HOW ARE REMOTE SENSING SYSTEMS DIFFERENT?
TEC Imagery Office - FAQsImportant attributes of satellite remote sensing systems include spatial resolution, spectral coverage, and temporal frequency. Spatial resolution describes the level of detail, or smallest size of an object, that can be identified. Spectral coverage refers to how many different colors and different parts of the spectrum are measured. Systems today make from one to seven measurements of light energy for each target area.
Related QuestionsWHAT IS REMOTE SENSING?
TEC Imagery Office - FAQsRemote sensing is the collection or measurement of information about a target without being in physical contact with the object. Aircraft and satellites are the most common platforms for remote sensing observations. The term remote sensing is usually restricted to methods employing electromagnetic energy, such as light, heat, and radio waves, as the means of detecting and measuring target characteristics.

Land Cover Analysis - General FAQsRemote sensing is the measurement or acquisition of information about the Earth by a recording device that is not in physical contact with the Earth. Remote sensing information can be collected in many different ways, including optical (sun's reflected light), photography, laser, RADAR, acoustic, and fluorescent sensors. See the Committee on Earth Observation Satellites Glossary for more information.Related Questions
HOW DOES REMOTE SENSING WORK?
TEC Imagery Office - FAQsRemote sensing satellites collect image data either actively or passively. Radar satellites collect data actively by sending a known signal from the satellite to the earth and measuring the portion of the signal that is returned. A passive device measures the incoming energy, either started at the sun and reflected by the object, or started at the object as a result of its temperature.

Related QuestionsWhat remote sensing software does the ESALab have?
ESALab FAQsRemote sensing software has considerably more capability for working with raster data files than do GIS software packages. If you are working with images consider using one or more of the following software packages: ERDAS Imagine 8.6 Professional (only available to the SNRE ESA Lab), PCI Geomatica 8.0 (available to install campus-wide, see http://gis.umich.edu), and Idrisi 32 (available to install campus-wide, see http://gis.umich.edu).
Related QuestionsIs there an affordable remote sensing software package?
ESALab FAQsYes, Idrisi has an education package that is reasonably priced. The program functions much like ERDAS Imagine and is similar in terms of capabilities.

Related QuestionsWhat does accuracy mean in GIS and remote sensing?
Land Cover Analysis - Technical FAQsSpatial Accuracy is the measure of how well features in a geographically registered layer correspond to their positions on the Earth's surface. This is usually measured by a Root Mean Squared Error (RMSE). For C-CAP applications, an RMSE of one pixel is expected, but often smaller errors are reached. It is possible to reach spatial accuracies of less than one-pixel width RMSE under certain conditions (flat terrain and properly modeled sensor distortion).

Related QuestionsAre there different types of gas cooling systems? If so, what are they?
Frequently Asked Questions About Gas CoolingYes, there are three basic types of gas cooling systems; absorption, engine-driven and desiccant. In Southern California, the most popular systems are double-effect absorption (either direct-fired or steam) and engine-driven gas cooling units. Absorption cooling systems are similar to vapor compression or mechanical systems in that they utilize a cycle of evaporation and condensation of a fluid or refrigerant to produce cooling.
