Research and Development on Information System of Grading, Classifying and Pricing Cropland

Based on principle of grading, classifying and pricing agricultural land and composite type geography information system (COMGIS) and computer technology, the prototype of general information system of grading, classifying and pricing cropland (ALEIS) is developed. ALEIS is suitable for Chinese conditions for evaluating cropland. This system has 9 big modules including file, view, picture layer, object, layout and database, grading, classifying, pricing, windows and help etc. It has powerful functions in managing attributive data sets and spatial data sets, grading, classify and pricing cropland and outputting achievements etc. The interface of ALEIS is friendly, and the operation of the system is simple and convenient. It can realize automation in grading, classifying and pricing agricultural land, and offer the friendly and convenient computer business management tool for land and government administrative department of different levels.
