Aerial vehicles allow surveyors to collect data needed in a fraction of the time taken by traditional methods by fitting them with GPS technology, high-resolution cameras and a host of other sensors to offer an innovative approach to land surveying, mapping, 3D site modeling and more.
In the realm of aerial surveying, 1519 offers a wide range of technology and project-specific solutions. Depending on which aircraft type is best suited for your project, 1519 has licensed and trained pilots for both unmanned and manned aircraft. When it comes to precision and technology, we are a cut above the rest. Our fleet of aerial vehicles is outfitted with a broad range of sensors, allowing us to capture and format the data you need to get the job done right.
Notable Aerial Services Projects
Sycamore Creek Sanitary Sewer Relief Interceptor
Aerial Public Works
The proposed alignment for this project traversed through a city park, crossed US Highway 287, Sycamore Creek, and public right-of-way. This project was completed in two (2) phases.
The first phase involved providing aerial imagery and topographic survey for a route study. 1519 established control points and benchmarks throughout the project limits. Horizontal coordinates were established using GPS and vertical values were established by conventional leveling. All control was tied into the City of Fort Worth control network. 1519 utilized drone technology to collect the aerial imagery and topographic data along six (6) proposed alignments. 1519 also performed boundary surveying in specific areas to locate public rights-of-way for the final alignment. 1519 researched public records to obtain the deeds of current property owners, plats, and existing easements within the project limits. Property corners were recovered, boundary lines were resolved by a Registered Professional Land Surveyor, and a digital property map was created.
The second phase involved surveying the location of the final alignment. For this phase, 1519 extracted topographic data collected by the drone within fifty (50) feet on each side of the proposed alignment. 1519 performed on-the-ground surveying to provide supplemental data in obscured areas such as creeks and high vegetation areas. 1519 also finalized the boundary lines and property map for the remaining properties that were not established during the route study phase.
1519’s use of drone technology enabled the client to receive data quicker and more cost-effective than conventional survey methods, which helped meet an aggressive schedule.
Coca-Cola Plant Expansion
Aerial Development Engineering Surveying
1519 provided work for the Coca-Cola bottling plant located on the corner of Imperial and Hewitt Drive. Our Surveyors and Engineers provided services for a parking lot, building expansion, detention ponds, and future development at the plant. One of the key unique challenges to this project was the fact that this was an operating plant with a high amount of truck traffic in our project area. As such, it was next to impossible to conduct the needed survey work with traditional methods and maintain a safe working environment. We used one of our UAVs to collect the required topographic data and other site features needed for Civil Design.

Parker County Transportation Bond Program
Aerial Public Works Surveying
1519 set aerial panels throughout the project area and managed the aerial flight of the project. The coordinates of the aerial panels were established using GPS and scaled to Texas Department of Transportation surface coordinates. The aerial flight included the planimetrics (2D features), a digital terrain model of the project, and orthophotos. 1519 performed the QA/QC of all data prior to submittal to the client.
1519 also performed the boundary survey of approximately four (4) miles of the proposed route and obtained copies of subdivision plats and ownership deeds within the project limits. Boundary monuments were recovered and a property map was created. Included in the boundary survey were fifty (50) documents with legal descriptions for right-of-way acquisitions, signed and sealed by a Registered Professional Land Surveyor.
After documents were completed, 1519 set monuments delineating the proposed right-of-way. 1519 also staked the proposed right-of-way so that property owners and appraisers could see the new route and construct new fences.
1519 Surveying, LLC worked with engineers, land men, title agents, property owners, and other land surveyors in order to complete the project. Property owners were always notified of 1519’s presence prior to accessing their land.
1519 also performed the survey of the Level “A” and Level “B” utilities that were marked by a private subsurface utility engineering firm. This included surveying the locations of the marked utility lines, test holes, and locations of all surface utilities within the project limits. 1519 was able to meet all project timelines and deliverables while staying within budget constraints.
Farm to Market Road 428 and County Road 55/West Glendenning Parkway
Aerial Public Works Surveying
1519 Surveying, LLC (1519) completed the schematic design survey for approximately two (2) miles of FM 428 and County Road 55/Glendenning Parkway, from 1,000 feet west of Dallas Parkway to 1,000 feet east of SH 289 (Preston Road), for the Texas Department of Transportation (TxDOT). 1519 established four (4) permanent horizontal and vertical control monuments and set secondary control points along the proposed route. 1519 ﬁeld crews recovered property corners and right-of-monuments and 1519 oﬃce personnel completed the right-of-way veriﬁcation map for the proposed route. Field crews also surveyed the locations of drainage structures, utilities, signs, and creeks within the existing right-of-way. 1519 completed the aerial mapping of the proposed route, which included seven hundred (700) feet on each side of the proposed alignment. The planimetric (2D) features were extracted by processing the imagery from a ﬁxed wing ﬂight and the .tin (3D) data was created by using the point cloud data from a helicopter LiDAR ﬂight. Deliverables included signed and sealed control sheets, imagery and point cloud ﬁles, and Microstation ﬁles completed to TxDOT standards.
Waco Suspension Bridge Aerial Design Survey
Aerial Public Works Surveying
The Waco Suspension Bridge is a historical landmark located in downtown Waco, Texas that was built in 1870 by Thomas Griffith, a New York civil engineer. He commissioned the bridgework and cables for the project to be supplied by The Roebling Company, the same firm that later helped build the famous Brooklyn Bridge. After completion, The Waco Suspension Bridge quickly provided a crossing over the Brazos River for the Chisholm Trail and other north-south travel through Texas. Due to high traffic, the town doubled in size over the next decade which contributed greatly to The City of Waco’s development. Recently, 1519 Surveying, LLC (1519) was engaged by the Engineering firm hired by the City of Waco to refurbish this 150-year-old bridge to its past glory.
1519 had to produce an Engineering Design Survey on this piece of Waco history, which required the integration of UAV Mapping/Photogrammetry and field surveying to produce point cloud files and orthoimagery within the project limits. The point cloud and orthophotos were used to provide accurate measurements of specific bridge features such as hanger and floor beam lengths for refurbishment purposes. Data was acquired using drone photogrammetry with over 1000 photos taken from various angles and flight paths over and around the bridge. Photogrammetry software was then used to generate the 360-degree point cloud and orthophotos. Drone data was then merged with field surveying shots and terrestrial scanning point cloud files in a CAD environment to deliver the requested measurements and values from the client.
Deliverables included a digital design survey drawing in AutoCAD (.dwg) showing visible surface features and requested measurements located, an ASCII point file, a copy of field notes and field sketches, point cloud files in LAS format, and digital aerial orthophotography of the entire bridge structure.
