Water Utility Salary Audit - GIS Developer Type Role + Other Stuff

As of the new fiscal year, it looks like I will be taking on a new role from my current "GIS Coordinator" role. I am wondering how I am looking compared to the market, and also just interested in sharing for overall transparency in the field. For reference, I am located in the south, on the outskirts of a medium sized city. I have roughly 4 years of combined experience, am fluent in python, js,

My Current Role:

Currently, I am a sole GIS person for a small water utility. I do everything from field data collection, to create web applications (both with AGOL out of the box, the ExB SDK, and other Flask Apps.). I also assist with customer service.

In this role, I am currently making $50,000/yr with 100% insurance paid by the employer and 5% 401k contribution, and an annual bonus.

The New Role:

In my new role, I will still have my previous responsibilities +

  • Become responsible for managing our work order/inventory system (including building a custom application for this).

  • Become responsible for managing our backflow prevention program (including building a custom application for this).

  • Become responsible for managing water consumption and water loss for the utility.

With the new role, I will be making $63,000/yr with the same benefits + 75% reimbursement for the masters program I intend to start this year.

Overall, I feel like my salary without taking on the additional department/program management responsibilities should have been near $63,000 given the level of custom development, etc. However, I feel like when factoring in the benefits at the new level, I will be making out pretty nicely for still being "Early Career" and will come out with a Masters.

What are your thoughts?

How do I get a Value to show up in my legend?

Hello, I'm wrapping up my first GIS class in college and I cannot, for the life of me, figure out what I need to do to replicate the original document.

I don't think I need to replicate the original Legend, but I would like to for readability and I'm having a hard time describing my issue in any way that Google can understand.

Insurance for GIS professionals (small business owners)

Background: I've been in GIS for 20 years and have a one-person-shop consulting business (based in FL, USA). I'm in the middle of insurance policy renewal season and am curious as to what other small business owners are carrying and the cost. I am generally required by clients to carry GL and E&O, but also carried cybersecurity insurance last year. Here are the estimates I'm receiving for renewals (prices in USD for one year of coverage):

GL: ~$1,000 ($1MM per occurrence/$2MM in aggregate or better)

Cyber: ~$1,000

E&O: ~$2,000 ($1MM per occurrence/$2MM in aggregate or better). This seems to be the minimum policy limits that I can obtain and that my clients will allow.

I've searched this forum and found $2,000 for E&O is probably a decent price (answers went up to about $3,000). Just wanted to check in and see what others are paying this year.

Related aside: Has anyone left the business/closed shop and obtained a tail policy?

Geo pivot internship?

Anyone have experience with this? I was working as a lidar technician but my contract was not renewed, I am currently applying for jobs and I am hoping to go into a more GIS heavey position. My main barrier is experience, I have a degree but the internship I was supposed to do during my degree was cancled due to covid.

I am applying for every entry level position I can find including internships that don't require you to still be I school or positions that have gis but aren't directly a gis role, but I am getting nowhere.

I saw this online but I am worried it would just be a scam/ pointless.

Does anyone have experience with Geo pivot internships, it's a remote internship to get experience but you have to pay( hence why I think it's a scam). Normally I wouldn't bother with somthing like this but i cant seem to get anywere applying for jobs so I wish there was a way to get experience to help move the needle, I applied to some volunteer positions but never heard back. My other options are additional certificates like UAV licience or thermography( I have seen them on some job listing's but I don't know if they would help in general). Get my masters, I don't know if it would help but maybe it might make me eligible for more internship positions.

What is the starting salary like in Alberta for a GIS technician? Should I upgrade my diploma to a geography degree?

I have my diploma in geomatics engineering technology and I am going to COGS for the advanced diploma in GIS this fall. After I'm done I'm hoping to get a gis technician job or something similar. What kind of salary can I expect as a GIS technician in Alberta? I have one year experience in land surveying and a 4 month coop as a geomatics technician with the federal government. Will this experience along with my diplomas help me land a GIS job? I also have the opportunity to upgrade my geomatics diploma to a geography degree with another 2 years of study. Would this be worth it if I already have the advanced gis diploma from COGS?

Iceland Data

Is there a good source of free spatial data regarding Iceland, preferably in English? I found one source that I have to pay for, and the Iceland GIS portal is ... to no one's surprise... entirely in icelandic. If anyone has any leads for good data, it would be appreciated.

