Re: [Xastir] WMSRadar and net acquired .gif

Mon, 10 Mar 2008 05:00:40 -0700

Attached is a .geo file I created for the Iowa State radar composite. This seems to work better for me. 

Gerry, if you want some help, send me the info off list.

I do the radar mosaic and something's definately off with that. I've been troubleshooting but I don't have an answer. 

I'll try a new approach tomorrow or Tuesday for this.
Send me your appropriate RIDGE .geo for MAF. I'll compare it to what I have and see if we can get it better...
Also: Why N0Z? I prefer N0R for base reflectivity (from a sorta professional view).
Anyone want to work with me to make individual Level II sites available? I haven't time to script up the .geo's but can provide the data on site image dimensions...

I need some help. I am new to Linux and Xastir both so please keep things simple for me.
I noticed today that the radar that I load from the website www.srh.noaa.gov/ridge/RadarImg/NOZ/MAF_NOZ_0.gif is off by several miles. I am talking in the neighborhood of 50-75 miles. When I adjust the size of the .gif the center of the radar (the ground clutter) moves around as I change the size. I had the ground clutter centered but the edge of a recent storm was real far off. So I tried the WMSRadar on my Xastir and discovered that the image is indeed better but it shows the storms about 120 miles north of their actual location.
What setting(s) do I have wrong? The purpose of this set-up is to serve as a remote station for Skywarn operations if something happens at the NWS so I need the radar to be as accurate as possible.
Oh the technical stuff-- Ubuntu 6.06 and Xastir 1.71. I am not much of a programmer so this is all real close to OEM specs. 

Thank you for your help,
