MONITORING LEGAL BOUNDARIES
Legal boundaries such as tax and property evaluation can be explored by the use of remote sensing of land use and land cover. An example of evaluating property ownership is a study conducted in the Philippines. According to the study, the Philippines' most valuable natural resource is land, with fifty percent of it that is arable for a population of sixty five million. In 1989, three areas were selected in the study for baseline aerial photography of lands to help prove ownership and tax assessment. All the photographed lands, information of ownership, and every land enhancement/destructing for tax purposes would be marked in the TYDAC SPANS ...view middle of the document...
The target area observed was Chang Mai Province, Thailand, via Landsat Thematic Mapper and the Advanced Land Observing Satellite/Phased Array type L-band Synthetic Aperture Radar. What makes this study appealing is that this particular region is usually covered in clouds or experiences heavy rain, making an accurate mapping of the area difficult. The study concludes that the use of multi-sensor remote sensing of land use and land cover of an area is necessary for an area that experiences rainy seasons, like the northern part of Thailand. The study found that the radar imaging is what made the data recording process much more accurate because the equipment can operate in any season.
Another capability of remote sensing land use and land cover is the the ability to detect objects on the ground. A study that chose to explore expert level target detection in West Lafayette, Indiana. The study used digital airborne natural-color orthophotography and Definiens Professional 5.0 software to capture and discern captured images of West Lafayette. The study found that using aerial orthophotography was very accurate and detailed when it came to land use and land cover mapping. The accuracy allowed for object-oriented classification and also avoided the salt-and-pepper distorting effects in slightly distorted images. This explains why people, agencies, and governments use unarmed drones to monitor areas because of the accuracy of the images/data they collect. The study found that the fewer spectral bands and values used in image collection the more geometric and spatial information that is needed for the ground targets/objects.
It has been discussed that the two main purposes of remote sensing land cover and land use are to establish a baseline of information and to observe changes over time. Some of the most critical uses of land cover and land use remote sensing are target detection, establishing baseline information, monitoring legal boundaries, logistics planning, delineating damage, monitoring urban expansion, management natural resources, monitoring long term changes, and protecting wildlife habitats. Most of the information gathered are from aerial photographs and satellites like the Landsats. Some of the most critical uses of this technology and specific mapping detail is prevent social unrest like how the Philippines collects areal photographs and maintains a GIS of tax and ownership information, the use of satellites to delineate damage after a natural disaster like how China used its Beijing-1 to survey Sichuan Province after a major earthquake where emergency responders could find manageable roads and the hardest hit areas of damage either natural or human buildings, and the overarching theme that has been presented is that a lot of this remotely sensed data is observing humanitarians impact upon the environment that is around them with significant...
