latitude-longitude

I have the following SELECT statement to calculate RADIANS and COS . SELECT COS(RADIANS(latitude)) as Lat FROM tbl_geometry; But I'm getting an error: Error converting data type varchar to float. My attempts: Attempt #1 : select Cos(convert(float, (Radians(convert(float, latitude))))) as Lat from tbl_geometry; Attempt #2 . select Cos(Radians(convert(float, latitude))) as Lat from tbl_geometry; Both attempts result in the same error. Note : column Latitude is of type varchar . Use try_convert() to find the invalid data: select latitude from tbl_geometry where try_convert(float, latitude) is

This question already has an answer here: find locations within certain lat/lon distance in r 4 answers Given a data frame with latitudes and longitudes I want to add a column that simply contains the count of other points (of the same data frame) that are within a certain radius e.g. within 10 km of that specific point. Example data: set.seed(1) radius<-10 lat<-runif(10,-90,90) long<-runif(10,-180,180) id<-1:10 dat<-cbind(id,lat,long) id lat long [1,] 1 -42.20844 -105.8491530 [2,] 2 -23.01770 -116.4395691 [3,] 3 13.11361 67.3282248 [4,] 4 73.47740 -41.7226614 [5,] 5 -53.69725 97.1429112 [6,]

I'm trying to capture tweets using twitter4j's streaming methods from the area of Hongkong. However not matter what latitude or longitude coordinates I choose to do so (from http://www.latlong.net/convert-address-to-lat-long.html ) I always get invalid latitude/longitude error. Latitude/longitude are not valid: 22.27, 114.17, 22.35, 114.21 The code I use is otherwise working fine: TwitterStream twitterStream = new TwitterStreamFactory(cb.build()).getInstance(); FilterQuery fq = new FilterQuery(); fq.locations( new double[][]{ new double[]{ 22.274286d, 114.166875d}, new double[]{22.351943d, 114

Link to workbook on public tableau I created calculated value to determine grade for business, and this is colormap (in tab Grade per Location ) And when I hover over datapoints on map (tab Map ), it displays correct Grade, i.e. D for Shish Boom Bah Car Wash But as soon as I select any location from a drop-down, all grades are A Tot_Avg is calculated like this: { EXCLUDE [Location (Loc)] : AVG([Rating]) } Avg_Rating like this: AVG([Rating]) And here are the conditions for receiving an A: IF [Avg_Rating] > ATTR([Tot_Avg]) - (.10 * ATTR([Tot_Avg])) THEN "A" How to troubleshoot? I think your

I have been trying to get speed by the help of GPS. I would like to get Gps datas(latitude-longitude-speed) when my telephone fell down. When telephone fell down, gps datas are obtained and sent to my server. For this aim, I used threads. Each thread get gps datas and send to server them. My problem is speed value. I got speed calculating distance between two location and time (speed = distance / time) Thread makes : @Override public void run() { Looper.prepare(); float distance = 0.0f; float[] results = new float[1]; Long longValue = new Long(11); double firstLatitude; double firstLongitude;
