iDesktop FAQ

A: You can use the text field to do multiple labels thematic map for this dataset, and then respectively set the label to desired colors. Finally, set display filter conditions for each thematic layer according to the text field, to control the display of text that meets the conditions on each layer. Then you can achieve the desired effects.

A: For the underground data, after setting the surface translucent, it also needs to set the data property that is from the underground.

A: There are two ways:  1. [Flight Management]—[Options]—[Display Site]—don’t check.  2. Modify the showroutestop property in the path file (.fpf) to false.

A: The clipping region check box in the map properties tab controls the map display range。 When you set a mask, the map only shows the data in this range, no clipping operation. To perform the clipping operation, please select the map clipping button in the map operation tab, and you can set the clipping result in the pop-up dialog box.

A: There are many geographical coordinate parameters. You can export the projection data and the latitude and longitude coordinate system that needs to overlay display. Then compare the two geographic coordinate systems to check whether there are different other parameters. If it is different, modify it and then overlay.

A: In this case, you can check the nodes of the routing line object to see if there is a single routing value corresponding to the different nodes. The correct routing data requires that every routing value corresponds to a unique node. Because the line data that generated the routing data has the redundant points. You need to make topology processing for the original line dataset before generating the routing data, removing the redundant nodes.

A: The sql condition in Oracle doesn’t support double quotation marks. For charactertyped fields, please use the 'Beijing' format when determining a field value.

A: In the computer region and language-administrative-change system locale, please set the current system locale to Chinese (Simplified, PRC).

A: You can use the map clipping. Select an administrative area, and use the "map operations - clipping - select object area clipping" function. Check the save map box, and you can save clipping part as a new map.

A: When drawing objects in Auto CAD, there are parameterized objects. When you import the CAD datasets, the parameterized drawing and storage mode will be reserved. Thus the longitude of the object length and area is reserved.

A: Small object in the layer: the height and weight of the minimum enclosing rectangle of a geometry object in the layer is smaller than the object minimum display size (it refers to the size of the screen coordinates), then the geometry objects are not visible. This feature applies not only to normal layers, but also to thematic layers.

A: This is due to the setting of terrain exaggeration; the terrain scale is achieved by scaling the terrain elevation. That is to say, when the terrain is exaggerated, the elevation changes, so the measurement distance will change.

A: It is generally due to the high Z value of the model when making the model. Use the "Move Tool” of 3ds Max to select the model and check the coordinate information, and modify the model elevation to 0.

You can get the 2D map shadow effects by setting the offset for the thematic map layers. When making a single-value thematic map, locate to the "Advanced" tab and set the offset in the offset parameter setting.

A: In the flight management tab of desktop, uncheck the boxes of display sites and display path in the options tool group.

A: Yes. After you selected the legend object, you can split the legend to multiple subobjects through [Layout Format]-[Split]. When you manually adjust the display style and order of sub-objects, you can combine the required sub-objects again.

A: Vector caches don’t save the style. 1. You can save the style through the scene caches. 2. The 2D style configured in the scene won’t be saved. It is recommended to load the map or the map caches to the scene after you configured the 2D data to the map.

A: layers member provides the methods of MoveTo, MoveDown, MoveUp, which can move the layers order.

A: You can use the Color.FromArgb method. For example: GeoStyle3D style = new GeoStyle3D(); style.FillForeColor = Color.FromArgb(125, 250, 250, 50).

A: It may be the coordinate system. If the data is a plane coordinate system with no spatial reference, the export will fail. If the data is a geographic coordinate system or a projection coordinate system, the system will automatically convert it to the WGS84 geographic coordinate system.
