After you calculate the volume measurements, export the data to a CSV file (there will be a button on the Feature Measurement Information screen to do this). After that, you can select the layer and use the Layer | JOIN Attribute Table/File to Layer function to add the attributes to the features.
Blue Marble Geographics will provide support before you buy a license. I suggest that you send them your question directly via e-mail (email@example.com). If you are trying to resolve a problem, be sure to include a detailed description of your work flow, and the data that you used. This will ensure a faster response.
What version of Global Mapper are you using?
Your EXPORT_VECTOR command is split across multiple lines, but you don't have the line continuation sequence at the end of the first two lines. I assume that this is just for the sake of making your post easier to read.
The LAYER_BOUNDS parameter will use the bounding rectangle of the layer, not the actual area feature(s) in the layer as the export bounds. If you are trying to clip your data to an area feature, you need to use the POLYGON_CROP_FILE parameter instead.
The format for the slope attribute can not be changed by the user at this time, nor can the slope percent be split out into a separate attribute by the Calculate Elev/Slope Statistics function. I have added feature request #22986 so we can evaluate adding additional formatting options in a future release of Global Mapper. We will post a message on this thread when the status of the request changes.
In the meantime, you can use the Attribute Calculator to split the slope percent into a separate attribute.
- Use the Digitizer to select the features you want to modify
- Right-click and choose Attribute Style Functions | Calculate/Copy Attributes for Feature Selection. The Attribute Calculation Setup dialog will be displayed.
- Use SLOPE_PCT (or another name of your choosing) for the new attribute to be added
- Select the Use Formula Calculation option
- In the formula field, paste clip(search(SLOPE,"\d*.\d*%"), "", "%"). (The formula searches the string for a number followed by a percent sign, then clips off the percent sign. See Global Mapper help for more information.)
