1 is the ruler tool. This allows you to draw a line to measure distances on the map.
2 controls the zoom level for the map.
3 allows you to expand the map interface to full screen. This is helpful when you need to work across a larger area.
4 is the search tool. This allows you to search locations and addresses on the map.
5 allows AHVVA to find your current location. You may be required to give the browser access to your current location for this to work.
6 changes the map into a satellite map view. This may be useful to inspect the area where you want to place markers or paths.
7 changes the map into a road map view. This view is the default view.
8 changes the map to a dark map view. This provides a high-contrast background that can assist in drawing paths and other map elements.
Auto-Path Marker Tool
1. You cannot place an auto-path marker inside a building
2. If you place the auto-path marker inside an area that is far from any nearby roads, the analysis may return a result where the paths “cut” across empty spaces.
3. the path finding algorithm will automatically detect the presence of obstacles such as buildings, bodies of water etc where that data is available.
Manual Path Tool
This is the Manual Path Tool. When using this tool, you can manually draw the path for analysis and AHVVA will only analyse the path that is drawn. This is typically used when a very specific and known path is to be analysed.
There is no limit on the number of paths that can be manually drawn – you can draw as many paths as you require.
Click to add additional points to the path such as turns or corners. When you reach the last point of the path, double-click to conclude the path line.
1. The manual path tool will analyse the path as drawn by the user. It will not detect any obstacles, so if a path is drawn through an obstacle such as a building, it will not detect that building.
Hybrid Path Tool
This is the Extended Path tool. This works like a combination of both the Target Marker and the Single Path tools. The starting point of the Extended Path will be treated like a Target Marker, and all possible paths converging to that starting point will be automatically identified. However, the vehicle will then continue along the rest of the path that was manually drawn.
When using this feature, it is important that you draw a path consisting of more than one (1) point.
Click additional points to designate the entire path.
Please note that you must designate a path that consists of more than two points i.e. it must be at least a straight line.
1. The starting point of the hybrid path is effectively an auto-path marker. This means it must be used with all the limitations of the auto-path marker in mind i.e. it cannot be placed inside a building.
The perimeter tool allows you to analyse an extended area such as the perimeter of a building or site. Users draw a red line which represents the perimeter. The analysis will place auto-path markers every 10 meters across the perimeter line drawn, and auto-path marker on any corners of the perimeter.
Using the perimeter tool is similar to the manual path or hybrid path tools. Click on the starting point to begin the perimeter line, click to insert corners and then double-click to complete the perimeter line.
1. The perimeter tool uses the same automated path finding algorithm as the auto-path marker tool. Therefore the same limitations that apply to the auto-path marker tool also apply to the perimeter tool i.e. the perimeter line cannot be inside of a building or in an area that cannot be accessed by a nearby road.
2. The perimeter tool requires a lot of computation and therefore may not be suitable for use across very large areas or distances.
A blocking element allows you to close off certain roads, paths and streets to exclude them from the analysis. This can be helpful to replicate road closures for example.
Click at the starting point of the blocking shape to begin drawing the blocking element.
Using the polygon tool, draw a shape to cover the area which you wish to block from the analysis. Any roads, paths or streets within the shaded area will not be included in the analysis.
