摘要：An orthophotomap is an image of the Earth’s surface generated from an aerial photograph or a satellite image that has been geometrically corrected such that the scale of the image is uniform. This photogrametric product,which combines the advantages of a photograph’s tone and measurement possibility,allow a synthetic look at the problem of land management (spatial planning). For this reason,an orthophotomap is more often used as base-map for project purposes. This paper describes the methodology of the production of an orthophotomap for the beltway construction project for the city of Olsztyn. The first part of the beltway project was presented for the local authorities and inhabitants on a satellite map background. The remaining part of the area of interest had not been imaged recently by any high resolution satellite system and had to be completed using recent aerial photographs taken on the scale of 1:8 000. As the project was very urgent,an ordered color orthophotomap for a surface of about 30 km2 with a pixel size of 0.5 m had to be produced within 5 days by 2 persons. Aerotriangulation for a block of 28 photographs placed in 5 strips was completed to obtain elements of the exterior orientation of the images. Two main aspects of further projects are also presented in this paper: - the use of the digital terrain model available in the Central Geodetic Office for the orthocorrection process, - an attempt at radiometric correction of aerial photographs based on spectrally homogenous and regularly distributed samples of pixels.
