This is our proven cost-effective method of acquiring reliable 2-dimension and 3-dimension spatial information. We take photographs from airplanes or helicopters. Such photos provide a visual evidence of the existing features at a particular point in time.
Other related products that can be derived include digital line maps, digital terrain models (DTM) and orthophoto mosaics. The maps can be produced within the scales of 1:2,000 to 1:10,000 depending on the flying height of the plane or helicopter. Some uses of the products are:-
- Preliminary route planning and design
- Asset management
- Computations (e.g., slope analysis, cut-n-fill and volumetric calculation)
- Map updating and GIS applications
There are also the options to buy existing (archived) photographs or acquire new ones from other sources. Contact us if you are interested in this service.(jc)
