Cartography

Work showcasing a range of applications.

Web Map Development

This example demonstrates an interactive web map developed to visualize spatial data dynamically. It demonstrates real-time data layers, user interaction, and spatial storytelling to support analysis and decision-making.

Spatial Modelling

Air Pollution Exposure

This map illustrates air pollution exposure across Central Nakuru County. The Central Nakuru CBD is highlighted in purple and red, indicating high pollutant concentrations due to dense urban activities and traffic emissions. Rural areas to the east in Nyandarua County are shown in yellow and green, reflecting lower pollution levels and cleaner air.

Spatial Distribution Analysis

This map presents the spatial distribution of service centres within Nakuru West. The analysis highlights facility density, clustering patterns and underserved locations, helping planners assess accessibility and infrastructure allocation.

Urban Heat Island Analysis

This example demonstrates urban heat intensity in Kisumu City. Red areas indicate intense heat concentrations associated with dense built-up environments while vegetated zones exhibit lower surface temperatures.

Land Cover Change Detection

This is an example of change detection analysis, which compares imagery from different years to identify vegetation loss, regeneration, urban growth, and land cover transitions. These methods support environmental monitoring, planning, and sustainable resource management.

Using accident records, kernel density analysis identifies high-risk corridors and hotspots. Similar methods can be applied to flood risk mapping, environmental hazards, disease mapping and vulnerability assessments.

Site Suitability Analysis PROJECT

A featured project completed in 2024 at the Directorate of Resource Surveys and Remote Sensing (DRSRS), focusing on land use planning and site suitability analysis for industrial development in Nyeri County.
