OpenDroneMap is an open source photogrammetry toolkit to process aerial imagery (usually from a drone) into maps and 3D models. [3] [4] [5] The software is hosted and distributed freely on GitHub. [6] OpenDroneMap has been integrated within American Red Cross's in-field Portable OpenStreetMap system. [7]
DTED supports many applications, including line-of-sight analyses, terrain profiling, 3-D terrain visualization, mission planning/rehearsal, and modeling and simulation. DTED is a standard National Geospatial-Intelligence Agency (NGA) product that provides medium resolution, quantitative data in a digital format for military system applications ...
The concept of CEP also plays a role when measuring the accuracy of a position obtained by a navigation system, ... For example, a GPS receiver having a 1.25 m DRMS ...
The quality of a DEM is a measure of how accurate elevation is at each pixel (absolute accuracy) and how accurately is the morphology presented (relative accuracy). Quality assessment of DEM can be performed by comparison of DEMs from different sources. [29] Several factors play an important role for quality of DEM-derived products:
Trac is an open-source, web-based project management and bug tracking system.It has been adopted by a variety of organizations for use as a bug tracking system for both free and open-source software and proprietary projects and products. [4]
Electronics errors are one of several accuracy-degrading effects outlined in the table above. When taken together, autonomous civilian GPS horizontal position fixes are typically accurate to about 15 meters (50 ft). These effects also reduce the more precise P(Y) code's accuracy.
Graphical view of the affine transformation. The registration of an image to a geographic space is essentially the transformation from an input coordinate system (the inherent coordinates of pixels in the images based on row and column number) to an output coordinate system, a spatial reference system of the user's choice, such as the geographic coordinate system or a particular Universal ...
A3 LightSpeed processing system consists of a PC server configuration and software, which automatically processes data obtained during flight into photogrammetric mapping products. After a pre-process stage in which the user specifies the required outputs and output specifications, the system solves the AT and bundle adjustment automatically.
