Research Topic Description, including Problem Statement:
The goal of this research is to support early warning of food security issues by improving regional and global crop classification from remotely sensed data. Because of the global scale of modern agriculture, a limited number of crop types (e.g., wheat, barley, corn, soy, rice) dominate the world’s food supply. Within each type, however, these crops vary widely due to different cultivars, growing conditions, and management practices. This variation makes it difficult to construct the representative ground truth data required for accurate and automated regional or global crop classification. Currently, crop classification training data are highly localized and limited in distribution which can result in poorly captured variance of a crop across larger spatial scales. There is a need for research into how each crop type can vary across space and how to optimally sample training and testing data across different regions, climatological regimes, and topographic conditions in order to improve regional and global crop classification from remotely sensed data.
Example Approaches:
Example approaches could include, but are in no way limited to:
Using data mining and clustering approaches to separate widely distributed regional samples into unlabeled classes, interpreting the differences between such clusters, and determining geophysical, biological, and anthropogenic drivers of those differences.
Combining multiple data sources to determine driving conditions of variation and modeling how a priori conditions can forecast crop “appearance” (e.g., phenological state at a given time, field pattern, normalized difference vegetation index response) from remote sensing data (e.g., synthetic aperture radar, multispectral).
Using remotely sensed data in conjunction with field samples to determine how small scale variations coalesce as larger regional patterns for different crop types.
Developing methods to estimate how a crop in a specific region or locale might vary from generalized spectral, spatial, or temporal signatures.
