Accuracy of Mapping and Measuring


Streetwise supply Ordnance Survey mapping to the accuracies as supplied by them. These are detailed below.
In addition the Streetwise measuring tools not only incorporate any existing errors from the mapping but are dependent on 4 other factors; namely, relationship to features, cursor placement, pixel size and the calculation used.
Streetwise offer no guarantee as to the accuracy or otherwise of the above. If an exact positional or measurement accuracy is required then a site survey is recommended.



A: Ordnance Survey Detailed Mapping Accuracy


Relative Accuracy

Definition
Relative accuracy is the positional consistency of a data point in relation to other local data points.

Measurable
The comparison of the scaled distance between features measured from the data with the distances measured between the same features on the ground.
This measurable refers to well-defined points in the real world, for example, building corners or fence junctions.
Certain types of features, such as underground features, vegetation and landform limits, can be surveyed to a lesser degree of accuracy.

Conformity
Ordnance Survey has continually sampled data and tested the relative accuracy of well-defined points of detail.
The table below shows the aggregated average results of testing from the last 30 years.
If the distances between well-defined points of detail 60.0m apart were measured in the real world, there is an expectation that 95% would be represented in OS MasterMap by a scaled distance of between 59.2 m and 60.8 m.

Correction
Any reported errors outside the expected range are addressed during the normal update cycle, or earlier if warranted by their impact on customers’ business.

Improvement
Ordnance Survey is improving the positional accuracy of OS MasterMap rural overhaul areas through the Positional accuracy improvement programme –
http://www.ordnancesurvey.co.uk/positional/.

Absolute accuracy

Definition
Absolute accuracy is a measure that indicates how closely the coordinates of a point in the dataset agree with the true coordinates of the same point on the ground in the British National Grid reference system.

Measurable
The comparison between the position recorded in the data and the true position of the feature on the ground.

Conformity
Ordnance Survey has continually sampled data and tested the absolute accuracy of well-defined points of detail. The aggregated average results of this testing over the last 30 years show that the absolute accuracy of existing data is as shown below in table.
Example of absolute error statistic Urban (1:1250)
If the coordinates of a well-defined point of detail in OS MasterMap are compared to their true position, the expectation would be that in 95% of cases they would lie within a circle of radius 1.0 m from the true value.

Correction
Any reported errors are addressed during the normal update cycle, or earlier if warranted by their impact on customers’ business.

Improvement
Ordnance Survey is improving the positional accuracy of rural overhaul (1:2500 scale pre-positional accuracy improvement) OS MasterMap through the Positional accuracy improvement programme –



B: Measuring Accuracy


The accuracy of measurement is also dependent upon:

  1. Relationship to features
    As there is no “snapping” to boundaries and other features the accuracy of selected points is dependent on the use.

  2. Cursor placement
    Measurement is based on the locations specified by the user through mouse clicks. Measurements are therefore limited in accuracy by how carefully the cursor is placed in the map view when the mouse button is clicked.

  3. Pixel size
    The map representation on the screen is, by the nature of the display technology, discretized into pixels. The accuracy is therefore inherently restricted by the size represented by each pixel. The world map size represented by each pixel varies according to the scale at which the map is viewed. As an example, the world size represented by the size of a pixel within the 5ha view is greater than that of the 2ha view.

  4. Calculation
    Basic standard equations are used to calculate the length and area in pixel co-ordinates. The values are then factored by the world size represented by the width of a pixel in the map view on which the points were being specified. The values are then rounded to two decimal places for display purposes.
    The vbscript functions / algorithms for these calculations are, therefore, implemented as follows:
    function measureDist() { var i, d = 0.0; var len = pointCache.length; if (len <= 1) return d; var x1, y1, x2, y2; for (i=1; i<="2)" } 100; 100) * Math.round(a return uxp); uxp="getUnitsXPixel();" a="0.0;" var x1); - (x2 y2) + (y1 y2="pointCache[i].y;" x2="pointCache[i].x;" y1="pointCache[i-1].y;" x1="pointCache[i-1].x;" { i++) i

7. Refund Policy


Streetwise will refund any order which is not of merchantable quality up to 14 days after purchase. For clarity, merchantable quality does not include out of date maps or wrong sizes or scales of maps. No refund will be made for maps which are “fit for purpose”. Streetwise allow a preview of the map site and size prior to purchase, therefore by agreeing to purchase the map, customers are agreeing that the map seen is suitable for their purposes. Refunds will be made within 24 hours of a confirmation email of an agreed refund. Any maps refunded will no longer be licenced for use, therefore their use would constitute a breach of Crown Copyright, which is a criminal offence.
