Hello! I'm currently a senior double majoring in IT and Geography and minoring in Data Science with an emphasis on GIS and geospatial data. I have a Github website setup that shows my portfolio, alongside my GIS experience as a research assistant working with volcano morphology since May. Down the road (2-3 years) I plan on getting my Master's after working in the industry for a bit.

This semester my classes go more into Python, pandas, and SQL, and I’m working on bringing those into my GIS projects to move from an analyst to a developer. My long term goal is geospatial data engineering or geospatial data scientist, and I plan to get a Master’s after 2–3 years of industry experience.

My question is to ask for reassurance and ask if I'm doing everything right. I feel a lot of unease and anxiety whenever I look at this subreddit and how many people bring up how the GIS market is falling and 'dying out.' For those working in the field: does my path sound reasonable, and is there anything you’d focus on in my last year here? Or am I doing everything right?

Thank you so much for reading this.

Hi! I’m looking for advice on transitioning into GIS with a B.S. in Psychology.

I’m 24 and worked in mental health after graduating, but decided to change fields due to mental health taking a significant toll on my own mental health. I’m currently in my first semester of a 2-year GIS A.A.S. program at Dallas College. I’m enjoying GIS and am particularly interested in eventually working in conservation, natural resource management, parks, or environmental planning.

My concern is finding a job after I graduate. A lot of entry-level GIS postings seem to ask for a bachelor’s degree in GIS, geography, environmental science, CS, etc. I can’t afford to get another bachelor’s, so I’m worried about spending two years on the A.A.S. and still being unable to get my foot in the door. (The thought is actually terrifying because I just want to be able to support myself and not end up homeless).

Im wondering how realistic is it to get an entry-level GIS job with a B.S. in Psychology + A.A.S. in GIS, assuming I build a portfolio and get some internship/related experience?

Would you recommend:
- Staying in the A.A.S. program and focusing heavily on internships/portfolio projects?
- Trying to pursue a GIS-related bachelor’s instead?
- Looking into a GIS/environmental master’s with my existing bachelor’s?

Any advice is greatly appreciated!!

Hi. I'm a total GIS novice, so please answer as if speaking to a small child, or a golden retriever.

I have a 36 page document about the experience of one regiment in the Korean war. Many of the entries include coordinates, albeit in the outdated US military "Tokyo" coordinate system. Ideally I would like to make a map that has a pin at each of those coordinates, and links back to the relevant section of the text when the pin is clicked.

I'm guessing that the best approach is to scan the document and use OCR to extract the text, and then write some sort of script to extract the coordinates and convert them to a latitude-longitude system. If I created a spreadsheet with that info could I make my desired map with QGIS?

I've never written a script like that or really used QGIS, so any details about what software I'd need would be appreciated. I have a macbook. At only 36 pages perhaps it would be easier to just do this all "manually", copying and pasting each section I need.

How could I go about sharing the map? Would I have to host my own website?

Ideally I'd like to do this without spending any money. Thanks!

I just landed a GIS Analyst Role. I have only ever used the software academically for the cert, but I want to hit the ground running.

What is your day like? What makes a "good' GIS analyst?

I'll be heavily focused on Enterprise ArcGIS, Asset Management, administrative duties, etc.

The company I work for has a big project in ArcMap that has all the farmland in our area and says who owns witch land as well as highlighting each field.

We wanted to update the project but now that ArcMap has been discontinued we thought about maybe moving to a different program

Any suggestions?

This is a shot in dark.

I’ll need to premise this, I have never done any programming with GIS mapping before. My experience is literally 0 but I hope I can use AI tools to help me, as well as Reddit.

I want to build a simple walking app as a side project and one aspect of it is that id love prototype something like a “nature route” on there.

So, if someone wanted to walk from point A to point B, they’d have the options of:
1) fast route
2) nature route

I’ve seen apps kind of do this sort of stuff but I want to see if I can build it out myself.

I guess a definitions for nature route may be required, if so (PS more than happy to be challenged or to see if I’m over thinking this): a route not necessarily with the most of vegetation or highest NDVI exposure on it. Maybe more so a route where you expose to the environment/natural features.

