Viewshed multiple points and attributes not working as expected
I'm currently testing GM 21 and the viewshed tool. I have loaded DEM files for my country and I'm using the viewshed to find blindspots for radars all over the country.
I can not get it to work as intended with selecting all radar sites in one and executing the tool.
I have set attributes for all sites for sensor elevation and radius, but the program won't aknowledge the altitude as above sea level.
I've tried the following versions of attributes:
TRANSMITTER_HEIGHT - 1234.0 ft
TRANSMITTER_HEIGHT - 1234.0 ft above sea level
OFFSETA - 1234.0 ft
OFFSETA - 1234.0 ft above sea level
OFFSETA_MSL - 1234.0 ft
OFFSETA_MSL - 1234.0 ft above sea level
No matter what I try it stills reverts to above ground when generating the viewsheds. And even though if I set the transmitter elevation to above sea level in the dialog it still doesn't change in the resulting viewsheds since there apparently already is a attribute present.
The reciever height turns out ok all over when setting it to XXX feet sea level in the dialog, as this is the same for all sites per viewshed, but all sensors have a different altitude above sea level based on their location.
So for now I'm stuck with creating the viewshed per sensor.
BTW, great to see the speed highly improved from previous versions.
