### Land Surveying Formulas

The subject area of land surveying is very interesting and to become a licensed land surveyor you need to understand and be able to put into practice a wide range of land survey formulas as the majority of land surveying is based around mathematics and physics. In today's guide we shall look at land survey formulas in more detail.  And if you are a Land Surveyor, here is an entire forum and hub for sharing surveying formulas.

## Origin and History of Land Survey Formulas

The wonderful thing about land surveying is that even though it has been around since records first began, the methods and formulas have barely changed.

Land survey formulas have always been based around mathematics and physics and use fundamental rules of each of these subject areas to create land surveys.

Back in the times of the ancient Egyptians land survey formulas were much more basic and used simple rules of geometry to conduct their surveys. While the basics are still the same today, thanks to increased knowledge in the field of mathematics land survey formulas have become a lot more advanced and have allowed for increased accuracy in land surveys.

Below we shall look at some of the main land survey formulas that are used around the world.

### Types of Land Survey Formulas

There are hundreds of different land survey formulas, and each one serves its own purpose. Whenever a land surveyor is required to do a land survey they must first establish which land survey formulas are most appropriate for the type of land they are working with.

The type of land survey formula they use also depends on the type of survey that is being done. There are dozens of different types of land surveys, some of which are more complex than others.

For land surveys that cover huge areas of land, the land surveyor will usually use a land survey formula that takes into account the curvature of the Earth to ensure a more accurate land survey. However, for smaller areas of land the land surveyor will tend to use a land survey formula that assumes the land is on a flat plane as the curvature of the Earth has such minimal effect.

Some land surveys only require the boundaries of the land to be measured, whereas others require the height and contours of the land to be mapped as well. The chosen land survey formulas will suit the type of survey.

## What Kind of Math Do Surveyors Use?

### Algebra and Trigonometry Land Survey Formulas

Algebra and trigonometry make up a large number of the most commonly used land survey formulas. Trigonometry land survey formulas are typically used when measuring the height and angle of the land. In fact, land surveyors are one of the most prominent users of trigonometry formulas.

Basic algebra is incredibly useful for land survey formulas as it is used to establish length, area, volume and more - which are essential for land surveys.

Other land survey formulas include quadratic equations, spherical trigonometry and spherical coordinates. Land surveyors must have a strong and thorough understanding of all of these land survey formulas and they form a huge part of any land surveying college courses.

Probability and Statistics Land Survey Formulas

Probability and statistics are two other types of land survey formulas that are well utilized within the profession. These two areas are important when it comes to data collection and interpretation - a major part of land surveying.

Areas of probability and statistics that are most commonly used in land survey formulas include: standard deviation, variance, test of significance, error ellipses, data distribution and histograms.

Geodesy Land Survey Formulas

We mentioned earlier how many land surveyors need to take into account the curvature of the Earth to allow for the most accurate land surveys of large areas.

Geodesy land survey formulas can be quite complex and are similar formulas as those that are used by astronomers.

Some of the geodesy land survey formulas include: geodetic data, gravity fields, reference ellipsoids, conversion from geodetic heights to elevation and orbit determination and tracking.

Geodesy land survey formulas are some of the most complicated used by land surveyors and it requires intense levels of knowledge and study before they can be perfected and used.

Frequently Asked Questions Raffle and Membership

A few members wrote in because they were unable to find their member number.

I managed to not only fix this, i went ahead and updated all of the new members in the community so now everyone in the network up to yesterday 5PM EST should now be in the system and you can find your member number more easily.   I streamlined the process a bit on the Memberships/Raffle page.  When you find your Member Number, please make a note of it as it will never change from this point forward.  You will want to have an easy way to reference your Member Number on the last day of every month as it will be your chance at winning the entire Raffle Prize for the Month.

Note:  From this point forward, new member numbers will be added to the system on the 15th and last day of the month.   So if you joined the community after the 1st or 15th, your member number will be retrievable on the 16th or on the day before any scheduled raffle drawing.

When I upgrade my membership, does that qualify me only for the month that I upgrade?

No.  You get at least 12 chances to win... All levels of membership apply to your member number for the entire year beginning when you upgrade your account.  In other words, if you upgrade as a Basic Member, you get 1 Raffle Number Per Month for 12 months.  So you have 12 tickets with different prizes available every month.  For example, for \$50/yr you might win a Total Station or a GPS package or a software suite.  The most important thing is what you also get with your membership such as access to private sections of the community, access to all of the deals and rewards of the Smarketplace, in addition to the upcoming Survey Education Courses and App coming in early February.

Ok, So how many chances to win the raffle do I actually get when I upgrade?

For Basic Membership - 12 Tickets 1 per month.

Best suited for individual member

For Futurist Membership - 24 Tickets  2 per month

Best for those who can sponsor a member who cannot afford membership

For Masterclass - 60 Tickets  5 per month

Best for Member + 4 sponsored members with extra perks for purchaser

For Big Boss - 240 Tickets  20 per month

Best for company owner and sponsorship of employees with major business perks..

If I purchase a Futurist Membership or higher, do I have to give my extra raffle tickets to those I sponsor?

By sponsoring another surveyor who cannot afford membership, you have the choice of either giving your sponsored member the raffle ticket or keep it for yourself.  By sponsoring another member you double  or triple increase your chances of winning but it is up to you as to whether or not to keep the extra raffle ticket or give it to them.   Once you are matched with a member to sponsor you will be given a short bio about who you sponsored with information such as how long they have been surveying, where they are located and most importantly, their Member Number, which you will essentially become owner for purposes of the raffle.