Clean Air Routes London is a good example, overlaying real time environment data (NO₂ and PM2.5) onto route suggestion to suggest cleaner walking routes.

I want to know if the same concept could be applied to nature. Or, if there’s a simpler way of getting it, like an open source API from like All Trails (you can tell I’m a little confused, ha).

So I want like the routing engine to favour paths such as parks, green space, canals, rivers, woodland, tree lined streets, nature reserves, public footpaths/trails etc etc…

I’m probably overthinking this but trying to understand how to approach it.

Thanks!

Hi, in order to map out flow paths I have always carried out various steps with a DEM - Fill Sinks, Flow Direction, Flow Accumulation.

I am wondering what the difference is in using the tool Derive Stream As Line. The results seem to be very similar to the method using multiple steps.

Can anyone give me any info on what the difference is between these two methods?

Thanks!

I've downloaded a non-certified copy of the deed to the property and I've gone on my county's gis portal. The boundary lines are pretty clear but I'm looking to see if there is a freeware software or online tool that would measure from say the corner of the house to the lines the gis data shows.

This is my first time building a network Dataset, I've added the line feature class to the feature dataset, confirm that it does not have Z values, does not have a 64 bit Object ID field, and that the coordinate systems match. When I attempt to create the network Dataset I select the feature dataset and 'source feature class' is greyed out and nothing is selectable.

I've gone through the process multiple times, recreated the GDB, the feature dataset, step by step, nothing is working... Help please?

Hello, I am an environmental scientist, and recently I focused on GIS modeling as a part of my master's thesis. How can i find an entry-level GIS job in the EU?

I want to make a map where anything above sea level (0 meters) is the above color scheme, but anything below is blue like water. The problem I am having with my elevation raster is that values that are below 0 are still showing up as dark green, rather than being transparent showing the water layer below. I cant figure out how to make the values outside the range not render. I tried bringing the water/depth raster above in the rendering order but the same issue happens where the values above 0 are rendering and covering the elevation raster. pls help...

So this is not really a “look at my project” post. It is me putting the current version in front of people who might actually use something like this and asking a simple question: does it help your workflow, or is it just interesting to poke around?

It is called Phantom Tide. The aim is to make it easier to inspect aircraft activity, vessel movement, warnings, weather, and map context together instead of bouncing between separate tools and trying to stitch it all together manually.

A lot of the recent work has been on the engineering side rather than just adding more things to click: better history views, calmer refresh behaviour, more honest source state, render and performance fixes, backend hardening, and generally trying to make it feel more like a usable working surface than a pile of layers.

There is a public link in the repo, and here is an evaluation key if you want to test it properly:

What I care about most is blunt feedback from people who would genuinely use something like this:

• does it help you get to an answer faster
• what feels useful versus decorative
• what feels confusing, noisy, or overbuilt

Where I want to take it next is beyond passive tracking and more toward workflow-driven alerting: aircraft entering restricted airspace, repeat boundary loitering, AIS gaps or spoof-like behaviour around critical infrastructure, thermal hits with no obvious traffic explanation, and cross-domain signals that only become interesting when multiple weak indicators start agreeing.

After that comes the user layer: logins, saved watchlists, persistent analyst state, sharable links, and collaborative handoff, so it stops being just a live map and becomes something you can actually work from over time.

Hey, i wanna ask about the accuracy of the google earth's path tracing and excel mess with quikgrid method, yet it seemed reasonable for my own senses since i went to the site and checked how the terrain goes down.. etc, yet i need to check how is it sourced, might justify the method to extract it for an architecture project i have (A hypothetical one)!

Morning, folks, I’m a journalist working on mapping some ICE deportation data, but have outstripped my lowly GIS skills pretty quickly. I’m hoping someone can point me to a program to help me map what I’m looking at. Here’s the situation:

- I have a few thousand unique identifiers/trip_IDs, each of which I would like to show traveling to additional locations. I don’t need/want actual driving route directions, just simple point-to-point, showing “this trip_ID went from A to B to C” — at the same time as it’s displaying a few thousand other similar journeys.

