CropEx Web-Based Agricultural Monitoring and Decision Support
- Monday, 24 October 2011
Changes in crop health are monitored over time.
CropEx is a Web-based agricultural Decision Support System (DSS) that monitors changes in crop health over time. It is designed to be used by a wide range of both public and private organizations, including individual producers and regional government offices with a vested interest in tracking vegetation health. The database and data management system automatically retrieve and ingest data for the area of interest. Another stores results of the processing and supports the DSS. The processing engine will allow server-side analysis of imagery with support for image sub-setting and a set of core raster operations for image classification, creation of vegetation indices, and change detection.
The system includes the Web-based
(CropEx) interface, data ingestion system,
server-side processing engine, and
a database processing engine. It contains
a Web-based interface that has
multitiered security profiles for multiple
users. The interface provides the
ability to identify areas of interest to specific
users, user profiles, and methods of
processing and data types for selected or
created areas of interest. A compilation
of programs is used to ingest available
data into the system, classify that data,
profile that data for quality, and make
data available for the processing engine
immediately upon the data’s availability
to the system (near real time).
The processing engine consists of methods and algorithms used to process the data in a real-time fashion without copying, storing, or moving the raw data. The engine makes results available to the database processing engine for storage and further manipulation. The database processing engine ingests data from the image processing engine, distills those results into numerical indices, and stores each index for an area of interest. This process happens each time new data is ingested and processed for the area of interest, and upon subsequent database entries, the database processing engine qualifies each value for each area of interest and conducts a logical processing of results indicating when and where thresholds are exceeded. Reports are provided at regular, operator-determined intervals that include variances from thresholds and links to view raw data for verification, if necessary.
The technology and method of development allow the code base to easily be modified for varied use in the real-time and near-real-time processing environments. In addition, the final product will be demonstrated as a means for rapid draft assessment of imagery.
