    ID this rope?

    First one, the green line, is a Sterling HTP. Many rope manufacturers nowadays will put a ribbon inside the core of the rope that will have lot/batch number and sometimes info on the manufacturer.

    GIS and Inventory Systems

    I'd honestly just keep it simple and just use the 10-20-30 rule to display diversity... it'll be much easier to digest for whoever you're doing the inventory for and will allow them to do the calculations themselves in the future if they keep their inventory data updated. The Shannon-Weiner and...

    If you use Simpson’s index, I’d recommend using the inverse Simpson index. Instead of a lower number representing greater diversity, the inverse index will be a higher represents a greater diversity. I highly recommend using the 10-20-30 rule with an accompanying bar graph showing the...

    Not really, but there are a few that you could use. The most simple and probably most well known (although not a true index of diversity) is the 10-20-30 rule where in a given inventory there should be no more than 10% of a single species, 20% of single genus, and 30% of a single family...

    GIS and Inventory Systems

    If you're enrolled in a college taking a GIS class, check to see that you don't already have access to the ESRI training website. With that course, you should have access to an ArcMap/ArcGIS Pro license so that you can use the software on your laptop, no point in paying $100 for something you...

    GIS and Inventory Systems

    LiDAR is incredibly useful in urban settings actually... When combined with a multispectral scanner or land use data, they can codify the returns to low, medium, and high vegetation as well as buildings, power lines, etc... which can really help with measuring an urban tree canopy. Then...

    Yeah, there's also the point that if you use drones for hire, you also have to be licensed by the FAA if I remember correctly. If you do want to dive into using drones look into "Photogrammetry" and remote sensing. If you get a drone, get one that can carry a LiDAR sensor.

    GIS and Inventory Systems

    Me personally? No. I do have access to a drone, but I don't bother with it... Other companies? Probably, but I'm not sure to what extent realistically. I would hold off on a drone till you find that it can provide a solution to a need down the road. As you first start out, you'll probably be...

    GIS and Inventory Systems

    Not really, like I said, learn the software and then think about coding, it’s definitely not a requirement. If you’ve had experience with other layer based editing programs like Photoshop, then GIS should come pretty naturally... imagine photoshop but with an excel file attached to each layer...

    GIS and Inventory Systems

    Sounds like you've got it squared away with learning GIS! I would definitely focus your efforts though on learning GIS itself at first, as learning Python alongside it might be quite a bit to handle.... It took me several tries to fully grasp the programming language and begin to use it...

    When people try to do their own treework

    Absolutely, and I don't think anybody would necessarily disagree with that statement (except maybe if you were trying to launch a rocket into space or something). In fact, I'm sure a majority of us on this site are very capable self-learners that can figure something out with relative ease. Hell...

    swing dutchman

    Swing-dutchmans, tapered hinges, plate cuts and all other forms of arboricultural quackery generally don't work as intended and are more of a result of confirmation bias by those that utilize them. Every example I've seen of someone trying out these techniques always notched it in the intended...

    When people try to do their own treework

    IMO this is a much higher level issue with our industry and its perception to the general public. When people have issues with the power in their home, HVAC, gas, etc... really any issue that requires a 'skilled tradesman' is generally not going to be attempted by your average homeowner, why...

    GIS and Inventory Systems

    Standard program is ArcGIS, if you're going to be using any software suite, this is the one to use especially if you plan on doing any sort of intensive GIS work. If you have no- to little experience with GIS but are willing to learn, many community colleges are beginning to offer certificates...
