Better Monitoring of Pavement Conditions
The City of Durham is responsible for maintaining a majority of their own road work, maintenance, and repaving. As a result, the city pays for a road-condition survey which samples different sites, evaluating the level of degradation. With Nearmap imagery, surveyors are better able to identify specific locations with imagery captured multiple times a year.
Time Savings and Documentation of Road Repairs
Like any city, the patching of potholes is a constant, ongoing project. With imagery from Nearmap, however, the City of Durham has been able to eliminate several steps in the process. Now the city uses an application integrated with Nearmap imagery where contractors can view the areas on their phone or tablet out in the field. The surveyors can edit and draw the areas that need patching instead of physically going out and spray painting them.
More Detailed Maps of City Riparian Zones
Previously, with only leaf-off imagery, surveys of riparian areas in Durham proved limiting. With imagery captured during both leaf-off and leaf-on seasons, riparian buffers around streams can now be monitored for growth and expansion. The buffers can be alerted if there are issues with a stream’s path, whether sediment is clogging up one part of the area, or if there is repeated flooding or people intruding on a buffer.
Accurate and Detailed Customer Billing
Serving some 78,000 customers throughout Durham, the public works office has found the high resolution imagery has improved their billing processes by producing web service maps that capture individual storylines.
