Sketching in Mergin Maps

Sketching in Mergin Maps

I hardly ever do Mergin Maps blog posts. I need to do more. So I've been mapping random things in Chattanooga for OSM - which puts me out with my Bad Elf GPS and Mergin Maps. I don't do nearly enough field work these days. It sort of scratches an itch. It's fun. I'm...

15 years plus a Few Days…….

So I was flooded on linkedin the other day with "Congrats on your work anniversary" and it always makes me feel weird. I was also at a potential client's location a few weeks ago and the comment was made "I heard you died". All the congrats were for 19 years of...

Playing with QGIS 3.44 Solothurn: SQL

It's been a while since I've had the chance to play with a new version of QGIS. The stars have aligned so I'm digging through the changelog and testing some things out. Not that I've been super attentive for a while - BUT I have noticed the DB Manager has been a bit...

TN911: Adding Elevation

The big goal with the TN 911 project is to eliminate steps and still enter good data. I'd like to fill out as much of the database as I could with minimal work from the person putting in data. Hence I've riddled the database with triggers and made drop down lists of...

Tickets: https://www.eventbrite.com/e/introduction-to-mergin-maps-tickets-1387725035939 One of the big questions I get asked on QGIS is "What's the mobile environment like?". Which leads to a whole discussion on Qfield and Mergin Maps. I'm more familiar with Mergin...

I want to ride my bicycle Part 2

I want to ride my bicycle Part 2

Shortly after getting out of the Hospital I fell. I went down hard. It was embarrassing. Probably the worst thing is it took two people to help get me up. One person was pulling me up towards the left and one person was pulling me forward...which wasn't helping my...

Opening a ArcPro Template in QGIS

Opening a ArcPro Template in QGIS

Sometime in 2020, I ordered the ArcGIS Home Program and ran it on some virtual machine I had sitting around. My problem is I have too much fun learning things on the open source side of the house so I didn't use it a lot. As I look back I'm pretty sure I stayed in the...

GRASS and m.cogo

I hate putting in Deed calls. Some of you may call it Metes and Bounds. I usually even utter "Survey" as more of a curse than anything. There's always the Azimuth and Distance plugin but if you check the homepage you will see it's basically on life support or as it's...
