It has also helped open up communications between different agencies. With this capability GIS has been able to expand into new areas of use. Some examples of how GIS are used include emergency dispatch which displays the callers exact location to the dispatch. CDCs can use GIS to map their neighborhoods in order to get funding for low-cost housing. Individuals can determine if they are being fairly taxed to others in their neighborhood with similar size houses and lot size.
Police officers can track the movement of crime, drugs, gangs, and activity month by month.
GIS can be used by several different city agencies. Since there are so many agencies that may be using GIS, the cooperation among agencies has increased. This cooperation has occurred because of the collective responsibility in maintaining the GIS information across a city, county, state, or nation. Another reason this has occurred because now the agencies can actually see how dependent they are on information that may be collected by another agency and also by being dependent on another agency for this information it saves them time. Thus, because there is a direct benefit in using GIS for the workers, it is in everyone's best interest to keep the system going and updated.
