Analyzing Information through Remote Sensing & Geographic Information System

A geographic information system is a computer-based tool for recording and studying feature events on Earth. It combines common database operations like query and statistical assessments with maps. This system manages location-based data and provides tools for study and display of different statistics, including types of vegetation, economic growth opportunities and population characteristics. It allows you to link maps and databases to generate dynamic displays. GIS also provides tools to visualize and overlay those databases in ways impossible with standard spreadsheets. These capabilities set GIS apart from other data systems and make it beneficial to various private and public enterprises for planning strategies, forecasting outcomes and explaining events.

Remote sensing, on the other hand, pertains to the process of making measurements of the Earth through sensors on satellites or airplanes. These sensors gather information in the form of images and offer specialized capabilities for visualizing, studying and manipulating those images. Images obtained through remote sensing are integrated in a geographic information system.

The combined data from remote sensing & geographic information system can provide new information that might not have been accessed from only one layer. For instance, a density map can be used to see the number of mobile phones in an area and then that piece of information can be combined with another layer showing the amount of mobile phone towers in order to determine the best area to put up a new tower. To find out if the new tower will obtain great reception, a third layer only needs to be added like an elevation map and the location of the proposed area should be discovered.

Being able to integrate and study layer data from various sources helps uncover concealed information on a map. This piece of information might be hard to visualize in other forms like in a chart or graph. With remote sensing & geographic information system, you don’t need to worry about such matter.

GIS can also be used to study environmental impacts and problems. Combining hydrography information with soil data can help you determine the kind of materials like pesticides and agriculture fertilizer that could be traveling to the streams and rivers. This helps you determine the direction they might run off to and the impact it could cause to the environment. A conservation map can be added to your efforts. This way, you can also determine the nearby communities that are affected by the toxic waste. All you need to do is to combine the information with a census map to determine who are using the water and what they’re using it for.

A geographic information system also provides a strong foundation for building and integrating cartography with geospatial information, making it possible to provide comprehensive solutions and solve difficult issues that people previously didn’t have any idea of. Remote sensing & geographic information system are quickly gaining recognition in various research fields and are being used by an increasing number of professionals as more people learn about the benefits that these tools provide.
