本系统是我参加ESRI大赛的一个作品 主要利用GIS功能对水土流失模型USLE中的各个因子的提取（如根基降雨量站点插值生成等值线，利用等高线生成TIN提取坡度，坡向等）再生成专题图输出。系统包含数据采用的ACCESS,有对数据库的通用操作，以及各种绘图分析，如对年、月、日的降雨量，流量等的图形对比分析等等。系统功能还算比较完善。 是基于VB6.0+ArcEngine9.2开发，皮肤界面用的是Activebar3.0 里面的数据比较大，不便上传，需要的可向我索要。-This system is a competition I took part in ESRI works mainly use the GIS capabilities of the USLE soil erosion model for the extraction of the various factors (such as the foundations of rainfall site, contour interpolation, using contour lines generated TIN extraction slope, aspect, etc. ) and then generate the thematic map output. System contains the data used in ACCESS, there is a common database operations, and a variety of mapping analysis, such as year, month, day of rainfall, flow, etc. graphic correlation and so forth. Relatively perfect system functions fairly. Is based on VB6.0+ ArcEngine9.2 development, the skin interface, using a relatively large data inside Activebar3.0, inconvenience upload, need to be to my request.
