Questions About Grlevelx Products

Seems there should be a FAQ that includes all this info, but I couldn't find it and digging around the Trial Forums is scattered. I have some basic questions here about these products as a friend and I are considering purchasing.

1) Does GRlevel3 only work with level3 data?
a) I understand that is free NWS or a paid Allisonhouse source right?
2) What all does Grlevel2 support? Will it work with live level2 data as well as archive level2 data? Will it still work with level3 data?
3) What are the feature differences between Grlevel2 / 3? Does GR2 not have radar attribute table information and icons for hail, meso, tvs, etc? What other differences?
4) What about the analyst version - is it like 2 or 3 mostly? What data will it work with (level 2, 3, or both)? Does it support attribute table stuff?
5) Any other obvious differences you care to add...

Thanks

1) Does GRlevel3 only work with level3 data?

Yes..thus the "3" at the end
a) I understand that is free NWS or a paid Allisonhouse source right?
yes
2) What all does Grlevel2 support?

Level 2 data
Will it work with live level2 data as well as archive level2 data?
Yes
Will it still work with level3 data?
No...thus the "2" at the end
3) What are the feature differences between Grlevel2 / 3?

GRlevel2 is for level 2 data...Grlevel3 is for level 3 data. The difference is primarily the difference between level 2 data and level 3 data...and the lack of GPS support in GR2.

Does GR2 not have radar attribute table information and icons for hail, meso, tvs, etc? What other differences?
Level 2 data doesn't have that information so no..it doesn't have it.

4) What about the analyst version - is it like 2 or 3 mostly?
GRLevel2 Analyst Edition is for level 2 data
What data will it work with (level 2, 3, or both)?
Level 2
Does it support attribute table stuff?
No..see above about level 2 data.
 
Ok, thanks Tyler. It sounds like you thought some of those were kind of stupid questions, but I and others were thinking that Grlevel2 was a superset of Grlevel3 in the sense that it would do what Grlevel3 does plus it will handle level 2 data. That's why the confusion.

We were thinking level 2 data in the field might be nice, but sounds like Grlevel2 isn't really the product for chasing as no attributes and no gps. Plus I suppose the level2 data files are quite a bit larger.

So to be covered properly for chasing and level2 archives / live data it seems both products would be required.
 
99% of chasers will use GR3...many of us with GR2 wish it had GPS then we could use it..but it doesn't

If it were me...I'd buy GR3 and GR2AE as GR2AE has the 3D cool stuff :)

As for file size, you're talking 100-200KB vs. 3-4MB. Unless you chase in EVDO Rev. A coverage, you'll probably want GR3. I chased a couple times last year with level3 data and while it was nice, it was a pain as any signal blip would start you into needing another download.

Where do you all get your road shapefiles? I have been tediously downloading county after county of road data from the arcdata TIGER 2000 site. But there have been wholesale changes in roads and even an interstate quality highway that have been built in my area that are not represented in the data. The assumption is that all over this type of thing has occurred, so I have absolutely no trust in the road data as presented from the arcdata site, for places in which I may be chasing. Can I get current road data from somewhere, that is able to be imported into GRL3? Thanks.

I have downloaded level 3 radar archives and am curious how to view them on GRLevel3?

Also, does GRLevel3 auto-archive radars? EDIT - Skip this one, I see the button now...
 
I read a posting in another thread in which someone--I forget who--wrote of running both GRLevel3 and StormLab. I use GRL3 and I'm wondering why one would use both programs. Aren't the features pretty much the same?

That was me who wrote that. There are differences in the programs; for instance, its easier to navigate through multiple radar sites in StormLab (multiple windows at once). StormLab, which at the time, had easier archiving controls and did a better job updating radar images to my website. Basically, I ran that one in the background unless I wanted to see multiple sites if a storm was between radars.
 
Here's a tip for GRLevel3....
You can run more than one instance of it. Hence, you can view more than one radar site at once! When you have one open to your radar site, simply open another one and select your second radar site and so on.

Beware though, GRLevel3 uses quite a bit of memory. I have a full Gig of memory on mine and don't run into many issues. Also my video card is not the standard "on the mobo' card. That helps a lot.

GRLevel3 ingests the raw data files and does all the calculations to create the image you see on screen. That's part of the reason it uses up some CPU time and some memory. It also loads all those GIS files, backgrounds, etc. into memory as well, so even more memory gets chewed up.

