The effects of atmospheric media on thermography will be dependent upon its temperature, density, movement, particulates, etc.
Convection refers to the movement of gas or fluid due to differences in density (gravity, natural convection) or physical force (mechanical convection).
The baseline and responsive documentation-and immediate dissemination-of technical (aerial, hyperspectral, etc.) imagery of flooding is tremendously practical.
Forensic LiDAR and “engineering grade” or “survey grade” LiDAR (LASER Scanning) are very different things. Applications in which engineering and survey LiDAR conventions are manifestly deficient include litigation and its ADR cousins (mediation, arbitration, etc.).
There is no excerpt because this is a protected post.
The images below represent some interesting results from both vertical (orthogonal) and oblique aerial thermography throughout 2018.
The EPA has established a Heat Island Reduction Program (HIRP) and expressed that it is useful for communities in the preparation of projects, programs, and policies. While this language is nurturing vice systemizing, the statement is contained in a section titled “What EPA is Doing to Reduce Heat Islands.” An intent is obvious, and it must be considered that EPA is not a hobbyist organization.
It is a generally accepted principle to adjust the “exposure” of professional thermograms so that the bulk of the selected palette range is confined to features of interest in order to produce the finest representation of their thermal patterning.
Mapping metrologic data assets is frequently necessary, particularly with hyperspectral (other than visible band) imagery and spatial data sets such as LiDAR; the images simply aren’t accessible or recognizable by the general population using ordinary software.
The above aerial photograph is a panorama of the fire’s footprint showing its relationship to downtown Boise, Boise State University, Boise’s Warm Springs Golf Course, the Boise River and Barber Valley, and infrastructure such as the East Parkcenter Bridge.
