Non-Student Research

NEON Data Exploration:  The National Science Foundation’s National Ecological Observatory Network (NEON) collects and provides long-term open access data to explore and understand continental ecosystems. The KU Field Station is the satellite site to the Konza Prairie which represents the Prairie Peninsula domain.  During peak productivity, NSF’s Aerial Observation Platform collects LiDAR, hyperspectral imagery, and high-resolution aerial imagery on an annual basis.  Numerous indices and data products are then derived and made available through the NEON Data Portal. To explore data availability, quality, and utility, KansasView has compiled multi-year datasets for the KU Field Station that will be publicly available. These data will be presented and shared with researchers in an effort to explore potential future research opportunities.

Potential Wetland Area (PWA) Database: Using LiDAR-derived digital elevation models (DEMs) and terrain layers, a topographic wetland identification process (TWIP) has been developed to map potential wetland areas in Kansas. KansasView is leveraging and building upon existing mapping efforts to complete the PWA database for Kansas. The data will soon be available on the Data Access and Support Center (DASC), the state’s repository for geospatial data at To access data you will need to create a user login profile. To find the PWA database, go to Catalog–>Environmental Resources–>Potential Wetland Areas.

Student Research Grants

KansasView continues to offer small research scholarships to students attending our consortium institutions. Below is a summary of recently funded student research projects

Hilda Onuoha, Ph.D. Candidate in the Department of Geography at Kansas State University used the KansasView mini-grant to work with Dr. J.M. Shawn Hutchinson on the project titled, “Time Series Analysis of Phenometrics and Long-Term Grassland Trends across the Great Plains Ecoregion Using Moderate Resolution Satellite Imagery“. Below is a summary of the research approach and current activities.

Grazed grassland in the Great Plains Ecoregion in Central Kansas

MODIS MOD13Q1 16-day maximum composite value NDVI image products were acquired for the period 2001-2017 (250 m spatial resolution, n = 391 images). Using the 2011 NLCD product, spatially resampled pixels of the “grassland/herbaceous” class were used to mask MODIS imagery to retain for analysis only those 250 m pixels comprised of a majority of grassland types and within the Great Plains Level 2 ecoregion.

Phenological analysis was conducted using the program TIMESAT and included quality data provided by the MOD13Q1 pixel reliability band.  Temporal decomposition was performed using the Breaks For Additive Seasonal Trend (BFAST) routine which is based on a LOESS driven STL temporal decomposition.  BFAST also models the trend component which permits detection of breakpoints, including when the break occurred and its magnitude. Phenometrics and NDVI/EVI trends data have recently been computed using the Beocat High-Performance Computing (HPC) cluster at Kansas State University. Current activities are focused on additional statistical analysis to better evaluate spatiotemporal trends.

In 2018, the research was presented at the 3rd Joint European Association of Remote Sensing Laboratories and NASA Land use/Landcover Change Workshop. Two publications detailing NDVI and EVI trends over the 2001-2017 period and a summary of current phenological measures of vegetation development are in progress and will be submitted later in 2019.

Gary Kelner, Ph.D. candidate from Fort Hays State University used a KansasView mini-grant for his research on Karst Feature Predictability Modeling in southern Kansas. Landsat 8 and LiDAR data were used in the predictive model. The funding helped in the reconnaissance of the karst features to test his model. Gary presented his research at the Geological Society of America 2019 Annual Meeting in Phoenix, Arizona in September 2019.
