The aerial survey is a geomatics method of collecting information by using aerial photography, LiDAR or from remote sensing imagery using other bands of the electromagnetic spectrum, such as infrared, gamma or ultraviolet. It can also refer to the Area of Interest (AoI) identified on the basis of Latitude /Longitude nodes, chart or map made by analysing a region from the air. This is typically done using aeroplanes, helicopter, UAVs/Drones. Aerial surveys can provide information on many things not visible from the ground.

2. The aerial survey is proposed by various government agencies /autonomous bodies for developmental projects and also by private agencies/individuals for private purposes. As per the existing procedure, applications for grant of NoC for aerial photography/surveys received by the Directorate General of Civil Aviation (DGCA) are forwarded to various stakeholders of Single Point Clearance Committee (SPCC) under the Ministry of Defence (MoD) for their recommendations. Bases on the inputs of the concerned authorities, the Ministry of Defence decides upon grant/refusal of NoC for such aerial photography.

3. The newly developed MoD web portal is aimed at facilitating the vendors for submission of applications online€™ for grant of permission for aerial photography/remote sensing survey. The automated/online system will help in reducing the time, bringing in more transparency, accuracy and speedy disposal of applications for grant of NoC by MoD and permission by DGCA.
