Introduction to Maps

• What is a map?

• Types of maps

• Brief guide to using maps as sources

• Early mapping for legal issues…

Map (maep) n.

• a diagrammatic representation of the earth’s surface or part of it, showing the geographical distributions, positions etc. of features such as roads, towns, relief, rainfall, etc.

• a map like drawing of anything

Formats

• Paper – Atlases– Sheets

• Single• Multi part• Series

• Microfilm• Digital

– Raster– Vector

Raster v vector

• “A raster image is a computerized picture. If you have a raster image file, you can overlay additional … data, such as street maps or customer locations, on top of the image. Raster images consist of rows of tiny dots. In contrast, objects in vector images contain coordinate based data structures represented by x and y coordinates.”

Beware…

• Dates• Accuracy• Purpose (e.g. plans)• Often not designed to be used in isolation

• Require accompanying terriers or documents• (there may not be a key…)

• Bias • the cartographers choices (what to include?)• political influence• your own bias

• Sheet referencing by County:OS 6” to the mile / 1:10,560 Aberdeenshire VIII (4 x 6 miles)OS 6” to the mile / 1:10,560 Aberdeenshire IXOS 6” to the mile / 1:10,560 Aberdeenshire X

OS 25” to the mile / 1:2,500 Aberdeenshire VIII.1-16 OS 25” to the mile / 1:2,500 Aberdeenshire VIII.4 (1 mile x 1.5 miles)

• Revision by county - all or part of the county revised at particular points in time.

Section 2 - Ordnance SurveyNational Grid

• Davidson Committee from late 1930s recommended the recasting onto a new projection for the whole of Great Britain, the National Grid: a Transverse Mercator projection with a central North-South meridian, and a point of origin based west of the Scilly Isles. New metric grid based on 100 Km squares.

Section 2 - Ordnance Survey“Ordnance Survey is Great Britain's national mapping agency, providing the most accurate and up-to-date geographic data, relied

on by government, business and individuals.”

Some recent issues:

• Income generation and cost recovery• Greater imbalances of surveying• Greater costs of large-scale mapping• Greater concern over copyright and IPR• Focus on core mapping - provision contracted out to Partners and

Mapping and Data Centres. Greater liberty to vary prices locally around core parameters.

• Disposal of historic mapping

Choose a location using one of the criteria provided.

The system will then search for that location.

The location will be displayed on screen.

If necessary, you can pan around the map to find the exact location.

Choose the type of mapping you want. 1:2500 scale or larger is available as Superplan or Siteplan; 1:5000 or 1:10000 scale is available as Landplan.

Siteplan Option

Siteplan is available in a variety of options.

In order to be able to find your property, you may need to pan around and either zoom in or change the scale number.

Once you have found your property, click on it with the cursor.

Zoom out to check the area covered by the Siteplan. You are now ready to progress with the order.

Superplan Option

Superplan is available in several variations. ‘Customised’ allows you to specify exact plot size and a range of additions.

You can specify centre co-ordinates and dimensions or use the cursor to draw a box to enclose the required area.

The mapping can be displayed at a different scale by zooming in or changing the scale.

If a customised product has been chosen, a feature box can be added.

Alternatively, a circle could be chosen.

A polygon can be used to define an irregular area. Different line and infill colours are available in every case.

Before printing, certain features can be added to maps, e.g. highlighted buildings.

A title can be added, or the printed scale can be set. You can even print the map reversed on film for architect’s use.

Landplan Option

Landplan is available in a variety of options

In order to be able to find your specific area, you may need to zoom in and pan around

If you have chosen ‘customised’, you can then draw the area you require with the cursor.

Alternatively, you can specify exact dimensions for the box and/or centre co-ordinates

Zoom out to check the area covered by the Landplan, in this case 3km by 3km.

A title can be added, or the printed scale can be set. You can even print the map in black and white.

All Options

Finally, the order is given a total price and can be given a name.

• Under fair dealing, OS allow “limited reproduction” (up to 4 identical A4-sized copies) of in copyright maps for non-commercial research or private study or Parliamentary or Judicial Proceedings

Licences• OS have a wide range of licences for using in-copyright mapping,

depending upon who you are, and what you wish to do with their mapping:– Paper Map Copying Licence– Publishing Licence– Framework Partner Licence– Internet Licence– Superseded Mapping Licence

• Libraries also have rights over the onward publication of their maps. NLS requests that permission be requested for all publications of our maps. Usually there is no charge for non-commercial reproduction.

• NLS also has an annual permission licence (£100 per annum) allowing unlimited copying of NLS maps for unpublished reports for clients

Ordnance Survey Superseded Mapping Licence

Digital MappingRaster Images.

• Any historical mapping• Scanned maps from desktop or large-format scanners• Smaller-scale digital data from OS• Typical formats: TIFF, PNG, BNP, GIF• Usable by any picture editing software - Imaging, Paint, Photoshop, Illustrator. Also usable

by Geographical Information System (GIS) software• Can alter basic image parameters - crop, and add features as extra layers on top of base

raster image• Relatively available and easy to use software.

Vector Images• Modern OS mapping• Typical formats: GML, DXF, NTF, ArcGIS Shapefile, MapInfo MID/MIF• Usable by any Geographical Information System (GIS) software• All topographic features coded into layers and presentation of features can be customised.• Much greater flexibility over presentation of image and integration with other data.• Greater complexity in availability and use of software.
