Topographical Map available to order with OS MasterMap®

Download your topographical map


Our topographical map consists of contour lines that depict elevation changes at 1m intervals. It offers a precise and detailed representation of the land's topography, illustrating the variations in terrain across England, Wales, and a large part of Scotland. Generated from LIDAR surveys, our topographic mapping is integrated as an extra layer into OS MasterMap® in CAD format (DWG/DXF) suitable for AutoCAD. LIDAR technology accurately measures surface elevations, facilitating the creation of comprehensive and precise topographic datasets. The inclusion of a topographic map enhances the utility of OS MasterMap® by providing valuable information for diverse applications such as urban planning, infrastructure development, flood risk assessment, environmental analysis and structural stability design.

What is a topographical map?
A topographical map is a detailed representation of the Earth’s surface, emphasising elevation contours and natural features. It contains quantitative data about elevations, slopes, and landforms, making it useful for navigation, outdoor activities, scientific study, and land management.

What is the difference between a topographic map and a regular map?
A topographic map contains detailed information about an area's elevation, geography, and natural features, as well as contour lines that depict height changes. In contrast, a regular map emphasises boundaries, cities, roads, and political divisions rather than elevation or distinctive geographical features.

What topography means?
Topography refers to the physical characteristics of a specific place or region, particularly the land's surface. It is the organisation of natural and man-made physical features such as mountains, valleys, rivers, forests, highways, and structures. To effectively depict the spatial relationships between these features, topography frequently includes measuring and mapping them. Topographic maps, for example, show precise depictions of terrain elevation, contours, and other features to help with navigation, urban planning, resource management, and other tasks.

What is on a topographic map?
A topographic map depicts an area's height, geography, and natural features in great detail. It incorporates contour lines to indicate height changes, as well as information like drainage, forest cover, highways, and population density. (link to:

How do I get topography lines on Google Maps?

What does the term "topography" mean?
Topography refers to the surface features of a particular area, including its elevation, terrain, and landmarks, as depicted on a topographical map.

How do I make my own topographic map?
You can make your own topographical map using our 1m contours layer.

How do you show contour lines?
Contour lines are typically shown on a topography map as curved lines that connect points of equal elevation above or below a reference point, such as sea level. These lines illustrate the shape and steepness of the terrain, with closely spaced lines indicating steep slopes and more gradual changes in elevation represented by widely spaced lines.

Where can I download free topographic maps?
On our website, you can download 1m contour maps as an additional layer to OS MasterMap® in DWG and DXF formats.

What is the topography of England?
England's topography includes rolling hills, flat plains, coastal areas, and upland regions, with notable features like the Pennines and the Lake District. Topographical maps show these diverse landscapes, aiding urban development and land management.

What are the uses of topographical maps?
Topographical maps serve various purposes, including aiding in navigation, land planning, resource management, and outdoor recreation. They provide detailed information about the terrain, elevation, natural features, and man-made structures, assisting architects, planners, surveyors, and researchers in understanding the landscape accurately.

Is Google Maps a topographic map?
No, Google Maps is not primarily a topographic map. While it does provide some terrain features and elevation data through its "Terrain" view option, it primarily focuses on road networks, points of interest, and satellite imagery for navigation and location services. You can get accurate topographical mapping through our website.

MasterMap’s Different Uses

The Telecoms Surveyor

‘I use MapServe to download the Ordnance Survey Mastermap in CAD format based around the mast site. I also use the preview maps and aerial photography on the site to establish access points for on-site visits.’

The Architect

‘I was previously with Promap but I switched to MapServe which is simple, quick and clear compared to the rest of the providers.’ I mainly order OS MasterMap in DWG format.

The Town Planner

‘I use MapServe's mapping service to download the OS Mastermap in DWG format based around the mast site. I also use the preview maps and aerial photography on the site to establish access points for on-site visits.’

The Transport Planning Consultant

‘I mainly use Mastermap in coloured and black and white DWG formats. I need mapping that covers ± 300 m from the site that I then upload to AutoCAD in order to create the appropriate plans.’

The Arboricultural Consultant

‘I use my integrated tree software to plot the trees and its positions and then I create different layers using the Ordnance Survey MasterMap on AutoCAD to create the reports. The plans that I get from MapServe work in correspondence with the reports that I write to my clients.’
