Aerial photography, surveying, mapping of the topographic map from analog photogrammetry, analytical photography measurements to the current digital photogrammetry. The design of the main elements are: first horizontal control measurements in this region, will use the D and E static GPS measurement methods, elevation control measure fourth-leveling. Followed by the aircraft The aerial survey area aerial photography, aerial photography photo for the region, and then by full digital photogrammetry the system and encryption software in the indoor photo control point encryption, if there is leakage measurement and failed to identify the surface features and landscapes must be necessary and supplementary; compiled into the official topographic maps of the outcome of vector data collected in accordance with the provisions of the schema, norms. Finally, to hand over the whole process every step of the raw data and results data.
