WEBVTT 00:00:00.120 --> 00:00:02.000 Hello, I'm Jeff Jalbrzikowski. 00:00:02.360 --> 00:00:06.230 In this video we will review session solutions which are 00:00:06.300 --> 00:00:09.960 the results from session processing in OPUS Projects. 00:00:11.640 --> 00:00:14.280 Please note the current version of OPUS Projects may look 00:00:14.330 --> 00:00:16.280 slightly different than what we show here. 00:00:16.760 --> 00:00:19.000 Its functionality generally remains the same. 00:00:20.720 --> 00:00:24.980 Before we get started analysing our session solutions, some of 00:00:25.040 --> 00:00:28.200 you might be asking yourself, how do I know if 00:00:28.270 --> 00:00:29.440 I have solutions? 00:00:30.040 --> 00:00:32.850 Maybe you've been following along with our training videos, you 00:00:32.900 --> 00:00:34.240 took a break, you're not sure. 00:00:34.920 --> 00:00:37.900 So let's jump into our training project and take a 00:00:37.970 --> 00:00:40.710 look at these few ways listed on the screen to 00:00:40.770 --> 00:00:43.040 see that we do have session solutions. 00:00:43.800 --> 00:00:46.650 All right, so if if you've opened your training project 00:00:46.700 --> 00:00:49.130 to the managers page and you see the blue lines 00:00:49.180 --> 00:00:51.670 in the map like mine, then you have some session 00:00:51.720 --> 00:00:53.120 solutions ready to analyse. 00:00:55.360 --> 00:00:58.320 So a few things to look at right here above 00:00:58.390 --> 00:01:00.520 the map in this drop down menu. 00:01:00.600 --> 00:01:03.420 Now you're able to choose between OPUS results, which is 00:01:03.470 --> 00:01:06.400 the initial default, and all sessions, which is what we're 00:01:06.440 --> 00:01:07.000 looking at. 00:01:07.000 --> 00:01:07.400 Now. 00:01:09.000 --> 00:01:12.390 If we go ahead to the map and click our 00:01:12.480 --> 00:01:17.170 Zoom to CORS button, we'll see all the blue baselines 00:01:17.260 --> 00:01:18.040 drawn in. 00:01:21.640 --> 00:01:24.190 Now if we scroll down below the map in our 00:01:24.250 --> 00:01:27.890 Marks and Sessions table, notice that we have these matching 00:01:27.950 --> 00:01:30.560 blue lines from the map that are now in all 00:01:30.620 --> 00:01:31.959 of our column headers. 00:01:32.720 --> 00:01:35.980 So a blue line in the session column indicates the 00:01:36.040 --> 00:01:37.480 solution is available. 00:01:39.040 --> 00:01:41.400 If we look at this example, I'll fade in over 00:01:41.450 --> 00:01:42.920 here on the right hand side. 00:01:42.920 --> 00:01:46.459 This is the same Marks and Sessions table from the 00:01:46.530 --> 00:01:50.220 same training project, but just before we ran all of 00:01:50.290 --> 00:01:51.920 our session processing. 00:01:54.080 --> 00:01:57.520 Now, where are these session solutions? 00:01:57.520 --> 00:02:00.160 Where do we go to review our results? 00:02:01.440 --> 00:02:04.190 We're going to use the Show file window to review 00:02:04.240 --> 00:02:05.480 our session solutions. 00:02:06.760 --> 00:02:09.370 So to to open that, we're going to scroll up 00:02:09.430 --> 00:02:12.090 here to the top of the managers page and over 00:02:12.150 --> 00:02:14.639 here under our controls, we see Show file. 00:02:15.560 --> 00:02:16.560 So we'll click that. 00:02:18.200 --> 00:02:20.560 OK, we have our Show file window open. 00:02:21.440 --> 00:02:23.320 There's a few things that you probably noticed. 00:02:23.320 --> 00:02:26.540 First, we see the drop down menus at the top 00:02:26.610 --> 00:02:28.440 in the gray toolbar area. 00:02:29.200 --> 00:02:32.480 See, there's three of them next to the drop down 00:02:32.550 --> 00:02:35.830 menus. You see right now it's grayed out the Show 00:02:35.900 --> 00:02:36.720 file button. 