Geospatial technology is a collecting term of tools used in the science of "where" and analysis of the environment in totality. These tools are useful in answering the questions:
What is at.....? - Locational question
How has it changed......? - Trendy question
Which data are related.....? - Relational question and
What if.......? - Model based question
The above capabilities makes geospatial technology invaluable in all professions including environment, agriculture, health, surveying, business and asset management.
Selected Teaching Materials
Digital Elevation Model for landscape analysis (slope, contours, aspect & visibility)
Landscape contour extraction which is useful in assessing soil erosion potential, infrastructure development siting, flooding potential, e.t.c
Landscape percent slope rise
Landscape aspect (direction the slope is facing)
Generation of 3D from 2D images
Landscape for visibility analysis at point marked with a red dot on a 3D landscape
Visible area at 2m above the ground (26.37%) of the area is visible
Visible area at 50m above the ground (58.31%) of the area is visible
FAO EcoCrop model output of cotton growing areas in Kenya based on 2018 climate (Color information is on the right table)
This data is derived from modelled cotton growing areas and Kenya's 2009 census population & household (the census data was projected to 2018). Using this data, both county and national governments and other stakeholders can target the areas with "Excellent" & "Very Suitable" suitability levels to promote cotton production. The total numbers of households and the combined areas in the two suitability levels is useful information to run an informed economic analysis of cotton crop production in the country (it provides the size of land and the number of potential farming households).
Basic map production (this is Kakamega forest showing data sampling stations & points for a specific research).
This is analysis of slope in four sublocations in Nandi county as per the Agriculture Act Cap 318. (Note the details in the tables).

Selected Research Materials
Land surface temperature extraction from landsat satellite imagery dated 12th June 2009, 7:43 am GMT.
Kakamega Forest camping ground multi-criteria suitability analysis based on five factors
Modelled mosquito niche spatial distribution changes in Kenya's highland
Kenya's monthly spatial trend of rainfall distribution
Kenya's monthly spatial trend of MODIS NDVI distribution
The future climate based changes of rangeland vegetation suitability
Grass biomass production trend (2001 - 2015)
Example of farm mapping
Mapped land use land cover data & details of the example farm
ALOHA model output showing details of Households, Population, Schools, Area and Major crop affected by the dispersed pollutants at different concentrations. Such data is useful in research and in disaster preparedness and management. In this example, it is possible to estimate the size of area requiring soil remediation among other useful information.
Modelled climate based changes in suitable sorghum production areas in the future
Village-level GIS application to aid development decision making through project prioritization by location based on distance from households. In this example, where to extend power grid, road network, water network and build new schools based on distances from households can clearly be identified.
