A: You cannot hide 3D globe directly. You can create a new dataset, draw a global region, convert the vector to a single-valued raster data, add the converted raster data to the 3D scene, and set the color table of the raster data layer to white. Then add your own image data to the top layer of the scene set it translucent.
09 Jul,2019 idesktopA: Scales will be reserved in the Mapping for Scales window if you check Fixed Scales and import the required series of scales in the Map Properties window.
09 Jul,2019 idesktopA: 1. delete the tables and sequences begin with sm under the current user; 2. run the statement ALTER SYSTEM CHECK DATAFILES; 3. re-create the datasource. The three steps above can solve the problem.
09 Jul,2019 idesktopA: You can adjust the LOD scaling ratio in the page of the layer properties. The smaller the LOD value, the finer the display of the model data.
09 Jul,2019 idesktopA: There are two ways to modify the picture and text on the splash screen during extension development. (1) Directly set GlobalParameter.SplashFilePath; (2) Replace the Logo_Desktop.gif picture in the bin folder of the installation directory. Please make sure that the new picture should have the same name and format as the original one.
09 Jul,2019 idesktopA: Please set the tolerance value to 0 while constructing the network dataset.
09 Jul,2019 idesktopA: You can open the attribute table of the dataset, select the rows and columns you want to export, right click and choose to export the selected rows and columns into an excel table.
09 Jul,2019 idesktopA: Display the Measure Distance dialog box by clicking Proximity Analysis—Calculate Distance on the Spatial Analysis tab, set source data and neighboring data to the point data, and set the maximum distance to 100 to generate an attribute table. Each record in the attribute table stores the IDs and distance of a pair of points satisfying the condition.
09 Jul,2019 idesktopA: The plot objects are stored in the CAD dataset and the styles of the plot objects are stored in the dataset itself. To modify the style of a plot object, select the object, click to display the Properties panel, modify the style including the line color, the background color, etc.
09 Jul,2019 idesktopA: There is a “Loop” icon in front of the latitude and longitude information. You can switch back and forth between the two formats by clicking the icon directly.
09 Jul,2019 idesktopA: There are two conditions for license lending: (1) Network file license; (2) Available user number for lending. The specific operation is as follows: click the Borrow button in the Borrow and Lend module of the license center, and follow the borrowing process to generate the borrowing file *.id of the computer, copy the file to the lending server and generate the lending certificate *h2r following the lending process. Finally, copy the generated lending certificate to the local machine and activate the license in the license center.
09 Jul,2019 idesktopA: The planar coordinate system with no projection can be converted into a latitude and longitude coordinate system by the means of registration. There are two methods for registration: (1) If there is already a reference layer, open the registration tool, set the registration layer and reference layer, and then puncture the same place in the registration layer and the reference layer, select the appropriate registration method, and perform registration. (2) If you already know the latitude and longitude coordinates of some points on the registration layer, open the registration tool, set the registration layer, and leave the reference layer not specified, pick control points on the registration layer, enter the correct latitude and longitude coordinates, select the appropriate registration method, and perform registration.
09 Jul,2019 idesktopA: There are two ways to convert cad data into SuperMap format data: 1. Import the CAD file as simple datasets, and the closed lines in the CAD file will be converted into line objects if they are not filled region objects. 2. Convert the cad dataset into simple GIS datasets. The data engine will convert closed lines into region objects no matter whether they are filled or not. Therefore, choose the way to convert the CAD file according to your data.
09 Jul,2019 idesktopA: Change the length of the tile in the Layer Properties window to a larger value.
09 Jul,2019 idesktopA: Please check the bounds of the vector dataset. You can try to clip again after re-computing the bounds of the dataset.
09 Jul,2019 idesktopA: You cannot hide the File menu with the configuration file. However, you can choose to hide the File menu by specifying SuperMap.Desktop.Application.ActiveApplication.MainForm.IsFileTabVisible = false during the startup of the program.
09 Jul,2019 idesktopA: Check if there is a graphics card on the computer. For 3D analysis, it is best to use a separate graphics card, not an integrated graphics card.
09 Jul,2019 idesktopA: Create a new field aa in B, and set a unified value (such as 1) for all records. You must ensure that the two datasets have an associated field such as name or other fields. Perform sql query on dataset A, associate the two datasets with the associated field, and then query aa=1 to get the 100 records in dataset A. You can directly delete the 100 records and leave the 400 records.
09 Jul,2019 idesktopA: A snapshot layer is a special layer group. All layers in the snapshot layer group are snapshot layers of the map. The snapshot layer is drawn in a special way. It is drawn only when it displays for the first time. Afterwards, when the map is browsed, the snapshot layer will not be redrawn if the display bounds of the map have not changed, that is, the snapshot layer will not be redrawn with the map refresh. However, if the display bounds of the map change, the auto refresh event for the snapshot layer will be automatically triggered. The snapshot layer is one way to improve the performance of the map display.
09 Jul,2019 idesktopA: You can remove thousand separators for values in the attribute table and values of scales by unchecking Display Thousand Separator on the Environment panel in Options of the File menu. After uncheck the option, you do not need to restart iDesktop to make the settings take effect.
