趋势Multi touch 3d gis ——  Windows Platform  | Developer
MTOUCH 3D Gis:It is a large-scale 2/3d integrated gis platform with independent intellectual property rights of Chengdu Trend Electronic Co., Ltd. through gesture multi-touch control; 3d gis (supporting 3DMAX, BIM and other models), force deployment, and 3d situation Deduction, comprehensive inquiry, etc.3d tilt photography of drones,real-time video prevention and control,Fire rescue, public safety, anti-terrorism and explosion prevention, emergency rescue and disaster relief, Traffic accident handling;provide rich secondary development interface.(Recording date January 2016)http://v.youku.com/v_show/id_XMTU4MTI5NTE4NA==.html 
Geographical environment visualization
The system converts survey data into digital elevation model data, assembles high-resolution satellite image data, and generates three-dimensional terrain image data, which can realize three-dimensional terrain roaming and zoom display through multi-point control (two fingers simultaneously press and hold multiple points) Touch the screen and move in the opposite direction at the same time, you can zoom in or out of the map; five fingers simultaneously press and hold the multi-touch screen and move up and down vertically to tilt the high-rise mountain from 0 to 90 degrees; press and hold the multi-touch screen At the same time, it can move from left to right to view the mountain with high level from 0 to 360 degrees and roam the 360 degree panorama.
Electronic map data localization
No need to use the Internet, you can build a three-dimensional geographic information system of the local internal network structure (the highest resolution 0.6M satellite image, 1:2000 and 1:5000 mixed vector electronic map, 30M high-level data); the system can be built on the map Different attributions and utilities are used to distinguish; open the layer function on the map, select a corresponding identifier, all objects of the layer appear on the interface, and indicate with a specific layer symbol that the specified target distance can be read by Near and far layer names and distances. In the mountain layer, through the introduction and modeling analysis of the basic geographic information, the mountain can be analyzed from the top to the mountain, making the mountain analysis more intuitive.
Geographical element information query
The target point query function includes target point name query, target point coordinate query, and all specified layer object queries within the specified range of the target point; the geographic information data carried by the database can be used by relevant personnel to understand relevant information such as important target points; The form is presented, and the information of Jiugongge is customized according to the customer's needs; the important target points can be queried for photos, text descriptions, videos, 3D models, etc. The system also provides comprehensive data system management for specific geographic information objects.
Analytical measurement,path navigation
It can measure the coordinate value, distance, terrain height, azimuth, visibility, area, etc. in the form of multi-touch (moving the two-handed finger to perform the corresponding geographical measurement, and can customize the finger movement and number according to the demand), the shortest Distance function, pop-up setting dialog box, input and select the start point and end point information respectively, the system calls the database data to calculate the length of each path between the two points, and draws the shortest path between the two points with the red line, which can achieve the most between the two points. The choice of excellent path. You can view the length, width, weight, and number of lanes of each road.
3D model import, drone tilt photography
3D scene plotting supports arbitrary placement of 3D models (supporting 3D model cross-sections of large-area buildings in cities), and can adjust parameters such as model position, size, direction, angle, etc.; and allows the labeled models to participate in the project demonstration and realize dynamics. Display of results. UAV shooting, data processing, data import, 3D rendering complete complete solution; direct import of photos taken by drones and related geographic data, after special data processing, can reflect the appearance of features at various angles in the software, Position, height, etc.
BIM 3DS CAD
BIM model data, 3DS model data, and CAD drawings can be imported into the system for presentation, query, statistics, analysis, and disassembly of buildings.
Human eye indoor and outdoor building roaming
The human eye can accurately enter the three-dimensional model to roam the functions of each floor, the main fire protection facilities inside the building, and the key parts.
