I have opened a MFD 8-Map in EDGE 9.0.169.7.

This Map contains a "Surface" with Slope in percent.

Now i want to select all Pixels that are equal or higher than 30.

In MFD 8 i do that with SQL:

UPDATE [Surf_percent] SET [Selection (I) = TRUE

WHERE [Height (I)] >= 30;

How could i do that in MFD 9 ?

Thanks.

In 9 / Viewer, selection in images is currently limited to whole tiles.

What were you going to do with pixels with heights equal to or higher than 30 after selecting them? Depending on the operation, that might be doable using a bigger query or (more likely) using a combination of a query and a script.