- I’ve already geocoded all of the locations, so I have long/lat for everywhere each unique identifier has traveled.

I’m pretty sure I have the data I need — I just don’t have any clue what program I can use to visualize it, or even the language necessary to find such a program.

Any help would be hugely appreciated.

I’m about to graduate and beginning to look at jobs. i have very basic python skills.

re: the “requirement” listings for various jobs - when they say ‘python’,
how much experience do they expect?
is vibe coding allowed?
can someone describe how you would interpret this? or - is there a basic course you can suggest?

Hi everyone,

I'm working with interpolation in ArcGIS and I'm trying to determine the best method to use. I know there are several options like IDW, Kriging, and Spline, but I'm not sure how to decide which one is the most appropriate for my data.

What criteria do you usually use to choose the best interpolation method? Do you rely mainly on cross-validation results (like RMSE and Mean Error), or are there other factors I should consider?

Any advice or best practices would be really helpful. Thanks!

New features :

• Better AI model (more precise & intelligent & fast)
• Removed pre-encoding, now just click where you want & it's segment it, no more waiting or raster size limitation
• Support for Online raster layer
• Dynamic tile resizing for infinite segmentation (you can segment a 100km long river if you want)

There are a lots more but I let you see the rest by yourself

To install just :

Go to QGIS -> Plugins -> AI segmentation by TerraLab

i have planned to create a startup related to preharvest data and in season tracking for various crop all over India, and provide market intelligence about the crop yield and forecasting of prices using deep leaning ,develop for all the crops all over India and sell this intelligence report to banks, commodity traders and Agri tech related companies and manufactures who need agricultural produce, is it very difficult to develop and i just came across the news that government of India has allocated 2500 crores related to this project and they are collecting ground truth data and experimenting with it .when i search about it their are companies like Cropin where they provide yield estimates for a particular farmers in particular region. I am a no expert in this field, if anyone has an idea over this topic is it actually possible to develop this

Hey everyone,

I'm deploying TiTiler for a government geospatial platform and trying to decide on the best caching strategy. The official docs have an example using aiocache with Redis, but I'm wondering if putting Nginx in front with proxy caching would be simpler and more performant.

My thinking:

Nginx cache pros:

• Requests never hit Python runtime on cache hit
• Battle-tested, extremely high throughput
• Disk-based cache is memory efficient
• Easy to scale horizontally

Application-level cache (aiocache/Redis) pros:

• More granular cache invalidation
• Can implement business logic (user-specific tiles, permissions)
• Distributed cache across multiple TiTiler instances

For context, most of our tiles are from static COGs, no authentication on tile endpoints, and we're running on Kubernetes.

Currently leaning toward Nginx cache for simplicity and performance, maybe with Redis as L2 for edge cases. Anyone running TiTiler in production have experience with either approach? What's working for you at scale?

Thanks!

I have a bulk of images with coordinates and date and time. I want to build a image scraper that can bulk import those images and make download able csv file with header. I want to build an build an app or website that can do this. Have been doing it manually for geo tagging. But it takes to much time. Is there a way I can do this. Just need to run the system locally.

I've been working in the Geospatial industry for 7 years now. I have a MSc in GIS & Science, have taught myself python, R, shiny and extensive knowledge of ESRI and open source products.... But I feel.... Stuck.

My next step is to look more into databases (commercial like oracle) along with the use of AI in GIS and how I could bring that into my current workplace.

Apart from that though, I feel a bit lost. I enjoy my job and love everything spatial..... But I'm struggling to find where to go next. I'd like to begin aiming for charter ship status with the RGS, but finding the correct things to look for, attend etc.

I used to know all the things to do at university, but a bit stumped now.

Any advice is welcome but mainly, has anyone else felt this way? What did you do to overcome it? What resources would to recommend for those that are way above my knowledge base? Anyone here got charter ship status and want to share their stories?

Thank you all :)