FeatureSetByName

I’m struggling to execute this the exact way I need it. I’m trying to write an arcade expression to return an attribute value from another layer on my map into my popup. My code is returning the first thing that intersects with my data although that’s not what I want and incorrect (I’ve tried to use Contains rather than Intersects but it won’t execute).

Here’s what I have so far:

var building = FeatureSetByName($map, “Buildings”); var prop = First(Intersects($feature, building)); var addr = prop.ADDR_ID; return addr

Does anyone know what I’m doing wrong/can send me some helpful documentation on how to correct this? Ideally I want to build my pop-up by pulling in attributes from other layers based on a key field but I haven’t been able to figure that out either. Thanks!

Getting slope for 100k+ points

Anyone have any recommendations for finding the slope for over 100k points all within the state of California? I use ArcGIS Pro, I normally use the Summarize Elevation tool but it doesn’t work on more than 1000 points and the slope imagery on the Living Atlas is just too big for me to really do anything with it, I can’t even extract just the area I’m working with. Appreciate any recommendations!

Help showing spatial relationship with two sets of data

I am working on a project and I am trying to show public street security cameras and bike lane locations. I have both sets of data in my project (bike lanes and cameras) but I am trying to only show the lanes that have cameras.

The data for the bike lanes and cameras have different syntax for the street names. Is there a way I can relate or join this data together to get it to allow me to show only the bike lanes that have cameras on them?

I am newer to gis but this is my first time showing a relationship between two separate sets of data. I have been looking at spatial join, and there are many options in there but none seem to be working.

Join Resulting in Fields with Null Values

I am trying to join a CSV to using the common field GEOID. When I execute the join, the fields are added, but all the values are Null.

In the layer, GEOID is text data type and in the CSV, the same field is a Number data type. Is this the issue? I tried fixing this in excel but the GEOID codes are so long that if I convert them to text they end up in scientific notation.

Are there other aspects of this operation I should be considering?

View from PostGIS Not Drawing in QGIS

I'm playing around with PostGIS in PostGres and trying to visualize Views in QGIS. For some of my views, I'm getting the strangely emphatic "Unavailable Layer!" message. I had this problem with some views I made a few days ago but eventually resolved it, but don't quite remember how! I think it may have had something to do with narrowing the view down with queries that returned only one row per geometry value.

Some rudimentary reading shows that unique integers might be the key for getting SQL queries to show up in QGIS. For my successfully visualized Views there are incidentally unique integer values but otherwise no Serial-type columns.

I've played around with getting Serial ID columns into my final view but it's built around a subquery with GROUP BY operators that don't seem to like the addition of another column. Am I missing something, or am I on the right track?

Learning on My Own - Real Estate

Hey all, I’m am looking to develop more skills in my work place and I have an option for ArcGIS. I have little to no experience here but am skilled in excel, with some SQL and R experience too from business school(though it’s been a while - 3 yrs), mostly self taught.

If I want to use ArcGIS just for running things like commute analysis, how difficult is this going to be to teach myself?

Essentially if I go to my boss and say I want ArcGIS, and say I can deliver commute analysis for clients, is it feasible I can teach myself these skills in say 2-3 months? I know this is broadly speaking but is it generally doable?

Thanks!

Most Useful ESRI Courses

Hey all, I currently have access to all of the ESRI training courses through my university but I'm graduating in December and want to get the most out of my subscription before then. I already have a good amount of knowledge and experience with arcpy and non-GIS cs skills but I am interested in gaining more development skills beyond that. Also, I have an internship with a utility company so some courses to prepare me and/or go along with the experience I gain from that to assist in finding a job after graduation would be super helpful. TIA!

how’s the UK job market like for GIS?

Hi! How’s the job market like for GIS related jobs/internships, and are they open to international students on graduate visas?

Also, are they usually contract based or do companies look for long term employees (and thus avoid hiring people on graduate visas)?

what kinda jobs should i look out for, and what portals should i use? i googled entry level GIS jobs and only got 30 searches.

The degree I plan to study: BA Geography KCL, spatial data pathway

Thanks!

Phone Geofence Alert App?

I am looking for an iPhone app that provides a notification when my phone crosses a geofence. Use case: I crossed city limits yesterday when doing site inspections and didn't realize it. I'm currently working off of paper copies and a list of addresses, no map (long story; will be electronic next year).

The city limits currently exist as a polygon AGO service.

