Submitting Data
General
A number of items may be needed such as tree
survey schedule, CAD topographical drawing, proposed drawings etc. These
can be sent to me by post or by email. Completed drawings and other
documents are returned in digital format by email in
whatever format is required.
Survey Schedule
The tree survey schedule (list) can be supplied as an Excel, Word,
Text (.txt) file or as an ArborCAD file. I can also process paper
listings (at extra cost).
Each tree entry must supply the necessary data required for the works
you require. So for example, if you need a BS5837 TCP drawing I would need to
know the trees tag (or ID) number, its diameter, its height, its canopy
spreads, its category code and how many stems it has below 1.5m (so I
can calculate the correct RPA area). If you also have ultimate
canopy/height values these would allow additional data to be drawn.
However, if I am just carrying out shadow analysis then only canopy
spreads and height are really relevant.
CAD Drawing
To carry out any CAD work I will need a drawing supplied in digital
form as either a DXF or preferably an AutoCAD DWG format.
I understand that some architects have yet to enter the digital world
and will only supply a paper plan; in exceptional circumstances I can
use a scanned plan but the final results would not be anywhere near as
good as a proper digital file.
Additionally its not unusual to be supplied with an Ordnance Survey (OS)
base plan; although this would be in digital format, it would still lack
any level data and other important features. Again this can be used if
necessary.
Drawings would be returned by email in a digital format as a DWG, DXF or
PDF file.
If I need to plot tree positions I would need to know their locations so
I would need to be supplied with either their true X/Y positions as a
digital file or be supplied with a paper plan with their locations
marked upon it (these would normally use the centres of plotted trees
shown on the topographical but where these are missing may use a plot by
eye position or include measurements from adjacent structures). Such
plans can be posted or scanned/emailed to me.
