GIS Data

Collection & Creation

Broome County GIS is continuously collecting or creating new GIS data.
GIS data can be collected and created using a variety of methods:
  GPS (Global Position System) Units are used to collect field data. Examples include culverts, signs, and outfalls.
  Heads-up digitizing uses existing GIS data and imagery in the desktop enviroment to create new data. Examples include bus stops, zoning districts, and empire zones.
  Geocoding is a method of converting address-based tablular data into GIS format. Geocoding uses an address locator to match addresses to a reference layer. Most commonly this layer is a street centerlines with address ranges. However, other layers such as 911 addresses or tax parcels can also be used.

Keeping GIS data up to date is of primary importance to all users who rely on it.
Base Map layer maintenance is the priority. This data includes tax parcel boundaries, street centerlines with address ranges, and in the near future, 911 addresses.
Planimetrics can also be included in the Base Map category however at this time the planimetrics are not maintained and are based on 1989 data.
The maintenance function accounts for roughly 50% of Broome GIS staff time and will only increase as new layers are created.
GIS data not maintained by Broome County may or may not be updated on a continous basis.

Although the 'mapping' or visual component of GIS is important, the data can be used for more than just this.
Simple and complex queries can be run based not only on attributes of particular layers, but also based on spatial relationships.
