Research and Apply on Key Technology of the Spatial Analysis based on ArcEngine

The vector data obtained by the Satellite analysis usually have no position information. This paper mainly analyzes the spatial vector data to determine its position information, monitoring the planting area of the crops (wheat, corn) and the facilities area. Moreover, we introduces determine of relationship between point and polygon and the relationship between the polygon and polygon in spatial analysis.The attribute connection of the central point method and the preponderant area method both are achieved. According to the research, the result shown that the central point method is suited to the continuous and large-polygon geographic feature, Such as wheat and corn and other large-scale cultivation crops, while the preponderant area method is suitable for the sub-classification and small-polygon geographic feature.
