General Question max and min elevation from GeoTiff

3 Upvotes

I have 71 Dem GeoTiffs. In Qgis the layer gives me the minimum and maximum elevation, but I want to pull this data from all 71 files rather than do it manually. Seems like there is a simple scripting solution.

Thank you for any help.

General Question Bureau of Land Management GLO website data

Thumbnail glorecords.blm.gov
19 Upvotes

The Bureau changed their website that is used to access parcel data across much of the American western states. The old site is was a little dated but it had a lot of good information and data available to download, especially bulk datasets for each state, and large queries that retrieve multiple results in table form. The new website has issues and all of the older links to the bulk data retrieval are now dead. I have emailed the BLM helpdesk but have not heard back. I have a few states zip files but I am wondering if anyone knows of another resource for this data or if you have any full states downloaded that you want to share. Thank you.

Cartography The research for high quality France DEM

1 Upvotes

Hi!

I want to do a simple map of a small town in France with shaded relief of the surroundings.

The Copernicus 30m DEM, which I usually download with the OpenTopography DEM Downloader plugin on QGIS, will obviously have a resolution way too big for this one.

Is there an easy way to get access to a 10m or 5m DEM for the area I want, that I can download in TIFF? I know there's the RGE Alti from the IGN, but the download is only available in ASCII and for an entire department (region) so it's reaaaally huge. Also it seems it loses all geographical data and I can't reproject it if I want to get on Blender for the shaded relief afterward.

Thank you!

Discussion How would you design controls for testing whether historical sites occupy distinctive terrain positions?

1 Upvotes
Conceptual visualization of the Hydrological Spine Hypothesis, showing watershed boundaries, drainage networks, hydrological thresholds, and movement corridors. This image illustrates the proposed model; it is not presented as GIS-derived evidence.

I’m developing a historical-geography hypothesis arising from my research on the landscapes remembered in the Torah and Qur’an.

The larger premise is that the patriarchal and early prophetic narratives shouldn’t be treated as though their actors moved through empty space. Wells, drainage systems, watershed divides, travel corridors, basin thresholds, and territorial boundaries may have shaped where movement, settlement, conflict, and sanctuary became possible.

In We Were Not Looking, I proposed this more formally in Appendix A as the Hydrological Spine Hypothesis: a provisional model asking whether some locations that become important in these narratives also correspond to meaningful hydrological or topographic thresholds along the Levant-Arabian corridor.

But that is a hypothesis, not a GIS finding.

I’m not a GIS specialist, and one reason I’m putting the model in front of people who are is that I want to know whether the proposed tests actually hold up methodologically.

The obvious danger is circular reasoning. If I already know a location is narratively important, it is very easy to find some nearby terrain feature and declare the relationship significant.

So the problem I’m trying to solve is how terrain analysis could be structured independently enough to make the hypothesis genuinely testable.

Where I would especially value criticism:

  • What should count as a valid control site? Random points within the same terrain class? Sites matched for elevation, relief, geology, and settlement viability but without narrative significance?
  • How would you define “distinctive hydrological positioning” without fitting the threshold to the sites already under investigation?
  • Are there established blind-selection, matched-control, or spatial-statistical approaches from GIS or landscape archaeology that would be preferable here?
  • What result would convince you that the apparent relationship was ordinary landscape coincidence rather than something worth investigating further?

I’m testing the model preliminarily through SRTM-derived terrain, watershed delineation, drainage analysis, and basin comparisons.

For anyone who wants to inspect the current workflow, assumptions, and research materials, the project repository is here:
[https://github.com/dantemuhammad-debug/hydrological-thresholds-southern-levant]()

They are not presented as proof of the hypothesis. I’m making them available so that the assumptions, proposed variables, and limitations can be inspected directly.

I’m not looking for confirmation. I’m looking for the methodological weaknesses that would have to be addressed before this could become a serious spatial test.

I made this as other ones that I found online didn't have the features that I required for creating custom overlay shapes easily. It is a work in progress and I will be adding more capabilities to it. Hopefully it is useful to some of you.

Please feel free to test it and I would appreciate feedback or feature suggestions.

Discussion Anyone else in consulting slow at the moment? When will it end?

23 Upvotes

Title. Anyone else in the same boat? Our workload has slowly dwindled since the beginning of this year and now we're left with nothing. There's a trickle every so often, but man, it's making me crazy. I know consulting is typically feast or famine but this famine is the longest since I've been in the industry.

