An orthomosaic is a series of individual photos that are acquired through multiple sources mounted on satellites, Unmanned Aerial Vehicles (UAV´s), and airplanes. These photos are programmatically matched up so that they form a new complete image, consisting of all the collected smaller ones.
digital surface model
The Digital Surface Model (DSM) captures the natural and built features in your field. A DSM is especially useful if you want to examine the crop height and age. This elevation model includes the tops of trees, buildings and other objects. We use this as a canopy model, because we can accurately measure the heights of crops.
digital terrain model
The Digital Terrain Model (DTM) is a digital file providing a highly detailed representation of the topographical variations in the Earth’s surface. The DTM can be combined with other data, such as orthophotographs. A DTM can be used for a lot of different applications, for instance: planning, visualization, height analysis, soil erosion modelling, flood risk analysis, and watershed delineation.
Slope is one of the most widely used surface attributes, it shows the amount of rise over run in a particular direction, usually the steepest path up or down the surface. For each cell, the slope calculates the maximum rate of change in value from that cell to its neighbors. The lower the slope value, the flatter the terrain; the higher the slope value, the steeper the terrain.
We use near infrared imaging to design a Normalized Difference Vegetation Index (NDVI) map that is able to show relative vegetation condition within a field. Through NDVI you can examine crop performance of a field at a single point in time. The graduated scale (red – yellow – green) provides a divergence of colors which makes it easy for you to identify and analyze areas or spots that show poor health.
Contour lines illustrate the shape of areas. They give you a good understanding of the equality of elevation in your field. A contour is a line through all contiguous points with equal height (or other) values. When the lines are close together the length of the gradient is large: the variation is steep. Irregular contours mean rugged terrain.
We provide you with the spatial context for the design, planning and management of critical infrastructure. This allows you to get a detailed overview of the natural and built environment. If the infrastructure is already in place, our Infrastructure Precision Tool becomes a key tool in asset management.
We collect, interpret and provide information about sinks and standing water in and around your fields. When it rains, all of the water is trapped inside the sinkhole and drains into the subsurface depending on the site-specific infiltration rate. We create a hydrological model to simulate water flow.