Thank you for this feedback.  Today I have added the ability to purchase your raffle tickets using Cash App and I am working on Stripe and other integrations.   If you have a preferred payment method that you would like for me to try adding, please tell us here.

Absolutely! Helping a fellowSurveyor who cannot afford membership pushes everyone forward. Reward yourself for your gesture, if you like. For example,You'll get 2 raffle tickets per month as a Futurist or higher and it is your choice to either keep their raffle ticket or give it to the member you sponsor. As a Futurist, you essentially become the owner/steward of the Member/Raffle number associated with the member you sponsor. You will also be given a choice between 3 members to sponsor based on their relationship and experience in land surveying. As a sponsor you will be providing access to all of the educational tools, resources and knowledgebase for a member who otherwise would only have restricted access.

I am a Student or Retired Surveyor who cannot afford Membership

IMPORTANT:  If you are not making money as a land surveyor, we have you covered, but you need to let us know.   If you do not let us know, we will not be able to remove the restricted access from your account and therefore you will only be seeing 20% of what Land Surveyors United Community has to offer you.  There is a place inside the memberships page for you to explicitly tell us that you are not currently able to afford membership.   By filling out this form, we will be able to match you with an available sponsor.   Once the parties are in communication, it is between you to decide how raffle tickets will be distributed. In other words, your sponsor may choose to keep your raffle number which means they essentially own your Member Number for the year and will have 12 chances to win with your number.  Nevertheless, you will be afforded all of the access and permissions to access restricted areas and resources that a Basic Member will have across the community and all member apps.

Where do the Raffle Prizes come from?

Every month of 2021 and beyond, our community is sponsored by a different Marketplace Vendor who we believe you should reach out to and get to know.  The raffle prizes will all be a showcase of the best of the best offered by these vendors, who have all been hand chosen based on customer service quality, willingness to support what they sell and overall feedback across the community.   Those vendors recieve an entire month of our community support and love in exchange for their sponsorship of our unity for the month.  For example, Safety Apparel is the sponsor of January as it is Safety Month and the high quality safety gear they provide our members saves lives every single day.   We celebrate them. We follow them.  We share what they are doing in the world to make land surveying better and so should you.  At the end of the month, a Major Mega Survey Party Pack of vests, gloves and accessories will be awarded to the winning Raffle Member Number.   It is true that we shall celebrate Safety Apparel every month of the year, but their month to shine in the community is the entire month of January.  In February, Survipod becomes our Sponsor of the month and we will showcase their innovations and will raffle a prize at the end of the month.

NOTE:  Our 2021 months are starting to fill up quickly and there are presently only 6 months left to claim, so if you would like to be showcased for a month in 2021, please get in touch asap so you do not miss the opportunity to get your products/services in front of thousands of surveyors around the planet who want to test them out, use them, love them, hate them but most importantly, get to know your company/brand better..

What if I want to purchase the same products showcased in the raffle from the Sponsor of the Month?

You do not need to win the raffle for the month to own the products provided by our sponsors.  In fact, if you contact the sponsor and let them know that you are a Land Surveyors United member, they have all agreed to provide a special member discount for you when purchasing the products they offer.

What if I am not a land surveyor but I have a profile on Land Surveyors United?

If you have a profile on Land Surveyors United and you are not a land surveyor, you must be a special case.  However, I must inform you that our member raffle is for Land Surveyors only.   In other words, if your member number is drawn and you are a) not a land surveyor and/or b) you have not upgraded your membership, we will draw another number.  Only those numbers which coorespond to a member number matching an upgraded membership are eligable to win the raffle prize.

Note: All profiles which are not Land Surveyors, Students, Retired Surveyors, Geoeducators, Seeking Employment, Recruiters or Tech specialists have restricted access and will only be able to see certain sections of the community, apps and resources.   Many sections of the site will only be visible and usable once a member profile has been upgraded.

This is YOUR Community!  Is there something special that you would like for us to add or integrate into the Surveyor Community for you?    Do you have a feature or add-on that you would like for us to develop?

Tell Us What Would Like to See Us Build Next

It may be true that you have created 2 profiles in the past 15 years, but the account that you currently use is the account that you upgrade for Basic Membership and as such will be your winning numbers. If we draw the number of your previous account and it has not been activated, yet we see that you have upgraded your current account, you are still eligible to win. As long as one of your accounts is upgraded in good standing, you are eligable to win the prize, if we draw the number associated with your account that you no longer have access to.
We update the member numbers on the 15th of the month and the day before the last day of the month (day before any raffle). If you joined recently, check back on the 16th or after the first as we assign new numbers every two weeks and the day before a raffle.

Differences between Forums, Blogs and Article posts

Blog Postsdiffer from Forum posts because you can embed and upload different kinds of information.  Blog posts are best for presenting information and updates for feedback and sharing.  When posting a Blog Post, you can also publish a short excerpt at the bottom which is what most members will see before reading the blog post.  Blog posts are also great for posting new surveying projects and digests of links to multiple surveying topics or your own website.   Things that can be embedded into Blog Posts are videos, images, slideshows, powerpoints, spreadsheets, PDFs, documents and more.

Articles are similar to Blog Posts in all ways except one.  Articles allow for you to post an Author Block at the bottom with links to your contact info, website information, credentials, etc. Similar to Blog Posts, things that can be embedded into Blog Posts are videos, images, slideshows, powerpoints, spreadsheets, PDFs, documents and more.  Similar to both types above, Hub Owners can add article sections and features to any hub they control on the community.
