In this paper,the geographic position rectification,classification and mapping of LANDSAT MSS image are studied and discussed on the basis of the research of the supervised classifications in Hangzhou region and Darning mountain in Fuchunjiang country.The method of "one category with several groups (or clusters)" and the rule of the relative distance threshold in the supervised classifications are proposed,designed and used in order to improve the quality of the classifications.The factors of the distortions in MSS images are analyzed,and the continuous and discontinuous distortions in the images are rectified in order to meet the high accuracy requirements for mapping.The methods of the directed mapping and the resampled mapping are tested and studied.The characteristics and efficiency of the plotter are specially considered to improve the map precision and increase the plotting speed.The plotting program is designed to plot various classification maps with different scale and is easy to use.On the other hand,the classification maps are rectified and mapped on a Gauss-Kruger grid for the interpretation and application.In the paper the map of classification with color in the West Lake region in Hangzhou is given in scale 1:50,000.The studies mentioned above provide not only the ideal maps for the interpretation of the images and mapping of the thematic maps,but also a good basis for the integrative processing of the multi-date,multi-sensor remotely sensed data and the non-remotely sensed information,and for the renewing of the data in the database of the remotely sensed images.

In order to solve the problem of slow speed,based on the canonical algorithm of calculation of the correlation integrals,this paper not only provides several improvements,but also puts forward two optimized algorithms.The algorithms are based on the region of embedded dimension and region of distance threshold.They are filled in table of [ m max × r max ]( m max is number of embedded dimension, r max is number of distance threshold) by batch methods giving up the one by one processing methods.In this paper,the theory and algorithm are narrated in detail.The performance of two optimal algorithms is compared with canonical algorithm and improvement method.The experimental result shows that optimal algorithms need least time to calculate the correlation dimension for same length time series with same number of distance threshold and embedded dimension since they have little redundant calculations and enhance the calculation efficiency obviously.
