that..

一种解决方法是使用其静态地图API.

A work around would be to use their static maps API.

基本上，在关闭除水和绿色之外的所有东西之后，您会得到类似以下的内容:

basically after you turn off everything but the water and greens, you get something like this:

您可以将尺寸设置为1px x 1px，放大并检查该图像的颜色以确定该位置区域的类型.

you can, make the size to be 1px by 1px, zoom in, and check the color of this image to decide the type of area of this location.
