How is Geographic Data Created?
Geographic data can be captured and created using various collection methods (digitization, GPS, aerial photography, etc.) and software systems (ESRI, Quantum GIS, etc.), and stored in various formats (vector, rasters, tables, etc.).
The Town currently uses ESRI’s ArcGIS 10.2 Suite and Carlson’s Survey 2017 software systems for generating and manipulating geographic data and creating cartographic products.
For field data collection, the Town uses a TopCon GRS-1 GPS receiver and PG-A1 external antenna that provides 3-cm accuracy.
