There are many applications for aerial photography all requiring a specific visual capture…construction progress, traffic and roadway investigation, environmental impact surveys, accident occurence documentation, property development and land use studies, boundary disputes and mapping, agricultural and landscape recording. Each benefits from one or another type of view or sometimes a combination of both.
I work with my clients to determine the use and scope of the aerial imagery they want to capture and provide the proper aerial perspective and that will aid in their project needs. The first step is determining whether the image should be Vertical or Oblique.
Traffic and roadway investigation
Environmental impact surveys
Accident occurence documentation
Property development and Land use studies
Boundary disputes and mapping
Agricultural and landscape recording
Here is the difference between these two types of aerial perspectives.
Vertical Aerial Photo
(taken from the air straight down onto the subject, aerial photo appears like a terrain view on a map)
Vertical aerial photographs show the placement of buildings, streets, land plots and open spaces.
Oblique Aerial Photo
(taken at an angular perspective showing sides of buildings often with horizon in view )
Oblique aerial photos are valuable in capturing the appearance of buildings or other vertical features that rise from the ground such as stadiums, topography, etc as they are shot from an angle and show perspective in relation to the ground and horizon.
