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.
Analysis & Modeling
- 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.
