Desktop ArcGIS Instructions
Typical screen with basemap layer and points (white circles) for trees and tubes
If you click on a point this screen opens:
By clicking on the “Edit” you can edit fields at each point:
This opens screen of editable and non-editable fields.
ID, Address, Street, SPP (species), Park and GTM Type – these are there for location and identification reference.
Editor Name(s) – Include your name or email address (first names are okay if you are concerned about privacy)
Date Last Visited – this only lets you input the date when you visited the site
Alive? (Y/N) – just enter “Y” or “N”
- Trees that are alive will appear as white points with a black outline
- Trees that are dead will appear as black points with a white out line.
- Trees that have no data in this field will appear as red points with a black outline.
- Once this field is changed to Y or N the map will automatically update the symbol to allow tracking of work performed.
- Carefully enter only a Y or N to ensure a correct symbol reassignment.
- If the correct value isn’t entered the point will stay red.
Height (cm) – measure the height from the soil line to the top of the terminal bud in centimeters to the nearest 0.5cm
Maintenance Required – very briefly describe maintenance needs (e.g. tube missing, net missing, tree dead?, stake broken, etc.)
If there is date data in this field you can delete it:
Work Performed – enter any work you performed during your visit (e.g. mulched, watered, new net, new Stretch Locks, etc.)
Now you can close the edit window (below left) and your data is added to the database. Be careful to avoid deleting the point (below right):
All data is updated in real-time so your edits are applied immediately!
Mobile ArcGIS Instructions
First, download the ArcGIS app for your mobile device (available for iOS, Android and Windows Mobile)
Use this one!
DON’T use this one!
Once installed, search for “Minneapolis Grow Tubes” – you don’t need to log in to access the map!
The interface for mobile devices is very similar to the desktop version but can vary greatly between mobile operating systems. You use pinch, swipe, tap and tap hold functions to access map features and points.
The mobile interface can take some practice so you might want to use the desktop first while you’re making your first foray into this system.
If you have any questions, please send me an email!
THANKS and Good Luck!
