land use survey

基本解释

The study on the change patterns of linear features in remote sensing imagery is a very active research field in land use survey worldwide.
一般线状地物在遥感影像中的变化规律是目前国内外土地利用调查中非常活跃的研究领域。
The final surveyed data of land use is of high precise and practice and can meet the needs of the land use survey at county level in our country.
最终获得的土地利用调查数据具有较高精度和实用价值，能满足我国县级土地利用调查的要求。
