• Data collection: for my project, I need lots of human factors data, which I could find some from the mdb table but still I have to given up some important indicator such as medical services, drug/alochol abuse etc.

• When preparing data, it is very hard to find the relationship between the census field to the image because all the mdb tables do not have field names and it takes a long time to figure out the matching process.

• Few of the maps are coming from the reclass of land use, so I assumed that the "institutional" in the landaus means the schools and "park" as recreational land.  It might also have some error within the assumsion

• The given data does not included a detail  GVRD public transit route.  Only Vancouver and Burnaby bus rout are provided, which is not enough for my analysis, so I use the main roads map and assume that most of the main roads have bus rout run through.

• I use the boolean for all my analysis map which is very restricted, it might miss some second best factors.

• When doing the analysis, there are always some unexpected area show up as the best criteria, such as the "West Wood Plateau" is one of the high low income area which might cause  a misleading decision.

• The last and worse problem I have encountered is I crash my computer during the last weekend and I lost most all of my html and images files which I have re-do the web page in two days.
