The Orthomosaic Process
After offloading all the files from the job site, I start my workflow process by creating the orthomosaic. I typically use two software programs for this – MetaShape and WebODM. MetaShape allows me to check the images and ensure everything is in order, while WebODM is my go-to for presentation purposes.
For this particular project, I decided to make a Solstice orthomosaic from the photos I took on September 3rd. I imported a total of 409 images, which included both the north-south and east-west passes. In the previous part, I explained the importance of taking these different angles to capture a comprehensive view.
The Final Model
Once all the photos were aligned, I proceeded to build the mesh, add textures, and create the point cloud, digital elevation model, and orthomosaic. The orthomosaic is especially interesting to our clients, as it provides a detailed and accurate representation of the area captured by the drone.
As you can see from the final model, the orthomosaic turned out well. It showcases the site from a bird’s eye view, allowing you to see the various structures, land contours, and other important details. This kind of visual representation is incredibly useful for planning, analysis, and documentation purposes.
Benefits of Orthomosaic
Orthomosaic mapping serves various purposes and offers several benefits to different industries. Here are a few key advantages:
Accurate Measurements: By using advanced algorithms and image processing techniques, orthomosaic maps provide highly accurate measurements. This is particularly beneficial for construction companies, land surveyors, and architects.
Effective Communication: Orthomosaic images and videos allow for clear and concise communication between project stakeholders. By providing a comprehensive view of the site, everyone involved can understand the project’s progress and make informed decisions.
Time and Cost Savings: Orthomosaic maps eliminate the need for traditional surveying methods, which can be time-consuming and costly. Drones equipped with high-resolution cameras can capture the necessary data in a fraction of the time, reducing overall project expenses.
Improved Safety: By using drones to capture data, workers can avoid potentially hazardous situations. Drones can reach elevated or inaccessible areas without putting individuals at risk, making them an invaluable tool for site inspection and monitoring.
Note: If you haven’t watched part one of this series, I recommend doing so before continuing with part two. It will provide you with important background information on the videos and images we imported for this project.
Go ahead and close out a web odm as well. So once we have our geotiff exported, we can then bring it into another software called QGIS, which is a geographic information system. Now QGIS allows us to overlay different layers of information onto our geotiff, such as property boundaries, roads, and other relevant data. This helps us in analyzing the orthomosaic and understanding the construction progression of the drone project.
Analyzing the Orthomosaic
In QGIS, we can zoom in and out of the orthomosaic to get a closer look at specific areas. This is particularly useful when we want to examine the construction progress of individual homes. By zooming in, we can see the exterior walls, roofs, and other details of each house. This allows us to track the progress of construction over time and identify any changes or improvements that have been made.
Additionally, QGIS allows us to measure distances and areas within the orthomosaic. This is helpful in determining the size of each house or the total area covered by the entire community. With these measurements, we can compare different stages of construction and quantify the progress that has been made.
Comparing Before and After Orthomosaic Models
One of the key features of our drone construction progression job is the ability to compare before and after orthomosaic models. This allows our clients to see the changes that have occurred in the construction site over time. By overlaying the orthomosaic models from different dates, we can clearly visualize the progress and identify any modifications that have been made.
For example, if a client wants to see the changes in a particular area from July 23rd to August 20th, we can easily generate a side-by-side comparison. This helps them to assess the efficiency and effectiveness of the construction process and make any necessary adjustments or improvements.
Expanding Flight Path for Better Coverage
In order to capture a more comprehensive view of the construction site, we recently expanded our flight path. By adjusting the flight path, we were able to capture additional images and ensure that no areas were missed. This helps us to create more detailed orthomosaic models and provide our clients with a better understanding of the construction progression.
While our drone construction progression job has been successful so far, we are constantly looking for ways to improve and enhance our services. One area we are currently exploring is the use of artificial intelligence (AI) in analyzing the orthomosaic models. By using AI algorithms, we hope to automate the process of identifying changes and improvements in the construction site, saving time and effort for our clients.
