Hello! I want to 3D print my hometown. To do this, I have been trying for some time to find the best way to create a 3D model of the city, because unlike big cities, such a file is not available anywhere. I have tried many options. For example, extracting a 2D map from the Cadmapper website, then lifting each house individually to a certain height through Fusion360, because it is possible to extract high quality 2D files with layers for buildings and roads inside CadMapper. However, this cannot be done for free for the whole city, only for some smaller land parcels.

I want to create one file with the whole city, which I can then cut into pieces, so that each one can be printed and then put together. I am trying to find out where is the best way to extract a 2D map with layers of buildings and roads, which I can then open via Fusion360 (as I think this is the most suitable program for lifting each house separately, breaking the map into smaller pieces, and then of course 3D printing). A good way would be through the TouchMapper website, but there is no way to download 2D files (there is an option to split the map into parts and download each piece separately). There might be a better way. Any advice would be greatly appreciated! Thank you.

I was an ArcMap pro, but I'm now an ArcPro noobie. In AM, it was easy to draw a line across a raster and plot the data as a function of distance. The obvious application was with a digital elevation model (DEM) to plot topographic profiles, but there are other applications as well (e.g., plotting slope against distance). In AP, I can't figure out how do this with any raster, other than elevation, using the 'elevation profile' tool. In other words, how do I manually select the target raster when using this tool? Or is there some other method? Just to provide a specific example, I've created a DEM of 'smoothed' topography using the focal min tool, and now I want to create a topographic profile of this new DEM. How do I tell AP to use this new DEM, rather than the original elevation raster?

TIA

Would xhunt maps include parcel information?

Hello everyone,

I’m working on a topographic map and aiming to recreate the style of Canadian topographic maps, specifically how they integrate a True North-aligned map frame with a UTM coordinate grid.

https://preview.redd.it/mw3u3ekp1g7e1.jpg?width=4505&format=pjpg&auto=webp&s=071d681678f6df8271674c832a3607798a4f8c20

The map area is located in UTM Zone 34N (Western Bulgaria), with the following extents:

• Geographic coordinates: 42°27' to 42°39' N latitude, 23°09' to 23°21' E longitude
• UTM coordinates: 677000 mE to 694000 mE, 4702000 mN to 4724000 mN

My Objective:

1. I want the vertical edges of the map frame to point to True North (TN), as seen in traditional geographic projections.
2. I also want to overlay a 1km UTM grid (from EPSG:32634 – UTM Zone 34N).
3. The UTM grid, in this case, should appear slightly tilted (to the right) due to the grid convergence angle, which I’ve calculated to be approximately 1°32’ at the center of my map.

The Problem:

If I set my project CRS to EPSG:32634 (UTM Zone 34N), the UTM grid aligns perfectly horizontal and vertical, but the map frame no longer points to True North. This is not the look I want.

On the other hand, I initially tried using EPSG:3857 (Web Mercator), but this caused significant distortions:

• At a map scale of 1:50,000, the 1000 m UTM grid lines expanded to about 1350 m, effectively becoming something like 1:38 000.

What I’ve Considered So Far:

• ChatGPT suggested keeping the map CRS as EPSG:32634 for accurate scaling and minimal deformation but manually rotating the map (in Layout Manager) to align the map frame to True North. This effectively tilts the UTM grid as expected.
• I’d like to confirm whether this is the best approach or if there’s a preferred geographic projection that would naturally produce a TN-aligned frame while minimizing deformations for my specific area of interest.

Summary of Questions:

1. Which CRS or projection should I use to ensure the map frame aligns with True North and the UTM grid appears correctly tilted?
2. Is manually rotating the map in EPSG:32634 the most practical solution?

• Are there other geographic projections typically used for this type of map design as well as this geographic area (Southeast Europe)?

Disclaimer: I'm a hobbyist in cartography, not a GIS professional.

Thank you in advance for any guidance!

