Plotting Shade
To plot shadows you need to know your latitude and the position of True North relative to your site. Once these are known, it is possible using sun charts or computer programs to find the position of the sun for any time of day throughout the year.

In WebShade, ShadeModeller will plot the shade at your site.

WebShade determines your latitude (and from this, your sun angles) when you enter the address of your site.

WebShade’s NorthFinder will assist you to easily and accurately find True North by guiding you to resources in your location. Most of them are websites for mapping authorities or local councils where you can buy a plan for your site showing True North. WebShade has tested these resources to check reliability and delivery times.

Using WebShade, you can accurately predict where your shade will fall at any time of the day and at any time of the year.