Setting up Overlays for Before and After Comparison
In order to create before and after comparisons using orthomosaic images, it is necessary to set up overlays. Many people have asked how to align these images, so let’s take a closer look at the process. For today’s demonstration, I have already prepared the August 20th and September 3rd orthomosaic files, which are full-size Geo TIFFs. It’s important to note that these files are very large, with the August 20th file being 1.4 gigabytes and the September 3rd file being 1.55 gigabytes. Due to their size, we do not embed these Geo TIFFs on our website but can provide them to customers via Dropbox or other means.
Exporting Models for Sketchfab and Orthomosaic Comparison
Before we discuss the process of setting up overlays, I want to mention that once our drone construction project is completed, we can export a model for Sketchfab and create an orthomosaic for before and after comparison. This allows us to provide a detailed view of the progress made during the project.
Using Overlays for Comparison
Now let’s focus on how to set up overlays for comparing the before and after images. To do this, we need to use specialized software or tools that allow us to superimpose one image onto another. By aligning certain points of interest in both images, we can accurately compare the changes and progress made over time.
Choosing the Right Software
When it comes to setting up overlays for orthomosaic comparison, there are several software options available. Some popular choices include Pix4Dmapper, DroneDeploy, and ArcGIS. These software packages offer advanced features and precise alignment capabilities, allowing us to accurately compare two or more orthomosaic images.
Aligning Geo Tiffs
To align the Geo TIFFs, we need to identify common features or points of interest between the images. These could include landmarks, buildings, or other identifiable elements. Using the features as reference points, we can adjust and align the images in the software. This ensures that the images are properly overlaid and accurately represent the changes that have occurred.
Benefits of Orthomosaic Comparison
By using overlays and comparing orthomosaic images, we can provide clients with a clear visual representation of the progress made during the construction project. This allows them to see the transformation and understand the impact of their investment. Additionally, it provides a valuable tool for project documentation and future reference.
The Importance of Photoshop in Drone Construction Progression Job

In this article, we will explore the role of Photoshop in this process and how it aids in providing accurate and informative results.
The Process of Opening and Reading TIFF Files
In order to begin the construction progression job, the first step is to open and read TIFF files in Photoshop. These files can be quite large, often exceeding 1.5 gigabytes in size. Once Photoshop opens, the user can drag the TIFF file onto the program for further processing.
Labeling and Organization for Reference
To keep track of the different files and dates, it is essential to label and organize the image layers in Photoshop. This allows for easy reference and avoids confusion. By relabeling the layers with the respective dates, such as “August 20th” or “September 3rd,” the user can quickly identify and distinguish between the different images.
Aligning Images for Comparative Analysis
One of the main goals of a construction progression job is to identify and analyze the changes that have taken place over time. To achieve this, it is necessary to align the images accurately. Initially, the images may not be perfectly aligned, but Photoshop provides a solution through its Auto Align feature. By highlighting both image layers and going to the edit menu, the user can select Auto Align to ensure proper alignment and ease of comparison.
The Purpose of Construction Progression Job
The purpose of a construction progression job is to provide clients with a clear indication of the changes that have occurred on the construction site since the last visit. This information is valuable for tracking project progress, identifying potential issues, and making informed decisions. By recording and documenting these changes through the use of drones and editing software like Photoshop, construction professionals can have a visual representation of the construction site’s evolution.
The Challenges of Handling Massive Files
One of the challenges faced in a drone construction progression job is dealing with massive files. As mentioned earlier, these files can exceed 1.5 gigabytes in size, which can cause issues with storage and processing capabilities. However, with the right software and hardware, such as Photoshop and powerful computers, this challenge can be overcome, allowing for efficient analysis and review of the drone-captured images.
Photoshop plays a crucial role in a drone construction progression job by enabling the manipulation and analysis of images.

By utilizing these tools, construction professionals can provide their clients with valuable insights into the progress and changes occurring on their construction sites.
