A friend and I have been building, for the first time, a webgis that enables queries and visualizations of data. Our work looks a bit like this:
We used PostgreSQL, Leaflet library, and PHP Zend Framework. These may be different from the website above, but I just use it to give a better sense of the design. We've been in a good shape and are likely to be able to upload the website on internet soon.
I want to know about some hosting services that support PostgresSQL as we have limited experience in this. Affordability is the preference since our work is more a demo at this stage.
