Remote sensing is the use of technology to gather information at a distance (i.e. without making contact with the object). For example weather radars that detect incoming rain fronts at a distance are a form of remote sensing.
GIS is an acronym for geographical information systems. These are methods of compiling, sorting, analysing and presenting the geographical distribution of differing types of data. For example you could plot time variations in rainfall data against differing geographical locations.

What are the Values of remote sensing in gis?
Remote sensing provides valuable data for GIS by allowing for the collection of information from a distance using sensors on satellites or aircraft. This data can be used to create detailed maps, monitor changes in the environment, assess land cover and land use, and analyze spatial patterns. Remote sensing helps to enhance the accuracy, efficiency, and scope of GIS applications.
Why would amapmarker use active remote sensing instead of passive remote sensing?
A mapmaker might use active remote sensing over passive remote sensing because active remote sensing provides its own source of energy to illuminate the target, allowing for more control over the data collected. This can result in better resolution and accuracy in mapping features of interest.
What is recent technological advances have helped geographer study the earth?
Recent technological advances like remote sensing, Geographic Information Systems (GIS), and mobile mapping technology have greatly assisted geographers in studying the Earth. Remote sensing allows for data collection from satellites and drones, while GIS enables geographers to analyze and visualize spatial data efficiently. Mobile mapping technology provides real-time data collection in the field, enhancing the accuracy and detail of geographical studies.
What is the opposite from remote sensing?
The opposite of remote sensing is close-up sensing, where data is collected from objects or phenomena in close proximity to the sensor or observer. This type of sensing involves direct contact or nearness to the subject being observed, as opposed to remote sensing which involves collecting data from a distance.
What are the four types of remote sensing?
The four types of remote sensing are passive remote sensing (detects natural radiation), active remote sensing (emits energy and measures its reflection), aerial photography (uses cameras on aircraft or satellites), and satellite imaging (capturing images from space using satellites).

What is computer cartography?
Computer cartography is a process of getting information through remote sensing where as again it is sended to (GIS)geo information system.All those given information in GIS is again analysed with the help of computer where as we can see that in that way with the help of remote sensing and GIS map is produced.

Why you need to use cartography in gis and Remote Sensing?
The reason one would need to use cartography in GIS and remote sensing is to be able to create accurate maps for GPS units. This information will give people a better idea of where they are instead of just telling them they're on a flat surface.
