The Geographic Information Systems, or GIS, division is responsible for providing all geographic data analysis and mapping for the Town. The GIS coordinator is charged with finding ways for Town staff to use GIS to complete their work more efficiently and effectively.

What is GIS?
(taken from esri.com)

A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.

GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts.

A GIS helps you answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared.

GIS technology can be integrated into any enterprise information system framework.

What Can GIS Do?

Map Locations
Mapping where things are lets you find places that have the features you're looking for, and to see where to take action.

  1. Find a feature—People use maps to see where or what an individual feature is.
  2. Finding patterns—Looking at the distribution of features on the map instead of just an individual feature, you can see patterns emerge.

Map Quantities
People map quantities, like where the most and least are, to find places that meet their criteria and take action, or to see the relationships between places. This gives an additional level of information beyond simply mapping the locations of features.

For example, a catalog company selling children's clothes would want to find ZIP Codes not only around their store, but those ZIP Codes with many young families with relatively high income. Or, public health officials might not only want to map physicians, but also map the numbers of physicians per 1,000 people in each census tract to see which areas are adequately served, and which are not.

Map Densities
While you can see concentrations by simply mapping the locations of features, in areas with many features it may be difficult to see which areas have a higher concentration than others. A density map lets you measure the number of features using a uniform areal unit, such as acres or square miles, so you can clearly see the distribution.

Mapping density is especially useful when mapping areas, such as census tracts or counties, which vary greatly in size. On maps showing the number of people per census tract, the larger tracts might have more people than smaller ones. But some smaller tracts might have more people per square mile—a higher density.

Map Specific Areas
Use GIS to monitor what's happening and to take specific action by mapping what's inside a specific area. For example, a district attorney would monitor drug-related arrests to find out if an arrest is within 1,000 feet of a school—if so, stiffer penalties apply. Or, find out what's occurring within a set distance of a feature by mapping what's nearby.

Map Change
Map the change in an area to anticipate future conditions, decide on a course of action, or to evaluate the results of an action or policy.

  1. By mapping where and how things move over a period of time, you can gain insight into how they behave. For example, a meteorologist might study the paths of hurricanes to predict where and when they might occur in the future.
  2. Map change to anticipate future needs. For example, a police chief might study how crime patterns change from month to month to help decide where officers should be assigned.
  3. Map conditions before and after an action or event to see the impact. A retail analyst might map the change in store sales before and after a regional ad campaign to see where the ads were most effective.

How is GIS used?

GIS is used at the Town of Penfield to: 

  • Map many aspects of the Town, including location of environmental features, infrastructure, open space, and school district boundaries
  • Help staff analyze applications for proposed development
  • Create “Official Town Maps” of streets, points of interest and zoning
  • Notify residents of upcoming meetings
  • Produce trail maps for hikers to use while exploring Town parks
  • Prepare for major Town events, such as the 4th of July
