The highest qualification for working with remote sensing materials).Extensive experience in creating digital terrain models.Household use of digital modeling in GIS – electronic maps, navigators.Study and quantitative assessment of the current state of the natural environment.Building a digital model of the bottom relief of reservoirs.Environmental problems (including modeling of environmental situations).Construction of highways, highways, and interchanges.Forecasting of landscape processes (where water will accumulate, in which place it is better to plant plants, etc.For mapping purposes to build a digital surface model.Horizontal lines (isohypses) are provided in the following formats: Autodesk DXF, Shapefile SHP, Google KML.an irregular grid.DEM as a TIN model can be provided in the following formats: Wavefront OBJ, 3DS, VRML, COLLADA, Stanford PLY, STL models, Autodesk FBX, Autodesk DXF, Google Earth KMZ, U3D Universal 3D, Adobe PDF.GeoTIFF, Arc / Info ASCII Grid (ASC), Band interlieved (BIL), XYZ, or as tiles in Sputnik KMZ format.The terrain model in the form of a height matrix can be provided in the following formats: vector lines (horizontal lines or other isolines with equal or unequal pitch) networks (height matrix).an irregular, so-called TIN-model (TIN − Triangulated Irregular Network), which includes a certain set of points with elevation marks, which are triangulated taking into account the lines of the discontinuity.a regular matrix (regular or matrix model) of the earth's surface heights (representation on a regular grid of squares, rectangles, or triangles when its nodes are set to the height values).The most common methods of digital representation of terrain are as follows: We transmit the results of the work to the Customer in the required form and format. Transfer of materials to the Customer.
DIGITAL TERRAIN MODEL，DTM SOFTWARE
The specialized software products available at GEO Innoter allow you to obtain a digital surface model (digital terrain model or digital elevation model) in an automated mode, with the accuracy, form and format required by the Customer Depending on the size of the territory and other information about the object, you can choose and order the type of survey, as well as other source data. It is necessary to understand the purpose of creating a digital model of the terrain and elevation model, to know the size and nature of the terrain and the required accuracy of creating products in order to calculate the cost and timing of work, as well as to plan the work. Receiving and approving data from the Customer.Organizing the process of creating a digital terrain model or digital elevation model This dataset has been archived at the NEODC for the use of NERC scientists outside of BGS and CEH (who have made their own arrangements for internal distribution of the data).Sources of initial information about the terrain: a variety of data obtained by geodetic works, topographic survey of the area, stereo photogrammetric processing of aerial and satellite images, laser shooting and radar shooting. The data covering Northern Scotland (North of the Midland Valley) are only available as diff, dsm, dtm and ori products. Products provided include:ĭigital terrain model, enhanced (manually edited to remove embankments etc.) TL63 based on the OS National Grid coordinates of the southwest corner of the square. The dataset covers all of England, Wales and Scotland.ĭata are arranged into Ordnance Survey / British National Grid tiles of 10 x 10 km, each denoted by a 4-charcter name, e.g. It was originally commissioned by Norwich Union Insurance to aid in the estimation of flood risk, but has tremendous potential as a scientific research tool. The data were acquired by the British Geological Survey (BGS) and are for use by NERC funded researchers only. It enabled large areas of the country to be covered rapidly and at very high spatial resolution. NEXTMap Britain digital terrain model dataset, produced by Intermap, was derived from airborne Interferometric Synthetic Aperture Radar (IFSAR).
