altitude

I am new to PyEphem and I am trying to figure out what it can do and how it works. As I do not want to use it as a black box and blindly trust whatever figure I get, I wanted to recreate an example that is explained here . The example calculates the azimuth and altitude of an object for a given observer on the 10th August 1998 at 23:10 UT. The following parameters are given: RA = 16 h 41.7 min, DEC = 36 d 28 min The observer's latitude is 52 d 30 min North and longitude 1 d 55 min West. The correct answer according to the example (which I can recreate in Excel) is AZ = 269.14634 degrees and

I have application using Android 2.1 which utilize LocationManager to get the altitude. But now, I need to obtain the altitude using SensorManager which requires API Level 9 (2.3). How can I put the SensorManager.getAltitude(float, float) in my 2.1 android application by putting a condition and calling it by a function name (possible in normal Java)? Thank you in advance UPDATE 1 If you have noticed that my application need to be compiled using Android 2.1. That's why I'm looking for a way to call the function by name or in any other way that can be compiled. You can call the method using

I have a problem in getting the altitude , it returns 0.0000 . Here is my code: - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { NSString *tAltitude = [NSString stringWithFormat:@"%f", [newLocation altitude]]; CLLocationCoordinate2D coord=newLocation.coordinate; MKCoordinateSpan span = {.latitudeDelta = 0.005, .longitudeDelta = 0.005}; MKCoordinateRegion region = {coord, span}; [map setRegion:region]; NSLog(@"Location: %@", [newLocation description]); NSLog(@"altitudine:%@",tAltitude); } If you are

Does anyone know if there is a tool in R to find the height above sea level of a location, given the latitude and longitude ? Or you can use the package that looks up from geonames, and get the value from the srtm3 digital elevation model: > require(geonames) > GNsrtm3(54.481084,-3.220625) srtm3 lng lat 1 797 -3.220625 54.48108 or the gtopo30 model: > GNgtopo30(54.481084,-3.220625) gtopo30 lng lat 1 520 -3.220625 54.48108 geonames is on CRAN so install.packages("geonames") will get it. The difference between these two models is because they are only approximations based on satellite data. Don

What are the data needed for calculating barometric altitude? How do I get them and then calculate the altitude? Also how accurate is the barometric compared to GPS altitude? I tried GPS but after searching hours in the web I cannot find a suitable Geoid library. Please correct me if I got any concept long. You need to use the pressure sensor to measure the pressure then use the SensorManager.getAltitude(float, float) call to convert the measures pressure along with a reference sea level pressure to get the altitude. The tricky bit is what to use as the reference pressure. This will change

I've been having trouble finding a way to get the altitude of the device. Could someone give me a pointer or put together a short script that gets the altitude of the device and prints it? Only in swift. Thanks!
