A: The coordinate systems contain three categories: geographic coordinate system, projected coordinate system, and planar coordinate system with no projection.1. Geographical coordinate system: It is a spherical coordinate system represented by latitudes and longitudes. The coordinate unit is generally degrees, and the coordinates have geographical significance.2. Projected coordinate system: It is a planar coordinate system, which is obtained by converting geographic coordinates to a plane thro…
08 July,2019 iDesktopA: Yes, you can remove the suspended solids from the oblique photogrammetry data through the Remove Suspended Solids in the OSGB Processing group on the Object Operations tab when you open a scene in iDesktop 9D.
08 July,2019 iDesktopA: 1. Set the layer editable;2. Select the region object;3. Right click?Properties?Node Info;4. Select the appropriate position to insert a vertex, and modify the coordinates for the inserted vertex.
08 July,2019 iDesktopA: You can edit multiple layers at a time in a map through enabling the Object OperationsàMulti-layer Editing option.
08 July,2019 iDesktopA: Yes, you can prepare a symbol for the line symbol tail. The tail and head of a line symbol can be vector marker symbols, so you can use the marker symbol editor to prepare a vector symbol to server as the tail of the line symbol.
08 July,2019 iDesktopA: Firstly, you need to create a label thematic map for the line layer, and select the name field of the line objects as the expression for the thematic map. Then, you need to save the label map of the line layer as a CAD dataset and append the records of the line dataset to the CAD dataset.
08 July,2019 iDesktopA: If the command for calculating the error is gray, the reason is related to the selected registration algorithm and the number of control points:1. If you select the Offset registration algorithm, then you can only pick one pair of control points, and there is no need to calculate the error.2. If you select the Rectangular registration algorithm, then you can only pick two pairs of control points.3. If you select the Linear registration algorithm, then you need to pick 4-6 pairs of control poi…
08 July,2019 iDesktopA: You can copy the point dataset and add copied point dataset to the map again to replace the original one used to create the label thematic map when the thematic map is ready.
08 July,2019 iDesktopA: You can convert the point dataset into a grid dataset according to the resolution of the grid dataset, and then assign values with the Data Update function.
08 July,2019 iDesktopA: The issue might be caused by an exception of the configuration files. You can delete the C:\ProgramData\SuperMap\Configuration folder and run the program again to generate new configuration files and run iDesktop normally.
08 July,2019 iDesktopA: The cache for Tianditu map loaded in the scene of iDesktop 8C is stored under the C:\Users\User Name\AppData\Local\SuperMap\Cache folder.
08 July,2019 iDesktopA: You can import the EPS data in the format of *.edb with the 32 bit iDesktop software through Start?Data Processing?Import Data?EPS.
08 July,2019 iDesktopA: You must ensure that there is osgb cache data in the scene if you want to use the functions for generating DOM or DSM. Therefore, you need to generate osgb cache for the model cad or model dataset before you add the data to the scene for DOM or DSM generation.
08 July,2019 iDesktopA: The prj format file is the arcgis standard file. Currently, SuperMap software does not allow you to export the projection information into a prj file. However, you can export the projection information as an xml format file. After that, you can compose a prj file with parameters in the exported xml file.
08 July,2019 iDesktopA: Yes, the postgresql datasource is supported. Please note that if the version of the cross software is 32 bit, you need to install the 32 bit pg database. If the version of the cross software is 64 bit, you need to install the 64 bit pg database. You still need to add the bin path to the path variable.
08 July,2019 iDesktopA: When the other layers are in the Clamp to Ground mode, you can see the pipelines under the ground when you zoom out to a certain distance from the ground because the ground surface is composed of arc segments. To solve the issue, you can set the maximum visible height for the underground pipelines.
08 July,2019 iDesktopA: The traffic transfer analysis allows you to find multiple paths. However, if you want to use the optimal path analysis to get multiple paths, you need to perform the optimal path analysis multiple times, with one time specifying the Nearest Distance as the condition and another time specifying the Least Edges as the condition. If required, you can plan other algorithms by yourself, such as setting obstacle points (lines) along the result path from the previous analysis and analyze again.
08 July,2019 iDesktopA: Yes, you can use the command to generate a running report (./licensetool.sh -report /path name/*.report) or use the license center tool to generate a running report, open the report file with Notepad, modify servername to the name of the virtual machine, and then use the report to apply for a license on the official website. You can then create a new directory /SuperMap/License/ on the Linux system, put the license file into the directory, and then you can run iDesktop cross.Note: Make sure t…
08 July,2019 iDesktopA: The wp file is the region file format of mapgis, and idesktop supports the wap format region data. Therefore, you need to use mapgis to output the region data to the wap plain file format, and then import the dataset with idesktop.
08 July,2019 iDesktopA: There are two ways:1. Create a label unique values map, set the style of a label, and move the label through the Move Label command in the Label Map group under the Thematic Mapping tab.2. Convert the label thematic map into a CAD dataset, set the layer editable, and set the style for a label and move it.
