Frank's dashboard

Lets start by examining a fixed point:
To use buildings as analytical constraints, you need to represent them in STK as either terrain data (used in creating Azimuth Elevation mask constraints) or as 3-D models (used to create Body masks which are very similar to AzEl masks and can be used as line of sight constraints as well)

Lets look at the terrain solution first:

You need to get the building height information into a supported terrain format. DEM's are one way, there are others listed in the docs. Typically the source of this data is either LIDAR, or dimensional blueprints (vector data) converted to a raster Lat/Lon/Alt data set.

I should caution that typically these are very dense data files, which tends to make them rather large, and somewhat of a memory hog if not managed properly. Remember that this is height data for buildings instead of natural terrain, and flat surfaces like rooftops and building sides cause more unusual issues than you would expect.

Load in the terrain data into the scenario, assign a facility/target object to use terrain for it's altitude, and then save the scenario. Close the scenario.

Hand edit the *.f (or *.t) file in a text editor to change the NumAzRaysInMask value from 360 to something much larger. This number represents the number of terrain data samples performed in 360 degrees. Normally this number defaults to the equivalent of 1 degree separation between samples. To increase the detail of the AzEl mask, increase this number. To figure out the equivalent angular resolution, divide it by 360 and you're left with the number of degrees between each ray used to create the masking file.

Save the file. Re-load the scenario, and then tell the facility to use terrain to calculate the AzEl mask. This may take a while depending on the number of points it has to sample.

Save the scenario. This saves off the .aem file for the facility in question so it doesn't need to recalculate the data.

Turn on the use of AzEl masks as a constraint for the facility. You can then expect the ACCESS tool to do it's thing, which may take some time depending on how detailed an AzEl mask file was used.

As a side note: I recommend removing the terrain data from the scenario as it's likely a memory hog due to the number of points needed to represent the detail of buildings. If everything is static, you won't need it again unless you re-position the facility. Even if other things are moving around, like aircraft, satellites, etc... the analysis from the fixed point doesn't change the masking effects of the building. It's whole world of what's visible and what's not, due to buildings, is represented in the *.aem file.

next post: we'll look at using 3-D models of buildings as a source of analytic line of sight obstruction, and later, address the RF questions w/ TIREM

Ok, So I'm replying to myself, but I had to get the party started by seeding a question or two.

It hasn't worked for me since October last year, and none of the method people has suggested worked for me (ie. re-adding the app, re-enter the information, adjusting the settings, etc.).

What I find it very vexing is the fact that the application page on facebook has been long ignored by the developers at the same time last year when the application was first broken. It's one matter that they couldn't figure out what's wrong with it, it's another matter to ignore their user base completely. I would have appreciated (and more willing to give more time to the developers) if they would have at least informed us that they have been listening and still trying to work out the problem. However, that hasn't happen and I am fed-up on this kind of treatment thus far.

You're right, I've done the same now. – rhino75, on May 07, 2008 15:21

For the last several days, clicking on the Twitter app in Facebook yields a page headed thus:

RFacebook environment information

This shows you at a glance the information that RFacebook has populated for you.
More information at rfacebook.rubyforge.org. Please report RFacebook bugs here.

Until yesterday, updates through the Web or IM were relayed to Facebook quickly. It now appears to be spotty at best.

I justed deleted this application and uploaded "TwitterSync" instead, which is all I really wanted the program to do.

Same problem here. Occurs when I enter my Twitter login information after adding the App.

same as the rest of the gys here

same as mjsmith1223

Twitter Facebook app is busted again. Same problem and output as antoineclarke.

It wasn't worked for a couple of days and no news, which is annoying. It means I have no idea if anyone realizes there is a problem or not. Which is a poor start. In case it helps I've cut and pasted what comes up on the screen:

I am still having the "Environment Information" problem.. It's the only thing that appears when I try to use Twitter on Facebook.

Works for me. Great fix Alex !!

Hey, My Twitter Facebook AP is working now!! WOO HOO

It works for me now! Thanks Alex.

Just tried re-installing it. Still getting the compile errors.

i wish you luck in fixing it!
