GIS and Remote Sensing
According to United Nations, “Remote sensing (RS) is the science of making inferences about material objects from measurements, made at distance, without coming into physical contact with the objects under study”. Figure below shows the flow of simple remote sensing system. The essential elements of the remote sensing are (1) plateform–airborne (aircraft, balloon, UAV) or spaceborne (satellite, spacecraft)–carring the instrument/sensor, (2) ground target–earth surface (land, ocean) or atmosphere–under investigation and (3) the instrument/sensor to acquire data.
After study design one of the most important task in remote sensing is planning of data acquisition. Any remote sensing data acquisition system consist of the selection of three major aspects: (i) platform (spaceborne, airborne), (ii) remote sensing system (optical, SAR) and, (iii) sensor (data from any specific satellite/airborne/UVA sensor).
What We Need?
The only thing we need to know from you for data is the geographical location and extent of the area where you want to acquire the remote sensing data.
- Fresh acquisition: we can plan/order single or multi-temporal data for the selected study area
- Archive data: we can search and order archive data (if available) in order to reduce the cost
- Free data: we can also provide you with the best available free remote sensing datasets (depending on the type and requirements of the study)