If I wanted to purchase a 1x1 km photo, with the caveat that I personally have to commission it/request it to be taken, what would be the cheapest way to do so and how would I go about doing it?

Hello! For my final project I need to join median household income data census with San Diego parcels, but I am having a hard time finding the data. I’ve checked US Census Bureau, but my options there are limited. Anything helps!

Hi,

ive been working on a Shapefile (in Arcmap 10.0) which i want to use as a template for Biotope Categorisation. Therefore i would like to have constraints for each attributte of a Feature. The constraint would be a list of optional codes (ABC, CDE, XYZ) which would be the codes for each biotope.

Is there a way to constraint the column for a shapefile so only a string which is also on that list can be written (typed manually)?

I managed to achieve the result in the form of a dropdown menu, but this solution isnt viable for the efficency which i want to achieve by creating this template.

I am greatfull for any information, answer or workaround to this topic

Thanks

I work for a PBM (Pharmacy Benefit Management) company where my primary task is mapping patient addresses and generating reports on nearby pharmacies, including calculating distances. Currently, we use MapBusinessOnline, but it tends to be slow, and we're looking for a more robust and secure alternative.

Key Requirements:

1. Coverage: Need access to the entire USA map. Our regions vary based on where licenses are needed, so flexibility is crucial.
2. Performance: Faster processing for mapping and distance calculations.
3. Security: Since it's healthcare-related data, security and compliance (e.g., HIPAA) are top priorities.
4. Functionality: Ability to handle state/county-level mapping and distance calculations.
5. Ease of Reporting: Generate clear, concise reports for business needs.

I'm considering ArcGIS and QGIS. I know QGIS is open-source, but I'm not sure about its suitability for handling healthcare data securely. If I opt for ArcGIS, what kind of license should I look into for this type of work? Are there any security-specific licenses or enterprise options that you recommend?

Any advice on the best software and licensing options to meet these requirements would be greatly appreciated!

Hello, looking for examples of how to make a map that will display a bunch of different data types for a study area I'm making. I have satellite data, polygons of aerial photos, river discharge, gauge stations (along with how long they've been in operation), river lines, etc. It's a lot to put onto one map coherently and I'm trying to find examples of how to do it without it being an absolute mess. Any help or resources are greatly appreciated!

I am a student/beginner level GIS, taking some online coursework as I also do some lite GIS work in my professional career. In the course I am taking, we are in a section on Data formats, data management, etc and learning about File GDBs vs Personal GDBs vs shapefiles etc, and many times I have seen either this instructor (or in other tutorial videos) when they want to start creating new feature classes or datasets etc, they will go to the catalog pane and create a new file Geodatabase to house these new files. I get that for organization it is smart to keep all associated files for a project in one place like that, but in ArcGIS when you start a new project, there already automatically exists a Geodatabase for that project that has the same title as the project. Why do they typically make a separate geodatabase for their new files? why not just put them all in the one that is already there? is there some disadvantage to doing that?

Also somewhat related in terms of understanding GIS data formats, my instructor also mentions that he recommends running analysis 'within a File Geodatabase format' as opposed to a shapefile format (?) I also don't really understand what difference that would make or how to know what format I am running my analysis in, as I thought within ArcGIS shapefiles don't exist, they are called feature classes until they are exported (as shapefiles), but you can have feature classes within a geodatabase. So I don't really get the concept of running analysis in different formats in that way..

I'm trying to develop some GIS metadata guidelines for my organization, and maybe even some Python tools to automatically enforce metadata consistency between our FGDB/Shapefile, SDE, and Cloud-based (Portal, ArcGIS Online, Open Data Hub) geospatial data repositories.

I recently learned that some HTML tags are permitted in AGOL metadata. This leads me to wonder: Is this support for custom HTML universal throughout Esri's product line? For instance, if I download a heavily marked-up AGOL feature layer as an FGDB, is my markup still going to be viewable in ArcCatalog or ArcGIS Pro? What about compatibility with QGIS, or search engine crawlers like Googlebot? And how about any accessibility considerations with screen-readers for the visually impaired, etc.?

