Geographical overlay

Open dvdesolve opened this issue 4 years ago • 2 comments

WXtoImg provides nice feature to overlay geo data such as coastlines, country borders, rivers, lakes etc. Also it allows to draw coordinate grid and base station location. Thus user can easily find himself on received image and picture becomes much more informative.

I have the full command syntax from the manual, but I am sure you have found it as well. Have you tried it with Meteor?

wxmap -T (time is seconds since EPOCH) -H weather.tle -p 0 -l 0 -o (time of pass start) "output_map.png"

This works for NOAA but I have not seen it used for METEOR. This adds the little +:

-L l/l/a Set ground station location using "latitude / longitude / altitude". Latitude and longitude are given in degrees and fractions of degrees, with north and east values given as positive numbers, and south and west values given as negative numbers. The altitude is given in meters above mean sea level. For example: -L"-36.85/174.81/30".

Thank you for info. But i think it depends on whether the image was rotated or not. What is the program used to generate output_map.png for further feeding into wxmap?
