Embodiment Construction
[0020] Such as figure 1 As shown, a paddy field classification and information extraction system in Northeast China of the present invention includes four parts: a data preparation module, a paddy field classification module, an attribute addition module and a paddy field extraction module.
[0021] (1) Based on the collection of the current land use map of the study area at the same time period, that is, the DLTB layer of land types and patches based on the second land survey held by the Ministry of Land and Resources, high-resolution remote sensing images with a resolution of 1-8m, and land consolidation planning data Because different data sources have different spatial reference systems, multi-source data superposition has deviations, so with the help of ArcGIS, ENVI and other software, use the DLTB layer of land survey as the benchmark data to analyze high-resolution remote sensing images, land consolidation planning, etc. The data is geometrically corrected, and the data...
