The education in Remote Sensing methods (RS) become important because of widely application in Remote Sensing and Photogrammetry communities using for the terrain mapping purposes, for spatial data modeling, solving engineering tasks, measuring of architectural heritage, presenting data for GIS, etc. The number of potential users of the Remote Sensing methods tends to increase, because of high degree automation in imagery processing and high resolution imagery received from satellites. The Remote Sensing technologies and modern digital photogrammetric workflow are nearly fully in contiguity.
The objectives of analysis and investigations are: to outline education trends in RS, to search the possibilities for effective training in the understanding of RS methods and getting comprehensive knowledge in application, to find out the best solution in education with high efficient of feedback.
The methodology is based on developing the fundamentals for the education in Remote Sensing methods, considering studying committee requirements. The study module (the guide) with selected appropriate subjects is presented. The subjects such as satellite imagery processing techniques creating mapping product, 3D surface modelling, etc. are defined. The evaluation methods of knowledge (achievements) are outlined.
Different methods and softcopies are proposed and demonstrated for the training of imagery analysis and processing. The integration of functionality of different Digital Remote Sensing and Digital Image Processing Software (educational – UNESCO Bilko, LISA, Digital image processing Simulator and professional – ERDAS IMAGINE, Photogrammetry Suite; Pix4Dmapper) is analyzed as well with intention of extending the application areas and possibilities for better understanding of modern technologies reducing time cost for assimilation of RS methods.
The conclusions and recommendations include the usefulness of a usage of different softcopies in training process. The employment of software developed for education purposes, for example as is BILKO and LISA, is highly recommended. Advantage of such system is that software not requires powerful computers and furthermore all processes are clearly visible. Imagery processing software gives final results, but impossible to analyze under the watchful scrutiny, the usage of software DIPS helps to fill some teaching gaps. However, complete professional imagery processing systems as is softcopy ERDAS IMAGINE LPS simplifies and modernizes production workflow, gives possibilities to study the particular image processing steps as well. The virtual learning for imagery restitution using developed material at Internet environment (e.g., Moodle) is recommended, presenting material at various configurations, on video mode, etc. The training in fundamental definitions of digital image processing for practical purposes it is recommended to use interactive/Web system LDIPInter.
