MAPPING

 

Mobile mapping involves collecting geographic data using a mobile vehicle equipped with a variety of systems such as Global Navigation Satellite Systems, cameras, radar, laser, LIDAR, or other remote sensing technologies.

Photogrammetry, a discipline focused on extracting accurate measurements from photographs and digital images, often produces orthomosaic maps, symbolic maps, GIS layers, or three-dimensional (3D) models of real-world objects or environments.

Photogrammetric Mapping involves creating a detailed 3D model of a city, including complex structures, roads, electric lights, street lights and manhole covers. This process uses highly detailed 1/1000 or 1/500 vector mapping to achieve precision and accuracy in representation

High-resolution images are obtained using drones equipped with advanced cameras and sensors, and detailed maps are created based on these images. This technology takes less time and can be achieved at lower costs than traditional mapping methods. Capacity of Mapping DronesDrones can perform mapping tasks of different sizes and capacities. Equipped with high-resolution cameras and various sensors, these vehicles can collect detailed data by scanning large areas in a short time. This data is then processed with the help of various software and converted into usable maps. Data Collection Methods Data collection methods used in drones Mapping technology varies depending on the requirements of the environment and the project. Techniques such as photogrammetry and LIDAR are some of the most commonly used data collection methods with drones. While photogrammetry enables the creation of 3D maps by combining photographs taken, Lidar technology collects elevation data of the surface using laser beams. .Analysis and Reporting Process Evaluating and analyzing the collected data is one of the most important stages of the drone mapping process. The data obtained at this stage is processed using special software and reports are prepared according to the user’s needs. Reporting is created in accordance with the purpose of the project and may include detailed maps, modeling and measurements. Drone mapping allows for a better understanding of the area and more informed decision-making.

DATA DETECTION AND ANALYSIS

 

In the Data Detection Analysis study, all data regarding residential areas are collected and matched with graphical and non-graphical information, and queries and analyzes are performed. We update all buildings and streets with our current data detection application such as Geographic Information Systems, City Information System, Address Information System and National Address Data Update.
Geographic information, construction date, functions, features, construction quality, fuel type, heating system, home or workplace status of the projects and constructed buildings prepared in accordance with the “External Door Numbering Project” implemented by the Istanbul Metropolitan Municipality, its owner or its tenant. With this application status, elevator, parking lot and occupancy status can be easily determined.
In addition, the population structure of the district, neighborhood population, employment structure, day and night population structure, workforce characteristics and sectoral distribution can be determined. All this updated information is archived on the computer and we provide the fastest and most accurate information to the people of the district with satellite photographs.
Thus, citizens do not need to wait for tax and zoning procedures and address-based transactions in official institutions.

MULTISPECTRAL AND HYPERSPECTRAL DATA COLLECTION

 

Spectral imaging has become a valuable resource in fields ranging from agriculture to environmental management. Hyperspectral and multispectral imaging are key technologies in this field. Hyperspectral imaging provides detailed spectral information in multiple narrow wavebands, enabling in-depth material analysis and target identification. Although powerful, this method requires advanced data processing and expert analysis. Multispectral imaging, on the other hand, offers a more balanced approach by capturing fewer broad spectral bands. This compensation results in lower spectral resolution, but provides simplicity, cost effectiveness, and faster data throughput. Multispectral satellite constellations collect data across a limited portion of the electromagnetic spectrum (five to ten bands); typically RGB (red, green and blue – the three primary colors) and a handful of infrared bands. Hyperspectral satellites can distinguish thousands of individual light spectrum bands.

ADDRESS INFORMATION SYSTEMS

 

 

In order for the Address Registration System to be successful, the Numbering and Address Information System work must be complete and complete.
Numbering and Address Information System studies include numbering addresses in the field, hanging license plates and processing all addresses into the National Address System.
As one of the largest manufacturers in the field of Address Information Sign production and installation, we carry out all these processes smoothly, as well as domestic and international projects. We manufacture and assemble many door plates, especially in Istanbul, Izmir, Mersin and Kocaeli. Thanks to our production speed and quality, we are happy to be one of the largest companies in the sector in Europe and the Middle East.

 

NUMBERING

 

We start working by making the necessary determinations, accessing satellite photographs, and updating the data after the field trip. We number and install the license plates of all buildings, roads and streets.
We use technology in all the projects we carry out. After field determinations, we examine whether the map is up to date and then mark the outdated license plates via the computer.
After making the necessary site determinations with our experienced team, we list the entrances and exits, double entrances, street-facing facades and outdated numbers of all buildings and office buildings. We transfer the data stored on the tablet computer to the central server over the internet at the end of the day.
We manufacture and install new plates for completed roads and streets with the approval of the municipal authorities.

RFID SYSTEM

 

Radio Frequency Identification (RFID) is a technology used to identify entities or objects with radio waves. The reader in the system ensures that the radio waves coming from the RFID tag are converted into digital information and transferred to the computer system.

WHY RFID?

Door plates offered by RFID technology are no longer just plates showing the door number. We add an RFID tag to the plate according to the needs. Our authorized personnel in the field can access the necessary information about the building with a handheld terminal that can read RFID tags. When the RFID tag is scanned, the signal reaches the computer in the system. Depending on the barcode number entered into the computer, the data of the existing data is reflected. Thus, the door plate becomes more than just a table of door numbers consisting of a series of numbers symbolizing the whole of that structure.

DISASTER INFORMATION SYSTEM

 

With the Disaster Information System, we adapt technology to license plates and show our citizens where they should gather in case of disaster. We create an ID card for each building. 2D barcodes showing maps of the assembly area can be scanned with mobile phones.

 

DISASTER INFORMATION SIGNS

 

We carried out the Disaster Information Boards project with Beşiktaş Municipality and Izmir Metropolitan Municipality.

Agricultural Analysis

 

Aerial survey of fields allows farmers and agronomists to gain unprecedented situational awareness. Using appropriate tools, they can obtain comprehensive images of their fields and forests and collect data more efficiently than traditional methods. Collection and analysis of data plays an important role in decision making and increasing crop yields. Thanks to advances in software, sensors and drones, these processes are now more precise and effective than ever before.

AGRICULTURAL APPLICATIONS OF DRONE MAPPING

 

We create various maps to analyze agricultural productivity by taking advantage of the time-saving features of drones equipped with RTK/GPS systems and Multispectral Cameras. These maps are created regularly to assist in product development and disease control assessments. Initially, image matching techniques are harmonized, then 3D terrain models and ortho-mosaic images are generated from this synchronized dataset. Ultimately, maps used to evaluate product quality and supply, such as the normalized vegetation difference index (NDVI), are created based on previously created ortho-mosaic images.

CEMETERY INFORMATION SYSTEM
