• Review your answers to question 2 and 5 to answer the following: for the general audience, describe how to fix misaligned and improperly referenced spatial data, including taking into consideration project properties.

Answer: We should consider if the data’s projection system is in accord with the map’s projection system or if the data or map has a projected system at all. If the projection systems are not the same, we should adjust them to the same system; if the map or the data has no projected system but a coordinate system, we should use a projected system to align the map and data.

• Review your answer to question 10 and discuss the advantages to using remotely sensed Landsat data for geographic analysis.

Advantages:

– Remotely sensed Landsat data can reveal the whole picture of the selected study area.

– It can also document the changing of the landscape for future compare and contrast.

– Landsat data can be documented as raster images, which can be manipulated in ArcGIS to add more information (height, vegetation, slope, etc.) on.
