DDTI - Basemapping Processes

Our Process

Point-based addressing makes possible the accurate location of more than 95% of otherwise unverifiable accident sites, translating into incremental roadway safety funding opportunities for your county government.

Data Collection

Experience has proven our process to be the most thorough, accurate and reliable data compilation method available. Our highly qualified GIS professionals conduct Field Verification and Point-Based Mapping, which includes:

All address locations
All roads
Visible road assets
All related emergency and transportation features

Data Processing

Upon completion of the field collection, the data processing phase begins. We conduct extensive discrepancy reporting of the field-verified data, comparing it against existing databases. Finally, before delivering your data set, we simulate calls to 9-1-1 from every address point we recorded to ensure the quality of your data and the safety of your community.

Despite the intricate detail work involved, our teams complete the field collection and data processing work for a full turnover of your county’s data in three months or less*. This includes all municipalities, private developments and other border areas.

* Typical production schedule. Delivery will vary based on scope of services.

Data Maintenance

Maintenance is the key to upholding the quality and accuracy of your evolving data set, in preserving the integrity of the data, and allowing it to evolve with your ever-growing communities. We know from experience that your road and address network change every day, with new homes being built or roadways installed.

Because these data sets are so comprehensive and meet the needs of all government offices, multiple agencies access this information on a regular basis. Many have found their own methods of copying, changing and storing variations of data in multiple places.

With real-world practices in mind, we developed a single source solution for maintaining your data. We store your information on web-accessible servers, ensuring that all users access the same data, at the same place, in the same way. Our Data Maintenance Software allows government employees to easily and efficiently create, modify, and distribute road and address data across departmental lines so the mapping system maintains its relevance and accuracy well into the future.

Basemapping Testimonial

DDTI’s strong GIS reputation was a major factor in selecting them after our competitive bidding process. Having developed their own GIS software and with its vast use around the world, DDTI offered the most robust and cost effective solution for our needs. But with five PSAPs in our jurisdiction, the one feature that was most compelling is the ability to remotely update all our data on a daily basis utilizing their web-based solutions.
