Hi, I'm Rainer Martens.

Welcome to my GIS portfolio page. Check out my projects below!

Ornamental Pear Tree Density in Charlotte, NC

Interactive web map based on my master's thesis research on the cultural and historical biogeography of Pyrus calleryana cultivars, trees popularly planted in the southern region during a time of suburbanization. Created with Javascript, Leaflet, chroma.js, leaflet.heat, Bootstrap, and data from the Charlotte urban tree canopy inventory.

Gender Equity in Kenyan Primary Schools

This interactive web map compares Kenyan primary school enrollments for grades 1-8 by gender for the year 2014 and shows enrollment distributions by county. The map was created with Javascript, Leaflet, and Bootstrap, using data from the Kenya Open Data Portal.

Flood-Prone Infrastructure in Eastern Kentucky

These maps and visualizations analyze flood-prone infrastructure in the Eastern Kentucky watershed of Robinson Creek using ArcGIS Pro and LIDAR data. This work was created for the course GEO509: Workshop in Geospatial Technologies.

Renewable Energy Powerplants

This interactive web map shows power plants in the U.S. that generate electricity from wind, solar, and geothermal sources. It was created with Leaflet and Javascript using data sourced from the U.S. Energy Information Administration.

Waterways of Tennessee

This static map visualizes waterways in the state of Tennessee and was created with QGIS.

About me

Hi, I'm Rainer. I'm a Geographer and map maker. I love thinking spatially, from examining canopy cover to looking at patterns of urban development. My training is in geography and I have a graduate certificate in Digital Mapping from the New Maps Plus program at the University of Kentucky. I currently work for the U.S. Forest Service as a GIS Resource Assistant.

I'm passionate about learning new things, tackling challenging problems with creative solutions, and sharing my knowledge with others. Also hiking and my dog!
