A: Resetting projection is mainly for setting the coordinate system. It will not change the geometric coordinates of an object. For example, the x, y coordinates in original data is the reference value in the projection coordinates system. The reference value is bigger, after you reset the latitude and longitude coordinates, the original data coordinates will not become a latitude and longitude; The XY value of the original data will be changed after the projection transformation.
04 Jul,2019 iDesktopA: Yes. You can use the location replication feature, which enables cross-layer operations. Turn on the "multilayer edit", and set each layer to be editable. Select the object to be moved, and click the "location copy" function, then you can locate and copy multiple objects to the specified location.
04 Jul,2019 iDesktopA: The property window is a floating window. If you drag the properties window out of the screen, you will not see the pop-up window when you double-click on the geometric object. You can open the desktop installation directory file \WorkEnvironment\Default\SuperMap.Desktop.Frame.config, and modify the [in the bottom of the file.
04 Jul,2019 iDesktopA: Because the client's point dataset does not match the line segment (the point is not on the line). The tolerance of the network can be set for reasonable matching.
04 Jul,2019 iDesktopA: SuperMap adopts the method of passing in host address, so it can’t recognize the computer name and localhost. If the server is local, the service address can be connected without written, or written as 127.0.0.1.
04 Jul,2019 iDesktopA: After the model is loaded to the scene, right click the mouse button “Generate Scene Cache”, and then select the cache types for OSGB cache. Finally set the cache path. The LOD level is set according to the requirements. Click the generate button.
04 Jul,2019 iDesktopA: The UDB datasource is a local file datasource that stores multiple datasets of different types. When you create a new UDB datasource, it will generate two files at the same time, udb and udd. The udb file mainly stores spatial geometric information of spatial data, while the udd file stores attribute information. Compared with previous SDB datasource, the UDB datasources have the following advantages: 1. massive data throughput capacity; 2. cross-platform data sharing ability; 3. efficient reading and writing ability; 4. it adopts multiple technologies to ensure security, such as: double-layer encryption mode; CAID mode storage operation; 5. Cross-threaded operation. But it does not support multithreaded simultaneous access.
04 Jul,2019 iDesktopA: There may be the reason: The data table in dataset is deleted, but the records are still in the SmOspRegister and SDO_GEOM_METADATA tables. So it failed to delete the dataset. The solution is: you can delete the records corresponding to the dataset in SmOspRegister and SDO_GEOM_METADATA tables through the database viewing tool.
04 Jul,2019 iDesktopA: The reason why the site was not imported successfully is that the distance between the point and the arc of network dataset exceeded the node-capture tolerance, and it could be imported successfully if the node-capture tolerance was modified.
04 Jul,2019 iDesktopA: kml is an XML-based syntax and file format, used to describe and save the geographical information such as points, lines, images, broken lines, and opened in desktop scene. It can also be used to open the 3D model data. The supported model files: .3ds, .sgm, *.mesh.
04 Jul,2019 iDesktopA: 3ds is a kind of 3dsMAX model format. You can load it to the iDesktop in the way of kml. You can also import to the 3D symbol library.
04 Jul,2019 iDesktopA: It is a 3D model storage format provided by SuperMap. It can be loaded to the scene in the kml format. It can also be loaded to the 3D symbol library and stored to animation model, and the file is encrypted to protect the data security.
04 Jul,2019 iDesktopA: The field name in (select max (the field name) from the dataset name).
04 Jul,2019 iDesktopA: Data replication is not successful because the cad dataset is the record stored in the longblob format in mysql. For the large data, it needs the mysql to modify the configuration file and the configuration file. You can expand the max_allowed_packet file in my.ini configuration file according to the data size. Restart the mysql service.
04 Jul,2019 iDesktopA: The font can't be out of range, so you can make it a little bit less high in Stroke Management > Text > Attribute. Just don’t drag characters out of bounds.
04 Jul,2019 iDesktopA: Generally, it is caused by the inconsistent coordinate information between the additional dataset and the target dataset. So it is ok to add them in a consistent way.
04 Jul,2019 iDesktopA: After the new oracle database is created, the oracle datasource must be created before the oracle datasource is used on the desktop. The system table must be established before oracle can be opened.
04 Jul,2019 iDesktopA: Use the UPPER function: UPPER(field) = UPPER(the imported parameter).
04 Jul,2019 iDesktopA: First transform all the layer datasets in the map. Convert them to the needed projected coordinate system, and then open the map. Set the dynamic projection of the map to the required projection coordinate system, and save the map.
04 Jul,2019 iDesktopA: Register the event after the main form is loaded when the plug-in is initialized. Set the event: Application.ActiveApplication.MainForm.RibbonManager.SelectedTab = Application.ActiveApplication.MainForm.RibbonManager.Tabs[3]; you can set the custom tab.
