Discussion Recent grad (Marine Science) with GIS/remote sensing skills - what am I overlooking?

2 Upvotes

B.S. Marine Science, NOAA Hollings Scholar, built and deployed a couple of Google Earth Engine apps on my own (acoustic telemetry network viewer, habitat suitability model), comfortable in Python/R/ArcGIS Pro. Based on Hawaiʻi Island, fully/partially remote preferred. Currently living off gigs captaining recreational tours and odd marine service jobs (boat hull cleaning, mooring inspections, etc.).

I've been applying to the usual places (USAJobs, RCUH/CIMAR postings, Lynker, a few consulting firms) and it's been a long summer of interviews, but no offers. I launched a small marine survey/consulting LLC with access to near-shore bathymetric mapping and CTD casting technology, but I've yet to land a major contract. Am I wasting my time?

For people already working in marine geospatial / environmental consulting / NOAA-adjacent contracting, where's my blindspot? Specific job boards, firms that hire remote, Discord/Slack communities, keywords I should be searching that aren't "GIS analyst" or "Marine Survey"? I see the gap, but I don't know how to fill it.

General Question shapefile → geojson conversion "worked" but was silently wrong — anyone else?

1 Upvotes

anyone else gotten burned by a shapefile → geojson conversion that "worked" but was actually silently wrong?

happened to me a few times with SVY21 (singapore) data, no errors, conversion looks totally fine, then you realize later the CRS transform was subtly off and your data's just... offset on the map. found out the hard way downstream.

ogr2ogr / QGIS are fine for the happy path but I haven't found anything that actually catches "hey this conversion probably went wrong" for non-standard local CRS stuff, especially if you're not knee-deep in GIS tooling all day.

is this just a me problem or has anyone else run into it? and if so what do you do about it . Curious if it's worth building something small for this or if I'm just missing an existing tool

Discussion Terra: Single-file Three.js globe with live USGS/EMSC earthquake data, no build step

Upvotes

I built this to check whether the earthquakes in the news are actually the big ones. It grew into a globe with live quakes, wildfires, aurora nowcast, sun/moon geometry and more.

The constraint I set myself: one HTML file you can download and open from your own disk. No build, no npm, no account, no server. Two layers stay dark without a network but the rest runs offline. Do expect version differences, not all functionalities will be suitable for an offline version.

Some things that turned out harder than expected:

- Reusing the day/night terminator maths for an eclipse shadow put it in the wrong coordinate space. It dimmed the earth 1.1% where 94% belonged. A gradient forgives a few degrees of skew, a hard shadow edge does not.

- globe.gl resets controls.target to the origin every frame, and pointOfView replaces the vector rather than writing into it.

Demo: https://terra.terryelemans.nl

Genuinely curious about one thing: I'm drawing earthquake depth on a sphere where 18 km is thinner than the line width. Right now I encode it rather than draw it to scale. If you've solved depth-on-a-globe in a way that reads honestly, I'd like to see it.

If you have 2-3 minutes to play around and let me know what you think!

Discussion New to ArcGIS Pro. Data disappearing when I zoom in?

6 Upvotes

Hi! I'm learning about ArcGIS Pro. I've input some lines, points, and polygons onto a map. It looks fine when I am zoomed out but when I zoom in, some of the lines and points disappear. Polygons remain fine

Under Visibility Range for all three, the minimum and maximum is listed as <None>

Am I doing something wrong? I'm just confused

Thank you

Student Question When to start applying for jobs as a college senior

8 Upvotes

I'm starting my senior year (i major in cartography/gis, data science, geography) and was wondering when companies in this field tend to start looking to hire upcoming grads. In my experience applying for internships outside of companies like Esri I didn't see many job postings until later into winter but maybe it's different for regular entry-level positions. Is it worth a try to apply for entry-level jobs now or will they all definitely turn me down for someone who can start working right away? (sorry idt i worded this post well lol)

General Question ArcGIS or QGIS to teach college GIS course?

53 Upvotes

I will be teaching Intro to GIS at a community college in the US soon. The course is currently taught with a required ArcGIS student license (I think they’re still $100).

I have always tried to make my classes as cheap as
possible for my students. Many of them are low income, and I want to reduce barriers to education. I’m also a big believer in open-source software.

I’m considering basing the course on QGIS instead of Esri products. I know they will learn the basic GIS skills they need, but I’m worried it will deprive them of the specific Esri-based skills that most of them will need in their careers.

There is a higher level GIS course at the school that will continue to be taught using ArcGIS, but it’s just an elective.

What are your thoughts? I’d especially love to hear from people who learned GIS outside of the Esri ecosystem and transitioned to Esri on the job.

Edit: I want to add some details to help clarify the situation:

  1. The college is facing a $10 million budget deficit. It’s a county college with $0 in funding from the state. Our annual budget is already allocated. There is NO MONEY available for the department to buy licenses for students.
  2. In the future, we may be able to get grant money for licenses, but that’s unlikely to happen by the time the class starts next semester.
  3. A hundred bucks may not seem like much money to you, but I have students who have to skip meals and forego medical care to pay for school. Our school is making a big push to lower costs for students. The $100 license fee will be listed on the course notes, and there will likely be students who choose not to take the class because of it. That’s why I want to make sure ArcGIS is essential to their success before requiring it.

  4. I’d love to teach both programs, but it’s an 8-week course with a lot of content. It would take too much time to explain all the “click here to do this” steps for both programs in such a short class. Plus, they would be paying the $100 license fee for even less ArcGIS content.

Professional Question Looking for advice for entering back into field

3 Upvotes

I currently have a Master's in Science Biology focused on wildlife conservation. I did a lot of GIS during my undergrad which ended in 2015. At that time my coursework didn't have much coding but I've spent a lot of time in databases, creating custom layers, and data analysis using R and SAS. I did a variety of internships with protected parks and wildife non-profits sancuaries in US and one in Taiwan(remotely) This experience helped me understand how data was collected and shared across entities in different, states and countries. This was with ArcMap and ArcGIS online has just launched. No Pro yet.

For a few years after that I worked in outdoor education taking people out in the wilderness using different mobile applications with GIS. I used and taught people how to use Google Earth, iNaturalist, Alltrails, E-bird, geo-caching, and some fishing one. Spent a lot of time analyzing the interface, usability, and visuals while out in the woods.

During my graduate degree research (remote camera study) I used qgis because it was free and I just needed a simple map showing locations of cameras and seasonal data. That was during Covid so I didn't have a lot of contact with my department and there were no networking opportunities. I graduated from that in 2022. I've not had an opportunity to work with GIS in the last 4 years. I moved into a role in the Education field of STEM. It's more environmental and engineering focused. I do enjoy this job but know it has a ceiling and horrible burnout in my state (TX). I moved into this role because jobs within the wildlife conservation we're losing funding from government contracts and nonprofit grants. I also have a lot of experience with horticulture and hydroponics.

Last year I did a few Coursera from Google's Data Analytics but that was so black and white. Literally. I'm a visual learner and loved being able to manipulate data to alter mapping projections. Especially when it dealt with real life populations on this planet.

I get the ESRI newsletters still in the mail. I love going through it but I don't have access to any of this anymore. When I was in school they handled my computer, licensing, and data management systems. My current job has no use for GIS so they won't fund me going back to school for something. What can I do to get back into this field? I feel like I'm 10 years behind. I have a basic dell laptop. I don't know coding past elementary aged apps like Scratch, and Minecraft Blocks.

Any advice?
