A: For the sake of data security, the desktop does not provide a way to modify the field type. It is recommended to update the source field to the target field using the method of field operation.
04 Jul,2019 iDesktopA: The full map attribute is set in the default attribute of the map. When you overlay cloud service map, you need to cancel the full map attribute. The specific operation is as follows: [map attribute] -- [scope] -- [full map]. Find the corresponding property check box to cancel the default check in the map to cancel the full map display.
04 Jul,2019 iDesktopA: In the dropdown of [Object Operation]——[Break Lines], the second action button is [precise interruption], which can be interrupted by percentage or number of segments. It can realize equidistance segmentation by entering the determined number of segments.
04 Jul,2019 iDesktopA: Right-click on the 3D layer: open the shadow, and then set the sun effect to see how the shadow changes.
04 Jul,2019 iDesktopA:（1）In the "topological error handling options", it is necessary to select segment intersection, which is the basis of subsequent topology processing. （2）Topology processing for topology errors will change in the source dataset. If you want to keep the source dataset, you need to backup dataset before the topology processing. Or you can select "create the middle operating dataset", and the next topology processing operations will be in the middle dataset. And that is also for backup of source dataset. It is recommended that select the check box; （3） Segment intersection operation is to get a real node, and sometimes it gets a fake node by merging the adjacent nodes operation. So you might continue to merge the fake nodes after merging the adjacent node operation.
04 Jul,2019 iDesktopA: Modify the advanced properties of the statistics thematic map to display the maximum and minimum display values for size limits. Before the modification, these two values are relatively small and it needs to be set a little larger. The specific values should be more beautiful than the statistical icon in the figure.
04 Jul,2019 iDesktopA: In the empty space of the menu bar, right click to display the "Map Settings" toolbar, or click "View-Toolbar - Map Settings". Modify the measurement unit through the map settings toolbar.
04 Jul,2019 iDesktopA: Because the map information in the database workspace is stored in a binary form in the smData table, it doesn’t support SQL query. If necessary, you can save the current workspace as sxwu, and then open sxwu as a notepad to view the corresponding layer properties on the map.
04 Jul,2019 iDesktopA: The steps are as follows: （1）Right click the datasource, and right click the "import dataset" menu. The data importing dialog box pops up. Click "add file", and select jpg or tif file. （2） In the data import dialog box, select a line from the file list, and click the "advanced" button in the lower right corner. And the "advanced parameter setting" dialog box will pop up. （3） Set the image coordinate reference file in the "Advanced" parameter Settings dialog box, supporting img, tfw, dom, and smc four kinds of format. Examples and descriptions of these four formats can be referred to "Online Help | Technical Topic | Import and Export Dataset | Image Coordinate Reference File". Other reference document does not be identified.
04 Jul,2019 iDesktopA: 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.
