What does vertical datum refer to? Is it Mean Sea Level (MSL)? Is it a zero mark in the tide gauge? Is it some other height value than zero, far from the tide gauge? Is it one reference benchmark? Is it all the benchmarks in the levelling network? Is it the combination of all these?
Relevant answer
Answer
A vertical datum is a type of reference surface used to measure the heights or depths of objects and features relative to a common point of origin. This common point of origin is typically referred to as a benchmark, which can be either a physical or virtual point with a known elevation above or below the datum.
The choice of vertical datum to use will depend on a few factors, such as the intended application and the geographic location. For many countries, Mean Sea Level (MSL) is the most commonly used vertical datum. MSL represents the average height of the sea surface over a period of time, and it's often referred to as the tidal datum. This reference point is used to measure elevations and depths of objects relative to the water level.
However, in some cases, a different datum may be necessary. For example, in areas that experience significant land subsidence or sea level rise, a local datum may be used to achieve more accurate measurements of elevations and depths.

We have been repeatedly surveying areas thousands of km from the coast. I think critical to use magnetic data from laboratories in the continent who also might be influenced by local thunderstorms. One possible way is to attach a magnetometer to an oceanographic anchored buoy.
I can analyze if an anomaly is real by observing its behavior in two paralel lines but that will not account for diurnal variation at the day of each acquisition. Therefore, amplitude and any estimates for depth might be erroneous.
My regards, Oderson/Geol. Survey of Brazil
Relevant answer
To evaluate magnetic diurnal variation in marine surveys thousands of kilometers from the nearest magnetometer on the coast, you would need to use a combination of different techniques and approaches. Here are some possible methods:
  1. Use an onboard magnetometer: One way to measure magnetic diurnal variation is to use a magnetometer on board the ship or vessel conducting the marine survey. The magnetometer can be calibrated to account for any instrumental drift and the Earth's magnetic field, allowing for accurate measurements of magnetic variation.
  2. Deploy remote magnetometers: Another option is to deploy remote magnetometers on buoys or other platforms along the survey area. These magnetometers can be linked to the ship's navigation system, allowing for real-time measurements of magnetic variation.
  3. Use satellite data: Satellites such as the European Space Agency's Swarm mission can measure the Earth's magnetic field with high precision and provide global coverage. You can use these data to estimate magnetic variation at the location of the marine survey.
  4. Predict magnetic variation: Magnetic variation can be predicted using models that take into account the Earth's magnetic field, solar activity, and other factors that affect the magnetic field. These models can be used to estimate magnetic variation at the location of the marine survey.
It's important to note that each of these methods has its limitations and uncertainties, and combining multiple approaches can help to improve the accuracy of magnetic variation measurements. Additionally, regular calibration of the instruments used and careful data processing are critical to ensure the reliability of the results.

For my master thesis i'm surveying 200 salespeople to see the effect of wellbeing programs on productivity. They are split into 2 groups, 100 for control and 100 where i apply wellbeing programs.
The DV is number of sales (continuous), and there are more categorical IVs(likert scales)(e.g ' how often have you felt worn out, how often have you felt stresses) all those questions are showing levels of wellbeing but not directly linked with wellbeing in the question. Should i rephrase them to 'does wellbeing help with stress or does wellbeing program help you feel less worn out' because i didn't find any statistical test to help me with the this relationship.
Is there a statistical test to use or should i rephrase them all?
Relevant answer
Answer
Hello Andrei,
It appears the chief question concerns whether participation in well-being programs helps explain differences in sales. If you're willing to consider sales as a metric variable, then an ordinary t-test or one-way anova or the equivalent regression model (one IV, group membership, and one DV) would allow you to address that question.
Now, on to the proposed covariates. If you measured these in advance of the treatment, then they could in fact serve as covariates (and, as ordinal values, you might wish to consider a solution such as ordinal regression, or simply dummy code each of them and run a hierarchical or stage-wise regression).
If you did not measure them in advance of the treatment, you're likely better off considering them as outcomes as well, and compare the groups on each. As these are ordinal, you could use a method such as the Mann-Whitney U test, Norman Cliff's dominance statistic, or ordinal regression.
Good luck with your work.

