The materials that are featured here illustrate my cartographic and geo-spatial work both as they currently exist and as I continue the learning process and transition into the field of web-based geospatial analysis and web-mapping.
These projects illustrate examples of common web-mapping and geo-visualization work as part of my lab work for the graduate certificate in the New Maps Plus program at the University of Kentucky.
Content on this page will change as I develop and create more maps showing a variety of geo-spatial topics. Stay tuned and visit this page often!!
This project is the culmination of lessons and techniques learned in MAP 673, Design For Interactive Web Mapping. The map includes a wide variety of user interaction elements that include check boxes to turn on/off specific point location layers, marker clustering which aggregates large numbers of locations into one marker at a given scale, ability to drop a marker to designate a travel starting point, and the ability to click on a second point location to determine the distance (in miles) and time (by walking, biking, driving) to travel to the destination point.
Several interactive elements that give the user the ability to select various data attributes and have the map dynamically update. User interaction is one of the most important differences between traditional static maps and web-based maps and the ability to change the map not only offers new possibilities for understanding the information, but It also makes engaging with a map more interesting and rewarding: it's fun!
This project synthesized a variety of tools, techniques, and methods throughout MAP 671, Introduction to New Mapping. Key lessons learned include:
This project involved creating a web page to feature and describe Devils Tower National Monument in northeastern Wyoming. In addition to a two-column layout that provided text and graphics describing the geologic and historical nature of the landmark, the web page includes a dynamic map created using Mapbox Studio. This project involved initially acquiring data from the United States Board of Geographic Names (GNIS), working with Mapbox Studio to create a baselayer, add custom layers (points), specifying the map position, and styling the label visualization with data conditions.
The focus of this project was to provide multiple user interaction elements to explore the data within the spatial and temporal context of unemployment rates in Oregon counties and more broadly, the entire state.
The focus of this project was to provide user intaction elements to explore homeownership data within the spatial context of Kentucky counties.This map was built using custom Javascript code drawing upon the Leaflet Javascript Library as well as CSS and HTML styling rules.
This map was built using Javascript code drawing upon the Leaflet Javascript Library as well as CSS and HTML styling rules.
This map was created using JavaScript drawing upon the Leaflet Javascript library, Leaflet, CSS, and HTML, Leaflet's marker cluter library, and GeoJSON.
Data source(s): National plugIn electric vehicle infrastructure analysis
The focus of this project was to show some select recreational points of interest such as parks and bike trails in relation to other key geographic locations important to outdoor activity such as public bathrooms and cafes in Dupage County, a western suburb of Chicago.
This proportional symbol map shows the relative magnitude of green house gas emissions (GHG) in 2015 by large facilites in Wisconsin. Data are shown by fuel combustion and process emissions. The use of proportional symbols was the better choice to illustrate the amount of Co2 since this is based on an exact point location. Proportional maps are also best suited when showing magnitudes, or amounts of some numerical phenomena relative to other locations.
This map was built using Javascript code drawing from Leaflet Javascript Library as well as CSS and HTML styling rules.

This map was shows the geographic distribution of home ownership in Kentucky by county.
This map was created using JavaScript, Leaflet, CSS, and HTML.
The goal of this map is to visualize those areas in Centre County, Pennsylvania that meet specified criteria. More specifically, the analysis will be used by the Centre County Planning Office to explore a proposed biological reserve system within Centre County. Areas that meet specific criteria would be protected based on a variety of factors including the number of different plant and mammal species and habitat quality. The map produced from this geospatial analysis will assist the decision making process of government officials in evaluating the proposed biological reserve system. This map illustrates multiple variables related to land use, habitat population, and transportation planning
One of the challenging, but also practical elements of this lesson was working with both vector and raster data. Vector data include such phenomena as points (specific locations), lines (highways and roads), and polygons (park boundaries, habitat areas, zoning districts). Raster data represent a continuum of some phenomena such as temperature, climate, or elevation and are represented by cells that have some value and comprise a grid or matrix-like layer. Working with raster data requires an understanding that the cell size of a raster layer can affect the analysis process and can affect the granularity of the level of detail of layers.
Project criteria were defined as:
The map was created using ArcGIS as well as U.S. Census and Pennsylvania state and county level data.
This map was built using Javascript code drawing upon the Leaflet Javascript Library as well as CSS and HTML styling rules, and converting a Google travel route to GeoJSON format.
