3D computer graphics are graphics that use a three-dimensional representation of the geometric data that is stored in the computer for the purposes of performing calculations and rendering 2D images. It is used in due diligence, planing,and mining.Also 3D animation is a powerful presentation tool.
3D mapping is a technology that creates three-dimensional views of objects on computer screens. This type of technology is often used in modern computer programs to provide a life-like view of a place or thing on a map. It provides our clients an aerial view of the areas of interest. This technology is usefull in the due diligence phase of real estate transactions, projects and loan approvals.
Contour lines are lines drawn on a map connection points of equal elevation. If you walk alone a contour line you neither gain or lose elevation. The contour line represent by the shoreline separates areas that have elevations above sea level from those that have elevations below sea level. Our clients can use this to measure the volume of a stockpile, mountain, an irrigation system, road construction etc.
The Normalized Difference Vegetation Index (NDVI) is a numerical indicator that uses the visible and near-infrared bands of the electromagnetic spectrum, and is adopted to analyze remote sensing measurements and assess whether the target being observed contains live green vegetation and the degree of it health.It can also be used to indicate areas that have no vegetation.NDVI is a powerfull proactive tool used to address plant stress before the plant is seriously damaged or destroyed.
A Digital Surface Model helps our clients in making decisions involing field leveling , contruction, and mining at a fraction of the cost and time required when using a trandtional servey team.
A Digital Terrain Model is a topographic model of the earth - terrain relief - that can be manipulated by computer program. The data files contain the spatial elevation data of the terrain in a digital format which usually presented as a rectangular grid.Vegetation, building and other man-made (artificial) features are removed digitally - leaving just the underlying terrain, Our clients can measure the high of objects by compairing the DTM with DSM. This is valueable for planing irrigation systems, leveling rice paddies, mining and construction.
An orthophoto, orthophotograph or orthoimage is an aerial photograph geometrically corrected ("orthorectified") such that the scale is uniform: the photo has the same lack of distortion as a map. Unlike an uncorrected aerial photograph, an orthophotograph can be used to measure true distances, because it is an accurate representation of the Earth's surface, having been adjusted for topographic relief,lens distortion, and camera tilt.
