• Not only the digital form of the contents of a map ready to be used with a computer.
• No need for segmentation, the elements are of real size, has accurate fitting, has topology, often uses layers and objects.
• Primary Data Obtaining Methods– Measurements (GPS)– Existing Reports
Mostly vector data are obtained from primary data obtaining methods.• From Secondary Sources
– By digitalization, adding automatic or manual vectorization.In the case of georeferencing and vectorization in secondary methods,
the result is also a vector map. If a secondary data collection (scanning) is not followed by vectorization, the result is a digital raster map.

• With the help of hybrid systems, raster and vector data can be used together. – Vector, raster and attribute data are stored separately, in
the most suitable way for the model.– The operations are carried out by these systems in the
model that is most suitable for the operation in question.– The systems apply a wide variety of vector-raster
transformations before and after the operations.– The GoogleMaps service is based on a hybrid data model.

• GPS measurement gives the height above the ellipsoid (h). When calculating height above sea level(H), geoidundulation has to be taken into consideration.
• Geoidundulation is the separation between the equipotential surface that represents a mean ocean surface and a reference ellipsoid (h=H+N, where N is the value of geoindundulation of the point).
• Geoid: the surface of oceans and seas, if connected by small canals under the land(Listing 1873)

• Remote Sensing– With the help of remote sensing, objects can be examined that
are not in a direct connection with the sensor.– In a narrow sense, the concept of remote sensing is usually used
for aerial and space images. In a wider sense, it can also be defined for eg. remote measurements or medical applications.
– Remote sensing is the acquisition of information about an object or phenomenon, without making physical contact with the object. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans) by means of propagated signals (e.g. electromagnetic radiation emitted from aircraft or satellites).

• Chlorophyl absorbs the energy of the wavelengths between 0.45 and 0.67 µm,mostly blue and red colours, thus the colour of the healthy plant is green.
• In an unhealthy plant, the yellow colour together with the green can be caused by red reflection caused by chlorophyl decrease.
• Reflection within the range 0.7 and 1.3 µm highly depends on leaf structure (sort specific), and dramatically increases.
• Effect of stratification, water occlusion bands above 1.3 µm.• Above 1.3 µm, reflection is inversely proportional to the
whole water content of the leaf.

Relation database model – Theoretical basis
• In 1970 Dr. Edgar F. Codd (IBM) create the Relation Database Model.
• The data model describes the various types of data, their relation, connections, and their privacy procedures.
• The collected data are logically separate entity types, entities (table). Determine that the individual entities, whereas we can clearly identify, and also what additional features (attributes).

Definition• Bioinformatics derives knowledge from computer
analysis of biological data. These can consist of the information stored in the genetic code, but also experimental results from various sources, patient statistics, and scientific literature. Research in bioinformatics includes method development for storage, retrieval, and analysis of the data. Bioinformatics is a rapidly developing branch of biology and is highly interdisciplinary, using techniques and concepts from informatics, statistics, mathematics, chemistry, biochemistry, physics, and linguistics. It has many practical applications in different areas of biology and medicine.

Basics: Structure of the DNA• Double helix, in which nucleotide bases on the two strands
are connected by Hydrogene bonds: A:T - 2, G:C – 3 H-bonds • Base pairing: complemeter nucleotide bases within the long
polymer are: A:T and G:C• replication, • Genetic code- isn’t monotone • Two helical chains each coiled round the same axis, and each
with a pitch of 34 Ångströms (3.4 nanometres) and a radius of 10 Ångströms
• These two strands run in opposite directions to each other and are therefore anti-parallel, 5′ (five prime) and 3′(three prime) ends
• It containes four bases: adenine (A), cytosine (C), guanine (G), thymine (T)

difference of the aligned sequences. – In case of ortholog sequences: differences of
sequences from different species arises from the mutations collected during their different evolution.
– Number of mutations, namely the rate of the difference between the sequences is connected to the evolutionary distance between the two species: the longer ago the two species separated, the higher sequence difference occur within their ortholog genes.

Definition of genome?
• The genome: „The genome is the entirety of an organism's hereditary information. It is encoded either in DNA or, for many types of virus, in RNA. The genome includes both the genes and the non-coding sequences of the DNA/RNA.” (Wikipedia)

Genomics is the discipline of Genome
• Genomics: encompasses a broader scope of scientific inquiry associated technologies than when genomics was initially considered. A genome is the sum total of all an individual organism's genes. Thus, genomics is the study of all the genes of a cell, or tissue, at the DNA (genotype), mRNA (transcriptome), or protein (proteome) levels.– Functional genomics: attempts to make use of the
vast wealth of data produced by genomic projects – Structural genomics: attempts to determine the
structure of every protein encoded by the genome
