New Look for Parallax!!
2026-01-01
We have been concerned about how well the Central Coast Chapter’s website serves the members and local surveying community for some time.

The site is set up as a blog, where the posts are shown in chronological order down the page. When we created this site that seemed like a great way to present information to the surveying community. What we have found is we generally get mulitple post at the beginning of the month, so if we have a long posts, some new fresh post do not get many views because it is so far down the page.

This format does not work the best for how we use our website. We are more of a news type website than a blog type. We believe it would be better to have a site that has a short excerpt of a post and then a link to read the full post. This allows many more of the posts to be seen quickly.

We are hoping this format will enhance the website and make it more of a hub for the chapter.

Also – Looking for a Website Editor:

Takes about 4 to 8 hours a month

Excluding articles written by the editor

Need to know or want to learn WordPress Web content management system

Primarily use site editor for managing the website
Work with blocks
Understand the administrative site also

If interested contact Chapter President, if you have questions about the site contact Tom Mastin @ tbmastin@gmail.com

Vernal Equinox
2026-03-20 07:46 - 19:47
From Wikipedia (Full article here)

A solar equinox is a moment in time when the Sun appears directly above the equator, rather than to its north or south. On the day of the equinox, the Sun appears to rise directly east and set directly west. This occurs twice each year, around 20 March and 23 September.[a]

An equinox is equivalently defined as the time when the plane of Earth’s equator passes through the geometric center of the Sun‘s disk.[7][8] This is also the moment when Earth’s rotation axis is directly perpendicular to the Sun-Earth line, tilting neither toward nor away from the Sun. In modern times[when?], since the Moon (and to a lesser extent the planets) causes Earth’s orbit to vary slightly from a perfect ellipse, the equinox is officially defined by the Sun’s more regular ecliptic longitude rather than by its declination. The instants of the equinoxes are currently defined to be when the apparent geocentric longitude of the Sun is 0° and 180°.[9]

Global Surveyors' Day
2026-03-21 08:00 - 17:00
The path to Global Surveyors’ Day began back in ancient Egypt when society first used surveying techniques to divide land. Throughout history, surveyors have remained the pioneers of discovery shaping our world to its current existence by exploring the unknown on earth and in space. Fast forward to 2013 when the signing of the Budapest declaration created a common worldwide celebration for those leaders, past and present. We are proud to proclaim Global Surveyors’ Day as a way to globally recognize the ground-breakers, pioneers, individuals and the industry that has shaped our history and continues to be the foundation of our communities.

Where survey firms are quietly losing money (Free Educational Webinar)
2026-04-08 08:00 - 09:00
Hi,

Most survey firms don’t struggle because they’re bad at surveying.

They struggle because no one ever taught them the commercial side of running a survey business.

Across the industry, we’re seeing the same pattern again and again.

Not a lack of work …

… but a slow, quiet leak in revenue that most firms never measure.

It usually shows up as:

time spent on the wrong activity

discounting just to win work

missed projects you never even hear about

fixing things later that should’ve been built properly from the start

Individually, none of these feel like a big deal.

But when you add them up … it’s often $$$’s a year.

So we’re hosting a webinar to break this down properly, in a way that actually makes sense for surveyors.

No fluff. No “just post more on LinkedIn” advice.

Just a clear look at where the money is going, why it’s happening and what to fix first.

If you’ve ever felt like your pipeline is more reactive than it should be … this will feel very familiar.

On the Trail of the Changing Alaskan Geoid: Results of the 2025 Geoid Monitoring Survey

Presenters:Ryan Hardy, PhD, Geodesist and Geoid Modeler, NGS Gravity and Heights Branch;Kevin Jordan, Cartographer, NGS Field Operations Branch

In the fall of 2025, NGS followed up the 2021 geoid monitoring field campaign to measure geoid change in southcentral Alaska’s rugged valleys. In this webinar, NGS presenters Ryan Hardy and Kevin Jordan will discuss the challenging gravity, GNSS, and astronomical observations required to create a high-resolution snapshot of how the gravity and heights change over time. This survey has mapped out the accuracy of GEOID2022 in this region and revealed accumulated changes in orthometric heights since the Coast & Geodetic Survey’s high-precision survey following the 1964 earthquake. The data from this campaign will be used to improve the spatial resolution of GEOID2022’s dynamic component.

The Trig-Star Program began in 1984. The idea came from Russell E. Kastelle, RLS, who was a member of the North Dakota Society of Professional Land Surveyors. As the ACSM Delegate / National Society of Professional Surveyors (NSPS) Governor from North Dakota, Kastelle’s idea came from a desire to promote the surveying profession. Originally, designed to operate only on the local level, Trig-Star soon grew to include the National Competition and scholarship opportunities.

When Kent Green proposed that NSPS sponsor Trig-Star as a national contest to NSPS president, Richard Lomax, they created the first Trig-Star Committee. Chaired by Larry Doss, they worked to develop national testing guidelines and secure funding for awards and scholarships.

Over the years, volunteers and state societies, such as the Wisconsin Society of Land Surveyors, have improved the testing instructions while Don Murphy, John Chagnon, Tony Gregory and others worked to ensure that the format and standardization remain consistent with educational criteria.

Santa Barbara Subdivision Fee Hearing
2026-06-09 09:00 - 10:00
The Santa Barbara Board of Supervisors will consider a Public Works Department proposal for an Ordinance Amending the Public Works Department Subdivision Map and Document Review Fee Schedule – Surveyor Division.

The Board of Supervisors Hearing is scheduled for June 9, 2026, starting 9:00 AM, at the County Administration Building, Board Hearing Room, Fourth Floor, 105 East Anupama Street, Santa Barbara.

This item is on the agenda to recommend that the Board of Supervisors extend the pilot program that subsidizes a portion of the fee for the review of Records of Survey in the unincorporated area of the County for an additional year, to allow time for the Department to conduct a comprehensive study of all County Surveyor fees, including the Record of Survey fee.

The link to the Agenda Item attachments is below.

COGO’s 2026 National Spatial Data Infrastructure (NSDI) Assessment Surveyhttps://www.surveymonkey.com/r/COGO_2026_NSDI_Survey

National Spatial Data Infrastructure (NSDI) Assessment Survey

Every four years, the Coalition of Geospatial Organizations (COGO, https://cogonetwork.org/) conducts an assessment of the National Spatial Data Infrastructure (NSDI) in the United States. COGO is a coalition of 14 national professional societies, trade associations, and membership organizations in the geospatial field, representing more than 170,000 individual producers and users of geospatial data and technology. The purpose of the assessment report, next to be published in 2027, is to help advance the NSDI by identifying areas where attention and focus are needed and to highlight opportunities for collaborative work across entities at all levels of government, industry, and the private sectors.

This survey is a primary source of data for the assessment report writers. We seek the input from both expert and non-expert users of geospatial data. The survey contains multiple sections: one that asks about the NSDI as a whole and then separate pages for eight NSDI Framework Data themes. Once you complete this first section, you will be able to choose which of the other data themes to respond to, if you wish.

COGO thanks you for your time and thoughtful attention in contributing to this important effort.

The deadline to respond is June 12.

The survey can be found here:https://www.surveymonkey.com/r/COGO_2026_NSDI_Survey
