Computer-aided design (CAD)

Data collected on paper is difficult to maintain, retrieve, analyze and interpret. many valuable documents could be lost or they may take too long to analyze and find the specific section needed. Since technology is evolving day by day solutions are coming up for each and every problems in all sorts of fields and computer aided design is the solution for this dilemma. Computer-aided design(CAD) is used in many fields and GIS benefits a lot from this particular service. Using this method not only can these documents be better preserved they can be easily found, modified, analyzed and interpreted. Since GIS uses a large amount of map based data, digitalization of these maps can prove to be very useful. The fields in GIS where this is particularly helpful is Georeferencing, parcel mapping, utility mapping, feature extraction and route network analysis. These fields use maps the most to find accurate and precise geographical data. Georeferencing is where maps are associated with real time co-ordinates locating different landmarks, places of interest. In parcel mapping, it fetches information on land, property for city planning and used by people like estate developers. In Feature extraction images are processed, vectorized and interpreted by different companies for different reasons. In utility mapping it helps finding the networks of different assets like pipes, electrical wiring etc used by people from the electricity board, water authorities etc. All of these can be hard and time consuming if paper maps are used. Instead if the maps are digitalized and used by a computer the process is made much easier and can be done much faster using the tools such as ‘find’ and other services. Last of all this is of the utmost importance for route network analysis where ambulances, fire engines etc need to find the fastest and easiest route to their destination. Using paper maps will be particularly hard because it cannot calculate the traffic and other obstructions. Also there might not be sufficient time to find the right route so there is a definite need to digitalize the map and use different computer systems to find the right and fastest route with no obstructions.

Unmanned aerial vehicles (UAV)

Unmanned aerial vehicles (UAV) known widely as drones or Remotely Piloted Aircraft (RPA) are vehicles which do not have a pilot inside to control it manually. These are controlled by onboard computers or by using a remote control. These can be used for multiple purposes especially in geographic information systems (GIS). Since they can easily collect better and more accurate, higher resolution pictures than a manned aircraft, UAVs are ideal for use in GIS. Digitalizing maps and viewing them in different layers in order to further study the elements on it in more detail is one of the most important things in the processing of the data collected using UAVs. This data can be interpreted and extracted by vectorizing to get precise information easily. Data collecting services include finding the height changes using (DEM) and (DTM), analyzing the measures, distances, positions, exact ground co-ordinates and removing the distortions. This data can be used for finding where certain objects or items on a map are such as a building or a place of interest, finding solar farms for use in solar panels, forecasting geographical data etc. These services are particularly used by military defense systems, finding energy sources for energy companies, town planning, for geological Investigations, finding mineral deposits in rocks, sources of ground water and so on.

Unmanned aerial vehicles are used by thousands of companies for different purposes throughout the world. SBL is one among the companies who provide the this UAV services with its many partners across the globe. SBL has a team of experts who interprets the inputs given by UAVs, perfects them and provide the information to you according to your needs.

Structural Mapping in geological distributions

The detailed analysis of the three-dimensional distribution of rock expressions with regard to their history of formation can be generally termed as structural geology. Estimation on the history of the formation/ deformation or in other words the strain which is seen in the rocks during the course of time through the measurements of present day rock geometries is the ultimate aim of structural geology. The information thus evolved can be linked to the events of the past. The geologic past of a region can be made from the information on the structural development of a particular region with regard to area wise distribution of the rock pattern distribution like that of mountain formation/rifting due to the effect of plate tectonics.

To make a definition, structural mapping can be termed as an identification or characterization of a structure. Structures comprise of faults, rock folds, synclines, anticlines and lineaments of rock formations. Thorough understanding of the rock structures is the key to understand the crustal movements of rocks that is responsible for the present terrain. Detailed examination of structure can be obtained by geophysical techniques such as seismic surveying.

The structural mapping gains much importance in the economic geology especially in petroleum geology and mining geology. The creeks and folds of rock strata can be a natural storage space for the fluids such as petroleum and natural gas. Thus the future of structural mapping becomes a prospective one in geospatial realm. Generally deposits of metals like gold, silver, copper, lead, zinc are located in structurally complex areas. Through accurate structural mapping solutions and services, we can identify the possible areas for mining such metals.

Mapping of structures forms a vital part of engineering geology, which generally deals with the physical and mechanical features of natural rock expressions. Structural formations like faults, foliations, joints and folds are internal defects of rocks which may seriously affect the stability of man-made structures such as dams, road networks, tunnels, open pit mines and underground mines. Another prospective area where structural mapping takes a major role is in mineral and hydrocarbon exploration along with potential hazard identification and its monitoring.

Other than being potential storages of oil and gas reserves by marking the underlying under-surface geometry of rock units and the effect of crustal deformation and stress experienced in a certain region, through structural mapping we get the clues to crustal movement and potential natural hazards, such as landslides, volcanic activity earthquakes etc.

SBL Geomatics, the Geomatics wing of SBL, an ISO accredited global ITES Company based in Cochin, India, weaves out its structural mapping solutions with accuracy and quality which no one else offers. The team is a pack of expert technocrats who make use of Remote Sensed data on the information on the surficial relief and spatial distribution of the structural elements to map the terrain accurately.

Photogrammetric Processes

Photogrammetry by definition means measurement from photographs. Here photographs being taken from an aerial platform like an air craft. These photos taken as stereo images need lots of processing before putting into actual usage. These processes are collectively known as photogrammetric processes. Stereo aerial photographs, ground control points (GCP), GNSS/IMU data and camera calibration certificates are the main input for a photogrammetric project. Photogrammetric services include processing these inputs to derive ready to use geometrically correct images. All these processing will be done in a suitable photogrammetric software platform. Aerial triangulation, bundle block adjustments, and stereo compiling are the preliminary steps of a photogrammtric process. During this process the photographs will be corrected for external as well as internal distortions. External orientation correction can be done using GCPs and tie points. Internal orientation corrections can be done using GNSS/IMU values and camera calibration certificates. Stereo viewing is possible after this stage of the processing. Now the terrain can be visualized in a 3D environment in suitable software platforms. Once the stereo compilation has done, digital surface models (DSM) can be generation from stereo models. Digital surfaces are nothing but visualization of the terrain not only on an x,y place but also with the z dimension in the form of elevation. Digital surfaces derived from the software platforms are with failed areas in many locations. These failures are due to cloud cover in images, shadows, or due to poor automatic compilation. These areas need to be corrected by editing the digital surface models. Corrected digital surface models are devoid of any collapsed areas. Ortho photos and Digital Terrain Model (DTM) can be generated using the digital surface models and stereo models. DTMs are bare earth models depicting the surface of the earth if there is not vegetation and artifacts over it. It is the true representation of the primitive earth surface. Many of the geological and other developmental projects require this sort of 3D models to know the exact and accurate height of the terrain with respect to the mean sea level. Other form of topographical maps such as contour lines, slope map, aspect map etc can be derived using these kind of 3D models. Ortho photos are another product which can be derived from these processes. Ortho rectified photos are geometrically corrected photos. Relief displacement and related distortions will also be corrected during ortho rectification process. These photos were later corrected for collapsed areas and then mosacicked to get a complete view of the area. Seam lines are commonly used for mosaicking of the images. The images thus derived can be color balanced to remove viewing of the seam lines and remove the difference to color saturation from image to image. Later images can be cut into tiles of desired dimension for easy usage. Once these kind of pre and post processing of the images are over, these will be put into use to derive information in the form of 2D and 3D feature mapping. Base mapping, land use land cover mapping and other kind of thematic mapping can be then be possible from these images.