August 20th: Overcast Day
Looking at the layers panel, we can see that August 20th is turned on. On this day, the weather was overcast, resulting in muted lighting. This affects the color of the images, as well as the level of detail that can be seen. Shadows are less prominent on overcast days, allowing for clearer visibility of objects. However, it’s important to note that this can cause certain issues, such as larger shadows on sunny days.
September 3rd: Clear Skies
Now, let’s switch to September 3rd by turning off the August 20th layer. This day was not overcast, and the difference in lighting is evident in the images. The color of the Orthomosaic has changed, reflecting the ambient light conditions. It’s important to consider the time of day when capturing footage, as it can greatly impact the final result.
Comparing August 20th and September 3rd
By zooming in on the images, we can take a closer look at Site 47, as well as the newly developed Site 48. On August 20th, the construction progress is visible, with the footings and some concrete already in place. By comparing this to the September 3rd image, we can assess the progression of the construction project. It’s important to document these changes over time to track the project’s development and identify any discrepancies.
Using a zoom level of 6.25, we can analyze the images in detail and gather valuable insights about the construction site. This aerial perspective allows for a comprehensive view of the project, highlighting the improvements made over time and identifying any potential issues that need to be addressed.
Orthomosaics and video review play a crucial role in construction projects. By capturing aerial footage and creating detailed maps, project managers can monitor progress, identify areas of improvement, and ensure that the construction is on track. These visual tools provide a comprehensive overview of the project, aiding in decision-making and facilitating communication between stakeholders.
Aligning and Exporting Ortho Images
When working with ortho images in drone construction progression, it is crucial to ensure that the images are aligned properly. To achieve this, it is important to export the images and compare their sizes. If you are using software like WebODM, make sure that the exports match up closely. Using different settings may result in misalignment, so it is necessary to incorporate this into your workflow process.
Tracking Changes Over Time
An interesting aspect of drone construction progression is tracking changes over time. By comparing the ortho images from different months, it is possible to observe any major changes in the construction site. For example, let’s take a closer look at the changes between August and September. While there might not be significant differences in some buildings, it is evident that changes have occurred. However, it is important to ensure that the layers are properly aligned to accurately observe any changes.
Locking Layers in Place
To avoid accidentally misaligning layers, it is advisable to lock them in place. In case you mistakenly drag a layer and misalign it, you can easily rectify the issue by going back to the editing stage and auto-aligning the layers again. Locking layers helps maintain the accuracy and integrity of the ortho images throughout the construction progression.
Considering these factors and incorporating them into your workflow process will enhance the precision and reliability of your drone construction progression job. By aligning ortho images accurately, tracking changes over time, and locking layers in place, you can effectively analyze the construction site and document its progression with accuracy. Remember to pay attention to the export settings and consistently check for alignment to ensure the best results in your orthomosaics and video reviews.
Exporting as JPEG
The next step in the drone construction progression job is to export the current image as a JPEG. This will allow for a smaller file size, as the original image is quite large. It is important to have a smaller version of the image, as it is not ideal to have such a large file on a website.
Aligning the Image
After exporting the image, it is important to ensure that everything is perfectly aligned again. Sometimes, when working with large files, there may be slight alignment issues. By clicking outside of the image, it is possible to realign everything and make sure it looks tidy.
Exporting Multiple Versions
In this particular case, it is recommended to export two versions of the image: one for August 20th and one for September 3rd. Both versions will be exported as JPEGs. These final versions can then be loaded into the presentation page later on. It is not necessary to go through the save process immediately, as this is a casual demonstration.
It is important to remember to add labels to the images. This can be done later in the process, but it is a crucial step. Labels provide additional information and context to the images, making them more informative and useful.
Resizing the Image
The image size of the current project is quite large, with dimensions of 2577 pixels by 16390 pixels. However, when looking at it in terms of inches, the dimensions are 355 by 227 at 72 DPI. This indicates that the image can be resized significantly, providing plenty of room to work with and allowing the clients to easily handle the image.
By following these steps, the drone construction progression job can progress smoothly and efficiently. Exporting the image as a JPEG, aligning everything properly, exporting multiple versions, adding labels, and resizing the image are all important aspects to consider.
