1. Monitoring Harmful Algal Blooms with Landsat 8, Funding source: USGS. John Schott is the PI on the Landsat Science Team. Under that project I am supervising a graduate student who is investigating the application of Landsat 8 to monitoring cyanobacteria blooms. We are using the Look Up Table and spectrum matching approach to assess accuracy for cyanobacteria bloom identification and quantification. We are also testing for band combinations that may be added to Landsat 10 to enhance the detection and monitoring of cyanobacteria blooms in inland and coastal waters.
2. DDDAS for Vehicle Tracking, Funding source: AFOSR. We are combining image analysis, vehicle motion models, crowdsourced data, and adaptive sensing in a dynamic data-driven application system (DDDAS) for object tracking. Our test data is high resolution video generated by DIRSIG. This project is ongoing, now with Matt Hoffman as PI. The following are some papers from this project:

Some Past Projects
1. Promoting spatial thinking in natural resource management through community mapping: the case of urban and rural secondary schools of Rwanda, Funding source: Innovation for Education (MINEDUC and UKAID). We are introducing spatial thinking into Rwandan high school curriculum in two target schools by teacher training and by providing mobile technology mapping applications to the students and encouraging them to explore and map their own communitites. Through rigorous assessment of student performance on spatial thinking assessments, we will quantify improvements in spatial thinking ability while also monitoring innovation by students and teachers alike. The following is our initial contribution from this project:
Tomaszewski, B.; Vodacek, A.; Parody, R.; Holt, N. 2015. Spatial Thinking Ability Assessment in Rwandan Secondary Schools: Baseline Results, Journal of Geography. 114(2):39-48, doi:10.1080/00221341.2014.918165.
A specific data product initiated by the Lake Kivu project funded by the MacArthur Foundation (see below) and continued with support by this project is a set of land cover classifications for the Lake Kivu Region. These classification maps were produced from the Landsat archive using a method for compositing a time series of images as a means to minimize cloud cover. The results are classification maps for 1988, 2001, and 2011 and can be downloaded at the links below. When unzipped these files contain a folder with a set of files suitable for ingestion and display of the classification map with GIS software. There is also a pdf version of the classification map. NOTE: These files were updated 11 May 2015 with the results from an improved classification, the addition of the pdf file, and minor changes to the legend. Please replace files downloaded prior to 11 May 2015 with these files.
2. Dynamics of the Lake Kivu System: Geological, Biological and Hydrographic Impacts on Biodiversity and Human Wellbeing, Funding source: John D. and Catherine T. MacArthur Foundation. A multidisciplinary of the past history and current status of the Lake Kivu System. The work combines baseline surveys including sediment cores, seismic profiling, earthquake monitoring, and terrestrial remote sensing to understand past change at a variety of spatial and temporal scales. From this new understanding of the dynamics of the system we gain a better understanding of system component interactions and potential scenarios for future change. The following are some published papers from this project:
