%X The visualization of scientific computation is spatial data field visualization. Scalar, vector and tensor quantity are principal parameters to define multi_dimensional data field in linear electromagnetic system. Based on cause and effect rule of instantaneous change electromagnetic system. The response of remote sensing sensor to the electromagnetic field can be regarded as the reflectance of ground electromagnetic field. The pixel is the digital media to record the reflectance. Because the linear connection between ground electromagnetic field and multi_band DNS, the digital image can be expressed as multi_dimensional spatial data field. In multi_dimensional linear vector space, values of data field can be calculated, differentiated, analyzed and the angle function also can be formulated in the space. The mapping of useful weak feature in remote sensing data field is also carried out based on angle analysis.
