An IPHC survey map

IPHC Setline Surveys


The International Pacific Halibut Commission (IPHC) conducts annual surveys that collect standardized data used for halibut stock assessment. This interactive web map displays the station locations and regulatory areas where the annual setline surveys occur. The data used in this exploratory analysis are from 1998 through 2015, and include total count and weight of fish at each survey station. The code for this web map can be viewed on Github.

A map of Kenyan attrition rates

Student Attrition Rates


This map compares 2014 Kenyan primary (grades 1-8) and secondary (grades 9-12) enrollment totals of girls and boys by county. Data for this analysis were collected as part of the 2014 national schools census. The size of each circle on the map corresponds to countywide enrollment, where larger circles represent greater enrollment totals.Each symbol is apportioned and assigned a color by gender.The code for this web map can be viewed on Github.

U.S. Power Plants


This interactive bi-variate web map displays nuclear, hydroelectric, and solar power plants within the United States, symbolized by fuel source and energy output. The proportional circle symbols indicate the amount of power produced from one fuel source. The user can click any blank area on the map to visually filter power plants within 500 kilometers from the click location, then click on a power plant location circle to display its attributes and distance from the original click point. The code for this web map can be viewed on Github.

Historic Appalachian Trail


This print map combines the use of contemporary geospatial technologies with historic cartography. The Appalachian Trail is overlaid with a georeferenced copy of the 1957 Landforms of the United States map by Erwin Raisz. This map was created by georeferencing ground control points and graticule interseactions dispayed on Raisz' historical map with a present-day graticule grid.

Application: QGIS
Data Sources: David Rumsey Map Collection, Appalachian Trail Conservancy and Natural Earth

Bus Stop Friendly Berlin


This ¾ kilometer buffer analysis of bus stop locations displays one of the many excellent public transportation options available within Berlin, Germany. All data, including bus stops, roads, boundaries and water features were downloaded from OpenStreetMap and designed in QGIS.

North American Breweries


A hexagonal binning technique (hexbins), was used to create this high density heatmap. Brewery point location data were aggregated into individual 50-kilometer diameter hexagonal polygons and symbolized according to quantity. Denver, Colorado has the highest density of breweries in North America.

IPHC Statistical Harvest Data


The International Pacific Halibut Commission (IPHC) studies the management of the stocks of Pacific halibut (Hippoglossus stenolepis) within the Convention waters of the United States and Canada. Commercial fishing is still permitted under certain circumstances within Glacier Bay National Park. This screenshot displays an interactive web map developed for the National Park Service that combines both spatial and temporal IPHC statistical harvest data.

Tlingit Placename Illustration


Glacier Bay, Alaska is the ancestral homeland of the Huna Tlingit. The Little Ice Age, a geologically recent glacial advance reached its maximum extent in the mid 1700s. The geographical placenames associated with the geology of this landscape are still part of today's Tlingit language. This map was designed as an anthropological research illustration and displays the retreating glacier layered over the current geography of the area.