Dear all,
we are preparing a multibeam survey on the Canary Islands and ask ourselves which GPS RTK service would allow for smooth operation near the south coast of Lanzarote. Fugro marine star is not accurate enough, we need a "real" RTK service providing positions in the centimeter accuracy level. Most preferentially we would like to catch the signals via mobile internet near the coastline via NTRIP. We would highly appreciate recommendations or shared experience for canary island surveying ;)

Dear all, the issue has been solved. We use online RTK via Ntrip from a local GPS reference stations nearby. The corresponding service is hosted by http://www.grafcan.es/ and a yearly subscription cost 200€ for our academic surveying.

I'm working on my thesis, trying to estimate the population density using only capture-recapture data. This data was obtained by surveying the study area for almost three years nearly everyday.
I am confused on how to work with this though, as every single day has captures and recaptures, and don't really know how to limit an event from another one to use classic methods such as Lincoln-Peterson.
As such, I'd like some help working on how to precisely estimate this population size for two species, considering almost every day has either a capture or recapture.
Relevant answer
Answer
The Mark-Recapture technique is used to estimate the size of a population where it is impractical to count every individual. The basic idea is that you capture a small number of individuals, put a harmless mark on them, and release them back into the population.

If you intend to find and identify wild boar over larger distances (up to 1500m) in open country, you should maybe try a device with higher resolution (640 x 480). We used a Pulsar Helion XP50 in our project to spot wild boar at night and found it very useful for a quick overview. At a distance of 50m, you're going to see details as thin as hair.

Let's say there is a questionnaire in which some items are about peer relationships and some about romantic relationships. Consequently, participants who are not in a romantic relationship at the time of surveying are instructed to leave the 'romantic' items blank, thus creating missing data. Would you consider the data MNAR (missing not at random) or MAR (missing at random) in this particular case?
Relevant answer
Answer
@Daniel Wright, @David Morse, thank you for your responses.
I will try to explain some details - the project is aimed at verifying the structure of a questionnaire that is supposed to consist of three correlated factors - two of them are about peer relationships and one is about romantic relationships. I want to perform a CFA on an adult sample.
The most logical thing would be to include only the participants who are in a romantic relationship and to exclude those who are not - that way I don't have to deal with missing data and think of ways of handling those. I was curious, however, whether it would be a good idea to use the whole sample without deleting anyone and rely on methods like Full information maximum likelihood estimation. Although, as far as I know, FIML requires the data to be MAR or MCAR and I wasn't sure if that's the case here. I hope this clears things up.

Well, it seems low, but I don't know enough about the material to really say. I do know that, while CV can be very good for getting capacitance, if you don't have the correct setup, it won't work, and you're better off with EIS or galvanostatic charge/discharge.

I am doing my Masters dissertation on the Development of a sport in a country while studying the behaviour and motivation of sports fans. I have chosen the mixed methods approach to collect my primary data where I am going to Interview the manager of the sport's governing body in that country at the same time surveying the fans in that country. I am not sure what to write in the Research Design and Research Philosophy sections of my methodology. What should my Research philosophy be and which Research design describes my project best?
Relevant answer
Answer
The claim that "research philosophy is an important part of the research methodology" is an idea that emerged in the 1980s, along with the interpretation of this philosophy as consisting of concepts such as ontology, epistemology and axiology. Prior to the work of Lincoln and Guba (most notably in their 1985 book, Naturalistic inquiry), no one paid much attention to these issues, but were still able to produce quite successful research with both qualitative and quantitative methods, as well as in the emerging field of mixed methods.
Since the early 2000s, there has been less and less emphasis on Lincoln and Guba's version of the research philosophy, especially in mixed methods. One major influence has been the rise of pragmatism as an alternative that does not depend on ontology on epistemology. In my opinion, however, the biggest reason for the decline in interest in ontology on epistemology is the realization that they made little difference in the actual conduct of research, and that the real issue was the linkage of research goals with research methods.

I hope that I simply need an additional conditions or a totally different approach.