As far as the differences between Level II and III data? I tend to look at it this way. I'm using GRLevel3 to help get me in close to the storm and position myself for the best view or best location to report it. Level III information is perfectly adequate to do this. I'm not there to analyze the storm. That's for the scientists of the group to do. I'm there to Observe, Record and Report. I don't really need to know what the storm is doing at all levels and try to inspect it. I want to watch the storm, not the radar screen!

Yes, I want to know where the couplet it. Yes, I want to know the VIL so I can avoid the hail core I certainly want to know where the hook is, so I can avoid that and get to watch it rather than be part of the debris showing up as a high Dbz level. L III is more than enough to get me where I need to be. I can also tell with the available mesonet data, what happening in locations near me. If I need a second opinion, I fire up another instance of the program and look from another angle (radar site). All in all, it works out pretty well.

I would examine why I wanted L II data and what I am really going to use it for. Same conditions apply with Mobile Mesonet set ups, Lightbars, Radios, etc. (ad nauseum!). Take a look at your uses for it. Is it really going to help you any more than what your using now? No need to answer me on this one. I certaibnly don't want to hijack the thread or start yet anotehr flame war, Just simply ask yourself, "What am I going to do with this information? Is it really going to help me find and photograph the once ina lifetime Supercell?". It's really as simple as that. ;)
 
A TAR file is a compressed archive, like a ZIP file. You must extract it first. WinRAR, shareware available from www.download.com, can extract this type of archive. You can then drag and drop the extracted files into GRLevel3. Although I believe it will only render about 20 scans at a time?

What a great idea! Thanks! The thought never occurred to me and probably never would have, though now that you mention it, it's so commonsense.:)

John,

That's the tip of the week--thanks.
 
Registration question.

I already own GRLevel3 wanting to buy GRLevel2 yet before purchasing I am wanting to be able to use it on both my home and work computers.. Am I able to use the same registration key if software is installed on both computers? Or would I have to buy the program twice??? Much Thanks!!
 
I use the same registration key for GRL3 on both my home pc, and my laptop. The software will allow it, and what I've read on the GR forum says this is allowed. As far as your work computer goes you may want to check the forum for rules on that. Hope this helps, and someone please correct me if I'm wrong. :)
 
I think the license states that you CAN install it on two computers as long as you are only using ONE at any given time.
 
The license allows for "INSTALLATION ON (1) PERSONAL DESKTOP AND (1) PERSONAL LAPTOP".

So short answer, you can have it on the PC at home (I have 4 monitors at once, GR3 rules!) and on my laptop.

For you Mac users, download Parallels to run GRX.

Jeff is correct. This issue came up 18 months ago and I emailed Mike Gibson and he came over to the forum and posted this response:

http://www.stormtrack.org/forum/showpost.php?p=206211&postcount=16

I could swear he emailed a copy of the EULA to me that same day. Give me some time and I'll boot up my PC and see if I have it. Otherwise I don't think it installs to the Windows directory any longer from the exchanges I had with Mike that day.

I recently bought GR2AE and thought I read what Jeff mentioned and that is that you can't run both copies at the same time, so let me find that EULA and it will definitely clear it up.
 
GRLX EULA

Jeff - For some reason I am thinking the part about not using both computers at the same time is a data subscription restriction (i.e. Allison House) versus a GRLevelX thing. Now I need to look at the TOS for my AH subscription as I know I read that somewhere.

EDIT: The one machine at a time thing is an AH policy per "Subscription Usage" on their website:


http://www.allisonhouse.com/acceptable_use.php

I pulled the e-mail and am putting the EULA text into this message:

Awesome! Thanks for all the quick responses.. I am going to purchase GR2 for the house and just let work purchase GR2 for the work comp since I work for the state doing EM/Forecasting duties.... Much appreciated!!
 
Remember too, since you already own the lic. for level-3 you can multiply the usage if you only use a dedicated computer for each version. I have four systems that run GR...two running GR2AE two running GR3. I only use GR3 for chasing, and AE at home.

I'm glad Mark mentioned AH, I was going to put it on all the GR enabled computers which would mean technically the one AE home computer (which is monitored sometimes when I'm on the road) would technically be another person. Guess they'll just have to deal with the default data, not spending more AH since I'm still only working short term non-secure jobs.
