Glad you got it working Ares!

Getting spoiled with this freakin HD image. Might have to cry when my 7 days are up. Don't think I want to pay more for something else after already spending enough on other software.

It's nice, but doesn't touch GR3/2 yet.

To me I think it looks better than the GR smoothing, but it is lacking some features. I know it is only in beta right now, but if they added gps and some of the other stuff I would def use it.

Better than GR smoothing ?? Sorry, but I have to defend GR here... GR actually smooths, while RadarLab HD just smooths, then when you zoom in, blurs.

Ah I wasn't knocking GR or anything just a preference thing.

At least you don't have to upgrade your computer to use radarlab HD.It requires no additional hardware or software.Radarlab HD is awsome and it can only get better with time.The smoothing is great, I like everything about it.I would recommend it to anyone.

You don't need to upgrade your system because RadarLab does not have true smoothing like GR. Instead, when the image is sent to you in RadarLab, it is already smoothed. That's why it gets blurry the further in you zoom.

Now I'm not saying RadarLab HD is a bad software. I'm simply saying that if it wants to run with the big dogs, it has the potential, but needs to catch up in some ways.

What is true smoothing?And isn't level ll data the same as smoothing?

No, not at all.

See in GR3/2 (it doesn't matter which), the radar data is sent to you from the server, unsmoothed, and in its native Level3 or Level2 format (depending on which you are running). After GR3 displays it, you can then smooth it, and as you zoom in, it keeps the color lines clear cut, so you could go down to your street if you wanted to, and the line would still be sharp.

With RadarLab HD, the image is sent to you smoothed, so as you zoom in, the radar is doing nothing more than blowing up as if you zoomed into a picture you took on your computer. Eventually, it just gets blurry and useless.

Level2 data is different from level3 data. Here is the explanation from Aaron Wesson over on the StormLab forums:

Archive Level 1 - This is located at the RDA and it is the analog data of the receiver. This data consist of synchronization, calibration, date, time, antenna position and status of the radar. Level 1 data is mostly used for maintenance activities such as testing the signal processors.

Archive Level 2 - This is where the digital base data from the signal processor is archived. The digital base data are the reflectivity, velocity and spectrum width ouputs from the RDA. This archive level is by far the most important and useful becuase it allows total recreation of a wether scenario. This data can even be sent to the RPG for processing into products as though it was actually LIVE data. MOST research and development activity is accomplished using this data.

Archive Level 3 - At this level all products produced by the RPG can be saved. The MAJOR DIFFERENCE between Level 2 and Level 3 is that only products generated by the RPG can be saved (NOT DATA) So when you are looking at Level 3 data you are looking at a product that has ALREADY BEEN CREATED by the RPG.

Archive Level 4 - There is really no difference in Level 4 compared to Level 3 data. The only difference is the location that you can save the data from. Level 3 data is saved from the RPG. Level 4 data is RPG data but it is saved from the PUP (Principal User Processor) It is now called an OPUP in most places (Operational Principal User Processor) All PUPs and OPUPs have this ability.

Thanks Ares for the information I now understand everything about level ll and level lll data.
