Recurring Orthophotography & Obliques
NCTCOG is partnering with Nearmap to provide recurring orthophotography and/or oblique imagery "as a service" to public agencies in North Texas through the Spatial Data Cooperative Program (SDCP).
Nearmap is unique in its approach to aerial imagery collection, as data is collected for their service area 2-3 times a year and then provided via subscription-based pricing vs the traditonal NCTCOG coordinated orthophotography which is collected annually based upon the needs of the participants. The Nearmap approach provides more frequently updated imagery, faster delivery times and can reduce the cost of acquisition for comparable products.
NCTCOG is offering two Nearmap subscription options through the SDCP: Orthophotography and Orthophotography + Oblique Imagery. These options are only available to public entities in the NCTCOG 16-County Region. For information on cost and deliverables click here. All listed costs are annual.
NCTCOG is not replacing its traditional orthophotography with the Nearmap imagery. Both products will be offered through the SDCP. Nearmap's ortho is 3-band and due to the faster turnaround time there can be some loss in vertical accuracy. How an entity uses the imagery will determine which type of orthophotography fits their needs. For many, there may be a need for both. The table below shows an internal comparison of NCTCOG's traditional orthophotography and Nearmap's recurring orthophotography.
If you are public agency in North Texas and are interested in purchasing a Nearmap subscription send us an email or look for the Nearmap product on the next SDCP Order Form.
Orthophotography, LiDAR and derivative products from past projects may be viewed and printed from DFWMaps and purchased in digital format after a project completes through the DFWMaps Marketplace. For more information on orthophotography, visit the SDCP FAQ page or send us an email.