I'd love to start using HTML tags like <table>, <span style="background-color:darkgreen; color:white">, and <img src="data:image/svg+xml;base64,PD94bWwgdmVyc..."> to spice up my org's metadata. But I also want to be compliant (or at least compatible) with the North American Profile ("NAP") standard.

Any tips for HTML-metadata best practices? Anything I need to be aware of? Thanks in advance for any advice!

Are there any that are so easy to use that a complete beginner can easily use it? Ideally one that has a simple user interface, intuitive buttons / tools, provides starter datasets, can be meaningful used in just a few minutes, etc.

Hi everyone,

I’m in a bit of a dilemma and would love some advice from those experienced in the tech field. I’ve been admitted to both MSc Cybersecurity and MSc Geoinformatics & Spatial Data Science in Germany. I have 2 years of experience as a Systems Engineer in a service-based company, where I primarily worked in system administration, and I hold a BTech in Information Technology. I’m also proficient in Python and R programming.

My main concern is which program will offer the better salary potential and job opportunities in the long term.

• For Cybersecurity, I know the field is growing fast with a lot of demand for professionals, but I'm curious about the job market and salary expectations in the coming years.
• On the other hand, Geoinformatics & Spatial Data Science seems like an emerging field with applications in urban planning, climate change, and various other industries, but I’m unsure about its salary potential compared to Cybersecurity.

Given my background in system administration and programming, which field do you think has a stronger outlook in terms of salary and job opportunities, especially in Germany and Europe? Any insights on the job market for either field would be really helpful!

Thanks in advance for your help!

Hi all, I have never worked with sewer data before. Just curious, why do I see very few local governments publish sewer pipeline datasets like they do with other stuff on the open GIS portal? Are they less frequently digitized? What are some helpful resources for me to look into? Are they usually paid data?

Thank you all so much!

Hey all,

I am a Canadian mineral exploration geologist with about 3 years industry experience. For a number of reasons, I am looking to move on from the rotation/travel heavy lifestyle. I am interested in potentially persuing a career transition over to GIS.

I am curious which industries/sectors tend to compensate the highest, both in early and mid to late career? Considering my background and interest in natural sciences, I am interested in potentially forestry. I have a friend at UBC in forestry, and reassures me that "you don't get rich in forestry" (not that I am naive enough to believe GIS will make you rich all in all). She is also not as computer savy, and uninterested in the office work/analysis/software dev/engineering, etc.

Money is by no means my primary motivator. I am simply interested in the world of GIS and Geospatial Data. But.... coming from mining, it's harder to face the inevitable pay cut that I would get working a job based more or less out of one home base!

I understand that I will need specific GIS training to make this transition. My beginnet industry QGIS knowledge is by no means fit yet!

Thanks in Advance!

Cheers

I’m a 21 year old Social Science Student looking to get into a geography related field in the future. Geography has been my special interest since childhood, It’s really the only interest I’ve never stopped caring about at some point.

Up until two years ago, I didn’t expect to ever go to college (long story lol my high school grades were terrible). As a result, my school options were limited, and the only college that accepted me didn’t offer any geography related programs or GIS courses.

About a month ago, I got an ArcGIS personal use license and have been practicing with it in my free time instead of my usual Google Earth exploring. I’m definitely still a beginner. I understand GIS use cases, basic geoprocessing tools, how to make visually appealing maps and layouts, and a few other fundamentals, but that’s about it.

I’ve been having a lot of fun using the software, and as I mentioned before, I think I’d really enjoy doing something GIS related as a career. That said, I’m uncertain if spending so much time learning GIS on my own, without any formal coursework or certification to show for it, is an inefficient use of my time and effort.

If it is inefficient, what steps should I be taking to maximize my effectiveness and build my resume outside of just transferring schools?

