| Abstract: | Digital and attribute database of elevation anomaly isoline map with ArcGIS is realized,and elevation anomaly database is established.Based on contrast and analysis of three mathematical methods of distance weighted,least squares interpolation,gradient interpolation in object-oriented Visual Basic 6.0 application environment,using MapObjects geographic information controls,the related function of elevation anomaly,including automatic query and display,zoom and roam is realized. |
