Google Earth engine (GEE) - ghsl global population grid dataset 250 meter resolution

Recently, I found a giant cow's artificial intelligence learning website , Click to jump to the website ：

Preface – A course of bed length artificial intelligence

There are a lot of introductions about basic manual work above , It is of great help to students who are getting started with AI .

 

  Officially start data introduction ：

GHSL It depends on the design and implementation of new spatial data mining technology , Allow automated processing and extraction of analysis and knowledge from large amounts of heterogeneous data , These data include ： The global 、 Fine scale satellite image data stream 、 Census data and population sources or voluntary geographic information sources .

This data set describes the distribution and density of the population , Expressed in the number of people per cell , For reference periods ：1975、1990、2000、2015.

The resident population is estimated by CIESIN GPW v4 Provide . These are decomposed from census or administrative units to grid cells , From each corresponding period in GHSL The distribution and density of buildings mapped in the global floor provide information .（ See “250 m Development of a new open and free multi temporal global population grid at resolution .”）

The dataset is in World Mollweide Projection (EPSG:54009) Generated in the .

Global human settlements layer (GHSL) The project was approved by the European Commission 、 Support from the joint research centre and the regional and Urban Policy Directorate .GHSL Generate new global spatial information 、 Evidence based analysis and description of the knowledge of human existence on earth .