00:02:37.240 --> 00:02:40.230 It's important to remember that every time you choose a 00:02:40.280 --> 00:02:43.210 different item from one of the drop down menus, you've 00:02:43.270 --> 00:02:46.090 got to click that Show file button to actually apply 00:02:46.139 --> 00:02:46.960 your selection. 00:02:48.040 --> 00:02:51.110 If we open the drop down menu for the middle 00:02:51.180 --> 00:02:55.080 box, we can see the list of session solutions available. 00:02:56.639 --> 00:02:59.889 We check the drop down menu of the right side 00:02:59.960 --> 00:03:03.360 box, we see the list of reports or results that 00:03:03.440 --> 00:03:06.400 are all included in the session solution. 00:03:08.600 --> 00:03:11.940 So let's leave everything as it is now, and we'll 00:03:12.010 --> 00:03:15.430 go over the main items that our personnel look for 00:03:15.500 --> 00:03:18.160 if your data is being submitted to NGS. 00:03:19.680 --> 00:03:22.389 First, we take a look at the standard error of 00:03:22.450 --> 00:03:23.160 unit weight. 00:03:24.480 --> 00:03:27.520 In this solution, it's 0.773. 00:03:28.880 --> 00:03:36.080 Acceptable values are anywhere between 0.1 up to about 1.1. 00:03:37.400 --> 00:03:40.330 For more information on that statistic, take a look at 00:03:40.380 --> 00:03:41.360 the OP User Guide. 00:03:43.000 --> 00:03:45.240 Next thing is just a couple rows below that, you 00:03:45.280 --> 00:03:46.680 see the total number of marks. 00:03:46.680 --> 00:03:48.730 Here we have 14, and we just are kind of 00:03:48.780 --> 00:03:51.250 looking for a check to know that Yep, that's the 00:03:51.300 --> 00:03:53.920 number of marks we expected to be in this solution. 00:03:55.600 --> 00:03:58.730 Next we go a few more rows down to our 00:03:58.810 --> 00:03:59.800 overall RMS. 00:04:00.680 --> 00:04:04.400 What we're looking for is less than or equal to 00:04:04.480 --> 00:04:04.800 2 centimeters. 00:04:05.560 --> 00:04:07.240 So here we have 1.6. 00:04:07.880 --> 00:04:08.520 Looks good. 00:04:09.680 --> 00:04:10.040 Next. 00:04:10.040 --> 00:04:13.960 Now we're going to scroll down inside the Show file 00:04:14.040 --> 00:04:17.960 window, so we're going to grab the scroll bar here. 00:04:19.200 --> 00:04:24.740 We're going to move down to our estimated to a 00:04:24.870 --> 00:04:27.880 priori coordinate shifts. 00:04:29.680 --> 00:04:33.100 What we're looking for is less than or equal to 00:04:33.180 --> 00:04:37.110 2cm horizontal and less than or equal to 00:04:37.180 --> 00:04:37.839 4cm vertical. 00:04:39.360 --> 00:04:42.440 So if we look at that table of the estimated 00:04:42.510 --> 00:04:46.570 a priori coordinate shifts, we see there's more than three 00:04:46.640 --> 00:04:47.200 columns. 00:04:48.720 --> 00:04:53.529 So here I'll highlight your northings are here, your eastings 00:04:53.610 --> 00:04:57.950 are here, and the heights, the ellipsoid height in this 00:04:58.029 --> 00:05:01.900 case, I know it's a capital H, but this indicates 00:05:01.980 --> 00:05:03.320 ellipsoid height. 00:05:04.120 --> 00:05:04.839 Those are here. 00:05:07.440 --> 00:05:10.820 These other three columns where each number is in the 00:05:10.880 --> 00:05:15.089 parentheses, Those are the uncertainties of the shift that they're 00:05:15.150 --> 00:05:15.920 paired with. 00:05:17.360 --> 00:05:21.350 Remember again, we're looking for 2cm or less horizontal and 00:05:21.420 --> 00:05:26.080 4cm or less vertical estimated a priori coordinate shifts. 