Geographic Information Systems (GIS) is a tool for linking and displaying graphical (spatial) data with tabular data. This combination allows for the creation of products and services that would be difficult, if not impossible to produce by other means. GIS allows for the management and analysis of large sets of information. GIS is increasingly important to support decision-making. The development and use of a GIS can be complex and expensive. To effectively overcome these, an organization must be committed to its GIS for the life of the system.
Land Data Maintenance
It is a primary role of the GIS staff to maintain land data in a GIS format that accurately represents the City's land base. In general, geographic features are located on the earth surface. These can occur naturally (rivers, vegetation), can be constructed (roads, buildings) or can be a subdivision of land (cities, parcels). GIS models the world with points, lines and polygons to represent these features. A GIS can also maintain attribute data (information associated or linked to the land data) about these features. A primary goal and purpose of a GIS is to maintain current and accurate information. To accomplish data maintenance with accuracy and a high level of integrity, there must be close coordination with the source of data (in this case the City's land development departments).
