| Conversion Specifications | Original scanned tiffs approximately 148mb per map were converted to smaller web sized images (2-3mb) using Photoshop to allow for easy access while preserving image quality. Each map was georeferenced using ArcGIS 10, aligning each image to its appropriate geospatial location according to reference layers consisting of satellite imagery, street centerlines and parcel data. Georeferencing protocols were established to maintain consistently projected images using a NAD 83 State Plane Utah Central FIPS 4302 projected coordinate system. While care has been taken to maintain georeferencing accuracy, some map features have changes over time, resulting in each map being georeferenced as closely to its appropriate location as possible. |