Clipping Temporal raster in ArcGIS Pro

As part of a script I am running, I am clipping the  Sentinel-2 10m Land Use/Land Cover Time Series data from ESRI (https://www.arcgis.com/home/item.html?id=cfcb7609de5f478eb7666240902d4d3d) using Python. I was using the previous version no problem, however, with this version of the data, when I do my clip, as default it clips the oldest version of the raster, whereas I actually want the latest / most recent version of the land cover. Does anyone know if its possible to specify this in Python? 

esri_lulc = "https://ic.imagery1.arcgis.com/arcgis/rest/services/Sentinel2_10m_LandCover/ImageServer"        in_rst_landcover = "in_rst_landcover"        arcpy.MakeRasterLayer_management(in_raster=esri_lulc, out_rasterlayer=in_rst_landcover, envelope=in_fl_extent                                         )        der_rst_step1a = "step1a.tif"        arcpy.management.Clip(in_raster=in_rst_landcover, rectangle="", out_raster=der_rst_step1a, in_template_dataset=in_fl_extent, nodata_value='', clipping_geometry="ClippingGeometry", maintain_clipping_extent="NO_MAINTAIN_EXTENT")

Advice on fully automating some analysis

We have a regular piece of site screening analysis we do which is partially automated currently

For the GIS analysis side of things, I have a modelbuilder which I run in ArcGIS Pro. That runs a bunch of GP tools (clip, dissolve, calculate field etc), then appends some data to a few different web layers in ArcGIS Online. It also exports all the attribute data to excel.

The rest of the (more commercial) analysis is done in excel. I have a vba script which creates a new version of a blank spreadsheet created by my colleague and inputs the attribute data from the GIS exports. Excel then does a bunch of calculations which are based around commercial viability.

I've got a vision of a fully automated system that removes any need for excel. I'd need for non arcgis pro users to be able to update parameters relating to things like costing used in the analysis. They could be taught to use arcgis online. Ideally I'd also like someone who is not me to be able to press run on this (therefore ideally doesn't involve interfacing directly with pro).

I'm envisaging some kind of system in ArcGIS Online which uses a python notebook and references a bunch of layers/tables in ArcGIS Online? Or do you think it could be run remotely in pro to avoid needing to use credits? In either of those scenarios, how would I let users update the parameters? The 'input' to the model is a polygon feature and I'm really unsure how that will work without pro. Often we are sent a shapefile, sometimes I draw it from a PDF.

Keen to hear anyone's thoughts on this/if anyone has done any similar automation work or even if anyone has any blogs or videos they would recommend on this topic.

Best method to create labels for road names in ArcGIS Pro?

For a series of maps I'm making, I need the roads to have their names displayed. However, the labels included with the default basemaps in Pro don't really work for my purposes (they don't stand out enough and not every road is labeled at certain scales). I think the label tool in Pro is likely my best bet, but I don't know how to modify the labels from the default settings; so I was hoping might be able to provide some assistance with it or an alternative.

What does "Common frequency offset" plot means in gnss raw measurements?

I'm using Google's MATLAB code to analyze raw gnss measurement made with gnsslogger android app. In plots, there is one in particular that I don't understand the meaning, which is "Common frequency offset" plot. At first I thought it was how much the "Common bias clock offset" was varying, but as you can see, when this latter gets a spike, the "Common frequency offset" doesn't change much. So what is the meaning? I searched everywhere but haven't found anyhting. Has Doppler effect something to do with it?

Is there any open source BI Tool that handles PostGIS and WFS

So I have the situation that I am creating a data warehouse with Postgres and the spatial data transformation logic happens in PostGIS using dbt. Now I have the use case of needing to visualize all kind of KPIs in a BI tool and I would love to have a open source tool in which I also be able to create my own custom visualization using libraries like d3.js. However, when I take a look in bi tools like Grafana or Apache Superset it seems that spatial data handling is not much supported outside of basic lon/lat point visualization. I would like to be able to add WFS layers as well as PostGIS data directly in the BI tool. Is there any open source software that would be able to do that? Or did somebody actually implemented it using Superset or Grafana?

Help with Project for GIS Class

For my final project in my class I am doing a spatial analysis of Suffolk County, NY to determine an optimal location of a new solar field. I am a bit lost at the moment and am unsure what layers to start out with. I think DEM, land use, and current solar field locations are a good starting point but am open to any advice. Any advice would be greatly appreciated. Thank you for reading!