I am wondering what would be an acceptable sample size when you are trying to survey a population that is hard to access, especially if you don't have access to data that indicate the size of that population in the first place. Thank you !
Relevant answer
Answer
Geraldine - very difficult to state. It depends on certain factors. Do you want to/need to generalise? If that is the case, you need to have an approximate idea of the total population and then you could perform a power calculation to predict the minimum sample size. In absence of that, then the required number is subjective and most likely to be 'as many as you can get'. You might state a subjective minimum i.e. 50 that you feel you could do anything 'meaningful' in terms of interpretation of the collected data.
Whatever the number, be aware that recruiting hard to access populations is usually a long and laborious task - and may have to employ techniques such as snowball sampling.

The purpose of this research study is to determine whether or not Physical Therapist’s (PT) feel that at home monitored exercise regimens will increase amputee compliance regarding prescribed rehabilitation programs. For this reason, we will be surveying certified Physical Therapist’s through online survey portals, asking them to complete a short 10-question survey. If you are willing to participate, our questionnaire will ask about, (age, gender, geographic work location) as well as years of certification, perception on the amputee population, and views on prescribed home based regimens. There are no foreseeable risks associated with this survey, and there is no benefit to you. This is entirely an anonymous questionnaire, and so your responses will not be identifiable in any way. All responses are confidential. Your participation is voluntary, and you may withdraw at any time. This study is being conducted by Tyler Berger, who can be reached at (517)-215-2616 or tjb113@pitt.edu, if you have any questions.

As is well known and from theoretical proofs, proper weighting of the least squares solution of a leveling network is inversely proportion to the distances between the leveling points or the height difference between pairs of points. In other words, the uncertainties or the relative contribution of different observations in the least squares solution of the leveling networks are expressed in terms of distances. Sometimes the uncertainties of the existing control information are expressed in terms of their standard deviations, which were estimated from their previous dispersion or variance-covariance matrices. Although this type of expression or representation of uncertainties is very common, it makes the integration of the uncertainties of the existing control information to a new leveling network a non-trivial task. Now the question is:
What is the best weighting strategy for the observations and the control points? In some cases the control points will be introduced as fixed constraints, which can be viewed as some sort of a non optimal pseudo inverse solution.
Relevant answer
Answer
We recommend to use a combined stochastic model, i.e. an individual uncertainty (for each observation/waypoint) and a length-depending uncertainty, see Eq (24). The length of the survey line ignoresthe terrain profile and a levelling loop of e.g. 100 m in a horizontal terrain profile has the same weight as a levelling loop of 100 m in the mountains but different numbers of waypoints. If the number of waypoints differs from each other, the uncertainties cannot be the same.

I want to conduct a reaearch without that typcal students sample and a broader variety of professions included. Does anyone have experience regarding response rate and representativity?
Relevant answer
Answer
To my understanding, anything advertised within your network (any social network) would be regarded as convenient sampling. However, if you have LinkedIn premium membership, you can access to vast number of professional, whom you can short list using search function. I have used LinkedIn in first case but not in the latter case.
I believe in latter case, you can have total number of professional short listed based upon their job description, so that would be sample frame and the number of responses that are returned can be used to calculate response rate.
Another option could be making use of Google URL Shortner or Bit.ly to track number of clicks form LinkedIn and other social network and number of actual response. Then you can say use the No. of actual responses/No. of clicks to show how many people accessed the questionnaire and how many responded. I have done the same in my recent data collection to track the respondents. You can more information on respondents using both of above mentioned services.

As I know survey could help me to gain data (even the perception, feelings) from the large number of students so that I can classify them according to the level of anxiety to conduct the in-depth interview further.  So, Is the survey as I've described called qualitative survey even it comprise theclosed-ended questions? and Does it mean that I am completely doing the qualitative research? 
 Hope to see your response!
Relevant answer
Answer
As you say at the beginning, what you have done is a survey that included open-ended items. with regard to mixed methods, the key issue is how you integrate the results from your two types of methods. For example, you might do an analysis of your quantitative data, and then use the qualitative data to interpret those quantitative results. This can of research design can be represented as QUANT --> qual, where the core set of quantitative results determines your use of the qualitative data.

