Understanding Layers in Maps

The Maps app is an inbuilt module of the monitoring and evaluation system that provides the user with a visual representation of a part, or an entire area typically represented on a flat surface. The app provides a uses Layers to visually represent your data in each area at a given period. Below are the layers available in the platform.

• Organization Units Layer

This layer describes the visual representation of the Communities, Districts and Regions in a geographical area.

• Population Layer

This layer is generated using Google Earth Engine to provide an estimation of the number of people living an area over a given period. There are multiple aggregation methods to help further describe the population in that area.

• Population Age Groups Layer

This layer is generated using Google Earth Engine to provide an estimation of the number of people living an area, grouped by age and gender in a given period. There are multiple aggregation methods and group selections to help further describe a specific section of the population within that area.

• Building Footprints Layer

This layer generated from Google Earth Engine describes the visual outlines of buildings for the chosen region, district, or community. 

• Elevation Layer

This layer is generated to provide visual indications of areas that are above-sea level. The elevation data is calculated on Google Earth Engine for that selected area. There are multiple aggregation methods to help better describe elevation in each community, district and/or region.

• Precipitation Layer

This layer is generated to provide visual indications of rain dense areas. Precipitation collected from satellite and weather stations of the ground. The values (in millimetres) are calculated within a 5-day period. There are multiple aggregation methods to help better describe rain dense areas in each community, district, or region.

• Temperature Layer

This layer is generated to provide visual indications of land surface temperatures collected from satellite. The data will be calculated on Google Earth Engine for that selected area.

There are multiple aggregation methods to help better describe these land surface temperatures in each community, district, or region.

• Landcover Layer

This layer is generated to provide visual indications of the various land covers (savannah, forest, water areas, etc) The data will be calculated on Google Earth Engine for that that selected area. There are multiple aggregation methods to help better describe these land covers in each community, district, or region.
