mapping tree locations

[stihllearning]

hi all. visited a new client today with loads of veteran trees in a piece of parkland open to the public, its a huge deadwooding project.but first things first i have to do a hazardous tree assesment, so all need to be numbered and mapped and was hoping that with species, number and gps reading someone could help me with mapping there location,i'm sure there's an autocad bolt on for the job but its something i know little about. any sugestions thanks

I've been working with a pda (hand held / palm top call it what you want!) that the maps get loaded on to. The gps then bluetooths the location to it on request and marks the spot, these are then checked against something known. The check is due to the gps accuracy being in the 10's of metres sometimes!.

 

I've also heard of people changing a setting on the autocad map, so that the co-ordinates on the map relate to the national / OS grid. This means that you can put in the GPS figures to mark a point.

 

Another option is a centrally located laser range finder, with a compass facitity. Known gps point for laser, then distance and direction for each tree.

 

All probably involve spending ££££!

 

Hope it helps

treedave thanks for your reply and thank you for your sugestions.what i was realy hoping for was someone who makes these sort of maps regularly to be able to (with all the info provided by me)make one up for me at a cost . any one out there???

 

 

 

thanks

do you want a 2d map or 3d map?

 

how big is the land?

[stihllearning]

hi 101

 

2d should be fine as for the size of the land ,i'm waiting for a map from the land agent but i reckon no bigger than 2k by 2k

Do you want it so you can open it up in a GIS program or do you just want it as an image you can print off paper maps to scale and hide deferent layers/futures?

 

Can you find it on flashearth? http://www.flashearth.com/?lat=52.500000&lon=-2.0000002&z=9.3&r=0&src=msl

[stihllearning]

evenin,yup can find it on flashearth interesting link thanks.

 

just a paper map realy but i imagine it would be practical to have it linked to a spread sheet to then make later inspections easier

open it up in a GIS program

 

hey up sounds like someone else is involved in computer mapping! how come your using/know about GIS?

It’s a long story, but basically I use to do commercial 3d outsourcing for computer games in my spare time mostly on stuff I had never seen before in the USA like buildings etc were I would have photos of the facades of the building but not necessarily the scale (implied from standard 2m doors etc) or the ground plan, so I use to use high resolution satellite images as a tool for working out the true scale + ground plan from them, then later I moved onto terrains so got involved in DEM’s (3d terrain maps), I have also been using GPS for years as well as digital mapping for my logistics work as is away from the public road in remote places etc, as well as the usual parallel swathing & area worked etc.

Do either of you have any experience with PocketGIS?
