Today, we're going to learn about the origins of photogrammetry. Has anyone heard of Aime Laussedat and his contributions?
Wasn't he the first to use a camera for topography?
That's correct! In 1851, Laussedat created a camera designed specifically for measurement. It's fascinating how photography evolved from there. Can anyone tell me what Nadar is known for?
He took the first aerial photograph, right?
Exactly! In 1858, Nadar captured his aerial photo from a balloon. This introduces the concept of taking images from above—a crucial aspect of photogrammetry. Let's remember 'AL-N' for 'Aime Laussedat and Nadar,' a way to recall these two pivotal figures.
What did they do with aerial photography?
Great question! They initially used it for topographical mapping, which laid the groundwork for many applications we see today, including military and civilian uses.
Now, let's talk about the various techniques that came after Nadar. Who knows about the use of kites for aerial photography?
I remember hearing about Archibald's kite photos!
Exactly! E.D. Archibald was one of the first to take kite photographs in 1882, and by 1889, Arthur Batut also utilized this method for aerial images. They truly expanded the possibilities of aerial photography beyond balloons!
And what about the rockets?
Excellent point! Alfred Nobel used rockets in 1897 for aerial photography, which was innovative at that time. This highlights how creative approaches were taken to capture images from the air.
So far, we've discussed peace-time applications, but what about during conflicts? How did aerial photography evolve during the World Wars?
Didn't they use it for creating battle maps?
Absolutely! Aerial photographs played a crucial role in mapping and strategizing during World War I. For instance, Sherman Fairchild took overlapping images to create detailed maps of Manhattan!
So, aerial imagery was essential for military operations?
Yes, indeed. They used aerophotography extensively for reconnaissance and mapping, which paved the way for the advanced surveying and mapping techniques we use today.
Now, let’s transition to the technological advancements in photogrammetry. Could anyone explain what happened from the 1950s onward?
Was this when computers started being used in photogrammetry?
Exactly! Analytical photogrammetry marked the beginning of computer use for accurate measurements. It introduced improved aerial triangulation methods.
And digital photogrammetry?
Digital photogrammetry—now that’s the current phase. It processes high-resolution images using specialized software, significantly enhancing accuracy and efficiency. Remember the acronym 'DICA' for Digital Imagery with Computational Aids.
In eighteen fifty-one Laussedat did come, measuring with cameras, the world in a sum.
Once upon a time, a balloonist named Nadar flew high above village sights, snapping pictures that changed the world forever.
Remember 'AL-N': Aime Laussedat and Nadar for the early names in photogrammetry.

The art, science, and technology of obtaining reliable information about physical objects and environment through processes of recording, measuring, and interpreting photographic images.
The process of taking photographs from the air using various platforms like balloons, kites, airplanes, or drones.
The phase of photogrammetry that began in the 1950s, focusing on accurate photogrammetric measurements using computer technology.
A method using digital images processed through specialized software to derive photogrammetric information.
The method of determining the location of points by measuring angles and distances from known points.
This section covers the historical milestones of photogrammetry, from its origin with early experiments in photography to the advancements in digital photogrammetry.
The historical developments of photogrammetry highlight key figures and innovations from the formation of the first measuring camera by Aime Laussedat in the mid-19th century to the integration of advanced computational methods by the late 20th century. The narrative includes significant milestones like the introduction of various aerial photography techniques and the evolution into digital photogrammetry that drastically enhanced accuracy and efficiency.
The history of photogrammetry can be traced back to the pioneering work of Aime Laussedat in 1851, who created the first measuring camera for topographic applications. In 1858, Gaspar Felix Tournachon, also known as Nadar, captured the first known aerial photograph from a hot-air balloon above the small village of Petit-Becetre. Following this, several notable individuals contributed to the evolving field. For instance, E. D. Archibald was among the first to use kites for aerial photography in 1882, and Alfred Nobel utilized rockets for aerial images in 1897. The development accelerated with innovations like Julius Neubranner's pigeon-mounted cameras in 1903 and L.P. Bonvillain's aerial photography from airplanes during 1909.
The evolution of photogrammetry can be categorized into four major phases:
Understanding these historical aspects is crucial not only for appreciating the technological advancements but also for applying photogrammetry effectively in current practices.
