2.  The textbook GIS methods section: Provides basic understanding of GIS concepts What is RS? How can we use RS for GIS, when, where and why?

3. Remote sensing is the art, science, and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring and interpreting imagery and digital representation of energy patterns derived from non-contact sensor systems ( American Society for Photogrammetric and RS ). American Society for Photogrammetric and RS

4. 1) Collect information about the earth surfaces. 2) It provides a reliable and cost-effective means of studying the natural and human environment. 3) Can be used for protection, natural resources management and planning.

5.  Development of urban planning applications using RS.  Monitoring Urban Growth.  Mapping cities and communities.  Planning and Policy: To study land use, urban zoning. To detect changes in land use from agricultural land to a construction site or housing development.

6.  RS support multi-scale urban planning.  Three scales of urban and rural planning, such as: city and town system planning. urban master planning. detailed urban planning.

7.  Examples: Categorizing natural disaster damage assessment using satellite-based. Comparison of remote sensing image processing techniques to identify tornado damage areas from Landsat TM data.

8. o When can we use RS for urban planning? o When we can not use RS for urban planning? o Chapter 3 discussed RS for GIS applications, what are those?
