Geographic Information System (GIS) Mapping
Introduction to Dublin GIS
A geographic information system (GIS) is a computer-based tool for mapping and analyzing things which have location. It collects various types of information and arranges it in such a manner that makes it easy to find what you're looking for. GIS technology stores this spatial data in a variety of "layers" that, when linked with databases, provide a complete overview of the overall infrastructure. Information stored in our GIS database can be viewed together, as many different layers as needed, depending on user requirements. These abilities distinguish GIS from other information systems and make it valuable to a wide range of public and private enterprises for explaining events, predicting outcomes, and planning strategies.
What will GIS do for me?
The easy-to-use application will be distributed over the internet using a web browser, which will allow you to interact with maps quickly. Searches can be performed to locate parcels, street intersections, subdivisions, and more. You will be able to zoom and pan around the map, create buffers, print your own maps to scale, and measure distances with ease. The GIS will also be tied to many databases which will allow you to create reports on selected objects.
What data will the GIS provide?
Flexibility is also incorporated into the GIS, allowing us to continually update and modify the data as more development and changes occur in the City. Creating, editing, and maintaining the GIS data remains to be the most crucial part in having a successful GIS, therefore is the main focus of the GIS Staff.Our GIS includes the following types of data:
Land Based data: This data captures elements available from aerial photographs, including building outlines, roads and streets, driveways and parking lots, manholes, elevation contour lines, and other ground-oriented features.
Parcel data: This element indicates property ownership as recorded by the City of Dublin's HTE Land File and the County's Auditor's office.
Utility Infrastructure data: This data includes the City's water distribution system, sanitary sewer network, and the storm sewer network. This data is captured by the Engineering Division.
Raster data: This is the aerial photography or orthoimagery captured via plane and soon-to-be captured via satellites in the spring of this year.
