Photogrammetry is a field that has seen exponential advancement along with the use of software that can cater to the specific needs of the user. Its compact size and ease to use is an added incentive that makes it the best option to use for structural analysis and 3D representations of any site. The high precision
Photogrammetry is the technique that allows measurement of two points on the land or any other surface using a 2D photograph resulting in a survey map that gives a detailed idea about the spatial distribution of objects on the surface. The conversion of the mapped image can be done using the scale of the photogrammetric
“Geo” is a prefix that comes from a Greek word meaning earth. “Spatial” means relating to space. “Geospatial” is a recently coined terms which is often confused and mixed with GIS (Geographic Information Systems). Both the terms Geospatial & GIS are quite popular and their use is increasing at a significant rate. People often use
An elevation map shows the various elevations in a region. Elevations are usually measured in meters or feet with reference to the sea level. It can be either above the sea level or below the sea level. Elevation in a map is shown using contour lines, bands of same colors or by numerical values giving the
LIDAR is a remote sensing technology that stands for light detection and ranging which uses the pulse from a laser to collect data that helps to measure and create 3D models and maps of distant objects and environments. A LIDAR system works in a way that is similar to radar and sonar but instead of
A contour line is a curve that joins points of equal value. In cartography, contour lines join the points of equal elevation above a given standard level like the mean sea level. A contour map is a map to illustrate the topographical features of an area using contour lines. It is often used to show
