Raster Query Settings

Feature Description

When querying raster values at the mouse position, you can configure whether search results display raster information and slope/aspect values, along with parameters like elevation scaling factor.

Steps

In the "Spatial Analysis" Tab's "Raster Analysis" group, click the "Raster Query" drop-down button and select "Raster Query Settings" to open the "Grid Query Parameter Settings" dialog.
Display Raster Information: Check this box to show grid row, column, and raster value information of the selected cell in search results. Uncheck to hide raster information.
Display Slope and Aspect: Check this box to display slope/aspect values of the selected cell in search results. Uncheck to hide these values.
Elevation Scaling Factor: Required when elevation unit differs from x/y coordinate units. Multiply elevation values by this factor to align units. Example: For x/y in meters and z in feet (1 foot = 0.3048 meters), use 0.3048. Value 1 indicates no scaling.
Recommended for data with projected coordinate systems (units: meters). For geographic coordinate systems, specify appropriate z-factors at corresponding latitudes. Use the following z-factors when x/y units are degrees and z unit is meters:
```
   Latitude     Z-factor
       0         0.00000898
      10         0.00000912
      20         0.00000956
      30         0.00001036
      40         0.00001171
      50         0.00001395
      60         0.00001792
      70         0.00002619
      80         0.00005156
      
```
Click OK to complete raster value query configuration.
