The article presents the technical aspects of Digital Elevation Model (DEM) and Digital Surface Model (DSM) built on the basic of Very High Resolution (VHR) data to create orthophotomap in a rapid mapping mode. The final part of the paper is accuracy assessment of orthophotomap built on the same elevation models which were used in a rapid mapping way. In the article were using aerial photography’s gained from digital camera UltraCam Xp by Vexcel. The spatial resolution of this images is 0.10 m. Example data of Gazoport in Świnoujście were processed using photogrammetry software Agisoft PhotoScan. The usefulness of both DSM and orthophotomap products were achieved by cross calculating mean errors. Orthophotomap created in a rapid mapping way, with minimum set of images, was built across using Ground Control Points (GCP). The source of GCP points was the Polish Spatial Data Infrastructure Geoportal. Check points were measured using both geoportal and Global Navigation Satellite System (GNSS) in the Real Time Kinematic (RTK) mode.

The topic of the publication is the presentation of the method of rapid mapping performation. Rapid mapping are performed in special situations, if a terrain is subjected to significant changes or a quick human reaction is needed. Such performation can be available both in paper and digital versions, published on on-line websites – depending on the needs. For rapid mapping almost every type of image data can be used. In rapid mapping different editorial rules are applicable, it is acceptable to make imaging legible with materials of much less detail. A scale of the design is determined based on the interpretation possibilities, and not on the base of predetermined resolution of the design.

This article presents the method of inventory of flood in the real-time GIS system. The method includes: obtaining data, sending data to the server of data base, their analysis in GIS environment and presentation of results. For this purpose the Open Source type of applications were used. The last stage of the presented method is the cartographic development of the hybrid map (orthophotomap with thematic overlays). The authors gave the boundary conditions of these types of studies taking into consideration the data obtained from various sensors of high resolution image systems. The presented method in a complex way describes the development of fast-changing data from the moment of existence of the change, through their acquisition, analysis, to the cartographic development of the map of flood changes

The article presents the analysis of possibilities of using the Digital Elevation (Surface) Models for creation of the 3D cadastre. The authors present the characteristics and meaning of the three-dimensional modelling of objects in the context of solving problems occurring with the traditional two-dimensional cadastre. The paper presents imperfections of the 2D cadastre and indicates possibilities of their removal based on altitude data acquired from the laser scanning. It determines the accuracy of data obtained with lidar techniques and indicates their limitations in specifying the exceeding. As a result of the carried out analysis and theoretical considerations, the authors have indicated the potential possibilities of the usage of Digital Surface (Elevation) Models for the construction of the three-dimensional cadastre system
