Upon doing this project, there are some issues that arose that may have skewed that data, making any analyses less accurate. Some assumptions were made, also making any data input less than accurate. The first such inaccuracy would be the production of the image GVRDSLOPE, using the slope operation. I was asked to enter a conversion factor since the units on GVRD_DEM did not match together. This conversion was an estimation, and it was unlikely to be totally accurate. This inaccuracy has a lot of implications since that image would help produce GVRDBESTSLOPE which in turn, was part of making RESLOPE, etc. Overall, the inaccuracy of that image would have an affect on the the final images. (show another possible slope with an alternate conversion)

With the overall analysis of the images to produce BESTOVERALL and BESTOVERALL2, the original images, within IDRISI, showed 5 and two points respectively. However, these points did not show up when converting the images to a JPEG file. This is probably due to the fact the points were too small. However, as the final images suggest, more points are shown when a portion of BESTOVERALL and BESTOVERALL2 was zoomed in. While not all potential plots of land in the Lower Mainland are shown (Maple Ridge and Coquitlam), these areas were not chosen due to their distance from the city and so viewing them was not all that important.

Another aspect of the analyses has to do with the type of soil in which I decided to build on. I chose granite and shale/sandstone/volcanic soil types because of there rigidity and their ability to not absorb water. As mentioned earlier, it would likely be more costly to build on these types simply because they are tougher to build on. However, The would be less susceptible to underground water movement or land slippage due to an earthquake or heavy rainfall. However, cracks can form within the granite and if water happens to seem in and freeze, it is possible to unstabilize the base. Similar effects could also occur for the other soil type. Yet, it could also be feasible to build on different soil. The two types of soil that were chosen were what I thought were best for my project and fit the criteria that I needed.

With regards to the slope, the degrees of the slopes (15 and 7.5) are estimations on how the ideal slope for developing residential  housing. It is quite possible to to build and get better protection on slopes that are steeper. Conversely, it is possible for a slope to fail if it is less steep. In terms of land use, it is possible to rezone and receive a permit on land that is not allocated for residential development. This includes commercial, industrial, and even open land land use. It should also be noted that just because a portion of land is lower than 25 metres in elevation, it does not mean that it is necessarily susceptible to flooding. If an area of land is near a river and is on low lying land, it is at risk for flooding. However, there may be high-rise apartments near a river, situated at an elevation that is less than 25 metres and even during a flood, most floors would probably not be inundated with water. It is also possible that low lying areas are protected from potential flood waters from some sort of barrier such as a dike.
