I recommend "GIS Cloud" services.
​
GIS Cloud is a spearate business entity and GIS Vendor, and has no contract arrangement with my consulting services.
​
GIS Cloud is a next generation platform for apps that manage location information.
​
I will work with this vendor to set up your web based needs.
​
Their website states:
"The mission of GIS Cloud is not only to supplement desktop solutions, but extend and enrich their capabilities through the potential the Internet provides. It is a more accessible way of visualizing, analyzing and sharing geospatial data, provided as software as a service, but also available free of charge.
Emphasis is on collaboration between colleagues or fellow GIS Cloud users, easy access to data regardless of user’s location and giving a chance to quickly and easily publish maps on the web, share anywhere in the world or use GIS platform to build geo and location aware apps."
