Another SurvCE Grid to Ground & Localization Resource

Here is a great resource for Grid-to-Ground and Localization in Carlson SurvCE (specifically Version 5.08)

[ SurvCE_LocalizationG2G_Rev014 ]

Index to the PDF:

Localization & Grid to Ground Scale Factors in SurvCE. 1

Grid-to-Ground. 1

Localizations. 1

Reusing last localization? Clean slate!. 1

001 Start a new job at 10,000, 10,000; use Geodetic North at Ground based at a chosen parcel corner. 2

002 Stat a new job, following a historic plat, matching the original basis-of-bearing but holding exact ground measurements. 5

003 Start a new job, using a custom Low Distortion Projection, based at a central location at the job. Choose the correct projection scale factor so that distances are ground. 6

004 Using the previous job, with LDP geodetic basis of bearings and ground distances (10,000, 10,000.) Hand enter a couple of NGS Control Points using the published geodetic positions. 10

005 Start a new job, retracing an existing survey. Initially use a few points to ‘get on the system’ then after finding the remaining corners, do a multipoint calibration looking for blunders. 11

006 Mix total station shots with GPS measurements at Grid. 14

007 Choose an appropriate Combined Scale Factor based on Job corners. Set a Geodetic (True North) BOB system at the job center. (Tricky because you need raw data at Job Center.). 16

008 Network Leveraging of Localization. 19

01:: I just collected 1,200 GPS field shots in the wrong state plane zone!. 27

02:: I just collected a ton of GPS data in international feet, it should have been US Survey Feet!. 28

03:: I collected a day’s worth of data using an autonomous base position, I would like to convert it to a true base position. 29

Adjusting Data Stored with an Autonomous Base to an OPUS Position. 29

03B:: How to read a GNSS Raw File. 35

GNSS Base. 35

.REF File Description. 36

.RW5 Base File Description. 37

04:: I did not store the base position as a point when I did a ‘Read GPS’, can I extract the base position from the raw file (.RW5) or the ref file (.ref)?. 38

05:: I localized on two points at this job and stored a ton of existing features. Now I realize that one of my control points was actually an offset. How do I save my work?. 38

06:: I just stored a shot with a 40000 foot HI!  39

SP80: High HSDV (HRMS)

Recently (June 18th 2018) I began to hear complaints of high HSDV (same as HRMS) from multiple SP80 customers. Initial complains pointed to a ‘change in the afternoon’ after having no issues in the morning.

I believe that this behavior may attributable to US GPS SV 25 being in the used constellation on the BASE.

If you are having issues with high HSDV the safest thing may be to just turn off SV G25. I would turn off SV G25 on both the base and the rover.

Mission Planning

First off, you may want to check when SV25 will be available at your location. I like the new Trimble / Spectra Precision Mission Planning tool which now works without loading Silverlight (I think it works on all browsers now).

Here is a direct link: [ SP Mission Planning ].

Be sure you get the Position, Time-Zone and Date correct. Once you do, you can use the ‘Visibility’ graph to figure out when SV25 will be available:

0626MissionPlanning

Be sure to get the time zone correct or the displayed local times will be incorrect.

SurvCE / FAST Survey with the SP80

In SurvCE / FAST Survey you can disable G25 by waiting until SV25 is ‘seen’ by the receiver and then navigate to ‘Monitor/Skyplot’ and select the ‘SATInfo’ tab. Click on G25:

0626SatInfo

and UNCHECK ‘Satellite Enabled’.

SurveyPro with the SP80

Go to the ‘GNSS Status’ screen. You can get to this screen by clicking on the satellite icon on most survey screens:

0626SPClickHere

The GNSS Status screen is shown, select ‘Sat Info’ and ‘Show All’:

0626SPSatInfo

now click and hold on the G25 box for three seconds:

0626SPTurnOff

Click on ‘Disable G25’.

PASHS Command

You can manually turn off the satellite with this PASH command:

$PASHS,USE,GPS,25,OFF

Feedback Appreciated

I am not positive that this is the issue and I don’t know for sure that the procedures work. Please let me know if you can verify (or not) and I will update this post.

Good surveying to you!

OPUS: Best Practices

I finished the first revision of my epic term paper! Well, actually it is probably the 6th revision at this point, but close enough.

Lots of people contributed lots of examples (and I am still excited to accept more case studies).

So, if you are a new OPUS user (RS, Static or Projects) and you are wondering why your jobs fail; or you just want some light reading; check this out: [ OPUS Best Practices ].

Some of the big take-aways:

  • 25% of OPUS-RS jobs fail
  • The diameter of the Fresnel zone for GPS L1
  • Why OPUS fails where RTK rocks
  • Occupying past midnight UTC is asking for trouble

Again, if you have additional contributions, send them to me!

