Hence, this method of aerial photograph is also often referred to as overhead aerial photograph. from a ground level perspective. The use of aerial photography to assess and map landscape change is a crucial element of ecosystem management.Aerial photographs are ideal for mapping small ecosystems and fine-scale landscape features, such as riparian areas or individual trees (Fensham and Fairfax 2002, Tuominen and Pekkarinen 2005), because they often possess a high level of spatial and radiometric (tonal) detail.

Both are used in military for techniques 4. all form four past paper history of South Africa PHYSICAL GEOGRAPHY history of africa Sonar systems on ships can be used to create images of the ocean floor without needing to travel to the bottom of the ocean. It's very easy to just knock out' the odd quick sketch. Since the scale of ground photograph is difficult to measure then it is difficult to obtain quantitative measurement such as measurement of area and distance from the photograph, Ground photograph focuses on items on the foreground the far items on the middle ground or back ground may be out of focus and blurred. A camera is basic equipment used in taking photographs and developing them on special paper known as film. But, film is generally a better choice for black-and-white photography.

Images allow participants to describe life experiences more transparently, allowing the interviewee to overcome the fatigue and repetition of conventional interviews and favouring a more active role in the production of information. Some of the advantages include it is cheap to produce, shows the landscape in great detail, and is the most common type of photography. Digital photography has progressively increased the resolution of its cameras and images, but they're still based on single-unit pixels. Both show the physical and relief features on the earth 5. For example, an increase in spatial resolution is typically associated with a decrease in spectral resolution, and vice versa. Management of water resource in Singapore.

The IFOV is essentially the ground area through which the sensor is receiving the electromagnetic radiation signal and is determined by height and angle of the imaging platform. The scale of ground photograph decrease from foreground to background therefore it is difficult to determine the scale of the photograph which can also lead to difficulty in determining the area or size of objects in the photograph. whole area. population studies Less detail in the foreground A high oblique photograph features Visual methodologies are used to understand and interpret images (Barbour, 2014) and include photography, film, video, painting, drawing, collage, sculpture, artwork, graffiti, advertising, and cartoons.Visual methodologies are a new and novel approach to qualitative research derived from traditional ethnography methods used in anthropology and sociology.

If the proportions of the sub-sets are known, it can generate results which are more representative of the whole population. Landsat-7, for example, maintains 8-bit resolution for its bands and can therefore record values for each pixel that range from 0 to 255. kcse resources Knowing the speed of the emitted signal, the time delay from the original emission to the return can be used to calculate the distance to the feature. It shows the landscape in great detail. Also one which is safely and easily accessible and which gives a clear, unobstructed view which includes everything you want to get in, Consider the composition of the shot, what is it that you want to emphasise in the photograph, Ensure that you know how to get the best performance from the camera you are using, Make notes in a log book or field diary: this should include the time, date, location, direction of view and weather conditions for example, Poor weather conditions can make it difficult to get decent shots, There may be some difficulties in accessing suitable, safe sites from which to get the desired pictures, The purpose of the photograph should be clear and linked to the aims and write-up of the study, poorly linked or explained photographs can actually devalue a study, Consider the time element of developing or manipulating a photograph, Using field sketches and photographs within an investigation, Photo editing software can be used to enhance, crop, label and annotate digital shots.
