Land Surveying and Mapping

This includes cadastral, topographical, and engineering surveying. This is an aspect of spatial measurements, representation, analysis, retrieval, and display of spatial data concerning both the Earth's physical features and the built environment. Land surveying includes subsections such as cadastral surveying, engineering surveying, and topographical surveying. The different types of surveying carried out by Alliance Land Surveys Limited arise from its competencies in service provision and the technological skills of the company personnel.

GIS MAPPING AND SURVEYING

Alliance Land Surveys Limited has state-of-the-art facilities and knowledge for developing and interpreting information systems. The software used for GIS includes ESRI, and Arc GIS along with a spatial analyst and data automation kit, Auto Desk, AutoCAD, high-powered and map Server. The GIS division has in its inventory high powered CAD workstations, raster-to-vector, conversion utilities and software for processing satellite images. The GIS Division is capable of developing applications for land use information management, cadastral and utility mapping, and road infrastructure systems, urban planning, and development among other applications.

The main geo-information technologies promoted by Alliance Land Surveys Limited are Geographic Information Systems (GIS), Remote Sensing (RS), Global Positioning System (GPS) Surveys, land surveying, Database Development Systems (DBDS), Information Technology, capacity building and related services.

AERIAL PHOTOGRAPHY AND REMOTE SENSING

Is the acquisition of data from airborne and space-borne platforms. Aerial photography uses aerial photographs taken from a flying aircraft to space-born produce plan metric and topographical maps of the earth's surface (area of interest) and of features of the built environment.

DRONE MAPPING

Is the capture of high-resolution aerial imagery and data of a specified region of land using unmanned aerial vehicles (drones) outfitted with specialized cameras, sensors, and GPS technology.

This data is subsequently processed to provide precise maps, 3D models, and topographic representations of the studied area. This technique has various advantages over traditional surveying methods, including lower costs, greater efficiency, and the ability to explore difficult-to-reach or hazardous regions.