00:05:26.680 --> 00:05:31.990 So if we look at our horizontal, our highest value 00:05:32.089 --> 00:05:34.960 is here at 1.1 centimeters. 00:05:36.600 --> 00:05:37.120 Looks good. 00:05:38.360 --> 00:05:42.720 And if we look over here at the vertical, our 00:05:42.820 --> 00:05:46.800 largest shift is here at 3.8 centimeters. 00:05:48.800 --> 00:05:52.640 So now we're going to use our middle drop down 00:05:52.720 --> 00:05:55.480 menu to move over to session 41B. 00:05:55.720 --> 00:05:58.790 Remember, we need to click the Show file button to 00:05:58.850 --> 00:06:02.170 actually see our results in the window, and there they 00:06:02.230 --> 00:06:02.480 are. 00:06:03.520 --> 00:06:07.480 So now we see we're looking at Session 202141 bravo. 00:06:08.560 --> 00:06:12.140 We see our standard error of unit weight here looks 00:06:12.210 --> 00:06:12.560 good. 00:06:14.600 --> 00:06:20.040 We see our total number of marks, 9 looks good 00:06:20.150 --> 00:06:22.279 overall RMS 1.4cm. 00:06:22.520 --> 00:06:24.740 That's less than or equal to the two we're looking 00:06:24.779 --> 00:06:24.960 for. 00:06:24.960 --> 00:06:29.960 If we scroll on down to our estimated upper coordinate 00:06:30.060 --> 00:06:35.620 shifts, remember again, we're looking for less than or equal 00:06:35.710 --> 00:06:40.710 to 2cm horizontal, less than or equal to 00:06:40.810 --> 00:06:41.640 4cm vertical. 00:06:42.640 --> 00:06:45.100 And we've met that here with a little bit better 00:06:45.160 --> 00:06:47.160 results than the last session solution. 00:06:47.640 --> 00:06:50.740 So at this point, we move on to the next 00:06:50.820 --> 00:06:53.920 session solution and so on and so forth. 00:06:54.320 --> 00:06:57.500 We want to examine the same statistics for each session 00:06:57.560 --> 00:07:00.680 solution before we move on to our network adjustments. 00:07:01.480 --> 00:07:04.370 Below the coordinate shifts table is a list of coordinates 00:07:04.420 --> 00:07:05.120 for each mark. 00:07:05.920 --> 00:07:09.600 There's also plenty more information in the other solution files, 00:07:09.660 --> 00:07:12.840 which you will need to investigate if your statistics do 00:07:12.890 --> 00:07:15.160 not meet the preferences we've reviewed. 00:07:16.040 --> 00:07:18.500 Here we are with the four main items to look 00:07:18.560 --> 00:07:20.960 for in your session solutions on one slide. 00:07:22.400 --> 00:07:24.950 So we use the Show file window to look at 00:07:25.020 --> 00:07:28.880 our solution statistics and we covered what NGS personnel will 00:07:28.940 --> 00:07:31.120 look for if your data is submitted. 00:07:31.680 --> 00:07:34.020 But now we'll take the rest of the video to 00:07:34.070 --> 00:07:37.110 demonstrate where else you can see the results from your 00:07:37.170 --> 00:07:38.200 session processing. 00:07:39.520 --> 00:07:41.600 Here we are back on our managers page. 00:07:42.560 --> 00:07:44.880 Let's move down to the Marks and Sessions table. 00:07:46.680 --> 00:07:50.040 So remember that our Marks and Sessions table is dynamic. 00:07:50.800 --> 00:07:53.510 If we go to our left hand drop down menu, 00:07:53.570 --> 00:07:56.150 we click and go all the way down to the 00:07:56.220 --> 00:07:57.800 last option, statistics. 00:07:58.800 --> 00:08:03.880 We see the Statistics table and it provides some additional 00:08:03.970 --> 00:08:06.640 statistics that we can analyze. 00:08:07.880 --> 00:08:11.900 We'd want to see high values for our percentage of 00:08:11.980 --> 00:08:16.560 observations used in our percentage of fixed ambiguities. 00:08:17.240 --> 00:08:21.740 But just like in our OPA solutions for our peak 00:08:21.840 --> 00:08:25.100 to peaks or P to P, we want to see 00:08:25.190 --> 00:08:26.440 small values. 