Basics of geodesy
Geodesy is the science of measuring and understanding the Earth. It involves determining the size, shape, and gravitational and magnetic fields of the Earth. Geodesy uses measurements from satellites, GPS, and fieldwork to model the Earth as a flattened ellipsoid with parameters like semi-major and semi-minor axes. An accurate mathematical model of the ellipsoid is needed for scientific and practical applications involving the representation of the Earth's shape.
Map Projections ―concepts, classes and usage
The document discusses different types of map projections used to represent the spherical Earth on a flat surface. It begins by explaining that map projections transform 3D global coordinates to 2D planar coordinates, which necessarily distorts properties like distances, angles, or areas. It then covers key projection categories (cylindrical, conic, azimuthal), their characteristic properties and examples. Specific projections discussed include Mercator, UTM, and polar stereographic. The document emphasizes that the appropriate projection depends on the map's intended use and which distortions are least important. It encourages map users to understand basic projection concepts.
Map Projection
Projecting maps involves converting the spherical earth into a flat plane, which inevitably causes some distortion of properties like angles, areas, directions, and shapes. There are three main types of map projections - cylindrical, conical, and planar - which involve wrapping a lighted globe onto different geometric surfaces like a cylinder, cone, or flat plane. The Mercator projection specifically was created to aid navigation by representing lines of constant bearing as straight lines, though it distorts the relative sizes of land areas farther from the equator. The Universal Transverse Mercator (UTM) system divides the earth into zones and uses the Mercator projection locally in each to assign Cartesian coordinates.

Historical Development of Photogrammetry
Photogrammetry is the science of obtaining information about physical objects through photographs, without needing direct contact. It involves measuring and analyzing captured images. The name comes from Greek roots meaning "light", "drawing", and "to measure". Key developments included using photography for mapmaking in the 1840s-1850s, the photogrammetric stereoplotter in the 1890s, and aerial photography from balloons and planes in the 1860s-1900s, advancing the field into the digital era.

Aerial photography abraham thomas
Aerial photography involves taking photographs from aircraft or other flying objects. It provides a synoptic view of large areas that allows for identifying small-scale features and spatial relationships. Interpreting aerial photographs involves detecting, recognizing, analyzing, deducing, classifying, and determining the accuracy of identified objects based on their tone, texture, pattern, shape, shadow, size, place, and associations with other objects. Key elements that aid interpretation include tone, texture, pattern, shape, shadow, and size.
Aerial photography- Concept and Terminologies
Aerial photography involves taking photographs of the ground from an elevated perspective using cameras mounted on aircraft or drones. The key aspects of aerial photography include:
- Photos have geometric distortions that can be corrected through photogrammetry to allow for accurate measurements, mapping, and 3D modeling.
- Factors like camera tilt, flight height, and relief displacement of objects must be accounted for.
- Aerial photos have specific scales depending on the flight altitude, and these scales are larger than typical maps, showing greater detail of a smaller area.
- Aerial photos find diverse uses in fields like geology, agriculture, land use planning, and environmental monitoring by providing overhead perspectives not available from ground level.
Map projection
This document discusses different types of map projections. It begins by defining map projection as a systematic drawing of parallels and meridians on a plane surface that corresponds to locations on Earth. It notes that all projections necessarily distort the surface in some way. Projections are classified based on their construction method, development surface, preserved properties, and position of the light source. Common projection types discussed include cylindrical, conic, azimuthal, Mercator, sinusoidal, and polyconic. The key properties and uses of each type are outlined. The document emphasizes that the purpose of the map determines the best projection to use.

The Earth is not a perfect sphere, but is slightly flattened at the poles. The Earth rotates daily on its tilted axis, causing seasons and influencing climate. Parallels of latitude and meridians of longitude form a grid system to locate positions on the Earth's surface. The Earth revolves around the Sun annually in an elliptical orbit, with the seasons resulting from the tilt of its axis of rotation. Precise geodetic coordinates define locations on the reference ellipsoid used to model the oblate spheroid shape of the Earth.
Map Projection
The document discusses three common types of map projections: Mercator, equal area, and gnomonic. It describes the Mercator projection as a cylindrical projection that accurately shows directions but distorts sizes, especially at the poles. The equal area projection represents areas correctly on the map using a conic projection. While it shows correct landmass sizes, it alters shapes. The document provides details on the characteristics and purposes of each projection type.

The Struve Geodetic arc & its future possibilities of being the one (Semester...
It is a concept that started in the year 1816 and was carried out by an astronomer by the name of Friedrich Georg Wilhelm von Struve. During the time of Struve’s existence, the distance between two points was measured by measuring poles.
However in order to accomplish the goal that Friedrich von Struve had envisioned - calculating the size of the earth - measuring poles would not be sufficient. To do this a more sophisticated tool would be needed.
Before long the Struve Geodetic Arc was created to do just that. The Struve Arc only ran through two counties, namely Russia and Sweden-Norway. But his surveys, that took place between the years of 1816 and 1855, calculated the very first measurement of a part of the meridian with staggering accuracy. It was the start of topographic mapping and a growing interest in earth sciences. The Struve Arc is a survey triangulation chain which has assisted scientists to map out certain areas and regions of their countries.

Webinar: Designing a schema for a Data Warehouse
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

GPS in Geodesy
- 1. Presentation on topic Using GPS in Geodesy Done by Student of IAN-415 Tkachuk Yaroslav
- 2. • GPS - Global Positioning System • Geodesy - a branch of applied mathematics and earth sciences, is the scientific discipline that deals with the measurement and representation of the Earth, including its gravitational field, in a three-dimensional time-varying space.
- 3. GPS technology allows to solve the geodetic problems of different levels: from the development of the state geodetic network to inventory land. Practice shows that productivity increases by in tens times.
- 4. Depending on the required accuracy of the coordinates, the time limit on the measurement conditions of work, apply GPS- receivers of different types, but they all work in differential mode and are phase. The most widely received in the CIS single frequency phase (L1) apparatus, because, on the one hand, the two-frequency 2-5 times cheaper, and, on the other hand, provides sufficient accuracy for most practical applications.
- 5. National Directorate of France CNASEA is working on the creation of an inventory of the former French colony of Mayotte. Required measurements on the territory of 375 square kilometre were performed for 15 days with using GPS- receivers PathFinder Pro XR from the company Trimble. When using traditional geodesic methods it would have taken about 15 years.
- 7. The specialists of JSC "ZapUralTISIZ" used a Trimble receivers 4000ST for work on the development of geodetic network in Ufa. Two- person crew built a triangulation of 15 points for 5 days, whereas the use the existing methods of geodetic measurements performs the same work team of five people for 2 weeks.
- 8. In general, the use of satellite location determination system greatly simplifies the work of surveying land, reducing the number of travel time and decreases the number of professionals involved.
- 9. Thank you for your attention!
