Style Defination

After the Data Input step, you have inputted the data into database, now you need define the style for each layer, in order to make your outputted map looks more beautiful and professional.

Display Range between Scale:

Range value calculation: for example, a map to be displayed covers a 2-degree by 1-degree area in the EPSG:4326 (WGS-1984) coordinate system.
The linear size of this area for conversion to scales would be considered to be: 222638.9816 meters (m). So, the map extent would be approximately 222639 x 111319 meters linear distance for the purpose of calculating the scale. If the image size for the map is 600 x 300 pixels, then the standard scale value for the map would be: 222638.9816m / 600 pixels / 0.00028m per pixel = 1325226.19.
This calculation is based on a standardized rendering pixel size of 28mm x 28mm. All most of all computer monitors are using this standard pixel size.
If your clients pixel size does not match those values, you will need to change the calculation. Please refer to the OGC SLD (Styled Layer Descriptor) specification for details.

For Point Geometry:

You can choose different point displaying style.

For Text :

For LineString geometry:

In most case, DO NOT fill LineString Geometry, please leave the default value of the Fill Color to -1 (transparent). Unless you know what you are doing, otherwise the outputted map will be displayed out of your thinking.
For example, in your data the building was stored as Linestring(It should be stored as Polygon geometry mostly), but it looks ugly and incomplete if it's path is not closed.

In such case, you can set the fill colour for the building and the map will like this.

For Polygon Geometry:

For Image:

After finish defining the styles, go on create metadata.


The Opercity option can be used to decorate the geometries in SVG image.
