Trying to create something for mapstory.org It wants it in all one shapefile. So I create a polygons and lines (with time attributes) in qgis 1.8 Then merge them all into one shapefile, how can you save the styles of all those polygons and lines into one .sld, how do you create an sld file that will have the info for all those merged polygons and lines?
You'll want to symbolize your data based on the attributes of the data. In this case it sounds like you'll want a different symbol for each time attribute.
In QGIS you can easily accomplish this by doing this:
- Double click the layer name to open layer properties
- On the Style tab change the dropdown in the upper left from "Single Symbol" to "Categorized".
- Choose the column containing the data you'll be categorizing by.
- Click "Classify"
- You can then click "Save Style" and choose to save your newly created style as an .sld
Not sure if I understand your attempt correctly, but you can not merge polygons and lines into one single shapefile.
