Lecturing on satellite imagery processing and GIS based on internet and open source software

In field of Remote Sensing and GIS, recently become easier to find and download satellite imagery from official data provider website freely, but the aggravating circumstance is the expensive price for satellite imagery processing and GIS commercial software. This paper attempt to give solutions for this matter. At present we have many choices because of the presence of open source software and online software tools. We can easily download from internet and use the software. We are using general method in giving lecture on satellite imagery processing and GIS based on internet connection availability and open source software. The case is urban growth monitoring with road network as a driving force from developing of transportation access. To obtain the optimum way in giving lecture on satellite imagery processing and GIS. We applied statistical analysis using six variables (optimum duration, subject matter, illustration and descriptions, feedback, planning the lesson and material, repeating the lesson from quiz) in three different duration time (45,60, and 90 minutes). We found the most optimum duration time in giving lecture using internet connection and open source software is 90 minutes with only single subject matter. This method is the most simply method and freely to give lecture in satellite imagery processing and GIS.
