Error

The first problem I met in TerrSet is buffer, I cannot use buffer for my community center 1 data before re-class done in Macro Modeler and it would showed the red background image, so I had to re-class it, combined data to new datasets. The correct image would like this: No data area showed dark color and the number is 0, data area showed red color and the number is 1 (The samples were shown at methodology page). The error is below:

The second problem I met is that overlaying the public garden area with land-use data. I can overlay the community center and commercial part of land-use. However, if the entire land-use data were overlaied it would be failed, or the overlay output was displayed separated data, which means the community center buffer were not able to cover the correct location on land-use image (Cannot get the overlay of commercial part and community center). For solving this problem I used zoning_distinct data and transported it from ArcMap to TerrSet in SHAPEIDR tool. Then, the land-use vector data was confirmed and adding it to Composer. Finally, if it was colorful or black, just changed the color to white. (The sample was shown at Result page).

What is the useful of this final map

This map showed directly the possible suitable areas of public garden. It is also express where is the high population density at commercial zone in Vancouver, because the purpose of this map is that looking for the best areas for building public gardens with minimum cost and high population.
