Retina and LGN

A demonstration written in Mathematica to show the interaction of the retina and LGN on the sampling of image information from the eyes. You can play with the receptive field size to see how the whole “Hybrid Images”… Read More Continue reading

Colorful Visualization of the day

An in-development look at some age judgement data. Not sure what it is telling me yet, but I can’t let that stop me from looking at it? Continue reading

Volumes

Doing a little work on a fluid-flow project with some folks here- Wrote a volume renderer for it, basically re-visiting work I did in 1986 at The OSU CGRG, which eventually was applied to stuff we did with the volume… Read More Continue reading

Building a better trail map…

  For a long time, the trail map for the old Skidmore College North Woods Trail Map has been not up to my personal cartographic standards. Originally developed by Bob Jones and Alex Chaucer a few years ago, multiple versions had been edited and what was the North Woods map had lost it’s original lustre and […] Continue reading

Researching Data Analytics for GIS

This summer in the GIS Center we are expanding the center’s capacity as we research data analytics in the context of GIS and data science related programming languages. To this end, we are focusing on two emerging geospatial tools, ArcGIS Online and CartoDB for web based mapping applications, as well as adopting R, Python, and SQL for more in depth data analysis. In order to accomplish our goals, we currently have one main project that will be a collaboration with another summer student researcher that focuses on CartoDB and applying SQL queries for a local community project called the Sustainable Saratoga Urban Forestry Project. We will also be learning about database design through an online textbook and tutorials. Additionally, we will be utilizing online ESRI training to explore the Python capabilities in ArcGIS Desktop, while also utilizing CodeAcademy for Python training, and an online course through the University of Michigan called Programming for Everybody (Python). For R training, we are focusing on a series of courses through Johns Hopkins called the data science specialization, which introduces a data science toolkit, and quickly focuses on R for working with large datasets. We may also supplement with a course offered through codeschool […] Continue reading

Highlight on Student-Faculty Research: Rebuilding a Political World with GIS

Note: Click on map above to view animation in its own window. History Professor Eric Morser and Skidmore student Niki Deininger (Class of ’15) have teamed up to make unique historical maps that recreate the political setting of a New Hampshire county in the 1830s. Some fascinating maps have been produced by this team using ArcMap and a GIF animation program. CartoDB and Geocommons were also evaluated for possible map data visualization opportunities. The maps will be used in Professor Morser’s book, The Fires of New England: A Tale of Power and Protest on an American Frontier. This book focuses on a single document signed by twenty men in Cheshire County, New Hampshire, in 1834. According to these men, lawyers had seized control of the state government, taken advantage of the state constitution, undermined democracy, and threatened to destroy the revolutionary dreams of America’s founders. In response, the twenty men proposed that universal education and a well-schooled population could thwart the deceitful efforts of the attorneys and judges and revitalize the state’s revolutionary heritage. Professor Morser attempts to locate this single document in its larger historical context and explain why these men produced it when they did. With the help […] Continue reading
