3D ImageryIn computer vision and computer graphics, 3D reconstruction is the process of capturing the shape and appearance of real objects. This process can be accomplished either by active or passive methods. If the model is allowed to change its shape in time, this is referred to as non-rigid or spatio-temporal reconstruction. Drones can accumulate on demand data of ground profiles and software can crunch the data to present a large land mapping in just hours. This can assist greatly in advantaging farmers, land manager projects, and even in disaster relief. For example, a 3D image can calculate accurate volumes of fill needed to be brought in or removed from a worksite, to better evaluate the after affects of tornado or storm damage and even for developing contour mapping for agriculture and flood management. Traditional aerial photos skew the true distance of spaces and sizes of objects because of the non vertical angle of the imaging detector and the contour of the earth. By using 3D Imagery, and orthophoto technology, the photos are geometrically righted. 3D Imagery can use LIDAR, which stands for Light Detection and Ranging. It’s a “remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. These light pulses—combined with other data recorded by the airborne system— generate precise, three-dimensional information about the shape of the Earth and its surface characteristics.” (https://oceanservice.noaa.gov)
AgricultureDrones in agriculture are a big boon to farmers. They carry the potential of completely transforming and revolutionizing the farming and agriculture industry. Agricultural drones are high-tech systems that allow farmers to do things faster and more efficiently than ever before: soil health scans, monitoring crop health, applying fertilizers and watering the fields, even tracking weather and estimating yields, and then collecting the data and analyzing it for prompt action. In short, drones can mechanize every step of farming, reducing the costs of human errors and enabling farmers to react quickly to threats (such as drought conditions and pests), helping them maximize income and returns on investment in the end.
EducationWelcome to Remote Sensing Technologies, education overview. We are building a knowledge base and technology infrastructure to facilitate collaboration between plant scientists, engineers, growers and government. Our goal is to help scientists and farmers use manned and unmanned aircraft to increase crop yields, reduce production costs and prevent exposure to tedious or hazardous work environments. Specifically we will – ♦ Develop, test and disseminate new methods for inspecting and treating plants, soil and water using unmanned aircraft; ♦ Promote commercialization of unmanned aircraft systems and services unique to agriculture; and land management. ♦ Provide a training program for safe, ethical and cost-effective use of unmanned aircraft as it relates to agriculture and sustainable land management.
Feature ExtractionsTo simplify the data that is collected in aerial imagery systems, a reduction process is needed, in this case called Feature Extractions. Just as professional photographers start with many photographs and then cull them down to the most relevant, feature extractions are simply a digital extraction of redundant data.
Fixed Wing PlatformsFixed wing platforms are a design form that has been around since even before the Wright brothers. Prior to 1903 they were in the form of gliders. Wilbur and Orville Wright found the way to add an engine and powered flight entered the history books. Many of today’s fixed wing drones have taken on a different shape. The most common being reminiscent of the shape of a boomerang. Computer technology has allowed manufacturers to eliminate the tail section and now fly fixed wing tailless UAVs.
ForestryProduction Forests: The practice of forestry with the object of producing maximum quantity of timber, fuel wood and other forest produce is called Production Forestry. The production forestry can be further classified into: Commercial Forestry: Commercial forestry aims to get maximum production of timber, fuel wood and other forest products as a business enterprise. Industrial Forestry: Industrial forestry aims at producing raw material required for industry. In Extension Forestry: Extension forestry which includes the activity of raising trees on farm lands, villages wastelands and community forest areas and on lands along the sides of roads, canal banks and railway lines (Anon., 1976). More recently, there has been emphasis on dynamic land use planning and efforts are made to maximise production on farmlands under agroforestry. Agro-Forestry: Agro-forestry has been defined as a sustainable land management system which increases the yield of the land, combines the production of crops and forest plants and/or animals simultaneously or sequentially on the same unit of land and applies management practices that are compatible with the cultural practices of the local population.
GISA Geographic Information System (GIS) is a framework for gathering, managing, and analyzing data. Rooted in the science of geography, GIS integrates many types of data. It analyzes spatial location and organizes layers of information into visualizations using maps and 3D scenes. With this unique capability, GIS reveals deeper insights into data, such as patterns, relationships, and situations—helping users make smarter decisions. Geographic Information System (GIS) is a framework for processing, and understanding information that is harvested from maps and aerial images of any type, but most commonly satellites and UAV.
What is a Landscan?A LandScan© is the aerial imaging process which gathers multiple levels of data that can be analyzed in order to produce various insights into your land, farm, or constructs. LandScan© reveals the invisible or unobservable things on the ground that are hidden to the earthbound inspector. Whether we enlist satellites, fly manned aircraft, fixed wing drones or rotary drones we have a program established to best fit your needs. Some of the items your program may include are:
- Image analysis and classification
- Spatial modelling and analysis
- Land cover mapping and terrain categorization
- Color balancing, mosaicking, and compression
- LiDAR editing and classification
- Feature capture and update
- Terrain classification, editing, and analysis
- 3D Dimensional Analyses
Land ManagementLand management is the process of managing the use and development (in both urban and rural settings) of land resources. Land resources are used for a variety of purposes which may include organic agriculture, reforestation, water resource management and eco-tourism projects. Sustainable Land Management is based on four principles:
- targeted policy and institutional support, including the development of incentive mechanisms for SLM adoption and income generation at the local level;
- land-user-driven and participatory approaches;
- the integrated use of natural resources on farms and at the ecosystem scale; and
- multi–level, multi-stakeholder involvement and partnerships at all levels – land users, technical experts and policy-makers.
