What does XYit do?
(8.4,15.2)
(5.2,14.2)
(4.6,12.2)
(3.5,9.2)

• It converts data in images into XY values

• Suitable images are maps and plans

• So you can put the XY values in a spreadsheet

• XYit converts the points into their original XY
  values

• It also does the opposite, correctly positioning
  your XY data onto an image, map or plan

3
Suitable images files are...

• Electronic Documents, e.g. from Internet
• Scanned Documents
• Digital Photographs
• The computer Screen itself
• In any of over 40 formats
• including BMP, JPEG, GIF, TIF etc

4
Suitable images are..

• Graphs

• Maps Plans

• Photographs.

5
Graphs

• Financial
• Values of price against date
• E.g. Stock price graph
• Scientific
• X-Y Values
• Engineering
• Linear or Logarithmic Axes

6
Maps Plans

• Site or Survey Plans
• Land maps e.g. UK Ordnance Survey
• Nautical Mercator Charts eg UKHO Admiralty

7
Maps PlansExamples

• Creating Waypoints for a GPS
• Calculating footpath co-ordinates from a map
• Making a Passage Plan from a Nautical Chart
• Creating cable course files from old cable plans
• Finding the position of objects on old maps
• Determining the dimensions (area, perimeter) of
  land plots

8
Aerial Photographs

• Plot sizes / field area
• Find boundary positions
• Field perimeter length
• Position of an isolated object
• Finding the width of entrance

9
Photographic Analysis

• With XYit you can take measurements from a
  photograph of an object in profile ...
• Example 1 Picture of Building -
• Measure dimensions, length of roof etc
• Example 2 Picture of Vehicle-
• Measuring Dimensions, Area, Perimeter etc

How does it work?

• 1. Calibration
• XYit needs to know 3 or more calibration values
  so that it can work out the real values at any
  point
• 2. Data Capture
• Next tell XYit the points which you want to
  convert This can be done manually or
  automatically
• 3. Export
• Save the data to a file or to a spreadsheet

11
Step 1. Image Calibration
(9,90)
(10,100)
(0,100)
(1,80)

• This is very easy
• Either Click the mouse on 3 known points

• And then supply their true values

• Or use 2, 3 or 4 corners

• Then enter into XYit the true values at these
  corners

(8,1)

• From then on, XYit will display real xy
  coordinates
• With maps this is called 'Georeferencing'

Step 2. Data Capture
(8.4,15.2)
(5.2,14.2)
(4.6,12.2)
(3.5,9.2)

• Next tell XYit the points you want to convert
• Either by mouse
• Or it will automatically trace lines for you

• Using the information provided at calibration,
  XYit automatically works out their true values

• You can edit the points, save them or view them
  later

13
Step 3. Data Export

• Finally you can save the data to a file
• Or to the clipboard for transfer to another
  application
• The data is in plain ASCII tab delimited format
