Remote Sensing
Remote Sensing is the art and science of collecting information about an object without being in direct contact with that object. Remote sensing data can be collected from a variety of platforms including satellites, aerial systems, and ground-based systems. These systems have two general methods of collecting data: active or passive. Active systems emit electromagnetic radiation and measure reflectance from an object. LIDAR, which uses light pulses, and IfSAR, which uses RADAR, are two of the most common active systems. Both of these systems are generally used to collect detailed digital terrain data, but also can be used for other purposes. The bulk of remote sensing systems are passive devices that measure ambient electromagnetic radiation emitted or reflected from an object. Airborne photography and most satellite-based sensors (i.e., Landsat, MODIS) are examples of passive systems.
NSTC provides bureau-wide assistance in applying the most advanced remote sensing techniques and technologies toward improved assessment, inventory, monitoring and mapping of resources on BLM lands. Services that we provide include:
Technical Support – From simple software evaluations to assistance with how to use remote sensing in your projects; NSTC staff can help you get the most out of your remote sensing investments.
Data and Technology Evaluations – NSTC staff evaluates, develops, and demonstrates the use of advanced remote sensing technology for a variety of resource applications.
Liaison Support to other Agencies – NSTC staff are working with the NRCS, USFS, NPS, FSA, and USGS to share ideas and technologies to the mutual benefit of all parties. NSTC remote sensing staff can provide technical guidance to BLM managers and support personnel working with other agencies that are performing project work.
Data Acquisition Support – There are many avenues users can take to acquire new remote sensing data products. NSTC can help navigate this maze to get you the appropriate data you need in a timely fashion.
The intent of our site is to provide you with geospatial information and acquaint you with our services. Thanks for visiting ---- we look forward to spatially serving you!
