A: You can add the text in a text dataset to the attribute table using the function of converting text to field.
08 Jul,2019 idesktopA: Yes, you can. Firstly, you need to open the attribute table of the text dataset, select all records in the attribute table, right click and save them as a tabular dataset. In the tabular dataset, you can find fields for bounds of all text objects: SmSdriN, SmSdriS, SmSdriW, SmSdriE. Create double-precision attribute fields X, Y, and update the column with following formulas: X= W+E/2; Y=N+S/2. Then convert attributes to points using field X and Y as coordinates X and Y.
08 Jul,2019 idesktopA: The client connection failed because you had not given the server IP permission. You need to grant the permission to IP so that the IP address can work as 127.0.0.1. In the pg_hba.conf file under the data folder of the PostgreSQL database installation directory, please add “host all all 0.0.0.0/0 md5” after “host all all 127.0.0.1/32 md5”.
08 Jul,2019 idesktopA: Firstly, add the terrain data to the map, use the grid query function to check if the slope value of the data is 0. If it is 0, the data itself has errors. If it is not 0, the reason is that the 3D display system of the computer is not discrete graphics card by default. Please check the 3D display system of the computer and set the NVIDIA Graphics for the default 3D display via Computer—Management--Device Management--Display System.
08 Jul,2019 idesktopA: It is mainly because that the osgb scene cache does not support two-dimensional symbols in the scene. If you want to use osgb scene cache, it is recommended that you use 3D objects and 3D symbols; otherwise create the vector scene cache for the data.
08 Jul,2019 idesktopA: The name of the new dataset created with SuperMap iDesktop after version 8C is inconsistent with the corresponding data table name stored in the oracle database. The corresponding table name is SMDTV_N (the part before "_" is the same for all data tables, and N is consistent with the ID of the dataset in SMregister). The name of the corresponding data table can also be viewed in [Property Info] of [Properties] of the dataset in the desktop software.
08 Jul,2019 idesktopA: For the oblique photogrammetry data, individual model extraction is achieved with the help of the corresponding vector region data. The precision of the vector significantly affects the precision of the individual model extraction. Specific steps are as follows: firstly, add the oblique photogrammetry data and the vector region data to the scene together, select the region vector layer, right click to modify the object selection style, check the Clamp to Object option, and set the layer to transparent for better display effect. Then, come back to the scene to select a model to highlight it and double click to display the properties of the model.
08 Jul,2019 idesktopA: Select the label thematic map, right click, click Modify Thematic Map, and set Precision to 2 digits of decimal points in the Effect Settings area.
08 Jul,2019 idesktopA: You need to place the vector region layer to the top level of the scene.
08 Jul,2019 idesktopA: By default, the table name and the dataset name are different in the 8C version. In the 8.1.0 version, to make them the same, you can open the /bin/SuperMap.xml file under the installation folder of iDesktop and change false to true for the DTNameTablaNameSame parameter in the row of 143.
08 Jul,2019 idesktopA: The display boxes display the X and Y values of the mouse under the current coordinate system. You can press the Tab key to input the X and Y values and confirm the node. If you want to hide the display boxes, you can disable Parametric Drawing in the [Drawing Settings] list on the Object Operations tab.
08 Jul,2019 idesktopA: You can use the Attribute Update function from the Data tab to get the numbers of hospitals using region objects for counties. For specific settings of parameters, you can check the help document.
08 Jul,2019 idesktopA: (1) You can use the service area analysis in the network analysis. Select residential points as service points, set service radius to 2 km, and you can find the result in a CAD dataset of a temporary datasource. You can copy the result dataset and convert it into a simple region dataset. (2) Finally, you can find areas with more than 3 overlaps through topology checking. Those areas can serve as the candidate areas for shopping malls. For topology checking, you can firstly perform the topological checking with the condition No overlap within region on the simple region dataset obtained from last step. Then, perform the same topological checking again on the result of the first topological checking operation. Finally, perform the topological checking with the same condition again on the result of the second topological checking operation to get areas satisfying the conditions required.
08 Jul,2019 idesktopA: To achieve the effect of selecting units of different floors, you need the vector regions for each floor. For a building of 5 floors with the bottom altitude at 0 meters and the height of 3 meters for each floor, you need 5 overlapping regions for all the 5 floors. You should create two fields to store the bottom altitude and extruded height respectively. For the 1st floor, set the bottom altitude to 0 and extruded height to 3. For the 2nd floor, set the bottom altitude to 3 and extruded height to 3. You need to set values for the two fields for all the 5 regions for the 5 floors and add the data to the scene. After that, set the Altitude Mode to Relative to Ground, set Bottom Altitude and Extension to the corresponding fields. Finally, check Clamp to object while setting the Layer Selection Style for the layer.
08 Jul,2019 idesktopA: You can add two layers, and set labels of higher priority to display at one scale and labels with relatively lower priority at the next scale with the help of filter display settings.
08 Jul,2019 idesktopA: Two display modes are offered for color ramps: random and gradient. You can select the color ramp from Color Scheme and specify the display mode.
08 Jul,2019 idesktopA: Yes, you can. Even though you cannot generate scene cache for image collection datasets, you can choose to generate vector map cache and then add the vector cache to the scene.
08 Jul,2019 idesktopA: Yes, you can. You can right click a grid dataset layer, click Set Color Table, and add an item for the specified grid value.
08 Jul,2019 idesktopA: You can specify a region dataset for Visible Bounds in [Image Properties] of [Properties] of the image dataset to display the imagery dataset within the bounds of the region dataset specified. 1. What should I do if some of the labels of the point data in the published map service cannot display completely? A: If it is a point is on the boundary of the dataset, the label of the point will exceed the boundary of the dataset if the label is too long because the label itself occupies a certain range of circumscribed rectangle. Therefore, after the map is published, the part of label goes beyond the boundary of the dataset will be intercepted. To solve this problem, draw some points beyond the boundary of the dataset after setting the layer for the dataset editable to expand the dataset boundary, and then delete the points. After that, when you publish the map, the problem will be solved.
08 Jul,2019 idesktopA: Firstly, you need to save the label the thematic map as a CAD dataset. Then, you can export the CAD dataset into excel format data.
