Other maps
There are other types of map that provide a representation of the landscape.
Sketch maps
Sketch maps are simple drawings of the landscape. They show things that are sometimes hidden in photographs or maps, eg the impact of tourists on a landscape.

Photographs
Photographs can be taken from different locations and can be used in conjunction with maps to present fieldwork findings
- Ground photographs - these can be taken on fieldwork, using a camera or mobile device. They need to be annotated to show any features.
- Aerial photographs - these are usually taken from an aeroplane or drone. They cover a wider area than ground photographs so they are useful in showing spatialRelating to space or how things are spread out. patterns.
- Satellite images - these are high-resolutionThe fineness of detail that can be seen in an image - the higher the resolution of an image, the more detail it holds. In computing terms, resolution is measured in dots per inch (dpi). photographs taken from satelliteBody that orbits a planet. For example, the Moon is a natural satellite of the Earth but communication satellites are artificial satellites of the Earth. in space. They show a very wide area, but in less detail than close-up images.
Annotating maps and photographs
Annotations are detailed labels with an explanation of what is shown. They are important because they allow geographers to interpret and compare maps and photographs. Annotations can focus on physical or human features and they usually include key terms.
Synoptic charts
A synoptic chart is any map that summarises atmospheric conditions (temperature, precipitation, wind speed and direction, atmospheric pressure and cloud coverage) over a wide area at a given time. They display an overview of the weather conditions observed from many different weather stations, aeroplanes, balloons and satellites.
By collating the information over a wide area, meteorologists can observe the behaviour and movement of weather formations that might affect their local area in the future. This allows meteorologists to make more accurate weather forecasts. Charts are updated at least every six hours.
There are many different types of weather map, all drawn using internationally agreed standards and using accepted symbols.
