1. Use geopandas to create data point. I succeed to use this tool to find the location of each 311 spot within the CT shape file, however, failed to apply the same method to locate the mental health care center in the same CT shape file. The reason why I choose to use this method is because it’s good for special analysis especially when people want to figure out whether or not a target point (geometry) is contained in a specific region. The ideal situation is when both the geometry and polygon (specific region) are already given and valid. In case if any value is missing, we still can create the geometry according to the exact coordinate system requirement, as long as longitude and latitude are available or provided.
