PopCluster

PopCluster is a QGIS plugin that uses raster population, night-time light and administrative boundaries to generate vector based (polygon) population settlements or else "population clusters".

Plugin options

As of March 2020, there are four available versions of the plugin:

  • Option 1. Plugin developed for QGIS 3.10
  • Archive Plugin developed for HRSL in QGIS 3.4 and 3.2 and plugin developed for GHS in QGIS 3.2

Note! We recommend using a HRSL based version. The GHS based version shall be used only if HRSL is not available for your area of interest.

Installation

Requirements

  • QGIS 3.2, 3.4, 3.10 or 3.16
  • Python >= 3.6 with the following packages installed:
    • PyQt5
    • shutil
    • qgis
    • datetime

Adding plugin in QGIS

Note! Detailed instruction on how to install and use the plugin is available in the "Instructions" folder.

  1. Download the zipped plugin folder onto your computer.

  2. Open QGIS Desktop (proper version)

  3. Click on the "Plugins" menu

    image1

  4. Go to "Manage and Install Plugins..."

    image2

  5. Choose Install from ZIP

    image3

  6. In the window that opens click on the three dots next to the empty field to navigate to where you saved the zipped plugin folder

    image4

  7. Select it and click "Install plugin"

    image5

  8. An installation progress bar will appear on top of the screen

    image6

  9. After the plugin is installed it appear under the "Plugins" menu with the name HRSL Clustering. It is now ready to use!

    image7

Using the plugin

  1. Open the plugin in QGIS

image1

  1. Add necessary input layers
  • The population raster file (HRSL or GHS)
  • The admin boundaries layer for the area of interest (e.g. GADM)
  • The nighttime lights raster layer (VIIRS)

image2

  1. Run the plugin

If succesful, the resulting layer will be added in your workspace. The resulting clusters are attributed the following information:

  1. id - a unique identifier for each cluster
  2. Country - the name of the country/study area
  3. Population - population in defined year (based on HRSL published date)
  4. Area - the area of each cluster (in sq.km)
  5. Nightlights - the maximum value of nighttime light detected in each cluster
  6. ElecPop - the number of people living in areas with detected nighttime light

Sample input/output files are available for Equatorial Guinea here.

Cautions

  • The admin boundaries layer is used to delineate the area of interest and to limit the maximum area of the clusters;therefore it is highly recommended that you choose administrative boundaries that are disaggregated beyond the national borders.

  • The nighttime lights map show anthropogenic light sources and will be used in order to determine the population living in areas with light emitting infrastructures present. It is recommended that you use the cleaned data with outliers removed. These data are only available on a yearly basis and as of March of 2021 the latest version is from 2016.

Supplementary material

  • The methodology behind the plugin is published and publicly available here

  • For any bugs reported please raise an issue on this repository

  • For any additional information please contact the KTH team

  8. An installation progress bar will appear on top of the screen
    image6
  9. After the plugin is installed it appear under the "Plugins" menu with the name HRSL Clustering. It is now ready to use!
    image7
Using the plugin
  1. Open the plugin in QGIS
image1
  1. Add necessary input layers
  • The population raster file (HRSL or GHS)
  • The admin boundaries layer for the area of interest (e.g. GADM)
  • The nighttime lights raster layer (VIIRS)
image2
  1. Run the plugin
If succesful, the resulting layer will be added in your workspace. The resulting clusters are attributed the following information:
  1. id - a unique identifier for each cluster
  2. Country - the name of the country/study area
  3. Population - population in defined year (based on HRSL published date)
  4. Area - the area of each cluster (in sq.km)
  5. Nightlights - the maximum value of nighttime light detected in each cluster
  6. ElecPop - the number of people living in areas with detected nighttime light
Sample input/output files are available for Equatorial Guinea here.
Cautions
  • The admin boundaries layer is used to delineate the area of interest and to limit the maximum area of the clusters;therefore it is highly recommended that you choose administrative boundaries that are disaggregated beyond the national borders.
  • The nighttime lights map show anthropogenic light sources and will be used in order to determine the population living in areas with light emitting infrastructures present. It is recommended that you use the cleaned data with outliers removed. These data are only available on a yearly basis and as of March of 2021 the latest version is from 2016.
Supplementary material
  • The methodology behind the plugin is published and publicly available here
  • For any bugs reported please raise an issue on this repository
  • For any additional information please contact the KTH team

PopCluster
PopCluster is a QGIS plugin that uses raster population, night-time light and administrative boundaries to generate vector based (polygon) population settlements or else "population clusters".
Plugin options
As of March 2020, there are four available versions of the plugin:
  • Option 1. Plugin developed for QGIS 3.10
  • Archive Plugin developed for HRSL in QGIS 3.4 and 3.2 and plugin developed for GHS in QGIS 3.2
Note! We recommend using a HRSL based version. The GHS based version shall be used only if HRSL is not available for your area of interest.
Installation
Requirements
  • QGIS 3.2, 3.4, 3.10 or 3.16
  • Python >= 3.6 with the following packages installed:

    • PyQt5
    • shutil
    • qgis
    • datetime
Adding plugin in QGIS
Note! Detailed instruction on how to install and use the plugin is available in the "Instructions" folder.
  1. Download the zipped plugin folder onto your computer.
  2. Open QGIS Desktop (proper version)
  3. Click on the "Plugins" menu
    image1
  4. Go to "Manage and Install Plugins..."
    image2
  5. Choose Install from ZIP
    image3
  6. In the window that opens click on the three dots next to the empty field to navigate to where you saved the zipped plugin folder
    image4
  7. Select it and click "Install plugin"
