33. Dashboard Challenges
• Getting data from areas lacking cell signal.
• Arcgis.com webmap limitations
• Poor performance on IE
• Upload max 2MB or 1,000 features
• Doesn’t allow downloading of zipped shp files
from webmap
• Building community of users
• Long-term hosting of website

what the
new
imagery of
that spot
looks like!