Oregon OCRS Zone Coordinates in SurvCE

Question: How would I get on the the OCRS local coordinates?

It is our LUCKY day!!!! ?

They are built in. When you click on ‘Add Predefined’:
1

Drop down the ‘Country’ box:
2

[I bet you are surprised to find that Oregon is a Country now…]

And move down to ‘USA STATE OR’:

3

Highlight ‘OCRS Oregon Coast Zone’ at the bottom:

4

Click the green check mark.

If you want to check a point (as shown in the first document), go to ‘COGO: Calculator: Conversion (tab): then put the dot in LLH->Grid:

5

Enter one of the test points:
6

Click on the Solve N/E button:

7

With any luck (and if the job is metric ?) you will match the check point:

8

In this case, the checkpoint is an EXACT match!

InterGEO 2017: A Few Videos

These movies should have been intermixed with the pictures, but…I don’t know how to do that. So they are on their own page.

The drone parachute device keeps your UAV from hitting the ground at mach 4:

 

The GeoSlam video comes in two pieces. You basically can take this device and walk around in a building and it will map everything in real-time (well, there is a second registration step that is detailed in the 2nd movie.)

 

Leica was showing off the full IMU based tilt compensation on their new GS18T GNSS receiver. They had a competition where you would take 10 shots, the person with the fastest score won. There was a computer scoreboard in the hall that tabulated the results.

But, there was no tabulation of the point results. In other words, it was a race to press the store button on each of the 10 ground marks, but there was no indication if the points stored were even close to correct.

This video shows one of the contestants completing the course.

20170927_082541

Same as yesterday

20170927_085751

GeoZone two story booth. Pretty cool!

20170927_085828

Forest IT Design

20170927_085911

This booth is pretty cool. The front has a cabin with a food cart.

20170927_085924

Gexcel has pixel software and wearable lidar

20170927_090019

I don’t know what they make, but it looked cool!

20170927_090042

Velodyne is the leading mobile LIDAR sensor manufacturer.

20170927_090048

20170927_090226

So, I blew it.

20170927_090239

By the time I figured out there was a historic instrument museum in Berlin, I had no time to run over and check it out. I won’t make this mistake in 3 years when I return next.

20170927_090421

I wanted to purchase this, but I think the German would be more than I could bite off on.

20170927_090428

“Development of Instrument Building”

20170927_090437

“Surveying History”

20170927_090617

Trimble had the entire back of one hall, with AllTerra on the left, Trimble on the right, Nikon back and Spectra back right.

20170927_09063120170927_090700

20170927_090709

I spent 45 minutes playing around with the new Nikon ‘Auto Focus’ manual total stations. There are several modes of operation, but I am pretty sure that I am going to purchase a new TS for myself (like personally). Auto focus is worth having and the new guns are beautiful. Yes, the locks are back!

20170927_090715

I think this company deploys GNSS CORS stations.

20170927_090757

One comment for exhibitors is that I should be able to figure out what you do by looking at your booth. ‘Ahead with Precision’ does not an explanation make.

20170927_090815

I like the orange color and they had a lot of cool UAV’s.

20170927_090858

Gas powered UAV’s look a lot more interesting to me.

20170927_090917

I really want one of these forward looking rotary LIDAR platforms.

20170927_09093920170927_092734

20170927_092759

Unfortunately my picture of the front of the cabin did not focus, sorry.

COWI supplies DEMS and Orthos for Europe.

20170927_092846

Back to the Diamond, ‘Ahead with Precision’ booth

20170927_092917

Nobody actually uses these location stickers on the floor. A waste of time.

20170927_092956

So, I think that this Trimble company provides correction services in Europe. It is a cool looking booth.

20170927_093002

Back to the auto focus total stations. I really-really need_want one. You do too.

20170927_100519

Go Big rotary UAV or GO HOME. It is a big box too.

20170927_100852

It was my real pleasure to meet Huiming Song. He owns HowayGis and is partners with eGPS. Based in Georgia, he also has a company that makes choke ring antennas (Atlanta RFTech). Huiming is a really nice guy.

20170927_104044

More UAV, with Velodyne LIDAR

20170927_104115

Delair has Aerial Intelligence which we can all use more of.

20170927_104153

20170927_104159

Something to do with traffic monitoring and mapping.

20170927_112606

20170927_112715

So, this is not a real tool. Basically these guys put every single instrument imaginable on a 4-wheeler just to grab your eye. It works.

20170927_114114

I have no idea what this was

20170927_114127

Now, this is neat. It is a small cylindar that you place on your drone. if it decides that your UAV has failed it will jettison the parachute and safely bring your UAV to the ground

20170927_114131

I have a movie that I will put online in a 4th blog post.

20170927_114410

Simple to setup flights, simple to fly because the device makes all of the decisions. I really want one of these.

20170927_114444
