ArcGIS, MapInfo, Integraph_Geomedia, AutoCAD, R2V, MapGis, CityStar, wisdom Founder (now called Yi Shan Hai Hui) digital raster maps (DRG) is a scanned raster map products papier.Après each image playback, the correct play, cards and processing data compression to form in the content, accuracy and color consistency with the file from the network card. Digital Line Graphic (DLG) is a form of vector map data format numérique.Ces cards can be stacked and overlay spatial information to extract attribute data, the vector object attributes or attribute query vector data query object based easy to update and edit and create specific properties and create thematic maps. digital elevation model (DEM) is the number of regional ground elevation which is based on the rules of the projection plane of the map coordinate grid pattern in the plane (x, y) and elevation ( dataset z), which is a geographic information system analysedonnées basic level systèmes.intervalle DEM with the landscape may change in different types, depending on the height of the precision can be divided into different functions qualités.DEM are: analysis of the elevation, slope analysis, coordinate measurement, area, volume, slope, slope analysis, by analyzing visual profile generation, generation contouring, overlay vector data and data related images. digital orthophotos (DOM) is the use of digital elevation model digital photos or digital aerial remote sensing Tuxiang (monochrome or color), the sub-Xiang Yuan 纠正, then for the mosaic of images, depending on the card data generated by the image of the band with the grid Fan Wei.Général km, decoration outline and notes the floor plan. process of producing digital orthophotos: ortho image production are generally chosen by a number of ground control points, the use of images in the DEM data, the image tilt correction at the same time and error correction projection orthophoto production. Can be more Orthophoto Mosaic set the color balance and treatment across a range of cutting the image is orthophoto map. Source.
