Dioptra provided the City of Pocatello with professional services for the GPS data collection of the city sewer system. This included the establishment of GPS processes and procedures for city staff, training of city staff on the proper use of GPS equipment and software, and assisting with in-field data collection processes. This GPS data was checked by Dioptra to ensure data integrity prior to the implementation of the data into the city GIS system. Although this was a GIS project, Dioptra implemented the use of RTK GPS for GIS purposes. This included the establishment of new data collection routines that allowed attribute information to be assigned to each GPS position. These attributes provide all the key information about the utility features such as depth, size, condition, materials, etc.