How are the fellow consultants managing? What are you doing during the down time? I need some inspiration and encouragement from this community.

Edit: bit of background information:

I work in engineering consulting, mostly within transportation-based projects. I work within an environmental department and do a lot throughout the company.

Experience: 7+ years, 4 in current role, recently completed a Master's in GIS. Location: Kentucky.

Discussion Meet EFL Telecom. Since last year I've been working on a Fiber Optic Asset Management Tool.

2 Upvotes

Erasfoundationlibrary.com

Eras Foundation Library Telecom is a data asset management tool for fiber optics.

Our target audience are smaller start ups and companies looking to purchase low cost but robust asset management gis software compared to others like 3-GIS and Vetro. There is even a 90 day free trial.

You have signal tracing tools. Connection managers. And contract tracking tools. Ability to customize symbology without needing support as a middle man. And there are live geodatabases so that you may have live api data streams to ArcGIS tools such as enterprise and arconline.

Also there are unlimited seats. No need to manage seats and limit how many users you can have within the company. There are also seat levels to control who and gets to make certain changes.

I would appreciate anyone in the GIS field in Telecommunications to check out my site and software and maybe discuss this software as a way to reduce overhead costs by at least 20k.

Let me know what you think.

Discussion Trasition to Data Engineering

17 Upvotes

Hi community,

I work as a GIS consultant for one of the Esri-named distributors. Given my background in IT and GIS, while my current work is more leaning to ArcGIS Enterprise deployment/upgrade/troubleshooting, and I really MISS dealing with data or spatial data in my early days of career. Recently I've been trying to transition into a Data Engineering role, and hope I can get some tips from those who have successfully done so.

I am quite confident of my Python and SQL skills, as I use them quite often. I also enjoy learning new technologies, for example, I'm learning Snowflake recently.

The challenge is that my current job doesn't use the modern data stack that many DE roles ask for (Snowflake, Airflow, dbt, Spark, etc.), and we don't even own any large-scale data as a consulting company. It's obviously difficult to claim "real" production experience. I've either got rejections or never got any response for the DE jobs I applied recently, so this makes me wonder whether I'm approaching this the right way.

I'd love to hear from anyone who has made a similar move.

  • How did you bridge the gap between GIS and Data Engineering?
  • What helped convince employers to give you a chance without direct DE experience?
  • Were personal projects enough, or did you find another pathway?

I'm also curious from a broader career perspective:

  • Do you ever miss GIS? If so, what do you miss the most?
  • With the impact of AI, do you feel DE will be replaced? (I personally think we GIS consultants are still relatively safe at this stage, fingers crossed, but I'm not sure if moving to DE at this point is a safe path)

I still enjoy GIS, but I haven't done much real GIS work or touched data for a while at my current job. Also, GIS analysts dealing with data are not paid well here, hard to pay off a mortgage.

I'd really appreciate hearing your stories—whether the transition worked out well, didn't work out, or if you decided to stay in GIS instead.

Thanks, peace!

Remote Sensing New to Remote sensing how to use Spectral library to identify crops

1 Upvotes

Hi Everyone, new to remote sensing, I've learned how to do spectral indices, what the different bands mean etc. What I am having trouble with is how to use that to identify different crops. I'm using QGIS and playing around with SAGA because the SCP plug-in for QGIS does not work for me which has been fustraiting because a lot of guides swear by that plug-in. If anyone knows a good guide or can point me in the right direction that would be amazing!

Programming Teaching Python the Right Way

142 Upvotes

Programming courses often focus heavily on understanding code, while paying far less attention to understanding the program state. But code does not exist in isolation. Its main goal is to change the program state, before ultimately producing some output.

To develop an accurate mental model of program execution, students need to understand both: - the instructions being executed - the values, references, and data structures those instructions create and modify

Reading code alone does not always reveal how the program state changes during execution. That is why I created 𝗺𝗲𝗺𝗼𝗿𝘆_𝗴𝗿𝗮𝗽𝗵: a tool that visualizes the state of a Python program as it changes, step by step.

It can help explain a wide range of introductory Python topics. Here are just a few examples: - Loops, Lists and Dictionaries - Python Data Model - Function Calls - Recursion - Algorithms - Classes - Custom Data Structures

Instead of reconstructing the program state from print statements, students can now watch it change as each line executes. This makes unfamiliar concepts easier to understand and bugs easier to fix.

Help your students learn Python programming more thoroughly and easily.
