Run through of the Historic Maps section
The Historic Maps section is intended to be a fast and easy way to view a variety of datasets on a number of different area maps. Below is a description of the screens which you will use during the process:-
1. Map and Data selection screen
The map and data selection screen contains three elements, that of the selection of the data, then the area, then the month of the data you wish to see.
Step 1. Select A Map Template - This box is essentially asking you to choose which district you would like to view, then in brackets the way that area is displayed - be it by Ward, Neighbourhood Community etc. You will notice that as you scroll down the same areas are available with different types of geographies in them, and this is to cater to all partnership requirements.
Step 2. Select a Profile - Once you have followed Step 1, the 'Profile' is the type of data you want to view in that area - it may be BCS crime, Antisocial Behaviour, etc. In brackets is the relevant month for the piece of data you would like to view. The drop down box entitled 'Categories' is a way of filtering out what type of data you can see in the box below, to make it clearer. However, if you leave this as 'Show All Profiles', all types of data available for the areay you picked in Step 1 will be displayed.
Clicking 'View Map' following these steps will take you to the next screen which will directly display the combination of data, geography area and time period you have defined above.
2. The Map Page
Singlepoint maps use a browser plugin called 'Adobe SVG', which stands for Scalable Vector Graphics. This allows you to click on the map to zoom in, and not have the picture become pixellated, or 'blocky'. It also allows you to move the map around smoothly, as opposed to the page reloading each time you move to view a different area. The following elements can be seen in an Historic map:- (please note that not all components will appear in all maps)
|
Map Legend - The legend gives the person seeing the map a context for the information; what does a darker or light blue mean in regards to the data i've chosen? The legend changes dependent upon the Legend Class Selector and the data viewed. Moving your cursor over the different sections of the legend will highlight those areas on the map which are applicable to that range of data, and vice versa.
|
|
Data Selector - The Data selector changes the currently viewed data as displayed in both the legend and the map. The number of datasets viewable at any one time is determined by the amount entered by an analyst into a map, or the number available to Singlepoint from practitioners. Use the drop down and select the data you would like to see.
|
|
Legend Class Selector - This drop down box enables you to change how the thematic, or range of data is displayed on both the map and the corresponding map legend. For example, an equal range selection will use the number of classes in the legend and split them equally as a percentage (5 classes with an equal range will result in a 20%, 40%, 60%, 80%, 100% ranged legend).
|
|
Legend Number selector - The Number selector will let you choose how many ways you would like to split the data, so a higher number will result in a larger number of splits and a larger legend, whereas a smaller number will result in increased counts or range for that particular legend class. It is best to experiment with the number and class selector to best represent the data in the map you are seeing.
|
|
Map Controls - The map controls provide a visual representation of how to move around the map and manipulate it. They are fairly self explanatory, however it should be noted that you do not necessarily need the map controls to move the map - clicking with the left and right mouse buttons over the map will zoom it in and out, whereas holding down the left mouse button and dragging will move the map around.
|
|
Layer Control - The Layer control allows you to turn specific boundaries on or off, depending on which you believe to be most important to your view. Therefore, you could turn the boundary layer off if you would like to see just the background mapping, or turn point layers on that may not display when you first load the map.
