FAQ

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.

A: Please check the raster/image dataset coordinate system. It requires all raster datasets or image datasets to have the same coordinate system.

A: The label expression that implements this effect in the UDB datasource is: “AREA”||” km#+2”. And you need to check the display upper and lower marks.

A: The text layer is different from the point, line, and region layers. The style is stored in the text object, so you need to perform two steps before modifying the text style: 1. Set the text layer editable; 2. Select the text object to be modified the style. You can either select one or select all the text objects, and then click the corresponding button in the text style group.

A: This effect can be achieved by setting the offset parameter of the advanced Settings in a UniqueTheme.

A: When you use the SymbolMarker.FromGeometry () method, the imported Rectangle2D parameter determines the symbol location. If the symbolBounds is set as the range of the whole symbol, then the geometry object scope (Bounds) will control the geometry objects position and scaling relation in the symbol. If you need to set the geometry object to fill the whole symbol, the symbolBounds can input the Bounds of geometry object.

A: The steps are as follows: 1. Please use the Map.ToXML method to get the map XML string; 2. Then use the Maps.Add method to add the map to the Maps. Notes: 1. XML string includes all map configuration information (map name, transparent , properties, layers, thematic map and so on). 2. Since the map depends on the workspace, you need to save the workspace before you exit the program.

A: Make the 3D shading map for the existing DEM data. And the vector data is overlaid with a certain degree of transparency.

A: Set the tracking layer to use antialiasing through the TrackingLayer.IsAntiali as property. After it set to antialiasing, you can remove the serrated to make t he display more beautiful.

A: You can modify the frequency in the water surface symbols to make the water wavier.

A: This is because the printed paper is less than the size of the layout paper. Solution: when printing, set the paper size and layout size the same at the page setting.
