Taking SPOT 5 image as an example,this paper mainly discussed the producing procedure of remote sensing digital Orthophoto maps and the image fusion.

Producing Color-Digital Orthophoto Map by Auto-Aerotriangulation Method;

Basic requirement,generative methods and content examination of making digital height model and digital orthophoto map are introduced.

Based in the Fuzhou 2,000 color digital orthophoto map production.

Discussion on Several Technical Problems about Producing DOM;

Facture and Quality Control of DOM

A few examples are given: DOM can be used to help the designer and decision maker to plan and select correctly the layout and position of Beijing Olympic sites, the thermal infrared map and land cover map can be utilized to provide the ancillary information for planning the green land, and the technician of 3d Vr can be employed to display the structure of the planned Beijing Olymp.

The paper presents some expertise of manufacturing digital elevation models and digital orthophoto maps by the complete digital photogrammetry system of VirtuoZo NT and JX4c DPW,and treats of the subsistent major technology and main technical problems in the production processes of the digital elevation models and digital orthophoto maps.

Having experienced the ways of field survey on the spot and eyed-interpretation on optical image, the survey technique on soil erosion entered a new stage of using digital remote sensing imagery.
