Six-thousand, Nine-hundred and Thirty-Six Feet from the top exactly. Did you ever wonder what the elevation at the top of the Grand Canyon is, you know..., just in case of a fall? Hopefully this should answer your questions.

What is orthophotography and Lidar?
So what is orthophotography then? Well exactly defined orthophotography is a "Photograph having the properties of an orthographic projection. It is derived from a conventional perspective photograph by simple or differential rectification so that image displacements caused by camera tilt and terrain relief are removed." for a list of definitions on this matter visit http://www.maps-gps-info.com/maps-gps-glossary-o.html. To get a better idea of one looks like I have posted a picture to the right for your viewing pleasure.
Lets talk about Lidar shortly. Lidar is how we get topographic maps. Imagine if you wanted to know what the Grand Canyon looked like; to find this out you would look at contours on a map. Imagine that you had to draw everyone of these contours. Instead of having to draw multiple contours, there are sensors that can do this for us. By attaching a sensor to an aircraft, and flying the mission, it is possible to figure out these contours by basically scanning the canyon without actually having to go into it, just by using a laser. Simply explained that is lidar. I highly recommend the article The uses of LiDAR technology.
Basically in brief that is orthophotography and LiDAR. These are both a form or aerial survey. Without the aircraft and the sensors, finding out what our physical earth actually looked like would take longer. In all the technology is there and it works. Without this technology, we would be surveying contours every 50 feet and would not even have a way to see it from the top. Although there is nothing wrong with this, it give those such as engineers, land managers, and GIS databases among others a valuable tool.

Local Weather Report
Check out the Local Accuweather Weather in the weather widget and you will notice that aerial survey is near impossible here in the southwest. One of the things to consider when planning a mapping mission is how much visibility is required to complete a mission properly. Not only is the visibility less than three miles, the cloud base in most of the southwest is about 2000 feet above the ground. To complicate matters, if ground visibility is important at the time of the mission (and it usually is), then the ground is almost all white today due to continued snowfall. That makes finding those white ground control points slightly difficult, and aerial photography nearly impossible.

Company Profiles
You will notice that at the top of the page there is a links box titled Aerial Survey Companies Worth Noting. Everyonce in a while there are companies that are distinguishable for some reason or another. It is my intent in this blog to find out what makes them stand apart from the competition. Is it their history, expertise, technology,.... This is what we shall find out together. If you feel that there is a company that should be added to list, feel free to leave a comment. The goal will be to profile one company a month.

How are Aerial Surveys Gathered?
There are many ways to gather aerial surveys and historically in the past, even pigeons have been used. Typically aerial surveys are gathered through the use of an aircraft such as the one shown (operated by Keystone Aerial Surveys Inc.) in the picture in this post. You will notice it is necessary to cut a hole in the aircraft to mount the camera. This type of platform will give you high resolution photos, which can be used in many various applications. These applications include everything from engineering to forestry and even more.
For a more detailed explanation check out the article called "Remote Sensing Survey Strategy" at http://www.searchmesh.net/default.aspx?page=1726.

Welcome to the Aerial Mapping & Aviation Methods and Technologies Blog.
Welcome to the Aerial Mapping Aviation Methods and Technologies Blog. I hope you find this blog of interest in the fields of Aerial Mapping, Photogrammetry, surveying, GIS, and many more subjects along this line of thought to also include aviation safety. We will discuss the mapping industry, its methods, history, and technology and how it affects us in our daily lives. We will look at many interesting diversions in many different formats. I am glad you could join me, and hope you find it informative
