The Basics What does GIS stand for? Geographic Information System Yeah, but what does that mean? GIS is a computer system designed for capturing,
storing, integrating, analyzing and displaying data
from a geographic perspective GIS Geography Data - Attributes Maps Analysis Web Location,Location,Location The data behind the location, this is the power of a GIS! Tried and True - Maps Meets the 21st Century Location + Data = Analysis Crimes around a location Planning See Statistical and Spatial Trends The Web - To the Mobile Web Roughly 85% of municipal government
services are location or address based System that includes software, hardware, data, and personnel
Use of the relative location of features in x, y, and z space to establish relationships between features
Technology that is used to analyze features that make up the physical world Elements of a GIS Concept of Layers GIS organizes geographic data into a series of layers and tables.
Data is referenced to geography, with real-world locations that could overlay one another.
GIS links the location of each layer to give a better understanding of how the features interrelate. Types of Layers Points : Fire Hydrants, Man Holes, Meters
Lines: Mains, Laterals, Streets, Creeks
Polygons: Pressure Zones, Detention Ponds
Annotation: Text Labels
Raster: Aerial Imagery, Elevation Surface Where you are Now CAD maps
Access / WinCan records
Maintenance / Inventory
Work Orders Attributes are the descriptive tabular data associated to the map features
Databases are the foundation of the GIS and store the data for each feature Data = Attributes Service Request
