Street Tree Inventory
(using GPS coordinates)
These links will provide you information on developing a Street Tree Inventory
using GPS coordinates. We believe the best approach
to conducting and managing a Street Tree Inventory is to reference
their location not only with a physical address/area but also it's GPS
coordinates. Even with low-end low-cost hand-held GPS units, you
can get close enough to the tree to determine which one it is in
most cases, all you have to do is look up. These techniques reference our Arboriculture
Inventory software system but can be altered to use your Street
Tree Inventory system.
Tools & Techniques
We have developed a couple of tools and
techniques to help up enter data and reduce errors. These tools
and techniques can be duplicated or modified to fit your needs.
Pictures / Images
Digital Camera with optical zoom that automatically rotates images, since most pictures will
be taken in the portrait mode (taller) than taken in the landscape mode
(wider). The image resolution should at least be 2 mega-pixels for decent images,
use higher resolution when needed. Image storage should be in
on a Secure Digital (SD), Secure Digital High
Capacity (SDHC), Memory Stick (MS), CompactFlash (CF), or some other removable
media which can easily be read by computer. Having a Zoom feature will
help with framing the picture without having to physically move back and forth to get
the desired picture.
The Global Positioning System (GPS) is a Global
Navigation Satellite System (GNSS) developed by the United States
Department of Defense.
