Before GPS technology, land mapping was done by personally collecting data of an area that needed mapping. It takes a lot of time for cartographers to complete maps. The advancement in technology has had a great impact on aerial surveying which makes map making easier and time-effective.
In-flight surveys make use of a GPS or Global Positioning System, Infrared and other wireless technologies in gathering geographic information. Through them, experts and researchers no longer have to leave their bases just to collect necessary data from different places including those that are in distant places.
Apart from remote controlled sensing technologies, imaging devices are also necessary to conduct airborne observations and data collections. Although the idea is to have a visual duplicate of an area that is being surveyed such as taking photographs, data collectors require advance imaging equipments, tools and programs for maximum output.
Foggy or blurry images of places would be useless to those who need them. They need blemish-free pictures to come up with an accurate land map of their subject. If this is the case, an association that funds that project will have to acquire additional funds as they have to retake the images.
To avoid unnecessary costs due to useless data and materials, look for devices that are reputed to be top of the line. Although they may cost much, in the long run, they would still be cheaper and more efficient. In case buying is not an option for you, you can still do land mapping through paying the services of those that are already equipped for meticulous jobs such as this.
To know which companies can offer you accurate output, you have to know what the exact technologies and terms are being used to do the job. Additionally, since you will have to pay for their services, you have to make sure that you are familiar with the ins and outs of creating a land map through an airborne survey.
Here are some terms that you need to learn regarding bird's eye view surveillance:
• LIDAR or Light Detection and Ranging
Remote sensing technologies are needed to produce three-dimensional outputs. Airborne surveying companies can avoid spending money on aircraft gasoline and pilots as they no longer have to fly above the area that they have to survey.
• LAMP or Low Altitude Mapping Photography
This is a survey strategy that involves collection of geographic data at the altitude of 300 feet.
• UAV or Unmanned Aerial Vehicle
It is a kind of aircraft that can be controlled remotely. This is very useful when it comes to surveying dangerous terrains or regions.
From the above mentioned survey services, laser scanning is the most effective approach. It was even made better when 3D technology came out in the market. Through it, map makers can have three-dimensional views of the place that they have to map. Digital and 3D maps are created through LIDAR survey.
An aerial survey has great significance in producing quality and accurate maps. Looking for companies that offer airborne surveillance would be a better solution especially if you only have to map one location. To be sure that you'll be working with the right company, familiarize yourself with the terms and technologies that are being utilized in this kind of activity.
