westphae / geomag Goto Github PK

So sorry to open an issue for this, but you don't have discussions enabled. Could you please let me know where you found your WMM2020_TEST_VALUES.txt data? I am writing my own version of this, and can only find the WMM2020testvalues.pdf file that came with the Legacy C app.

Hi, pkg.go.dev maintainer here. This is a response to your anonymous feedback from February 8. Apologies for the delay.

We get all our module information from the proxy (proxy.golang.org). So whenever you or anyone else go gets a version of your module through the proxy (which is the default setting for go get), then we'll soon see it and process it.

So if you just run go get github.com/westphae/[email protected], it should show up on pkg.go.dev shortly.

We're working on a better system, where you can click a button on the site to fetch a new version.

func GetGEOID(lat, lng float64) (float64, error) {
	//in order to use package, has to move
	loc := egm96.NewLocationGeodetic(lat, math.Mod(lng+360, 360), 0)
	h, err := loc.HeightAboveMSL()
	if err != nil {
		return 0, err
	}
	geoid := -h
	return geoid, nil
}

func MSLAltToW84Alt(lat, lng, msl_height float64) (float64, error) {
	geoid, err := GetGEOID(lat, lng)
	if err != nil {
		return 0, err
	}
	return msl_height + geoid, nil
}

==================

Currently the error model is hard-coded in the wmm package. It depends on the cof file, so really should be an asset.

Hello, i am begginer in Go and someone can tell me how i install this repo? please

Hi, I am very new to gis, but if I have lat, long, and a geometric altitude (above mean sea level), can I use this package to convert the geometric altitude to the wgs84 altitude or egm96 altitude?

lat, lng := 39.865315, -121.32870643118366
loc := egm96.NewLocationGeodetic(lat, lng, 0)
h, err := loc.HeightAboveMSL()
if err != nil {
log.Panicln("err", err)
}

however, I got:

2023/02/22 09:53:41 err requested longitude -121.33 lies outside of EGM96 longitude range  0.0 to 360.0
panic: err requested longitude -121.33 lies outside of EGM96 longitude range  0.0 to 360.0
