For the purpose of this tutorial we have created simple map in GIS Cloud that is made of US Census data and that displays population growth trends.
In this tutorial we will cover following steps:
- upload data to GIS Cloud
- style it
- publish it on Google Maps
Upload data to GIS Cloud
For the purpose of this tutorial we will overlay part of US Census data and render it according to parameters like population trends etc. We got this data in ESRI Shapefile format. We can upload it through GIS Cloud file manager.
After the data is uploaded to GIS Cloud we can add it in our map.
Bellow the map we can see some of the attributes that are associated with every object on the map. We will now make a simple coloring that will compare population growth trend from 2000 to 2003. We will color regions in green if there is population growth and in red if there is decline. This can be easily done by configuring layer properties:
Now the map looks like this:
We can see how polygons have been colored according to expressions that we entered in the layer properties.
Now we will publish this map on Google Maps. To make an easy embed we can use Publish wizards in GIS Cloud.
