The goal of photogrammetry is to correct relief displacement in an image through overlapping stereo images. This is why planes zigzag over the same areasimilar to how a lawnmower cuts the grass. The multiple camera angles create the necessary overlap and parallax. PARALLAX:Stereographic parallax is...
In the formula, you can see how NDVI leverages near-infrared (NIR). So when we put the NIR band to display as red, we getcolor infrared. We say color infrared because near-infrared is in the red channel. As you can see below, the pivot irrigation vegetation should already be shouting ...
In close-range photogrammetry the sensor is often close to the object of interest and is typically not nadir viewing, but rather looking horizontally, obliquely, or even upward in the case of mapping bridge engineering structure. This imagery is modeled mathematically in slightly different ways, hen...
DSMs can be opened and manipulated in Google Earth Pro, ArcGIS, QGIS, AutoCAD Civil 3D, Infraworks, and many other GIS programs. DTM (.tiff) This is a vector data set composed of regularly spaced points and natural features such as ridges and break lines. A DTM augments a DSM by ...
DTM—Digital elevation of the earth, not including the elevation of any objects on it. This is also referred to as bare-earth elevation. The bare earth DTM dataset is used to produce the orthoimage and orthomosaics. DSM—Digital elevation of the earth, including the elevation of objects on...

In spatial analysis, a raster frequently refers to an orthoimage or the photos taken from aerial devices orsatellites. Digital Terrain Models (DTM) and Digital Surface Models (DSM) also incorporate raster geospatial information. These models contain geospatial (raster) data about the earth's surface...
The idea behind LiDAR is quite simple: point a small laser at a surface and measure the time it takes the laser to return to its source. This technology is used in geographical information systems (GIS) to produce a digital elevation model (DEM) or a digital terrain model (DTM) for 3D...