00:08:27.000 --> 00:08:30.000 At this point, I'd like you to note that the 00:08:30.070 --> 00:08:32.590 P to P or peak to peak columns are in 00:08:32.660 --> 00:08:33.480 centimeters. 00:08:33.679 --> 00:08:38.470 Most of our units in most of the different areas 00:08:38.570 --> 00:08:43.650 in OP are in meters, but this table summarizes your 00:08:43.750 --> 00:08:48.240 NE and up peak to peak values in centimeters. 00:08:50.120 --> 00:08:54.200 I'd like to highlight that these peaks in the solution 00:08:54.270 --> 00:08:58.800 statistics table are the whole of all the observations among 00:08:58.870 --> 00:09:02.120 all the sessions for that row or that mark. 00:09:03.080 --> 00:09:06.870 These are completely separate from the initial OPA static peak 00:09:06.929 --> 00:09:07.480 to peaks. 00:09:08.320 --> 00:09:12.640 So let's visit the Marks page for Mark BRMR, or 00:09:12.740 --> 00:09:17.790 Bread Maker, by clicking the hyperlink right here in our 00:09:17.890 --> 00:09:20.280 solution statistics table. 00:09:22.880 --> 00:09:25.700 Here we are on the Marks page for BRMR, so 00:09:25.770 --> 00:09:29.000 let's scroll down below the description summary. 00:09:29.720 --> 00:09:33.900 Below the occupations there's a few things we could look 00:09:33.980 --> 00:09:34.200 at. 00:09:36.640 --> 00:09:40.980 The drop down menu here lets you change the coordinate 00:09:41.059 --> 00:09:45.309 source table to see the results from any sessions you 00:09:45.400 --> 00:09:46.600 have processed. 00:09:49.200 --> 00:09:53.840 Below the Processing results coordinate table we have processing plots. 00:09:55.280 --> 00:09:59.790 Note these are toggles that you can toggle on and 00:09:59.890 --> 00:10:05.600 off the different items available, such as the published which 00:10:05.690 --> 00:10:09.840 shows up as the large black line off back on. 00:10:10.880 --> 00:10:14.530 I'll point out that our session solutions show up here 00:10:14.600 --> 00:10:16.559 with the blue diamond symbol. 00:10:18.480 --> 00:10:22.220 Now if we scroll all the way down, we get 00:10:22.309 --> 00:10:27.700 to our processing results table, which has the same toggles 00:10:27.790 --> 00:10:33.910 above the table and individual statistics for the session solutions 00:10:34.000 --> 00:10:35.280 at the bottom. 00:10:38.200 --> 00:10:41.110 I have one more place to look at session solutions 00:10:41.170 --> 00:10:43.730 that I'd like to show you in this video from 00:10:43.790 --> 00:10:44.840 our managers page. 00:10:45.320 --> 00:10:48.080 If we just go down to the Marks and Sessions 00:10:48.150 --> 00:10:51.860 table, each session name in these columns is hyperlink, and 00:10:51.920 --> 00:10:55.059 that hyperlink is going to take us to the Sessions 00:10:55.120 --> 00:10:55.440 page. 00:10:56.800 --> 00:11:01.900 So let's click our hyperlink here to go to session 00:11:02.000 --> 00:11:03.120 2020 1041A. 00:11:06.640 --> 00:11:10.520 Note that when we land on the Sessions page now 00:11:10.600 --> 00:11:14.309 we see the default at the top is Results from 00:11:14.400 --> 00:11:15.800 Session solution. 00:11:17.800 --> 00:11:22.790 So if we scroll down now, the Solution Quality Indicators 00:11:22.880 --> 00:11:28.559 table and the Data Availability table both reflect the statistics 00:11:28.650 --> 00:11:30.840 for the session solution. 00:11:33.240 --> 00:11:37.780 This module was written and narrated by Jeff Jalbrzikowski and 00:11:37.860 --> 00:11:39.679 recorded in August 2024. 00:11:40.600 --> 00:11:44.480 For further information, please visit the OPUS Projects homepage.