I want to have the best system solution for a very light( low weight) aerial survey
Relevant answer
Answer
It also depends a certain amount on the particular drone aircraft you intend to use.
Some of the very small UAVs currently being used, in Fukushima for example, can only lift 1-2kg at best. Whatever you put on such aircraft is going to be limited to dose rate only.
There is at least one aircraft system in use with a 3-5kg payload, which is enough for a small (2x2" or 3x3") NaI(Tl) or Cs(I) detector. If you are investigating relatively simple mixtures of radionuclides (eg: naturals and 134Cs, 137Cs, or 60Co) these detectors will give adequate capability of nuclide specific mapping. If you need to know what's there without any prior information then you'll need the spectral resolution of Ge or CZT - but you then have very little sensitivity. If you have the money, a CeBr or LaBr detector should be a reasonable compromise between sensitivity and spectral resolution.
We recently flew a mid sized NaI(Tl) system that would be available for the larger drones (with 20-30kg payloads), and this has given good results even at 500m over parts of the Fukushima deposition.

Question

In navigation we have 3 types of position accuracy: predictable, repeatable and relative.
Which type of accuracy should define the minimum requirements for positioning systems in various applications: maritime, air and land navigation?
Relevant answer
Answer
The most important criterion must be the purpose to which the user wants to put the system. Such questions as:  "Is he returning to a place he has been?" and "Is he navigation to abstract coordinates provided?" will quickly answer whether absolute or relative is appropriate.
Each of the applications you posit have very different environments in which to operate. 
  • Airborne navigation has few nearby landmarks useful for confirmation. Takeoffs and landings are short-lived exceptions.
  • Waterborne navigation will often have some useful landmarks except in open sea. Near to and at port landmarks are frequent.
  • Landborne navigation usually has a plethora of useful landmarks with the possible exception of desert travel. Swamp and jungle may provide too many similar marks to be useful.
The three types of accuracy estimation to which you refer are commonly defined as follows:
  • Predictable:  sometimes called geodetic is a measure of how close to coordinates of a certain datum the navigation system is able to perform consistently. 
  • Repeatable:  is a measure of how close to a place visited previously, with the same equipment, the navigation system is able to perform consistently.
  • Relative:  is a measure of how closely a measured position agrees with another similar system at the same time. This is very like repeatable accuracy, but across the whole type of system instead of just one system alone.
There is another, often more, possibly most important, accuracy estimation that should be considered for navigation while moving.
  • Dynamic:  is a measure of the aforementioned criteria while the system is moving. A properly tuned Kalman Filter will always make a good navigation system better and a poor one acceptable. It is often the case that a system may be optimized for static operation, which detracts greatly from dynamic performance. A system tuned for an aerobatic platform will serve a cargo vessel poorly.
A fishing charter operator who has visited his "hot spots" and wants to return to them with clients will want a repeatable system and benefit if it is also predictable.
A pilot ordered to rendezvous with a midair fuel tanker will require predictable and relative accuracy and hope the same for the tanker. Both need excellent dynamic accuracy.
A crop-duster will want predictable and dynamic accuracy usually augmented with differential corrections.
An automobile driver's system usually has an additional "cheat sheet" in the form of a background map. The system can afford to have less predictable accuracy by assuming the vehicle is on a road and display position by forcing the illustration to show the vehicle on the road nearest instead of where it is actually calculated.
On the other hand, a farm implement has no road map to guide its report and it is moving. His requirements are very similar to the crop-duster but without the degree of risk.
A hiker will benefit most from a predictable system with good static performance because he may stop to take a position and orient.
I hope this is helpful. I firmly believe there is no one answer with the exception of "give me all three improved and it will be better."
Best wishes,
JAC

3. Use simulation utility of orbitron with your updated location --> jump intervals of time to simulate the GPS constellation for future times (or location)
4. For a suitable point of time (may be each 30 minutes), select a GPS satellite on the right hand bottom "skyplot" window
5. When a satellite is selected - click on "ROTOR/RADIO" tab --> you can note the elevation and azimuth of each satellite --> Note down the elevation and azimuth of all GPS satellites (above the cut off mask) for this particular point of time.
6. You can use any DOP calculating s/w for each point (of time OR location)
7. We have developed a program to do the same that calculates PDOP values fairly accurately from elevation and azimuth of satellites, please let me know if you need support.