Thanks in advance!

I've been told many times over that breaking into the GIS industry is not easy. I have been applying for GIS jobs on and off for more than half a year now and not one interview. I do have some great prospects in the works atm, but they could take months to get back to me. I can't just wait to see if they pan out.

I'm getting a second wind in pounding the GIS pavement. This would be a great moment to reevaluate my GIS resume. For those of you who do hire for GIS positions or at least know what employers are looking for nowadays, what should a recent GIS grad have on it, and if we don't, get on it?

Keep in mind I'm in my late 30's and for me, this is a career change. Does that help or hinder my chances?

TY you in advance!

Hi All!!

I'm at my wits end a bit with this dataset (https://doi.org/10.25380/iastate.c.6005185.v1). I installed their compressed files for temperature data, and the value ranges in ArcGIS don't make any sense (https://postimg.cc/r0cVcMBM). The documentation doesn't mention anything about a conversion of these values...

is this just a dud dataset? Am I being a bit of a dunce? Have tried it for multiple days of the data with no luck :(.

EDIT: Found it! The data is listed in "the unit of 0.1 Celsius temperature", so essentially need to bump a decimal point forward. I guess this is a friendly reminder to really inspect the README file😂

Hi! I'm in my second semester of my freshman year at university. My major is currently a B.S in Environmental Science with a concentration in sustainability. I'm having difficulty deciding which major I should pursue to pair with my GIS minor. I'm considering geology, geography, or environmental science.
For reference, I am in lower Alabama.

I'm interested in wetland delineation, surveying, consulting, conservation, or any type of field work where I can be on the ground. I'm really interested in working with wetlands. I've done one major project in an upper-level geology course where we surveyed multiple properties and generated a report using ArcGIS and some other programs - I did well and found it interesting.
I would like to add I am not math inclined whatsoever and have been holding on by the skin of my teeth in my math based classes so far.
This is why I'm hesitant to take the advice of some other posts here and do engineering, statistics or some other math orientated degree.

Do any of you have any advice for which major I could pursue that would be attractive to employers? I love the classes I'm taking in my degree right now but I realize environmental science degrees are very common and are broad. I appreciate any feedback. Thank you in advance!

This is extremely confusing!

Hello, I am looking for links to good data repositories. What are the main repositories that you use? are there places that you can go to find a clearinghouse for GIS data? I am looking for all kinds of data, but in the conservation and biodiversity space.

Please post links. TIA!

Is it possible to have the measuring tool snap to the headings of the cardinal directions (0, 90,180,270)?

I am using it to help write utility locate tickets for very specific locations

Where can I find the best resources to learn how to create maps using R's Leaflet package? I came across a LinkedIn course, but it requires a premium subscription. Are there any other free and effective learning resources available?

So lets say we have this map and in QGIS / Python we want to extract the shown data in a way that we locate each text passage and take the geometrical centroid of each text element itself and store the text values in the attribute table of this newly derived point geometry (centroid). How can this be achieved? My guess would be at first you gotta georeference the picture by hand and then work with some OCR algorithm via the python console? Anybody has an idea? Cheers!

I am currently doing a B.A in Geography with touching a few Calc classes and soon a Physics class + learning program languages like Python and SQL. Also thinking of dipping into remote sensing analysis. Climate science has been an amazing interest of mine due to climate change and its effects/risks. After hearing from someone about the booming sector of climate tech and renewable energy, I was also interested in careers related to them. Climatology has certainly been on the top for me, especially with topics like sea level rise.

For those with jobs in the climate and renewable energy, what are some career pathways I can take? What do you recommend to prepare for a job in that field? How has your experience been? How has the pay been? Thank you!

Did ESRI outsource their support services overseas? The last 5 cases I’ve had the people who call barely speak English, have a very hard time understanding the issue, refuse to communicate over email only over the phone and are clearly reading a script they have a hard time pivoting from. Anyone else experiencing this?
